OPENING SESSION & KEYNOTE SPEAKER GEORGE KOUROUNIS

DATES: Monday, May 27 TIME: 7:30 – 9:15 am LOCATION: Victoria Conference Centre EXPLORING CLIMATE CHANGE AND WATER-DISASTERS THROUGH THE EYES OF A STORM-CHASER Global explorer, television host, and storm-chaser George Kourounis has a rather unusual relationship with water. From documenting rising sea levels that threaten entire nations like Tuvalu, to filming catastrophic floods in Canada and the U.S, to surviving devastating storm surges from hurricanes such as Katrina & Sandy, George has been on the front lines of our planet’s changing water-balance for 20 years. There’s too much of it in some places, not enough in others, and these shifts are expected to increase, putting more pressure on water management resources worldwide. He brings his unique perspective on the “rise of water” with exciting stories and keen insight from being in the thick of natural disasters and extreme phenomena across all 7 continents and 70 countries.

EDUCATION SESSION ABSTRACTS MONDAY

Underground Infrastructure Moderator: Yariv Ben-Shooshan

Room: Colwood

9:30 - 10:00 Logistics of Finding and Replacing Lead from Drinking Water Systems

Presenter: Timothy Phelan, P.Eng., P.E., AECOM

With Health Canada set to announce a reduced Maximum Acceptable Concentration for lead at the tap and the Province of British Columbia expected to follow, drinking water systems will need to understand the extent of lead use in their system and what to do with that information. Specifically, water systems will need to prepare a plan for how to find, document, and ultimately replace lead services in their communities. Based on the experience from across North America and including Flint, Detroit, Pittsburgh, the level of effort, schedule, and budget to replace lead will be presented. How different communities fund lead replacement and address the role of the homeowner will be compared. This will allow attendees to understand what could be needed and realistically achieved for their own system, whether they have a handful of lead services or 1000s of galvanized services. 10:00 - 10:30 Cleaning and Maintaining Large and Complex Water Systems - UDF and Hydraulic Modeling with the City of Victoria, BC

Presenter: Werner de Schaetzen, P.Eng. Ph.D., GeoAdvice Engineering Inc.

Flushing is one of the most effective tools available to maintain and improve water quality. Almost all municipalities use some form of flushing on a regular basis; however, these flushing programs are not typically sequential and often do not use valve isolation techniques. Last year, the City of Victoria invested in the development of a unidirectional flushing (UDF) program for the City’s water distribution system. For a system as large and complex as the City of Victoria distribution network, it is an extremely difficult feat to develop a perfect flushing strategy using experience alone, especially as the system and its customer base continue to expand. The use of the City’s hydraulic model and the development of an optimized flushing program ensure that every pipe is flushed in a safe and repeatable manner. The City UDF program consists of 150 flush zones and 1,400 UDF sequences and is one of the largest in BC.

MONDAY

Underground Infrastructure, continued 10:30 - 11:00 PVC Water Main Pipe - 40 Years of Successful Service

Presenter: Douglas Seargeant, P. Eng., Although currently retired, the presenter is sponsored by IPEX Inc. for this presentation

Water distribution system reliability is a primary concern for most water utilities. Not only do customers become dissatisfied when the water supply is not available when they want to use it, but the cost of responding to and repairing water main failures can put unwanted pressure on utility operating costs and associated rates charged to those customers. Failure rates vary between different pipe materials. PVC water main pipe has provided exceptionally reliable service for more than 40 years in some Canadian utilities. The results of testing of this pipe material have demonstrated its resilience.

This presentation provides a summary of recent testing of pipe after 40 years of service, as well as a number of other tests of PVC water main pipe conducted over a period of almost 25 years, combined with information related to actual water utility experiences with this pipe material.

Municipal Projects Moderator: Anthony Greville

Room: Esquimalt

9:30 - 10:00 You’re Welcome: The Annacis Island Stage 5 Odour Control Expansion

Presenter: Jaimie Hennessy, P.Eng., Brown and Caldwell

After odour sampling and developing an air dispersion model to aid in the evaluation of alternatives, the team identified opportunities to capture currently untreated sources, collect odour sources from new elements constructed as part of the Stage 5 project, and provide operational flexibility to Plant staff – all while expanding to include full n+1 redundancy for both the primary and secondary odour control treatment trains.

The odour control elements of Phase 1 of the Stage 5 Expansion includes treating currently untreated Screen Room and grit and screenings handling foul air streams, conversion of the existing scrubbers to combined caustic and hypochlorite scrubbing including new chemical storage and transfer facilities, as well as an upgrade of the primary odour and secondary odour biofilters to engineered media. The presentation will summarize the approach Metro Vancouver directed towards improving the performance and reliability of the odour control treatment processes at the Annacis Island plant.

MONDAY

Municipal Projects, continued 10:00-10:30 Kitimat Wastewater Treatment System Upgrade Presenter: Raymond Chin, M.Eng., P.Eng., WSP In 1950s, the BC government wanted to develop economic activity in northern BC and invited the Aluminium Company of Canada (Alcan) to investigate the opportunity. Kitimat was an excellent site for an aluminium smelter project. Alcan built a dam on Nechako River, 16 km tunnel, hydroelectric power station, 82 km transmission line, sea terminal, the Town of Kitimat and the smelter facility. The project took 5 years and a cost of $500Million; it was the most expensive private industry project at time. A decade later, in the 1960’s a sewage treatment plant was built for the town. It featured a single cell treatment lagoon. By 2014, economic activity in Kitimat was bustling. The smelter modernization project swelled the town population from 9000 to over 11,000. In addition, there were 2 proposals for LNG plants situated within Kitimat, with the potential to further increase the sewage loading. Meanwhile, the WWTP plant was essentially in it’s original condition from the 1960s. The District of Kitimat commissioned an audit of the Sewage Treatment Plant to plan for modernization and capacity expansion. This presentation provides a summary of the audit findings, grant application, design process and construction lessons from the WWTP upgrade. 10:30-11:00 Tofino Wastewater Treatment Plant 3D Design Process Presenter: Tyler Barber, P.Eng., WSP WSP was awarded the design for the new wastewater treatment plant and conveyance system for the District of Tofino and we elected to design the wastewater treatment plant using 3D modelling software. Our wastewater design team used Revit and Civil 3D, with several different disciplines, to model the five main process structures and site works for Tofino’s new treatment plant, creating a full 3D model to create design drawings. The structures include a headworks building, oxidation ditches, secondary clarifiers, dewatering building, and a large process-mechanical building. This presentation covers the pros and cons of using 3D modelling software for treatment plant design, the creation and presentation of deliverables using Revit, and lessons learned from the 3D design process. ______________________________________________________________________________________________

Raising the Profile of Water Moderator: Negin Tousi

Room: Oak Bay 1

9:30 - 10:00 All hands on deck: Engaging Industries and the Public in Climate and Water Sustainability Presenter: Jillian Doucette, B.Sc, GHG-IQ (carbon accountant), Synergy Enterprises, According to the most recent IPCC Report published Oct 2018, we have 12 years to change business as usual and avoid catastrophic climate change. Climate and water through global hydrology are inextricably linked. A single degree of warming causes 7% more moisture in the atmosphere, resulting in extreme conditions. Now, more than ever, we need an all-hands-on-deck approach to climate and water sustainability. Local governments are acting through regulative measures, but how do we meaningfully engage the unregulated industries and general public? Cities, countries and counties around the world have create programs and campaigns that raise awareness in these demographics. Synergy’s programs for commercial sectors in Tofino, Ucluelet and the Capital Regional District are one example. This session will review the link between climate and water, how engaging broader stakeholders can have the strongest return on investment and review best practices around the world for creating awareness and understanding that lead to a shift in behaviour. 10:00-10:30 Developing a public communications strategy for water conservation Presenter: Kris Etches, Metro Vancouver Metro Vancouver Regional District provides clean, safe drinking water though its member municipalities for 2.5 million residents. Climate change, population growth and other factors all contribute to the need for a long-term strategy for communicating the importance of water conservation to these residents, in order to reduce per capita demand and influence public attitudes towards drinking water. At Metro Vancouver, this strategy includes awareness and behaviour change campaigns, regulatory communications, and public outreach. This presentation will include the following:

• our work on understanding our audience’s attitudes towards water conservation and what we’ve learned from them;

• the development and implementation of a conservation campaign to create long-term behaviour change; • integration of regulatory communications with behaviour change communications; and • navigating the paradoxes of water conservation in a rainy climate.

Raising the Profile of Water, continued 10:30-11:00 It's Not Just Math: How Water Rates Drive Policy and Shape Your Community's Future Presenter: Kirk Stinchcombe, MES, MBA, PMP, Econics Setting water rates is challenging, but it’s not just a mathematical problem. When we increase rates or make changes to the rate structure itself, we implicitly move a cluster of different policy drivers. These decisions shape how our water systems perform, and ultimately what our communities will be like in the future. Key drivers include: • revenue sufficiency – do we have enough to run the system now and forever? • revenue stability – is the revenue stream consistent from year to year? • simplicity – do residents understand how they are being charged? Or why? • affordability – are rates as low as they can be? • sustainability – are we encouraging people to use water efficiently? • equity - are customers and customer classes being charged fairly? This presentation will share ideas about how to use water rates to drive your community’s policy goals. Along the way, it will provide some really useful tips and links to resources that will make the whole rate setting process less work and less of a hassle ______________________________________________________________________________________________

Water Treatment Moderator: Brian Barnett

Room: Oak Bay 2

9:30 - 10:00 Low biodegradability emerging contaminants in BC and Advanced Oxidation Process Presenter: Ian Wylie, Inc., MSc, CHTM, BI Pure Water Emerging contaminants and refractory or low biodegradable organics have been found in our environment, in the Fraser River, in the nearby ocean. BI Pure Water’s master chemist has been studying ways to treat synthetic organic compounds with Advanced Oxidation Processes for ten years. We look at the chemistry of these emerging contaminants or -- PAHs, BPAs, phenols & BTS, PCBs, EDC (endocrine disrupting chemicals) that are generally toxic for living organisms -- and how they can be treated. BC Pilot studies include:

• Vancouver legacy industrial site leachate/ Coal tar contaminated site • Phenol leachate from an Alberta landfill site • Vancouver Island landfill leachate • PFOS – fire retardants in water supply

Other wastewater treatment markets for AOPs:

• Sewage effluents, pharmaceuticals in sewage effluent • Pulp mill wastes • Optimizing biofuel wastes for energy generation

10:00-10:30 Sodium Silicate Corrosion Inhibitors: Chemistry, Testing Methods and Usage Protocols Presenter: Stephanie Rose, PQ Corporation Drinking water distribution and residential plumbing systems are subject to deterioration and internal corrosion, which results in the release of lead, copper and iron to the water. Lead release is of particular interest due to its harmful effect on human health. Utilization of optimized corrosion control programs are vital to minimize exposure and comply with the EPA’s lead and copper rule. Sodium silicate corrosion inhibition has been utilized for decades. However, due to the relatively widespread adoption of phosphates for corrosion control, there is very limited published information regarding testing methods and effective usage protocols for silicates. Successful corrosion control incorporating sodium silicate begins with understanding silicate chemistry and mechanisms in corrosion control. This paper will discuss application of this chemistry to achieve optimal performance through practical examples and review active research projects to address mechanistic consideration and biofilm control.

Water Treatment, continued 10:30-11:00 Microplasma-UV lamp as a new technology for UV-induced water purification and disinfection Presenter: Milad Raeiszadeh Oskouei, The University of British Columbia Drinking-water safety is an essential issue worldwide for the people in rural areas of both developed and developing counties. Consequently, there is a growing need for efficient and cost-effective water purifiers. Newly-emerged Microplasma-UV technology can be a viable alternative to conventional radiation sources for UV water treatment; which has come to be considered as one of the best water purification methods in the last few years. The capability of Microplasma-UV lamp to irradiate different wavelengths and frequencies with high intensity and in a flat form creates the opportunity for the development of novel UV-based water-purifiers. In this study, for the first time, application of Microplasma-UV lamp for water treatment was systematically studied. With the aim to assess potentials and efficiencies of Microplasma-UV lamp for the water disinfection, the UV-photoinactivation of E.coli bacteria and Bacteriophage MS-2 was examined as the most commonly-used surrogates for enteric pathogens evaluating the performance of drinking-water treatment processes. ______________________________________________________________________________________________ MONDAY

Room: Sidney

9:30 - 10:00 Assessment and management of GARP Well, Township of Langley, BC Presenter: Mark Bolton, P.Geo., M.Sc., Golder Associates Ltd. Given its close proximity to the Salmon River, Township of Langley production well FL Well #2 was identified as potentially being Groundwater at Risk of Containing Pathogens (GARP). Using the approach outlined in the BC Ministry of Health Guidance Document for Determining GARP, Golder Associates Ltd. and the Township conducted a Stage 1 screening, supplemented with Level 2 and Level 3 hydrogeological investigations, to identify and assess hazards to the quality of the source water for FL Well #2. In addition to the well’s location relative to the Salmon River, other hazards were also identified and required proactive management. This presentation will discuss how mitigation measures were implemented and a monitoring program was designed and implemented to build lines of evidence, reduce uncertainty regarding the source water quality and support a GARP determination.

Groundwater, continued 10:00-10:30 Groundwater Management for the City of Chilliwack Presenter: Jillian Sacre, M.Sc., P.Geo., Golder Associates Ltd. The City of Chilliwack, with its population of 80,000, is entirely supplied by groundwater from the Sardis-Vedder Aquifer. A groundwater protection plan developed for the City represented the first of its kind in BC. Now, 20 years later, the plan has been updated to provide not only for the protection of groundwater quality, but for the sustainability of the groundwater resource in the context of future demands and climate change. Groundwater modelling was undertaken to assess the impact of groundwater withdrawals on nearby streams. A capture zone analysis, contaminant inventory and risk analysis were conducted to assess potential threats to groundwater quality. Subsequent work included the assessment of Environmental Flow Needs for creeks that are recharged by the Sardis-Vedder Aquifer in support of the City’s groundwater licensing application under the Water Sustainability Act, together with test well drilling to investigate the potential for expanding the production well network. 10:30-11:00 The Future Water Supply of the Gibsons Aquifer Presenter: Dave Newman, AScT, Town of Gibsons The Town of Gibsons domestic water system is comprised of three pressure zones. While Zone 1 and Zone 2 are supplied by groundwater wells in the Gibsons Aquifer, Zone 3 is supplied by the Sunshine Coast Regional District. Through the implementation of universal water metering, public education, and follow up leak tracking and repairs, the Town has effectively reduced their per capita water demand from 800 lcd in 2008 to approximately 350 lcd in 2016 and 2017. As a result of this reduction in water demand and aquifer mapping, the Gibsons Aquifer now has potential to supply all three Town pressure zones. In order to supply current Zone 3 MDD from the Gibsons Aquifer, a new booster station is required, as well as a check valve and water main extension to fully separate the SCRD and Town water systems. A new groundwater production well will be required to service future water demands of the Town of Gibsons. ______________________________________________________________________________________________

1:30-2:00 Pipe Leak Damage Prevention Presenter: Robin Parker, P.Eng., Kerr Wood Leidal Associates Ltd. Pipeline failure can undermine soil and structures around it. When placed in a sensitive environment, additional precautions may be warranted to protect the pipe and the surrounding assets. The alignment of the Clover Forcemain in Victoria warranted additional measures due to its proximity to steep bluffs and valuable shoreline habitat. To reduce risk, alternative designs were developed, including double-wall pipe and trench dams and/or foundation drains installed to divert ground water to storm drains. A multi-objective decision analysis methodology was developed to evaluate alternatives. A risk matrix was developed to assess 19 possible mechanisms of failure and consequences. A net risk score was assigned based on the relative likelihood of correlated consequences of failure, which was reduced by each potential mitigative measure that could be implemented in a practical and feasible manner. The result is under construction as we speak and is located only 1 km south of the conference. 2:00-2:30 The Challenges of Building Large Water Mains in Urban Areas Presenter: Anita Le, P.Eng., PMP, Jacobs Engineering To serve the anticipated population growth in the Lower Mainland, installing larger water infrastructure in dense urban centers is critical. Many obstacles accompany these unique installations, including heavily congested utility corridors, constructability issues, and major infrastructure crossings; the Kennedy Newton Annacis Main No. 5 Project (KNA) addresses these issues head on. Located in Surrey, one of the fastest growing cities in BC, this new-build project includes approximately 11 kilometers of 1.8-meter diameter pipe and several large, buried chambers. To fit the new main into congested utility corridors, key design considerations include impacts to existing infrastructure, accommodating future installations, and major crossings. Moreover, to ensure a successful project, constructability factors must be considered early in the design. As projects like this become increasingly necessary, KNA serves as a baseline to guide the design of future larger water infrastructure.

Underground Infrastructure, continued 2:30-3:00 Sundial Creek and the Spider Excavator Presenter: Randy Colombo, Eng Tech, City of Coquitlam In 1958 a 600mm concrete storm pipe was installed in the Chineside neighbourhood of Coquitlam. The outlet is in a 24 m deep ravine with a 57% slope making accessibility extremely difficult. In 1974, a large poured in place headwall structure was installed on the outlet of the pipe to dissipate the water energy due to increased flows from development in the catchment area. A recent inspection discovered that the headwall structure had broken away from the pipe and fell several feet. During rain events, the water exiting the pipe was hitting the back of the structure and severely eroding the steep banks putting properties above at risk. The ravine had over 40 years of growth, and the properties at the top of the ravine on both sides are completely developed making access even more difficult. It was necessary to get materials and equipment down the ravine slope to repair the headwall and stabilize the slope, however our options were very limited due to the access issues. This paper will discuss these challenges in detail along with how the Coquitlam team dealt with them. ______________________________________________________________________________________________ MONDAY

The project install Micro-Hydro power generation system within the Village's water supply as well as upgrade the Village's water treatment system to include Ultrafiltration treatment. This presentation will review the Village of Nakup's Micro-Hydro Power Generation System and Water Treatment Plant Upgrades to Ultrafiltration. It will include project timelines, project objectives, obstacles encountered and resolve to these obstacles as well as provide qualitative and quantitative results from the project. As an example, Micro-Hydro power provides $30K revenue to the Village and the project was completed with a 5 year payback. 2:30-3:00 White Rock Design Build Treatment Plant for Arsenic and Manganese Presenter: Saad Jasim, Ph. D., City of White Rock The City of White Rock's water utility is committed to providing safe and clean drinking water to its residents. The drinking water is obtained from the Sunnyside Uplands Aquifer using 7 wells located throughout the City. Elevated concentrations of naturally occurring arsenic and manganese are found in the water supplied from the Sunnyside Aquifer. The City received an award from the Clean Water and Wastewater Fund (CWWF) for the construction of a water treatment plant to reduce arsenic and manganese in its drinking water. The Design Build project consisted of a Pre-Oxidation with Ozone followed by Greensand Plus for the removal of manganese, and by Bayoxide E33 for the removal of arsenic. The construction of the plant started in March 2018, and the project is expected to be completed by March 2019. ______________________________________________________________________________________________

The New Normal - Climate Change Moderator: Don Nash

Room: Lecture Theatre

1:30-2:00 Aiming for Moving Goal Posts: B.C. in a Changing Climate Presenter: Kari Tyler, M. Ed, Pacific Climate Impacts Consortium Climate change is already occurring and when we continue to use historical data or make decisions based on historical experience then the information that we are using is not representative of the present or the future. This session will introduce relevant future climate information and resources in B.C., present new resources from the Canadian Centre for Climate Services and highlight provincial actions in B.C. The session will also include an experiential exercise to learn how to integrate future climate information into their existing practise. 2:00-2:30 Resilient and adaptable – two keys to future survival Presenter: Chris Howorth, P.Eng., Veolia The debate on climate change has progressed from “is it real?” to “what can we do?”. The water industry is closer to the natural world than most, meaning we face some of the biggest challenges. Because water is the single most consumed resource, we also have huge potential to reduce society’s environmental impacts. Water and wastewater treatment are among the key areas where responses to these threats and opportunities are needed. This presentation encompasses:

• Recent western Canadian experiences where treatment technology was called on to help overcome significant climate related events;

• Projects in BC and further afield where technologies were selected to prepare for such events in future; • A drinking water collaboration project involving governments and Canadian universities that will help BC

communities prepare for forest fires; • Projects that have enabled municipalities to reduce their environmental footprint.

The New Normal - Climate Change, continued 2:30-3:00 Climate Change Impacts and Adaptation Options for Water Utilities in Western Canada Presenter: Lalith Liyanage, Ph.D., P.Eng (BC, Alberta, Yukon), Stantec Consulting Ltd Adaptations to avoid or reduce climate change impacts on water and wastewater infrastructure systems requires knowledge of past and future trends of climate variability and predicted impacts of climate change on the local climate. In addition to the direct impacts on water wastewater infrastructure, there is potential secondary impacts due to the climate change impacts on watershed, agriculture, economy, and social/behavior. Without a knowledge of the future tendencies in the coming years and decades most decision makers will have a limited technical capacity to address adaptive management practices and having appropriate policies for planned adaptation to climate change. This presentation will provide a toolbox of technical options, discuss policy and management options available for planning, implementation and available responses to specific impacts. ______________________________________________________________________________________________ MONDAY

1:30-2:00 Top 8 issues facing wastewater facilities in treating high strength wastewater Presenter: Jonathan Lee, B.Comm, M.Sc Candidate, Acti-Zyme Products Ltd. The economic, operational, environmental and regulatory drivers for maintaining a sustainable treatment process in treating sources of high strength wastewater is becoming increasingly difficult for Wastewater Treatment Facilities (WWTFs). These pressures arise as increased levels of organics in wastewater sources are finding their way to WWTFs causing system capacity issues, with decreased ability to reach regulated treatment levels. With regulation in some provinces and upcoming regulation in others, there remains a significant need to fully understand the issues surrounding the increased levels of organics found in WWTFs. This paper looks to cover a few effects and implications of high strength wastewater in municipal WWTFs by diving into some of these issues. Topics covered will include the Phosphorus and sludge build up, collection line FOG blockages, Industry waste streams, disposal, and handling of hauled septic sewage, effects of Polymer usage, system optimization and acid mine drainage.

Wastewater, continued 2:00-2:30 Raising awareness for sustainable management of biosolids in the BC interior Presenter: Stephen Horsman, P.Eng., WSP Few municipal services experience the level of public misconception and inherent process risk as the management of wastewater solids. Facing evolving regulatory conditions, increasing financial pressure, immediate vulnerabilities in composting production and market capacity and growing uncertainty in public perceptions, the cities of Kelowna and Vernon sought to develop a biosolids management strategy designed to address both the immediate and longer-term vulnerabilities within the processing and ultimate beneficial reuse of their wastewater solids. With the current operations culminating in the production of a “Class A” compost, the cities have been reliably generating a high quality soil amendment product since 2006. This presentation will navigate the cities’ holistic approach to develop a sustainable biosolids management strategy that seeks to be both environmentally and economically responsible. Topics will include treatment process technologies, a beneficial reuse market analysis, diversification strategy throughout the process, regional processing opportunities and outcomes from an initial public engagement process. 2:30-3:00 Implementing composting toilet systems in BC and worldwide Presenter: Claire Remington, University of Victoria Composting toilets are innovative and appropriate for many contexts as they 1) reduce water consumption, 2) reduce downstream expenses, operational inefficiencies, and nutrient pollution associated with conventional treatment and disposal of sewage, and 3) recover nutrients into compost to improve soil quality. This work shares lessons learned from the installation of a composting toilet at the University of Victoria Campus Community Garden including an overview of the relevant regulatory framework, opportunities for future research, and discussion of local and international contexts where the implementation of composting toilet systems is preferable given the constraints of conventional sanitation designs. Composting toilets demonstrate the opportunity for a “new normality” in the form of a sanitation system that operates ecologically by conserving water and producing a valuable soil amendment. ______________________________________________________________________________________________

Room: Oak Bay 2

1:30-2:00 Drinking Water Safety Plan for the Capital Regional District, Victoria Presenter: Christoph Moch, Dipl.-Ing., P.Eng., Capital Regional District Within the Greater Victoria Drinking Water System (GVDWS), the CRD provides source water, water treatment and bulk water supply to six municipal water distribution systems, and retail water supply within another six municipalities. As typical for an unfiltered drinking water system, managing water quality risks becomes especially important. In 2016, the CRD undertook a comprehensive assessment of over 400 risk factors that could adversely affect water quality. The project identified and ranked a number of known but also previously unknown water quality risks. Because of the work undertaken, the CRD is equipped with a valuable tool that helps identify, prioritize and mitigate risks, and a document that provides a basis for informed, credible and defensible decision making moving forward. An overview of the comprehensive field assessment work undertaken over a year long period and the final project outcomes will be provided in this presentation. 2:00-2:30 Optimization of drinking water treatment during specific climatic events Presenter: Caetano Dorea, Ph.D., University of Victoria Optimization of drinking water treatment requires appropriate monitoring tools and good operational knowledge with regard to raw water quality and treatment processes. For surface water sources, specific hydroclimatic conditions (i.e. droughts, floods, heavy rainfalls, etc.) that lead to changes/degradation of raw water quality (i.e. turbidity and natural organic matter) can complicate the plant’s operation and possibly compromise the finished drinking water quality. The objective of this study was to assess the treatment resilience during specific rainfall events by analyzing drinking water treatment performances. This work was conducted in a facility supplying approximately 50 000 customers. We analyzed the routine operation of the station to establish an operational reference in terms of water quality parameters (turbidity and UV absorbance in raw and filtered waters) followed by an analysis of the treatment response to raw water quality degradation events. A resulting operational strategy to optimize water treatment operation is proposed and discussed.

Drinking Water Safety, continued 2:30-3:00 Drinking Water Source Protection Plans in a changing climate Presenter: Marta Green, P.Geo., Associated Environmental Consultants Inc. Drinking Water Source Protection Plans are a common condition of a large water system’s permit to operate, and are an important part of the multi-barrier approach. Source Protection Plans involve first inventorying potential hazards, and then ranking them by risk level using a likelihood of occurrence and magnitude of consequence matrix. Next, mitigation measures are developed to lower the risk, or, if the risk isn’t manageable, an emergency response plan is recommended. Several source protection plans that the author has completed for municipal groundwater supplies in southern Interior and Coastal BC over the last few years will be re-examined with a lens on a changing climate, specifically, what hazards may be more likely to reach the water supply, and/or, result in a higher consequence than previously thought. ______________________________________________________________________________________________ MONDAY

Risk Management, continued 1:30-2:00 Municipal Systems: Legislative Tools for Inter-departmental Risk Management Presenter: Rina Thakar, LL.B, LL.M, Civic Legal LLP Municipal water and wastewater systems are facing ever-increasing risks and liabilities associated with population growth, natural hazards and other environmental factors such as climate change. Inadequate supply and service, flooding, and infrastructure damage to water and wastewater systems can have long-lasting negative effects on the health, safety and well-being of communities across BC. Fortunately, municipal owners and operators of these systems have at their disposal various legislative tools to manage and reduce these risks and liabilities. This session will outline these tools, with a focus on how different local government departments can work together towards proactive, early and co-ordinated implementation of some of these strategies, to reduce negative impacts on their communities. 2:30-3:00 Physical Security Protection for Water Utilities Presenter: Rob Grant, P.Eng, PBX Engineering A review of trends in physical security that are applicable to Water and Waste Water facilities, including CCTV, card access, perimeter security, and vehicle and pedestrian access control. Presentation will be vendor agnostic and will focus on guidelines and recommendations for technology, including emerging solutions such as video analytics.

3:15-3:45 Inline Work without Shutdown Presenter: Brandon Pater, A.Sc.T, Pacific Flow Control Ltd With higher demands on our aging underground infrastructure, it has become necessary to keep our utilities live while new capital work and maintenance are underway. In some instances, live work is required due to missing, bypassing or inoperable valves. This information session will give you a general overview of the three main technologies that allow you to work inline without shutdown: hot tapping, line stopping and valve insertion. Subsequently, we will look at several case studies and discuss the best options to work without shutdown, avoiding leaving large numbers of people or high-risk clients without service. 1. Langley - WWTP – 12” Reinforced Concrete Wall – 24” Hot Tap 2. Delta - Bypass Hot Tap & Line Stop a 30” C301L PCCP line 3. YVR Runway Expansion – Line Stop and Full Bypass on HDPE Pipe 4. Port McNeill - Valve Insertion and Bypass on C900 3:45-4:15 Influent Channels Inspection at Annacis Island WWTP Presenter: Gary Skipper, P.E., Brown and Caldwell Metro Vancouver (MV) Operations identified a flow split issue in the existing Annacis Island Wastewater Treatment Plant (AIWWTP) Influent Control Chamber (ICC) that channelizes flows to the Influent Pumping Station (IPS). Brown and Caldwell Consultants Canada, Ltd. performed computational fluid dynamics (CFD) modeling to analyze the facility’s existing hydraulic configuration, as well as potential improvements, if a flow imbalance was confirmed to be present. Identified improvements were incorporated into the Phase 2 IPS Improvements detailed design, construction contracts and construction engineering services (CES). This presentation will describe the multi-phased inspection and condition assessment services for the Influent Junction Chamber (IJC) structure, 4270 mm (14 feet) wide by 2135 mm (7 feet) high IJC channel, ICC structure and the IPS screen channels successfully performed by Brown and Caldwell Consultants Canada, Ltd.

Underground Infrastructure, continued 4:15-4:45 Direct to the Point in Victoria, BC Presenter: David Houghton, E.I.T, ENV.SP, AECOM Urban environments have challenged utility service providers for centuries and as populations grow there is no shortage of new challenges in the foreseeable future. Providing wastewater treatment and conveyance for the Capital Regional District (Victoria, BC, Canada) provides several new challenges to overcome, including delivering a cross-harbour undersea wastewater conveyance pipe through a seismically sensitive urban area. Because the new WWTP will be on one side of a waterway that separates the City of Victoria, a new conveyance pipe had to be installed under the harbour from Odgen Point to the new plant at McLoughlin Point. The design called for a 1 meter diameter steel pipe to be installed on an alignment reaching a depth of 80 meters below sea level for a total length of approximately 950 meters. The conveyance line was successfully delivered with minimal impact to the surrounding community and environment using Horizontal Direction Drilling. ______________________________________________________________________________________________ MONDAY

3:15-3:45 City of White Rock - Setting the New Standard for Arsenic and Manganese Removal Presenter: Larry Sawchyn, P.Eng., McElhanney Consulting Services Ltd. / Colliers Project Leaders White Rock captures water from groundwater wells containing Arsenic and Manganese with levels under the Guidelines for Canadian Drinking Water Quality. Though meeting the guideline, the community set out to prove a higher level of treatment was viable. Early practice for arsenic removal was to find another source as the cost of managing residuals was prohibitive. Continued use of the source water with a cost-effective higher-level treatment defined the community’s challenge. The project began with a joint research program with ResEau to prove treatment. The community then successfully completed a grant application from the Clean Water and Wastewater Fund and shared their research to the water market to provide a Design-Build solution to achieving the new higher standard. This presentation will share how the community built from that pilot, validated the design and the planning process to maintain the upgraded plant once it becomes operational by March of 2019.

Stakeholder Engagement, continued 3:45-4:15 Surpassing Regulatory Requirements to Future Proof A Regional Wastewater Treatment Facility Presenter: Hayden Porter, Jacobs Engineering Extensive stakeholder engagement for the $900 million Northwest Langley Wastewater Treatment Plant expansion indicated a disconnect between the regulatory minimum treatment level and the desire of stakeholders to protect the environment. Key issues raised during the consultation process included concerns about effluent impact on fisheries and recreation, desire for tertiary treatment, and desire for minimal odour. In response, the project team investigated technologies and developed a series of stepwise improvements to the effluent and the associated costs. A series of workshops were convened with project decision makers in 2017-2018 to determine the acceptable balance between affordability and public expectations. The key outcome was the Metro Vancouver Board approval of the following, which surpass minimum regulatory requirements and provide future-proofing capabilities:

1. Conventional activated sludge process upgraded to biological nutrient removal including year-round nitrification and an extended solids retention time to provide improved removal of contaminants and emerging substances of concern.

2. Tertiary filtration to reduce particulate load and micro-plastics discharged to the Fraser River. 3. Odour control to minimize offsite impact by meeting an odour criterion of 1 OU/m3 at the nearest sensitive

receptor. This project demonstrated that meaningful stakeholder engagement and providing decision makers with a range of options and benefits provided the impetus for selecting an enhanced treatment level and that the cost premium provided a high-value improvement. 4:15-4:45 It Takes a Village to Lift a Boil Water Advisory Presenter: Megan Wood, P. Eng., M.A.Sc., WSP The Village of Middle River lived under a boil water advisory (BWA) for close to 14 years, following a series of water treatment attempts. The challenges associated with providing safe drinking water to this remote, northern community, proved too daunting for a conventional project approach. WSP and RES’EAU-WaterNET aimed to address this by building upon prior research initiatives, adopting a Community Circle approach together with Tl’azt’en Nation and partners from the public and private sector. The result was the implementation of Canada’s first full-scale biological ion exchange (BIEX) water treatment system, and the lifting of Middle River’s long term BWA in late 2018. This presentation will cover the history of water treatment in the community, issues that contributed to the long term BWA, the efforts taken towards implementing a BIEX treatment system, and the impact on the community since the lifting of the water advisory. ______________________________________________________________________________________________

3:15-3:45 Drinking Water Management in British Columbia Presenter: Lori Berndt, Auditor General for Local Government The office of the Auditor General for Local Government has conducted several audits on local government drinking water management in B.C. We will review and discuss our audit findings and good practices gathered during our recent audits and through the development of our AGLG Perspectives Series booklets on this topic. The AGLG's goal is to help local governments fulfil their responsibilities to be accountable to their communities for how well they take care of public assets and achieve value for money in their operations. The AGLG Perspectives Series booklets are designed to help local government's improve their performance. These booklets complement the AGLG's performance audit reports by providing local governments across the province with tools and more detailed information relating to the topics we examine. 3:45-4:15 Decision Protocols for Cyanobacteria in B.C. Drinking and Recreational Water (version 2) Presenter: Rupert Benzon, Ministry of Health Cyanobacterial blooms in drinking water supplies and recreational water bodies are challenging to both communities and regulators. Predicting the timing, magnitude, duration, and potential health impacts of cyanoblooms is difficult, notwithstanding that they often recurring events. The BC Ministry of Health has developed decision protocols to assist health authorities, local governments, and water operators in responding to cyanobacterial blooms and toxins in BC drinking water and recreational water. These protocols provide standardized processes to follow when monitoring cyanobacterial bloom events, and are available on the Ministry of Health website at https://www2.gov.bc.ca/assets/gov/environment/air-land-water/water/waterquality/how-drinking-water-is-protected-in-bc/cyanobacteria_decision_protocol_2018.pdf With this presentation, the audience will be introduced to highlights from the updated (2018) protocols for both drinking and recreational water. Key recommended actions to address cyanobacterial bloom and associated microcystin toxin issues will be discussed.

Water Quality, continued 4:15-4:45 What municipalities should know about PFAS Presenter: Jesus Garcia Aleman, P.Eng., PhD, Jacobs Engineering Per- and polyfluorinated alkyl substances (PFAS) are a group of more than 3,000 synthetic chemicals used as surface coatings (textiles, carboard, non-stick cookware), industrial additives, and fire-fighting foams (airports, chemical facilities and fire training areas). PFAS have been found in most human blood samples collected worldwide and linked to health effects in several species. PFAS have been identified in WTP and WWTPs influents, biosolids and landfill leachates in several studies. Health Canada has established drinking water screening values (DWSV) for 9 PFAS and British Columbia regulated several PFAS in drinking water. PFAS are persistent and resist most conventional W and WW treatment technologies. However, water treatment with granular activated carbon, ion exchange, or reverse osmosis have proven effective in removing PFAS albeit at much higher treatment and disposal costs compared to other compounds. Additional treatment techniques are being evaluated (advanced reduction, advanced oxidation, co-precipitation and adsorption). ______________________________________________________________________________________________ MONDAY

Energy Optimization/Recovery Moderator: Julie Gardner

Room: Sidney

3:15-3:45 Navigating the opportunities for distributed energy recovery and generation Presenter: Steven Conrad, Ph.D, University of British Columbia Distributed Energy Resources (DER) are an emerging opportunity for water utilities to offset the increasing energy demand and costs for water services. Self-generation of energy may reduce costs, improve system resilience and reliability, and reduce GHG emissions. Renewable forms of DER available to utilities can include organic matter in wastewater, hydropower, thermal heat in wastewater, waste heat from converting gas, to electricity, solar and wind. These forms of energy can potentially generate far more energy than their sites require. This presentation will summarize findings from research on DER to guide utilities, related stakeholders and policy makers interested in pursuing DER. The presentation will speak to Opportunities for DER at Water and Wastewater Utilities, the DER Regulatory and Policy Environment, DER Risk and Success Factors, and Lessons from DER Implementations (Case Studies). The main focus of the presentation will be on energy generation, but other elements of DER resource integration (energy storage, demand response, and micro-grids) are touched upon.

Energy Optimization/Recovery, continued 3:45-4:15 Energy Implications Associated with Carbon Diversion in Phosphorus Removal Facilities Presenter: Dean Shiskowski, Ph.D., P.Eng., Associated Engineering “Energy neutrality” and “carbon diversion” are topics of new-found interest for facilities that use enhanced biological phosphorus removal (EBPR) as most in cold-weather climates use primary sludge (PS) fermentation to produce some of the short-chain volatile fatty acids (VFAs) needed to drive EBPR biochemistry. From an energy perspective, side-stream PS fermentation ultimately diverts some fraction of wastewater carbon away from anaerobic digestion (AnD) systems, which in turn reduces biogas production potential. In addition, the carbon directed to anaerobic bioreactor cells to support EBPR ultimately increases the biomass oxygen demand, and thus aeration energy inputs, in the aerated bioreactor cells. In light of these considerations this presentation describes a whole-facility, simulation-based evaluation conducted on a typical process configuration used in western Canadian wastewater treatment facilities. Sensitives related to wastewater characterization, fermenter and AnD performance are explored and used to inform an energy-centric EBPR versus EBPR / chemical P precipitation comparison. 4:15-4:45 Decoupling Aeration, Mixing Achieves 70% Energy Savings in Aerobic Digestion Presenter: David Mullins, EnviroMix, Inc. The City of Benton, IL, a 1.65 MGD facility, is utilizing a system of decoupled aeration and mixing in its aerobic digesters to realize over $40,000 (USD) in annual energy cost savings. The energy-efficient mixing approach referred to as “compressed gas mixing” utilizes large bubbles created from short bursts of compressed air released through nozzles mounted to the basin floor. When used in conjunction with a right-sized diffused aeration system, Benton, IL realized significant benefits including process improvements, energy savings, and automated operation through instrumentation feedback. ______________________________________________________________________________________________

Small Water Systems Symposium Moderator: TBC

Room: Saanich

1:30-2:00 Small, Old and Six Feet Underground – Improving a Small Water System with Shallow Wells Presenter: Keith Kohut, M.A.Sc., P.Eng., Associated Engineering Associated Engineering was retained by the Bridge River Indian Band to upgrade the drinking water systems for two of their communities located in the Fraser Canyon area. The area is known for dry and hot summers, and finding adequate drinking water supplies is always challenging. This presentation walks through some of the challenges that are common for many small water systems in the area, and how these challenges were overcome, including:

• Finding water in an area where supply is scarce or of low quality • Working out treatment and water supply protection for wells classified as GARP/GUDI • Upgrading existing infrastructure that is either undocumented or in an unknown condition • Adding alarms and a monitoring system • Minimizing confined space entry infrastructure • Troubleshooting problems with the older infrastructure that revealed themselves when the new

infrastructure was added 2:00-2:30 Pilot Testing – Success Through Water Operator and Engineer Collaboration Presenter: Grant Dixon, LGA, ATAP Every source water has different chemical and physical parameters. This creates unique challenges for selecting the pre-treatment, and treatment, process train. This will challenge both the Water Operators, and Engineers when looking into the design an operations of a water treatment facility. The most effective way to deal with this challenge is to undertake sampling and/or pilot testing programs. This presentation will discuss how sampling and/or pilot testing programs will improve long-term project success through collaboration between the Water Operator(s) and Engineers from the start of design. We will cover the following topics in our presentation:

• Understanding our source water, and its chemical and physical characteristics • Understanding historical data and how it helps future design and upgrading • Pilot testing – small investment, big returns • Pilot testing when, why and how an effective program is developed • Water Operator collaboration to ensure pilot testing success • Developing and understanding effective operating programs before the water treatment facility is built • How pilot testing lowers the risk of project failure when designing and operating new, or upgraded facilities • Case studies of effective and “ineffective” pilot programs

Small Water Systems Symposium, continued 10:00-10:30 Case studies of package water treatment systems in small communities Presenter: Deanne Mould, BA, BI Pure Water, Inc. Utilizing package water treatment systems to upgrade your community`s water infrastructure on a tight budget: employing membranes, UV, media vessels, and ion exchange units. How engineering consultants spec them and some best practices. Case studies of; • Kamloops , Vernon, Vancouver Island and Powell River subdivisions • Faulder, Okanagan, BC, uranium water treatment plant • First Nations communities: Middle River, Lytton 10:30-11:00 UV-LED Water Treatment Systems: A Global Solution for Efficient Water Disinfection Presenter: Babak Adeli, PhD, Acuva Technologies Ingesting microbiologically contaminated water is among the most common sickness routes for people living off the grid. Ultraviolet radiation is the most effective water disinfection method. However, conventional UV-lamp based water purifiers cannot be utilized for off-grid applications, due to their high electrical power requirements and frequent maintenance. On the other hand, ultraviolet light emitting diodes (UV-LEDs) based water treatment systems enable low energy consumption and maintenance-free operation. Here, we elaborate the advantages of UV-LEDs water treatment systems and present the results of several case studies for benchmark microorganisms, such as E.coli, Total Coliform, T1UV, and MS2. Further, effectiveness of UV-LED water treatment devices will be explained through case studies on the off-grid disinfection of Grand River and Laurel Creek. It is shown that UV-LED systems operated on 15VDC can provide microbially safe drinking water from contaminated water sources, which are identified unsafe for not only drinking, but also recreational activities. ______________________________________________________________________________________________

8:00-8:30 Major Population Growth in A Unique Way – Model Development, Calibration and Analysis of the City of Coquitlam’s Northwest Sewer Collection System Presenter: Werner de Schaetzen, P.Eng. Ph.D., GeoAdvice Engineering Inc. Many communities in BC have challenges managing their existing sanitary sewer systems. Those communities have to maintain adequate service levels, accommodate growth, manage high inflow and infiltration rates, and replace aging infrastructure, all within a limited operating and capital expenditures budget. The City of Coquitlam, BC Northwest sewer system currently services approximately 45,000 residents, with an aggressive growth strategy in the Coquitlam Centre area that will increase that population by nearly 6 times. To address the challenges of such significant growth, the City has decided to re-develop a detailed hydraulic model of their sanitary sewer system to review the robustness of their system and identify and prioritize performance upgrades. 8:30-9:00 Assessing Densification Impacts on Residential Water Demands Presenter: Neal Whiteside, MASc, PEng, Water Street Engineering Ltd Metro Vancouver undertook a study to forecast changes to water demand that could occur as a result of residential densification, with a time horizon of 2041. This presentation documents how base and seasonal (summer) demand metrics for existing residential water usage in Metro Vancouver were developed. The work disaggregated residential water demand by season (base demand and seasonal demand), by municipality (for the municipalities providing data), and by housing type (various types of detached residential and multi-family use). The study analyzed meter records from over 88,000 dwelling units from five local governments in Metro Vancouver. Over 1,000 detached and multi-family residential sample areas were digitized to develop irrigable area estimates for each housing density type. The water demand metrics were then projected for a land-use forecast. The results show how residential densification is expected to produce striking changes in per capita unit demands.

Demand Management, continued 9:00-9:30 Water Quality and Hydraulic Performance of High Flow Rate Bioretention Presenter: Joel Garbon, BS Appl Sc, Imbrium Systems As cities densify and storm events intensify, innovative green infrastructure solutions are required to manage urban stormwater runoff. In recent years, novel bioretention systems have been developed with high flow rate media, demonstrating vastly superior stormwater infiltration rate as compared to conventional bioretention installations, and requiring a footprint that is typically one-tenth that of standard systems. Water quality performance has also been enhanced in the newer design, and treatment is remarkably robust and consistent for key stormwater pollutants of concern such as total suspended solids (TSS), phosphorus, and heavy metals such as copper and zinc. Field monitoring data for multiple installations in diverse regions of the U.S. and Canada, in addition to presentation of the key features and treatment mechanisms within the high flow rate bioretention design, provide valuable insights into long-term water quality and hydraulic performance expectations. ______________________________________________________________________________________________ TUESDAY

8:30-9:00 Adapting Flood Protection Measures for Climate Change Presenter: Eric Villeneuve, P.Eng., District of North Vancouver In November 2014 extensive debris flooding occurred in the District of North Vancouver which caused widespread damage to homes, roads, creeks and drainage infrastructure. In response, the District implemented a prioritized debris hazard mitigation infrastructure program to replace aging and undersized infrastructure and install new debris flood mitigation structures. Since 2015, implementation of the program has included construction of several debris basins, barriers and culverts, and designs for additional mitigation measures are underway. In November 2018, the debris flood mitigation infrastructure was tested when two 5-year rainfall events hit the North Shore within three days. The storm events caused flooding of several properties and debris flood accumulation which damaged District infrastructure (culverts and roads) on several creek systems. However, no substantial flooding occurred at the locations protected by the infrastructure recently installed indicating initial success for the newly implemented flood mitigation program.

The New Normal - Climate Change, continued 9:00-9:30 Climate Change is the New Black (But It Might Put You In The Red) Presenter: Adrienne Atherton, LL.B, Civic Legal LLP As population growth and climate change place pressure on water and wastewater systems, owners and operators are taking advantage of increased federal funding and investment opportunities to upgrade and expand existing infrastructure. With the growing number of water and sewer upgrade capital projects come a host of construction-related risks and issues. In this session, we will discuss common causes of potentially costly construction delays and disputes, and the tools available to owners to secure effective delivery of the construction project on-time and on-budget, and minimize the risks of disputes. 10:45 - 11:15 Avoiding Water Wars in Time of Drought Presenter: Olga Rivkin, Lawyer - water, municipal, environmental, Lidstone & Company Law Corporation The prospect of water shortage is alarming for many reasons. Obviously – people cannot live without water. Less obviously – authorities providing water may start waging water wars to protect what they see as their resources. In British Columbia, legislation is not adequate to protect water suppliers from water wars. We will examine why and what can be done to address the shortfall. ______________________________________________________________________________________________

8:00-8:30 Cybersecurity - Are you Vulnerable? Presenter: Andrew Yick, P.Eng, M.Eng, Spartan Controls Critical infrastructure such as water & wastewater treatment plants and pumping stations have significant cybersecurity risks and threats. This presentation will discuss best practices around improving cybersecurity for SCADA and Control Systems. The discussion will discuss applicable codes/standards, security enhancement techniques and risk mitigation strategies. 9:00-9:30 Case Study of Smart Sensors, Data Technology and Source Control Presenter: Kati Bell, Ph.D., P.E., Brown and Caldwell One of many goals of a wastewater utility is to ensure there is enough hydraulic and organic treatment capacity in the collection system and treatment plants to provide conveyance and treatment of sewage. This is concurrent with meeting discharge permits as well as protecting public infrastructure. Understanding the timing and quality of discharges to the system can enable a utility to more efficiently maintain asset integrity and discharge permit compliance. This presentation will provide an overview of City of Memphis challenges, and their path forward to gather and manage real-time data on industrial discharges into the collection system. While simply having more data does not address source control issues, a discussion will also be provided on the data platform and related analytics that allows operationalization of the advanced monitoring data, allowing the City to address related deterioration of collection system assets and impacts to the biological process at the WWTPs. ______________________________________________________________________________________________

8:00-8:30 Municipal natural asset management: opportunity for water professionals Presenter: Roy Brooke, Municipal Natural Assets Initiative Local governments are rethinking how they become more resilient and deliver services reliably and cost-effectively. For a growing number of Canadian municipalities this means looking at existing natural assets such as forests, riparian areas and coastal ecosystems for answers. Increasingly, local government experience in municipal natural asset management suggests that healthy and well-managed natural assets can provide some of the same services as engineered assets but with lower capital and operating costs and greater resilience to a changing climate. A growing body of evidence suggests that seizing this opportunity means more resilient Canadian communities. This presentation describes: the rationale for and evolution of municipal natural asset management; the development of the Municipal Natural Assets Initiative; lessons from Gibsons and the first Cohort; the business case for including natural assets in asset management strategies; and the particular role that water professionals can play in encouraging natural asset management. 8:30-9:00 Regionalization for Water Systems: 1 Lessons for British Columbia Presenter: Laith Furatian, Ph.D., City of Kamloops Since the beginning of the modern era of drinking water regulations in the 1970s, law makers in North America have acknowledged that compliance by smaller systems would be difficult. Many assumed that following the passing of such laws some form of regionalization would follow, whereby smaller systems would aggregate into larger entities that could reduce financial, technical, and labour challenges using greater economies of scale. But for the most part, such restructuring has not materialized, and small systems continue to struggle to provide safe water supplies. Though some successful efforts at regionalization have occurred, and it is a growing trend globally, it is not yet widespread in North America. This paper reviews examples where regionalization has been advanced as a solution to address the challenges faced by small water systems with specific emphasis on identifying the challenges most applicable to the British Columbian context.

Municipal Utility Management, continued 9:00-9:30 Regionalization for Water Systems - 2 The Current Debate in New Zealand Presenter: Jim Graham, MSC (ENV Studies), BSC (ENV Sci), Dip Env Health Sci, Dip Water Assessor, Water New Zealand Two years since contamination of the Havelock North drinking water supply in New Zealand resulted in more than 6000 people becoming ill with campylobacteriosis and 4 deaths, the National Government has instructed officials to reform regulatory arrangements for drinking water. Officials have also been instructed to investigate options for regional aggregation of the 67 municipal water suppliers into perhaps five publically owned corporate water entities. British Columbia like New Zealand has a high number of relatively small municipal water suppliers, poor compliance with standards and many boil water advisories. While a single event hasn’t precipitated the debate as it has in New Zealand, at some point British Columbia may need to consider if regionalization will provide better outcomes for water consumers. This paper critically examines the benefits and disbenefits of regionalization, currently being debated in New Zealand and anticipates those most likely to be relevant in British Columbia. ______________________________________________________________________________________________ TUESDAY

Wastewater Treatment Moderator: Ronald Enns

Room: Esquimalt

9:45-10:15 Using Reactive Filtration to Achieve Ultra-Low Phosphorus and Metals Targets Presenter: Dalen Crouse, Nexom With phosphorus-fed algae blooms plaguing many North American bodies of water and the danger of metals rising in the public consciousness, regulators are putting increasing pressure on wastewater treatment facilities to meet ever-lower phosphorus and metals limits, down to micrograms per liter. Additionally, there is also challenges placed on municipalities to achieve more with less – meaning using the most reliable treatment system available, while simplifying operations and minimizing both capital and life-cycle costs. In this presentation, we will cover a broad overview of available techniques for phosphorus removal and how installations currently seek to meet regulatory limits and introduces the concept of reactive filtration to achieve ever lowering limits. This presentation will then explain the reactive filtration process’ adsorption/reaction kinetics and how it improves on traditional sand filters’ particle coagulation and filtration, while also being relatively simple and affordable to operate and maintain.

Wastewater Treatment, continued 10:15-10:45 Practical Field Techniques and Methods to Assess Secondary Clarifier Performance Presenter: Joyce Chang, Jacobs Engineering In a wastewater treatment facility, secondary clarifiers are crucial for producing effluent that meets regulatory limits for total suspended solids prior to discharge. In 2001, the Water Environment Research Foundation (WERF) and Clarifier Research Technical Committee (CRTC) published a guidance document on protocols for evaluating secondary clarifier performance. Metro Vancouver operations staff have been regularly assessing the performance of secondary clarifiers at the Northwest Langley Wastewater Treatment Plant using the dispersed suspended solids/flocculated suspended solids (DSS/FSS) tests described in the WERF/CRTC protocol. Besides the regular tests, Metro Vancouver also conducted a 2-month intensive clarifier test program in 2017, with additional DSS/FSS test points beyond the standard WERF/CRTC protocol. This presentation will provide an overview of the test program, demonstrate DSS/FSS sampling techniques using a Kemmerer sampler, present two years of data, and highlight key lessons learned. DSS/FSS test data, combined with dye test results and microscopic observations of microorganisms, illustrate how field data can be used to assess a clarifier’s hydraulic performance and assist operators in identifying where to focus efforts on improving overall plant performance. 10:45-11:15 Managing Settlement Risk during Brownfield Construction: The Annacis Experience Presenter: Dave Newman, P.E., Brown and Caldwell The Annacis Island Stage 5 Expansion included a comprehensive program to address future post-disaster performance and manage risks to existing infrastructure during construction of the Plant expansion. More than 5,000 30-metre deep stone columns were installed, over 1 kilometre of 30-metre deep cement-soil mix (CSM) cutoff walls were constructed to isolate existing infrastructure from impacts due to dewatering for the new construction, and more than 430 real-time settlement prisms are monitored for impacts to existing structures. The program also included a strategy to manage dewatering water (~20 ML/d) by treating it at the existing Plant. However, the Plant experienced an unforeseen risk when the poor quality of the groundwater resulted in a process upset. Operations staff mobilized a temporary, stop gap chemical treatment program for the full Plant flow (>500 ML/d) to maintain OC compliance, while project staff developed a longer term chemical treatment system to address the isolated dewatering stream. ______________________________________________________________________________________________

9:45-10:15 Wetlands and their Role in Climate Adaptation Strategies Presenter: Carrie Nadeau, R.P.Bio., Associated Environmental Consultants Inc. Wetlands are natural buffers that absorb, store, filter, and slowly release water back into the environment, helping to mitigate climate change. Wetlands reduce flow volumes discharged to streams, improve water quality from runoff, improve flow management during flood and extreme weather events, and reduce flood risk impacts on infrastructure and property. Climate change adaptation strategies include education, development, and implementation of municipal bylaws to conserve, construct and restore wetlands. Two planning tools, recently developed in the Okanagan, will be presented: Constructed Stormwater Wetlands Guidebook, and a Wetlands Toolkit. Effective ways to use wetlands in climate change adaptation strategies will be discussed including: how to determine if your project site is suitable for a treatment wetland, what type of wetland is suitable (i.e. water treatment), how to appropriately size and construct a wetland, and wetland conservation and restoration strategies in relation to flood risk, drought mitigation and infrastructure protection. 10:15-10:45 Environmental flow needs in a time of change Presenter: Nelson Jatel, Dr.(c), MA, BSc, Okanagan Basin Water Board In the Okanagan, fish are directly experiencing the effects of climate change – shifting hydrologic regimes, warmer waters, and habitat loss. The contemporary regulatory book on Environmental Flow Needs (EFN) in British Columbia is under development. The Okanagan has different conditions than coastal streams, and it has required new, regionally-appropriate approaches. The process of developing defensible Okanagan EFNs for sockeye, kokanee and rainbow trout has spotlighted the urgency and need to integrate climate change effects in underlying naturalized flow data. These climate change impacts, visible in current hydrology data, are influencing local water management, policy, and governance. This is the story of how the changing environment in the Okanagan’s lake and river systems has influenced EFN development. Studies and research, applying traditional and scientific knowledge, are supporting proactive approaches to climate change adaptation that will influence fisheries, water suppliers, agriculture and the health of riparian areas.

The New Normal - Climate Change, continued 10:45-11:15 Gated Harbours and Sea Level Rise Presenter: Colin Kristiansen, P.Eng., MBA, Kerr Wood Leidal Associates Ltd. Adaptation to Sea Level Rise may include closing off BC harbours in the future. The first such plan is being developed for Steveston Harbour. It involves turning the Steveston Island breakwater into a dike and placing a large gate at the harbour entrance. Few adaptation projects in BC will have as much of a visual impact on our landscape. Much of the stakeholder consultation to date has focussed on the opportunities these changes bring. ______________________________________________________________________________________________

We will give an update and overview of the new online systems and upcoming changes. We will touch on the workforce strategies project and work being done with the Canadian water and wastewater operators certification committee. 10:15-10:45 Social Procurement - Procuring for Water & Wastewater Capital Projects beyond the Lowest Bid Presenter: Sonia Sahota, P.Eng., LL.B, Civic Legal LLP As population growth and climate change place pressure on water and wastewater systems, owners and operators are taking advantage of increased federal funding and investment opportunities to upgrade and expand existing infrastructure. The last few years have seen (and likely the next few years will see) a large uptake in the number of water and sewer upgrade capital projects being procured for construction. While “lowest price” may still be the common sentiment among seasoned stakeholders in the construction industry, a whole new perspective on purchasing priorities is taking shape. Social procurement is more than a buzz phrase, particularly for public owners of large capital projects. This session will explain what social procurement encompasses and how some communities are embracing the change. 10:45-11:15 Partnering with the Province: It’s about Building Relationships Presenter: Laird McLachlin, Ministry of Municipal Affairs and Housing This presentation will highlight how the City of Kamloops and the Province worked together to deliver two key infrastructure projects that were supported by capital grant funding. The delivery of the North Thompson River Emergency Water Intake and the Juniper Creek Bank Stability projects will be explored with a timely discussion about managing these capital works. Staff from both the City and Ministry of Municipal Affairs and Housing will discuss their perspectives on navigating this process from start to finish. Key insights will be shared about the strengths of collaboration and information sharing throughout this process to deliver robust projects which benefit our communities. ______________________________________________________________________________________________

1:15-1:45 Weaving Through the Complexities of Constructing Large Diameter Water Mains in Urban Areas Presenter: Peter Gates, P. Eng., PE, PMP, Colliers Project Leaders Metro Vancouver is a working partnership of 21 municipalities, one electoral district, and one treaty First Nation. The Greater Vancouver Water District is operated by Metro Vancouver, and is responsible for delivering a safe, reliable supply of drinking water to approximately 2.4 million people in the region. As a significant number of Metro Vancouver’s large diameter water mains are reaching the end of their service lives, the construction of these water mains requires public engagement, route selection, traffic control and key preliminary designs. Colliers Project Leaders and Metro Vancouver’s discussion will provide an outline for the preliminary design, detailed design and construction of a large diameter water main in an urban area based on lessons learned from previous Metro Vancouver projects. We will provide valuable insight into how better planning and design can greatly reduce the challenges faced in future construction projects. 1:45-2:15 Upgrading Metro Vancouver’s Critical Coquitlam Plant with Zero Service Interruption Presenter: Negin Tousi, B.A.Sc, EIT, WSP Located within the protected Coquitlam Watershed in British Columbia, with a capacity of 1,200 ML/day, Metro Vancouver’s Coquitlam Water Treatment Plant is one of two plants providing safe drinking water for over 2.5 million residents. WSP worked with Metro Vancouver to replace the existing gas chlorination system, an essential step in the disinfection process, with a new liquid system to improve reliability and safety. This conversion was completed by employing a temporary liquid system prior to decommissioning the gaseous system. The transition between the three systems (gaseous, temporary liquid, and permanent liquid) without service interruption carried unique challenges, requiring significant coordination and planning amongst Engineers, Contractors, Operators, Industrial Software Specialists, Electricians, Commissioning Specialists, and Safety Officers. Presenting alongside Metro Vancouver’s operations staff, Negin Tousi will speak to the unique design and construction processes that allowed for the safe conversion from gas to liquid chlorine systems with zero interruption to service.

Current water supplies can operate near capacity during the summer. The project goal is to improve water security for both the City of Parksville and the RDN. The project includes a new river intake, a membrane filtration facility and distribution upgrades. The project will augment the water supplies of both the RDN and the City of Parksville, providing a safe reliable drinking water source throughout the year. The project is in the final stages of construction, with process commissioning scheduled to take place in mid-2019. This presentation will describe the design background, regulatory drivers and process selection. It will look at the use of technology to manage costs and risks and review the value engineering required to meet budgetary goals. Lessons learned will also be shared. ______________________________________________________________________________________________ TUESDAY

Storm Water / I&I Moderator: Jonathan Hung

Room: Oak Bay 1

1:15-1:45 New National Standards for Design and Construction of Bioretention Systems Presenter: Laurel Morgan, M.Sc., P.Eng., Kerr Wood Leidal Associates Ltd. Designing and implementing bioretention systems (also known as engineered rain gardens) present a complex array of challenges. To address this, experts from across Canada collaborated in the development of the new standards for design and construction of bioretention systems. The design standard provides a very detailed template for how to design a bioretention system that is robust, resilient, and meets regulatory targets. The construction standard provides detailed processes and information to plan, oversee, and inspect the installation of a bioretention system that will function as intended. These standards are meant for use Canada-wide, but must be cited by a regulatory authority to have regulatory weight. In BC, this would typically be local and regional municipalities, which have authority over stormwater bylaws and policies. This presentation will describe how these standards can be useful to municipalities and when the standards might be more relevant than other guidance documents.

Storm Water / I&I, continued 1:45-2:15 LEED v4 and City of Vancouver New Stormwater Criteria Presenter: Michael Thiessen, P.Eng., McElhanney Consulting Services Ltd The new stormwater criteria in Canada Green Building Council’s LEED v4 and City of Vancouver’s Infrastructure Rainwater Management Plan depart from the previous emphasis on rate control in favour of volume control. This shift represents a water balance that is closer to pre-development conditions. This presentation will explore how to efficiently design and comply with the criteria and how they compare to each other at different locations around Vancouver. While the City’s criteria remain static across Vancouver, LEED criteria become more onerous with higher rainfall. This will be demonstrated with 2 case studies that utilize different strategies for compliance. 2:15-2:45 Private Side Flood Protection and Reduction of I&I Through Canada's Building and Plumbing Codes Presenter: Dan Sandink, MA, MSc (Pl), Institute for Catastrophic Loss Reduction Recent funding focussed on mitigation of the potential impacts of climate change on Canada's built environment have significantly raised the profile of I&I and basement flood risk within Canada's code and standards development agencies. Several projects funded through the National Research Council and the Standards Council of Canada, which emphasize private-side mitigation of I&I and basement flood, have been developed, including a new national guideline on private-side basement flood protection (CSA Z800-18). These projects will lead to the development and submission of code change requests aimed at mitigating private-side basement flood I&I risk through Canada's National Model Building and Plumbing Codes. The presentation will review four recent projects commissioned by federal agencies, including the National Research Council and the Standards Council of Canada. A series of potential code change requests will be presented, which emphasize protection of homes from flooding associated with short-duration, high intensity rainfall events, and management of I&I on the private side of the property line. ______________________________________________________________________________________________

1:15-1:45 Water Distribution Seismic Resiliency – Evaluating Existing Piping Presenter: Neal Whiteside, MASc, PEng, Water Street Engineering Ltd The City of Surrey’s water distribution system includes a variety of material types and covers a range of different ground conditions. The water system services high-density urban and industrial uses as well as low-density rural areas with a corresponding range in redundancy (amount of looping). The presentation will identify methods used to evaluate expected water main repair rates following an earthquake, criticality and developing plans to address identified vulnerabilities. Recent seismic performance of water distribution mains and systems (in particular following the 2011 Christchurch earthquake) will be reviewed. This recent empirical experience was used to develop useful relationships for forecasting water main repair rates based on material type, expected peak ground velocities, and permanent ground deformations. Development of performance goals, mitigation strategies, and capital planning to address seismic risks will be discussed. 1:45-2:15 Advances and Current Practices for Earthquake Resistant Water Distribution Piping Presenter: Allan Bronsro, PEng, Water Street Engineering Ltd Many water utilities updated their seismic design criteria for water piping in the late 1990s following a series of damaging earthquakes (Loma Prieta, Northridge, and Kobe). Subsequently, the Christchurch events in 2011 caused over 1600 pipe failures/repairs, which have been studied in detail. Also since 2000, new pipe products designed specifically for earthquakes, particularly permanent ground deformation, have become available in North America. These factors are facilitating new reviews of seismic practice in many jurisdictions. The presenter will review newer piping products, selection criteria such as ISO 16134, testing done at the University of Cornell, as well as evolving practice in several relevant cities such Surrey, Vancouver, Seattle, Oakland, and Los Angeles.

Risk Management, continued 2:15-2:45 Engineering for Emergencies - A Backup Water Supply for Kamloops Presenter: Liam Baker, P.Eng., City of Kamloops The City of Kamloops' water source, a direct intake off South Thompson River, is susceptible to contamination due to busy highway and rail traffic, and heavy industry upstream of the intake. An emergency backup intake and pump system was designed and built on the nearby North Thompson River. Design challenges included extreme high/low river levels, deep wet well, fish friendly intake structure/screen/pump system, and a requirement that no in-river maintenance allowed. Integration into the existing distribution network was critical to ensure that during emergency the system could be brought on line without hiccups. The presentation will focus on the rationale and planning behind the intake, the execution, design, and construction, testing and commissioning, and challenges moving forward. ______________________________________________________________________________________________ TUESDAY

3:00-3:30 Metro Vancouver’s Innovative Use Options for Drinking Water Treatment Residuals Presenter: Karen Pyne, AScT, Metro Vancouver The Metro Vancouver owned and operated Seymour Capilano Filtration Plant supplies clean, safe drinking water to 2/3 of the 2.5 million residents within British Columbia’s Metro Vancouver Regional District. The plant treats the source water using alum for coagulation upstream of filtration, which generates approximately 10,000 tonnes/year of alum-based drinking water treatment residuals. From the commissioning of the plant in 2010 until 2016, these residuals were disposed of at the local landfill. Metro Vancouver is committed to recovering resources from waste materials, and has actively investigated beneficial use opportunities for the residuals. Through an innovative joint project, the local Lafarge Cement Plant is now using this residual product as a raw material alternative for red shale. Metro Vancouver is also exploring the phosphorus-binding capabilities of the residuals. This presentation will provide more detail on these alternatives to landfilling of alum-based drinking water treatment residuals.

Innovation, continued 3:30-4:00 Fortress Mountain Resort - The Rise of Potable Water in A Year Presenter: Nick Rauch, EIT, McElhanney Consulting Services Ltd Fortress Resort required a team to raise water to the top of the ski hill for potable water distribution to the resort community. The project required delivery of the upgraded treatment plant within 11 months and construction meeting a 5 month weather window in the mountain region. This required design and tender of the plant, conveyance infrastructure, and all auxiliary components in 6 months. Constructability of a robust plant meeting regulatory compliance required a unique methodology to meet the challenges. We will present the design innovations and project execution plan followed that streamlined activities including a creative approach to going to the market for the upgrade. In addition to the delivery of a new water plant delivering safe and reliable water services to the Resort, the client added a water bottling facility to expand into the marketing of cannabis infused water. 4:00-4:30 Vancouver Heatwave Response: Temporary Drinking Fountains and Misters Presenter: Laura Hosokawa, City of Vancouver During extreme heat advisories, in addition to other cooling measures like opening cooling centres and handing out bottled water, the City of Vancouver deploys 12 temporary drinking fountains and 3 misting stations to serve the vulnerable populations: the homeless, the elderly, and the very young. The infrastructure connects to the potable water supply via hydrants and hosebibs. Multiple city departments and external agencies are required to coordinate efforts and communications in order to place temporary fountains where they can serve the transient population effectively but do not impact other city infrastructure or safety requirements. The demand for temporary drinking fountains and misting stations is growing from organizers for festivals and events, bike lanes and underserved areas in parks and playing fields. Allocating the limited supply of temporary infrastructure requires defining sufficient access to water, and prioritizing other City programs like Access to Water, Zero Waste, and Green Infrastructure. ______________________________________________________________________________________________

3:00-3:30 Non-potable reuse – the pros, cons, costs and benefits Presenter: Kati Bell, Ph.D., P.E., Brown and Caldwell There is a variety of “low hanging fruit” – non-potable reuse projects to diversify community water supply portfolios. Many applications (landscape irrigation) only offer seasonal benefits while requiring installation and maintenance of dual distribution systems. Indoor uses of non-potable reclaimed water, including toilet flushing and urban agriculture, along with potable reuse of highly purified water continues to grow to guard against climatic variability. Key risks in indoor use of non-potable reclaimed water are accidental cross-connections and opportunistic premise plumbing pathogens, e.g. Legionella. With a 400% increase in Legionellosis outbreaks in the U.S. since 2001 (not linked to reuse), the industry must consider the causes to avoid outbreaks linked to reclaimed water. This presentation provides an overview of opportunities in non-potable reuse and challenges that remain - premise plumbing issues, salinity and nutrient management, and regulation and implementation of decentralized systems, which may ultimately drive communities toward potable reuse. 3:30-4:00 A Reclaimed Water Demonstration Facility - Comparing Disc and Membrane Filtration Presenter: Lynn Stephens, P.E., Brown and Caldwell The Greater Vancouver Sewerage and Drainage District (the Corporation) is looking to assess the effectiveness and economic feasibility of implementing a reclaimed water program at the Lulu Island Wastewater Treatment Plant, with the implementation of a reclaimed water demonstration facility. This project is part of the Corporation’s goal to conserve potable water and recover all elements in wastewater as energy, nutrients, water, or other usable materials. To evaluate this project’s feasibility, Brown and Caldwell developed a Predesign Basis Report and Preliminary Operational Plan documenting the design approach and to assess the operation and maintenance (O&M) requirements for the demonstration facility. Both membrane treatment and disc filtration were evaluated for the study. This presentation will cover the evaluation process, design criteria, and O&M assumptions used for the demonstration facility. ______________________________________________________________________________________________

3:00-3:30 A Case Study on Reactive Stormwater Management in the qathet Regional District Presenter: Julia Stafford, EIT, Associated Engineering The qathet Regional District (qRD) (formerly known as the Powell River RD) is a relatively remote collection of coastal communities spanning from Saltery Bay to Lund, accessed by two ferries from the Lower Mainland. qRD is unique in the fact that there are very few formal bylaws in place to regulate development, which indirectly has a significant impact on stormwater management. The Ministry of Transportation and Infrastructure (MoTI) has a partnership with the qRD to install and maintain the network of surface drainage systems throughout the region. However, a lack of drainage planning during land development, and unchecked modifications to the natural drainage pathways have contributed to problems in the form of flooding issues and coastal erosion. Associated Engineering was retained to assess the state of the current drainage system, and recommend stormwater management measures to enhance the drainage system as future development and climate change will intensify existing problems. This study highlights the importance of developing unified drainage standards and bylaws for sustainable stormwater management, and the resulting issues when this planning is not adequately carried out. Stakeholder engagement was an important component of this process, to both inform our understanding of the key local issues related to stormwater management and acceptable/actionable ideas for solutions. The qRD region provides an excellent case study to illustrate how three independent groups, MoTI, the qRD, and residents must corporate to form proactive stormwater management strategies in the context of a changing climate 3:30-4:00 City of Maple Ridge Design Storm Update Presenter: Wendy Yao, P.Eng., Aplin & Martin Consultants Ltd. The design storms previously used by the City of Maple Ridge were derived based on the AES BC Coast distributions for events less than 12-hour durations and the SCS Type 1A distribution for 24-hour duration events. A review performed to these design storms shows that intensities of the 24-hour duration design event appear being high, greater than those for the 2-hour, 6-hour and 12-hour duration events. A further review to a number of selected historical events indicates long duration storm events recorded in the region were more uniformly distributed and did not contain intense bursts of rain as shown in the SCS Type 1A. Using the SCS Type 1A distribution to develop 24-hour duration design storms would result in oversizing infrastructure in the urban areas especially for detention facilities and the City’s major drainage system that are more expensive to build and upgrade. Aplin Martin has therefore performed a comprehensive review to the actual storm distribution patterns based on the historical rainfall data collected in the region, generated rainfall distribution curves for various design durations that reflect real storm characteristics in the region, and then used these updated distribution curves to generate design storms for the City of Maple Ridge. We believe using the updated design storms, the infrastructure designed and constructed would be more reliable, conservative as well as cost effective.

Storm Water / I&I, continued 4:00-4:30 Integrating Your Infrastructure into the Community - Richmond No.2 Pump Station Presenter: Simon Kras, P.Eng., WSP The City has developed a Flood Protection Strategy help them adapt to challenges associated with climate change. The No.2 North Drainage Pump Station was upgraded to help meet the goals of this strategy. The design of the pump station aimed at aesthetically integrating the pump station into the community. A local artist was brought on during design to help achieve this. The building ultimately featured glass wall construction to showcase the MCC and genset, giving trail users access to municipal infrastructure. HVAC was run through subfloor ducting, an innovative design allowing the glass wall building. Other design aspects include a wing shaped roof which collects rain water, a functional hand pump to move storm water, and a revitalized dike trail near the city centre. ______________________________________________________________________________________________ TUESDAY

Water Treatment, continued 3:30-4:00 The Continuing Evolution of Membrane Gravity Filtration (MGF) Applications: Recent Case Studies and Development Presenter: Simon Breese, M.A.Sc., P.Eng., AECOM In 2017, Peel Region in Ontario, Canada began an 18 ML/d full-scale trial at the Lorne Park WTP of Suez Water’s “MGF” membrane-based gravity filtration technology. A first of its kind, the goals were to develop how conventional filtration could be easily replaced and improved with a similar and solely gravity-based membrane technology. MGF technology is a direct drop-in conventional media replacement utilizing simplified submerged membranes using the same open-tank gravity head, backwashing pumps, piping arrangement and air scour blowers as conventional filters. There is no need for underdrains or backwash troughs typically associated with conventional filters. MGF does not need additional pumps nor the usual complex appurtenances associated with typical membrane solutions such as cleaning/neutralization equipment and tankage. Due to the reduced stress on the gravity membranes because of the lack of harsh cleaning, there is inherently less fibre breakage and fibre repairs maintenance. This presentation will build upon Simon's presentation given at BCWWA 2018, firstly to update the industry on the continuing performance of MGF at Lorne Park including long-term permeability and innovative integrity solutions that have been applied to date. Lessons learned will be provided and how that is being applied in new applications. New MGF applications will be case studied as to the drivers for selection and current status in terms of design, development and operations for new applications. This includes the very first permanent facility in Colorado which is commissioning in the fall of 2018 and other applications in the development stage in Ontario, Canada up to 185 ML/d. Within these case studies, comparison of cost, capital and operations will be provided and show the potential for cross-process impacts in other treatment solutions that may be possible as the technology evolves showing diversity in approaches that can be met with MGF. Furthermore, since MGF in a regulatory sense is somewhere between conventional dual-media filtration and low-pressure membranes, a synopsis of the continuing discussion will be provided as to the response from regulatory approval agencies in the licensing and approval of MGF facilities to date. ______________________________________________________________________________________________
