To: Water Committee From: Larry Chow, Program Manager, Quality Control, Water Services Date: April 6, 2020 Meeting Date: April 30, 2020 Subject: GVWD 2019 Water Quality Annual Report RECOMMENDATION That the Water Committee receive for information the report dated April 6, 2020, titled “GVWD 2019 Water Quality Annual Report”. EXECUTIVE SUMMARY The GVWD Water Quality Annual Report is used by both Metro Vancouver and the member jurisdictions to fulfill reporting requirements to the regional Health Authorities. For 2019, the Capilano, Seymour and Coquitlam reservoirs were continually in service and provided excellent quality source water. Performance at the Seymour Capilano Filtration Plant and Coquitlam Water Treatment Plant was excellent with no primary disinfection interruptions. Bacteriological water quality was excellent in the GVWD transmission mains and in‐system reservoirs with secondary disinfection stations boosting chlorine as required. No E. coli was detected and Disinfection By‐Products were below allowable concentrations. Both plants met or exceeded all Operating Permit criteria and water quality throughout the GVWD system met or exceeded the Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. The GVWD 2019 Water Quality Annual Report – Volume 1 is attached and provides a summary of the data collected. Detailed data can be found in Volume 2. PURPOSE To provide the GVWD Board with a summary of the 2019 GVWD Water Quality Annual Report. BACKGROUND Each year Metro Vancouver is required, under the Provincial Drinking Water Protection Regulation (DWPR), to produce an Annual Report on drinking water quality. The Annual Report is also a requirement of Metro Vancouver’s Drinking Water Management Plan. This information report, identified in the 2020 Water Committee Work Plan, is being brought forward at this time in order to enable Metro Vancouver, and its local government jurisdictions, to meet the reporting timeline stipulated in the DWPR. The Annual Report provides the key results and findings associated with Metro Vancouver’s program of continuous monitoring and assessment of drinking water quality in the region. It also provides an assessment of drinking water quality relative to the existing drinking water standards and guidelines and highlights any unusual occurrences. Monitoring results for local governments are also discussed where relevant.

2019 GVWD Water Quality Annual Report Water Committee Regular Meeting Date: April 30, 2020

Page 2 of 3

In accordance with Section 11 of the DWPR, the Annual Report will be sent to the Chief Medical Health Officers of the Vancouver Coastal and Fraser Health Authorities. Additionally, the Annual Report will be made accessible to the public through public libraries in the region, including Metro Vancouver’s library and Information Centre, and will be posted on Metro Vancouver’s website. WATER QUALITY/TREATMENT HIGHLIGHTS A summary of the main items relevant to water quality during 2019 follows. Source Water Quality i) In 2019, the turbidity levels of the delivered water met all the requirements of the Guidelines

for Canadian Drinking Water Quality (GCDWQ). ii) The Capilano supply was in service for the entire year. Heavy rainfall events in early January

resulted in Capilano source water turbidity peaking at 2.3 Nephelometric Turbidity Units (NTU). Even with the higher turbidity, the delivered filtered Capilano water was less than 0.1 NTU for the entire year.

iii) The Seymour supply was in service for the entire year. Heavy rainfall events both early and late in the year resulted in the Seymour source water turbidity peaking at 2.3 NTU. The delivered filtered Seymour water was less than 0.1 NTU for the entire year.

iv) The Coquitlam supply was in service for the entire year. The turbidity of the unfiltered Coquitlam source water was less than 1 NTU for the entire year.

v) The microbiological quality of the three source waters was excellent in 2019. All three sources met all the bacteriological requirements outlined in the GCDWQ.

vi) Results of the analyses of the source water for herbicides, pesticides, volatile organic compounds and radionuclides were all found to be below the recommended limits for these substances as listed in the GCDWQ.

Water Treatment i) The Seymour‐Capilano Twin Tunnels enabled the Capilano source water to be treated at the

Seymour‐Capilano Filtration Plant (SCFP) and subsequently returned to the Capilano transmission system throughout the entire year.

ii) The SCFP provided full filtration and the plant performance, as measured by the quality of the delivered water, was excellent in 2019. The daily average turbidity of water leaving the clearwells to enter the GVWD transmission system was 0.08 NTU.

iii) Turbidity levels for individual filters met the turbidity requirements of the GCDWQ. iv) Filtration consistently removed iron, colour and organics from Capilano and Seymour source

waters. v) Levels of total aluminum in filtered water were consistently below the GCDWQ operational

guideline value of 0.2 mg/L for direct filtration plants using aluminum‐based coagulants. The maximum value for 2019 was 0.03 mg/L.

vi) UV treatment is the primary disinfectant along with ozone pre‐treatment and chlorine disinfection for water originating from the Coquitlam source. Water treatment at the Coquitlam Water Treatment Plant met requirements as specified in the GVWD’s operating permit.

vii) The secondary disinfection stations within the distribution system operated effectively and boosted chlorine levels as required throughout 2019.

Distribution System Water Quality i) Bacteriological water quality in the GVWD transmission mains and in‐system storage reservoirs

was excellent in 2019. Of approximately 8,000 regional samples collected for testing in 2019, none were positive for E. coli.

ii) Bacteriological water quality in local government jurisdiction distribution systems was excellent in 2019. Of approximately 20,000 samples collected for testing in 2019, a high percentage (99.8%) were free of total coliforms, which was similar to 2018 (99.7%). In 2019, no E. coli was detected.

iii) The running average levels of the trihalomethane group of chlorine disinfection by‐products detected in the delivered water in the GVWD and local government jurisdiction systems were below the Maximum Acceptable Concentration (MAC) specified in the GCDWQ. The running average levels for the haloacetic acid group of chlorine disinfection by‐products in the GVWD system were below the Canadian Guideline MAC.

ALTERNATIVES This is an information report; no alternatives are presented. FINANCIAL IMPLICATIONS There are no financial implications. CONCLUSION As outlined by the 2019 GVWD Water Quality Annual Report, Metro Vancouver’s water quality monitoring program continues to fulfill its role in confirming that the multiple protection barriers for drinking water the GVWD has in place, including watershed protection, water treatment and ongoing operation of the water system to maintain water quality, are working effectively. Drinking water provided by the GVWD to its customers met or exceeded water quality standards and guidelines in 2019.

1. EXECUTIVE SUMMARY

Source Water Quality In 2019, the turbidity levels of the delivered water met the requirements of the Guidelines for

Canadian Drinking Water Quality (GCDWQ). The Capilano supply was in service for the entire year. Heavy rainfall events in early January resulted

in Capilano source water turbidity peaking at 2.3 Nephelometric Turbidity Unit (NTU). Even with the higher turbidity, the delivered filtered Capilano water was less than 0.1 NTU as measured by online instruments for the entire year.

The Seymour supply was in service for the entire year. Heavy rainfall events in September resulted in Seymour source water turbidity peaking at 2.3 Nephelometric Turbidity Unit (NTU). The delivered filtered Seymour water was less than 0.1 NTU as measured by online instruments for the entire year.

The Coquitlam supply was in service for the entire year. The unfiltered Coquitlam source water was less than 1 NTU for the entire year.

The microbiological quality of the three source waters was excellent in 2019. The levels of bacteria and protozoa detected were low and indicative of high quality source water. Coquitlam source water quality met the bacteriological requirements for avoiding filtration outlined in the turbidity section of the GCDWQ.

Results of the analyses of the source water for herbicides, pesticides, volatile organic compounds and radionuclides were all found to be below the recommended limits for these substances as listed in the GCDWQ.

Water Treatment

The Seymour Capilano Filtration Plant performance as measured by the quality of the delivered water, was excellent in 2019. The daily average turbidity of water leaving the clearwells to enter the GVWD transmission system was an average of 0.085 NTU in 2019.

Turbidity levels for Individual Filter Effluent (IFE) met the turbidity requirements of the GCDWQ. Filtration consistently removed iron, colour and organics from the Capilano and Seymour source

water. Levels of total aluminum in filtered water were consistently below the GCDWQ operational guideline

value of 0.2 mg/L for direct filtration plants using aluminum‐based coagulants. The maximum value for 2019 was 0.03 mg/L.

There were no outages of ultraviolet treatment at the Seymour Capilano Filtration Plant and the Coquitlam Water Treatment Plant.

The Seymour Capilano Filtration Plant and the Coquitlam Water Treatment Plant operated the full year using sodium hypochlorite for chlorination.

The secondary disinfection stations boosted chlorine when required.

Transmission/Distribution System Water Quality Bacteriological water quality was excellent in the GVWD transmission mains. No E. coli was detected. The detection of an E. coli triggers a protocol which involves immediate

notification of health and local government officials, re‐sampling, and a thorough investigation into the possible causes.

Bacteriological water quality was excellent in the GVWD in‐system storage reservoirs. There was no E. coli detected in any of the associated samples.

Bacteriological water quality was excellent in the distribution systems of the local governments. Of approximately 20,000 local government samples collected for testing in 2019 a high percentage

Water Committee

6

(99.8%) were free of total coliforms which was similar to 2018 (99.7%). No E. coli were detected in any of the samples taken in 2019.

The running average levels of the Trihalomethane group of chlorine disinfection by‐products detected in the delivered water in the GVWD and local government systems were well below the Maximum Acceptable Concentration (MAC) in the GCDWQ of 100µg/L (0.1 mg/L). The running average levels for the Haloacetic acid group of chlorine disinfection by‐products were below the GCDWQ MAC of 80µg/L (0.08 mg/L).

4. SOURCE WATER QUALITY

The first barrier in place to protect the quality of drinking water supply is the protection of the watershed to ensure the best quality source water. Source water monitoring provides ongoing confirmation that the barrier is effective, identifies seasonal changes and provides the monitoring information necessary to adjust the level of water treatment that is in place. Regular monitoring of the water sources is also a requirement of the Water

Quality Monitoring and Reporting Plan for Metro Vancouver (GVWD) and Local Government Members (WQMRP).

4.1 Bacteriological Quality of the Source Water The bacteriological quality of the source water is an important indicator of the degree of contamination, and the treatment required to ensure a safe water supply. The Drinking Water Treatment Objectives (Microbiological) for Surface Water Supplies in British Columbia section 4.3 states “The number of E. coli in raw water does not

exceed 20/100 mL (or if E. coli data are not available less than 100/100 mL of total coliform) in at least 90% of

the weekly samples from the previous six months. Treatment target for all water systems is to contain no

detectable E. coli or fecal coliform per 100 ml.” Table 1 below summarizes E. coli data for all three GVWD water sources. The levels of E. coli for all three sources were below the 10% limit in the provincial turbidity guideline.

Figure 1 shows the results of the analysis of the source water from 2015 to 2019 at all three intakes compared to the limits for source water bacterial levels in the Drinking Water Treatment Objectives (Microbiological) for Surface Water Supplies in British Columbia. As in previous years, all three sources easily met the limit of not more than 10% exceeding 20 E.coli /100mL. As was also the case in previous years, samples collected at the intakes in the fall and winter had the highest E.coli levels. These E.coli can be traced back to high flow levels at the main tributaries of the supply lakes and a first flush phenomenon after a period of dry weather.

Because of the protection of the watersheds from human sources of fecal waste, it is most likely that animals are the source of E. coli detected in the watersheds.

4.2 Source Water Monitoring for Giardia and Cryptosporidium Unfiltered surface water supplies have the potential of containing the protozoan pathogens Giardia and Cryptosporidium. Outbreaks of Giardiasis occurred in a number of locations in B.C. and Washington State in the late 1980s, and Metro Vancouver has been monitoring raw water for Giardia since 1987. Since 1992, Metro Vancouver has participated in a program with the Enhanced Water Testing Laboratory, to gather more information about the number and nature of cysts found in the Greater Vancouver water supplies. The program involves collecting samples from the Capilano and Coquitlam supplies upstream of disinfection. Routine monitoring of Seymour source water was discontinued in 2011 because water treatment at the SCFP meets the disinfection requirements for both Giardia and Cryptosporidium in the GCDWQ.

At the SCFP, monitoring for Giardia and Cryptosporidium has focused on the recycled water returning to the head of the plant and this monitoring has confirmed that the procedures in place effectively control the levels of Giardia and Cryptosporidium in the recycled wash water from the filters. The results of the 2019 testing program are contained in the “Report to Metro Vancouver – Giardia and Cryptosporidium Annual Report January – December, 2019” which was prepared by the BC Public Health Microbiology & Reference Laboratories, Environmental Microbiology, and can be found in Appendix 4. Four of 12 (33%) samples collected at Capilano and three of the 12 (25%) collected at Coquitlam were positive for Giardia (Table 2). As discussed previously, Seymour samples for 2019 are all process control samples and not Seymour source water, as they were prior to 2011 (shown as N/A in the table).

Year to year fluctuations are demonstrated for Giardia and Cryptosporidium and there has always been considerable variation in the results.

4.3 Turbidity GVWD water sources have been susceptible to turbidity upsets due to high runoff from storms which can cause slides and stream scouring in the watersheds or from re‐suspension of sediment from the edges of the lakes during periods of low water levels. The Drinking Water Treatment Objectives (Microbiological) for Surface Water Supplies in British Columbia allows a utility to exempt filtration if the turbidity does not exceed the requirements (see next paragraph) and provided that a number of other provisions including source water protection and two forms of water treatment requirements are in place. Historically the turbidity levels on both the Capilano and Seymour sources would not meet these criteria therefore plans were developed to filter both supplies. Filtration of 100% of the Seymour supply began in January 2010, and filtration and distribution of the Capilano supply through the Seymour transmission system commenced in February 2015. Both the raw and treated water tunnels were fully operational in April 2015. Section 4.4 of the Drinking Water Treatment Objectives (Microbiological) for Surface Water Supplies in British Columbia (Version 1.1, November 2012) contains the following provision for filtration exemption “For nonfiltered surface water to be acceptable as a drinking water source supply, average daily turbidity levels should

be established through sampling at equal intervals (at least every four hours) immediately before the disinfectant

is applied. Turbidity levels of around 1.0 NTU but not exceeding 5.0 NTU for more than two days in a 12‐month

period should be demonstrated in the absence of filtration. In addition, source water turbidity also should not

show evidence of harbouring microbiological contaminants in excess of the exemption criteria.”

Capilano and Seymour water is filtered so these source water criteria don’t apply to the delivered water. Coquitlam (unfiltered) was in service for all of 2019.

4.4 Chemistry

4.4.1 Chemical and Physical Characteristics of Source Water

The chemical and physical characteristics of the GVWD source water are summarized in Appendix 1 of this report; detailed analytical results are provided in Volume II. The results from the chemical and physical analyses of the source water in 2019 were similar to those for other years. 4.4.2 Herbicides, Pesticides, Volatile Organic Compounds, Radioactivity, and Uranium

Analyses of the source water for a variety of organic compounds including all of the compounds with Maximum Acceptable Concentrations (MACs) in the Guidelines for Canadian Drinking Water Quality is carried out on an annual basis in accordance with the WQMRP. The results are contained in Appendix 2 of this report and in Volume II of the Water Quality Annual Report. Uranium was the only parameter detected and it was below the applicable Canadian Guideline health based limits (MAC); these levels are indicative of erosion of natural deposits, meaning the contribution to total radiation exposure from our drinking water is small, and typical of most areas. 4.5 Limnology The Reservoir Water Quality Monitoring Program started in 2014 as a sampling and analysis structure for the limnology (chemical, physical and biological parameters) of the Capilano, Seymour and Coquitlam Reservoirs. Reservoir monitoring information is important in proactively managing our reservoirs as water quality could be impacted by environmental variability and climate change. This program assists in ensuring that variation and trends in reservoir quality are scientifically tracked over time.

Water sampling of the primary source reservoirs and inflow rivers is conducted between April and November each year. Biological productivity that can influence water quality is the highest during this time of year, making it an important time for sampling and measurements. Monthly sampling of the source water is conducted by staff and sample analysis is undertaken by accredited labs. High frequency water quality measurements are compiled by arrays of scientific instruments in each reservoir. The GVWD employs the services of a limnology consultant to review the annual program data, interpret physical, chemical, and biological conditions and examine long term trends. Results in 2019, as in previous years, confirmed the three reservoirs are ultra‐oligotrophic (see Appendix 3 for table), which means they have low levels of available nutrients and low levels of biological production. This ultra‐oligotrophic classification is highly desirable for source drinking water supply and shows that the GVWD watersheds and reservoirs continue to supply high quality water. Throughout North America there is interest in blue green algae (also known as cyanobacteria) in water reservoirs. These algae can produce toxins that are collectively known as microcystins. A common cyanobacterium in GVWD reservoirs is called Merismopedia spp., which is thought to produce these microcystins.

Despite the presence of cyanobacteria, the concentration of microcystins in GVWD reservoirs remains well below levels known to affect human health and are far below the Canadian Water Quality Guidelines. This desirable condition is due to the ultra‐oligotrophic status of the reservoirs (low nutrient availability to fuel algal growth). Algae blooms have not been observed in the source water supply reservoirs. Metro Vancouver continues to monitor cyanobacteria, including Merismopedia spp. as well as processes in the reservoirs that control the growth of cyanobacteria and other algae. This data is used to help predict changes to water quality over time related to climatic and environmental change and aid in making proactive decisions about ongoing reservoir management strategies.

5. QUALITY CONTROL ASSESSMENT OF WATER TREATMENT

Water treatment is the second barrier (after source water protection) relied on to assure the quality of the water supply. Completion of the Twin Tunnels Project in 2015 successfully concluded GVWD’s regional long‐range water treatment enhancement plans which spanned more than ten years. Each tunnel is 3.8 meters in diameter, 7.1 kilometers long, and 160 to 640 meters below ground level, running beneath Grouse Mountain and Mount Fromme. The water from the Raw Water Tunnel (RWT) is filtered and treated alongside the Seymour source water. Both treated sources enter the Clearwell for further treatment before the blended water is distributed to the region. Blended treated water returns to Capilano through the Treated Water Tunnel (TWT) and provides high quality drinking water to the Capilano area while the remainder is distributed through the Seymour system. In addition to the Twin Tunnels and the Seymour Capilano Filtration Plant (SCFP), other components of the Seymour Capilano Filtration Project include the Capilano Raw Water Pump Station (CRWPS), the Energy Recovery Facility (ERF), and the Capilano Break Head Tank (BHT), all adjacent to the Capilano Reservoir. The CRWPS houses 8 pumps used to pump Capilano source water through the RWT to the SCFP, which is at a higher elevation than the Capilano Reservoir. With the treated water returning through the TWT, excess pressure allows the ERF turbine to recover energy that partially offsets the power requirements of the CRWPS.

5.1 Seymour Capilano Filtration Plant The Seymour Capilano Filtration Plant (SCFP) is a chemically assisted direct filtration plant which uses poly aluminum chloride (PACl) as a coagulant with polymers to improve particle removal. These substances help aggregate particles to form visible floc. The flocculated particles are removed by passing this water through a filter medium of anthracite and sand. The result is the production of filtered water which is then exposed to ultraviolet (UV) light as the water leaves the filter. Post UV filtered water has sodium hypochlorite (chlorine) and lime added before the water enters the clearwells. The West and East Clearwells are large water storage reservoirs that store and allow controlled passage of water with some mixing or blending of the lime and chlorine that have been added. Clearwells allow sufficient retention or contact time with chlorine to provide any further disinfection required after filtration and UV. Carbon dioxide (CO2) in solution is added to trim pH. After stabilization of the filtered water in the clearwells, the finished water is ready to enter the transmission system at the Seymour Treated Water Valve Chamber. SCFP has been operational since December 2009 and the quality of the water produced has been excellent. 5.1.1 Filtration

As a result of treatment now in place on the Capilano and Seymour water sources there have been a number of changes in the characteristics of the delivered water. Some of these changes are visible, some not. The most obvious visible change in the water is the decrease in colour and increase in clarity. There is a total loss of brown hue that can sometimes characterize Capilano and Seymour waters before filtration. This change in colour is because the natural components that cause the brown hue are removed in the filtration process. Suspended particles in water that cause light to scatter (turbidity) are also removed. The end product is water that is very clear. Due to the purity of the water it may have a slight bluish colour. Figure 3 is a graph of the apparent colour of SCFP filtered water and Capilano and Seymour source waters for 2019. During the fall rainfall events the apparent colour of the Seymour source water feeding the filtration plant had a reading over 20 ACU. After the removal of the organic material through filtration, the colour of the filtered water delivered to the public was never greater than 3 ACU.

Water Committee

Figure 3: 2019 Apparent Colour Levels Before and After Filtration

Figure 4 compares turbidity of the two source waters that feed the filtration plant to the turbidity level of the finished filter water for 2019. Without filtration the Seymour source would have delivered water with an average daily turbidity greater than 1 NTU for 26 days. If the Capilano source had not been filtered and was delivered, in 2018, it would have exceeded 1 NTU on 36 days. Since both sources were filtered at SCFP, the maximum average daily turbidity of the delivered water was 0.1 NTU and the average was 0.085 NTU.

Figure 4: Average Daily Turbidity Levels Before and After Filtration 2019

Removal of turbidity in the source water improves the appearance of the water but it also has the benefit of removing certain types of pathogenic microorganisms that may be present in source water. At a minimum, properly run direct filtration plants such as SCFP will remove up to 2.5 log (one log is a 90% reduction) of Cryptosporidium and Giardia plus 1 log of viruses. To ensure this removal it is critical that the performance of each filter determined by the turbidity of its effluent is monitored on a continuous basis. The GCDWQ (2012) states: “For conventional and direct filtration, less than or equal to 0.3 nephelometric turbidity units (NTU) in at least 95% of measurements either per filter cycle or per month and never to exceed 1.0 NTU.” Ideally the turbidity from each individual filter would never exceed 0.1 NTU; however, there are rare occurrences of turbidity readings that exceed the ideal level. The turbidity performance of all twenty‐four filters is measured by examining the percent of time that the turbidity of each Individual Filter Effluent (IFE) met the turbidity guidelines of not greater than 1.0 NTU and at least 95% of time less than 0.3 NTU (Table 4). In 2019, there were no incidents where the IFE was greater than 1.0 NTU; and no incidences of filters turbidity readings that were greater than 0.3 NTU.

A water treatment facility such as SCFP should be able to produce a filter effluent that is less than 0.1 NTU. Under normal operating conditions the turbidity of the filtered water at SCFP is less than 0.08 NTU. All water that flows through the filters immediately passes through UV units. The intensity of the UV lamps automatically increases when there is an increase in turbidity of the water exiting the filter. After UV, the water is chlorinated as it enters the clearwell, where more than 1 hour of contact time is provided. 5.1.2 Ultraviolet Treatment

The effluent from each filter is treated with UV as the water exits the filter. UV treatment is effective in altering the DNA structure of Cryptosporidium and Giardia thus rendering oocysts and cysts of these parasites non‐infectious. Other disinfectants, especially chlorine are ineffective against Cryptosporidium oocysts. In the unlikely event of a breakthrough of Cryptosporidium oocysts, especially at the end of a filter run, UV light is present to render any potentially present parasites non‐infectious. Oocysts are not able to proliferate inside the intestines of human hosts to cause illness after a sufficient dose of UV light. The target dosage for UV to achieve 2 Log (99%) of Cryptosporidium and Giardia inactivation is 21mJ/cm2. Under normal operating conditions two rows of lamps operating at 75% power provide sufficient UV to meet the dosage requirement for 2 log reduction of Cryptosporidium and Giardia; with the remaining 1 log credit coming from the clearwell holding time for chlorination contact.

Table 5 summarizes the performance of the SCFP UV system in 2019.

5.2 Coquitlam Water Treatment Plant The Coquitlam Water Treatment Plant uses ozonation, soda ash, ultraviolet treatment and chlorination to treat water from the Coquitlam source. Ozonation provides pre‐treatment and helps remove micro‐organisms from the water, reduces disinfection by‐products and improves water clarity, which increases the efficiency of the subsequent UV process. Ozonation provides 4‐log virus inactivation. Soda ash is then added for pH and alkalinity adjustment for corrosion control. UV treatment (operational since 2014) provides for primary disinfection and aids in achieving 3‐log inactivation of chlorine‐resistant micro‐organisms, such as Cryptosporidium and Giardia. The water is directed into eight ultraviolet units, each containing 40 ultraviolet lamps encased in protective sleeves. UV light emitted from the lamps passes through the water. The US EPA requires that the UV disinfection process results in target Cryptosporidium and Giardia inactivation in at least 95% of the treated water volume on a monthly basis, which is summarized in Table 7. The US EPA standard is used because there is no Canadian standard. Chlorination is used for secondary disinfection at the source as well as at secondary disinfection stations to minimize bacterial regrowth in the distribution system. Chlorination provides 4‐log virus inactivation with liquid sodium hypochlorite since the compressed chlorine gas system was replaced in 2017. Table 6 summarizes the performance of the Coquitlam disinfection systems in 2019.

5.3 Secondary Disinfection There are eight secondary disinfection stations operated by Metro Vancouver. The purpose of these stations is to increase the chlorine residual in the water to meet a target residual based on a number of factors including source water turbidity, the amount of bacterial regrowth detected in the local government distribution system samples and the chlorine demand in the water. The rate of chlorine decay has been reduced within filtered water to a level that the amount of chlorine required to maintain a residual in the distribution system is significantly lower. The target chlorine dose leaving the secondary facilities receiving SCFP water is 0.8 mg/L. These facilities frequently have an incoming chlorine residual high enough that boosting is not required. Table 8 below summarizes the performance of the secondary disinfection facilities in 2019.

5.4 Corrosion Control Before 1998, the delivered water from all three sources had a pH lower than the aesthetic limit of the GCDWQ of pH 6.5 (the GCDWQ was changed in 2015 to 7.0 for pH). As part of the upgrade of the water treatment of the Seymour source water, a corrosion control facility using soda ash (sodium carbonate) was put into service at Rice Lake in 1998. A similar facility was added at Coquitlam in 2000 and remains in operation. In early 2010, corrosion control for the Seymour source was moved to the SCFP. In the SCFP process, filtered water receives a lime/water slurry to raise its pH and boost its alkalinity before it enters the clearwells; it is finally adjusted with the addition of CO2. The corrosion control facility at Rice Lake was decommissioned in 2010.

Water Committee

21

Since 2015, Capilano water is treated at the SCFP with lime and CO2 treatment processes for pH and alkalinity adjustment. The average pH of the treated water leaving Seymour Capilano and Coquitlam Water Treatment Plants was 7.6 and 7.7, respectively, during 2019 and met the aesthetic objective. The commissioning of the CO2 system at Coquitlam Water Treatment Plant (CWTP) began in 2019. When it is fully operational the CO2 system will allow the GVWD to meet target pH and alkalinity values. To achieve a higher alkalinity, the soda ash dose will be increased, which also raises pH. Therefore, the CO2 system is required to lower the pH back to the target value and to maintain its alkalinity target. The GVWD will be implementing moderate changes in pH and alkalinity in the coming years as part of our corrosion control program. Performance of the corrosion control facilities is summarized in Table 9. Table 9: Performance of Corrosion Control Facilities

6. TRANSMISSION/DISTRIBUTION SYSTEM WATER QUALITY

Schedule A of the BC Drinking Water Protection Regulation contains standards for the bacteriological quality of potable water in the province. There are three components of this standard that apply to large utilities such as GVWD and its members. Part 1: No sample should be positive for E. coli. Part 2: Not more than 10% of the samples in a 30‐day period should be positive for total coliform bacteria when more than 1 sample is collected. Part 3: No sample should contain more than 10 total coliform bacteria per 100 mL. The BC Regulation does not contain any water standards other than the three limits for E. coli and total coliform bacteria. Information on the significance of the detection of these organisms can be found in the Guidelines for Canadian Drinking Water Quality – Supporting Documents.

Water Committee

22

“E. coli is a member of the total coliform group of bacteria and is the only member that is found exclusively in the faeces of humans and other animals. Its presence in water indicates not only recent faecal contamination of the water but also the possible presence of intestinal disease‐causing bacteria, viruses and protozoa.” “The presence of total coliform bacteria in water in the distribution system (but not in water leaving the treatment plant) indicates that the distribution system may be vulnerable to contamination or may simply be experiencing bacterial regrowth.” To summarize, the detection of an E. coli bacteria in a sample of treated water is an indication of a potentially serious risk. The detection of total coliform bacteria may indicate intrusion into the system or it may indicate that these bacteria are growing in the distribution system itself (regrowth). The number of E. coli detected in both the GVWD and the local government drinking water samples is typically very low – out of more than 26,000 samples collected from the GVWD and local government systems, analyzed in 2019, no samples were positive for E. coli. The detection of an E. coli triggers a protocol which involves immediate notification of health and local government officials, re‐sampling, and a thorough investigation into the possible causes. Only 27 of the approximately 20,000 samples collected from the local government distribution systems tested positive for total coliforms in 2019. The majority of the coliforms in the local government system appeared in the warmer water months (75% in June through October) and at sites with a measurable free chlorine residual. The most likely source of these organisms can be attributed to bacterial regrowth. The one fact that should be emphasized is that 99.8% of the samples in 2019 had no coliforms present – a good indicator of effective water treatment and good distribution water quality. 6.1 Microbiological Water Quality in the GVWD System

6.1.1 GVWD Water Mains

Approximately 4,400 GVWD water main samples were collected and tested for the presence of indicator bacteria. The compliance of monitoring results from GVWD transmission mains with the criteria in the BC Drinking Water Protection Regulation is shown below in Figure 5. There were another 2,280 samples collected from stations where only chlorine residuals are measured as well as the 10‐minutes after chlorination sample line at each source but these samples are not included in the calculations for compliance monitoring.

Water Committee

23

Figure 5: Bacteriological Quality of Water in GVWD Mains, 2019

In 2019, the percentage of samples positive for total coliform bacteria from the GVWD mains was very low, well below the 10% standard. Of the approximately 4,400 samples processed, only 8 samples tested positive for total coliforms and no samples were positive for E. coli bacteria. 6.1.2 GVWD Reservoirs

In 2019, over 2,000 samples were collected from 21 reservoirs and tanks that are located throughout the GVWD water system. Only 1 sample was positive for total coliforms. No sample from a reservoir was positive for E. coli. The compliance of monitoring results from GVWD reservoirs with the criteria in the BC Drinking Water Protection Regulation is shown below in Figure 6.

Figure 6: Bacteriological Quality of Water in GVWD Reservoirs, 2019

Reservoir water quality is optimized by the use of secondary disinfection coupled with an active reservoir exercising program that includes a minimum of weekly monitoring of chlorine residuals and bacteriology results which can result in changes to filling levels if necessary. Table 10 provides an overview of the status of the GVWD reservoirs. During certain times of the year, it is not possible to cycle reservoirs as much as would be desired due to operational constraints. Despite these constraints, water quality as determined by coliform bacteria was satisfactory in all reservoirs. Table 10: Status of GVWD Reservoirs 2019

6.2 Microbiological Water Quality in Local Government Systems For samples collected from local government systems, the percent positive per month for total coliform bacteria from 2016‐2019 is shown in Figure 7. Figure 7: Percent of Samples per Month Positive for Total Coliform Bacteria 2016 to 2019

The percentage of samples positive for total coliform bacteria in 2019 remained relatively the same as compared to 2018. Schedule A of the BC Drinking Water Protection Regulation contains standards for the bacteriological quality of potable water in the province. There are three components of this standard that apply to local governments: Part 1: No sample should be positive for E. coli. Part 2: Not more than 10% of the samples in a 30‐day period should be positive for total coliform bacteria when more than 1 sample is collected. Part 3: No sample should contain more than 10 total coliform bacteria per 100 mL. For samples from local government systems, this requirement was met in 2019 with the following exceptions:

One sample in July contained more than 10 total coliform bacteria. One sample in December contained more than 10 total coliform bacteria.

Table 11 shows the compliance with the three bacteriological standards (parts) in the BC DWPR for samples taken within the distribution systems of the 20 local governments that are supplied with GVWD water.

6.3 Disinfection By‐Products in the Transmission/Distribution Systems As the treated water moves through the GVWD and into the local government infrastructure of pipes and reservoirs, changes in water quality occur mainly due to the reaction between the chlorine in the water (added during primary and secondary disinfection) and naturally occurring organic matter in the water. One of the most significant changes is the production of chlorinated disinfection by‐products (DBPs). DBP is a term used to describe a group of organic and inorganic compounds formed during water disinfection. Reactions between dissolved natural organic matter and chlorine can lead to the formation of a variety of halogenated DBPs. There are two major groups of chlorinated DBPs: The Total Trihalomethanes (TTHMs) and the Total Haloacetic Acids (THAA5). Factors that affect DBP formation are: amount of chlorine added to water, reaction time, concentration and characteristics of dissolved organic materials (precursors), water temperature, and water pH. In general, DBPs continue to form as long as chlorine and reactive DBP precursors are present in water. The maximum acceptable concentration (MAC) in the Guidelines for Canadian Drinking Water Quality (GCDWQ) for TTHMs is a locational yearly running average of 100 µg/L (0.1 mg/L) based on quarterly samples. Comparison of TTHM levels in the GVWD and local government systems in 2019 is shown in Figure 8. All TTHM results from GVWD mains and local government systems were below the MAC of 100 µg/L. The other group of disinfection by‐products of interest is the Total Haloacetic Acid (THAA5) group. The maximum acceptable concentration (MAC) in the GCDWQ for Total HAAs (THAA5) is a locational yearly running average of 80 µg/L (0.08 mg/L) based on quarterly samples. Comparison of THAA5 in the GVWD and local government systems in 2019 is shown in Figure 9. All THAA5 results from GVWD mains and local government systems were below the MAC of 80 µg/L.

7. QUALITY CONTROL/QUALITY ASSURANCE

In 1994, as required by a new Ministry of Health program, the Bacteriology Section of the GVWD laboratory received approval from the Provincial Medical Health Officer to perform bacteriological analysis of potable water as required in the B.C. Safe Drinking Water Regulation (changed to the BC Drinking Water Protection Regulation in 2001). An ongoing requirement of this approval is successful participation in the Clinical Microbiology Proficiency Testing (CMPT) program or its equivalent. Representatives of the Approval Committee for Bacteriology Laboratories will carry out an inspection of the GVWD laboratory facilities at Lake City Operations Centre in February 2019 as part of the process leading up to approval of the laboratory by the Provincial Health Officer. The next inspection is scheduled for 2022. In addition to the approval process discussed above, the GVWD Laboratory is accredited by the Canadian Association for Laboratory Accreditation (CALA) for the analysis of parameters for which the laboratory has requested certification. The GVWD Laboratory has been inspected by representatives from CALA bi‐annually since 1995. Accreditation for the laboratory from the Standards Council of Canada was first received early in 1996 and continued until the middle of 2005, when accreditation was granted by CALA directly. The most recent on‐site audit took place in November 2019, and CALA issued accreditation approval in February 2020. The next CALA inspection will take place in the fall of 2021.

Lucas Pitts, Acting Director, Policy, Planning and Analysis, Water Services Date: April 7, 2020 Meeting Date: April 30, 2020 Subject: Water Supply Forecast and Water Consumption Update for Summer 2020

RECOMMENDATION That the Water Committee receive for information the report dated April 7, 2020, titled “Water Supply Forecast and Water Consumption Update for Summer 2020”. EXECUTIVE SUMMARY This report summarizes the current state of source water supply and trends in water use and reflect current plans for operating the source reservoirs and water system this summer and fall. The existing snowpack, overall precipitation in the form of rainfall, and expected full source lake storage will be sufficient to ensure adequate water supply for the 2020 summer season. Peak day and winter water use continue to decrease while average day water use is starting to stabilize, indicating the importance of continued conservation initiatives. Recent system improvements have increased the capacity of the transmission system to meet peak summer demands. PURPOSE To provide the Committee and Board with the annual update on the current water supply and water consumption situation in advance of the approaching summer peak demand period. BACKGROUND As per the Committee’s 2020 Work Plan, and those of previous years, water supply and water consumption status reports are brought forward to the Committee and Board each spring. These reports are developed based on the current state of source water supply and trends in water use and reflect current plans for operating the source reservoirs and water system this summer and fall. CURRENT SOURCE WATER SUPPLY SITUATION Snowpack Snowpack measurements are routinely conducted at sample sites across the Capilano, Seymour and Coquitlam watersheds. The April 1, 2020 survey results indicate that the depth and water equivalent of the current snow pack are respectively 102 percent and 98 percent of the historical average for this time of year. These survey results indicate an average spring runoff from snowmelt. While snowpack is important, it should be noted that the region’s water supply is not solely dependent on snowpack. Overall precipitation in the form of rainfall contributes to the water levels in the three primary source reservoirs that serve Metro Vancouver.

Stored Water ‐ Source Reservoirs a) Capilano Reservoir: currently being managed under the spring operating protocol with the

reservoir currently at 91 percent of full summer storage capacity. It is expected that the lake will be at 100 percent of full summer storage capacity by early June.

b) Seymour Reservoir: currently being managed under the spring operating protocol with the reservoir currently at 80 percent of full summer storage capacity. It is expected that the lake will be at 100 percent of full summer storage capacity by early June.

c) Coquitlam Reservoir: controlled by B.C. Hydro within criteria established by agreement with the GVWD. It is expected that BC Hydro will have Coquitlam reservoir sufficiently full to provide for adequate regional summer water supply and the necessary allocation for fisheries flows in the Coquitlam River.

d) Alpine Lakes: GVWD’s three alpine lakes, Palisade, Burwell and Loch Lomond, which are used as reserves for Capilano and Seymour reservoirs during the summer period, are all expected to be at 100 percent of capacity by early summer.

Trends in Water Consumption/Use This section discusses trends in water consumption/use, as well as some of the factors affecting water use. Figure 1 shows water use in the region in litres per capita per day for the years 1994 to 2019.

Figure 1 – Peak Day, Average Day and Winter Day Per Capita Water Use in the Region

The upper (red) line in Figure 1 shows peak day water use over the 25‐year period. Historically, the peak day usage occurs on a hot and dry summer day when many people in the region are watering their lawns. The Drinking Water Conservation Plan (DWCP) includes annual implementation of

Water Committee


Page 3 of 4

Stage 1 restrictions on May 1 that limit lawn watering for residential and non‐residential properties to two mornings a week. In 2018, the Board endorsed Region‐wide Guide for Enforcement of Metro Vancouver’s Drinking Water Conservation Plan as a resource for member local governments. Key performance metrics on education and enforcement of the DWCP were first collected from member local governments in Summer 2018 and continue to be monitored. This information is helpful in moving the region toward more consistent best practices for enforcement of the DWCP regulations. The middle (black) line in Figure 1 also shows the average day per capita water use over the 25‐year period. This represents the overall regional water use on a per capita basis, which has been gradually trending downwards. In more recent years, there are indications that per capita water use is stabilizing, indicating the importance of continued water conservation initiatives. The lower (blue) line in Figure 1 shows winter per capita water use steadily declining between 1994 and 2019, in part due to recent water efficiency and conservation policies. During the winter months of November to March, outdoor water use is generally low with little fluctuation due to weather conditions, making winter water use on a per capita basis a good measure for comparing baseline water use from year to year. Metro Vancouver’s Drinking Water Management Plan (DWMP), first approved in 2005 and updated in 2011, includes water conservation actions for Metro Vancouver and member local governments. Work is currently underway to modernize and update the DWMP from its 2011 version. Figure 2 shows service population and total water use in billions of litres per day. Although total water use has stabilized in recent years, it is expected to increase as the effect of population growth on water demand begins to exceed per capita water use reductions due to water efficiency.

Figure 2 – Population Growth and Daily Water Use

SYSTEM OPERATIONS OUTLOOK FOR SUMMER 2020 Water usage patterns will be monitored and adjustments made to withdrawals from each of the three main sources and within the transmission system to meet the regional water demand through the summer and fall. Additional withdrawals from Coquitlam Reservoir have been secured from BC Hydro for 2020. The three alpine lakes will also be utilized within their refillable storage limits, as required. Hot and dry summer weather conditions drive peak day and peak hour demands and may create challenges for the transmission system to meet service levels in parts of the region, most notably in the southern and eastern parts that are both geographically furthest from the sources and are experiencing the fastest population growth rates. Recent system upgrades including Clayton Reservoir, Barnston Maple Ridge Pump Station, South Delta Main No. 1 Replacement (Phases 1 and 2), and the Port Mann Water Supply Tunnel have all contributed to additional transmission system capacity to meet summer peak demands in both the eastern and southern municipalities and will benefit the regional transmission system in summer 2020. ALTERNATIVES This is an information report; no alternatives are presented. FINANCIAL IMPLICATIONS During the hotter and drier months, the demand for water increases significantly over that in the winter, putting additional stress on the water supply system. Metro Vancouver’s wholesale peak summer water rate is 25 percent higher compared to the off‐peak period. This seasonal pricing reflects the cost of building larger infrastructure and higher operating costs such as increased pumping to meet peak summer demands. Metro Vancouver is currently monitoring water consumption on a daily basis to identify any impacts that may arise from the COVID‐19 pandemic. CONCLUSION The existing snowpack, overall precipitation in the form of rainfall, and expected full source storage will be sufficient to ensure adequate water supply for the 2020 summer season. Although the region’s population continues to grow; historically, overall water demand has remained relatively steady, generally offset by conservation measures. However, overall water use is increasing gradually as the effect of the rate of population growth on water demands begins to exceed the per capita water use reductions. Outdoor watering regulations, along with member local government’s implementation of the Region‐wide Guide for Enforcement of the DWCP, are expected to help manage water demands during the upcoming peak season. Recent system improvements such as the Barnston/Maple Ridge Pump Station, the Port Mann Water Supply Tunnel, Clayton Reservoir, and South Delta Main No. 1 Replacement (Phases 1 and 2) have increased the capacity of the transmission system to meet peak summer demands. 37242029

Water Services Date: April 17, 2020 Meeting Date: April 30, 2020 Subject: Water Services Capital Program Expenditure Update to December 31, 2019

RECOMMENDATION That the Water Committee receive for information the report dated April 17, 2020, titled “Water Services Capital Program Expenditure Update to December 31, 2019”. EXECUTIVE SUMMARY The capital expenditure reporting process as approved by the Board provides for regular status reports on capital expenditures 3 times per year. This is the year‐end report for 2019 which includes both the overall capital program for Water Services with a multi‐year view of capital projects and the actual capital spending for the 2019 fiscal year in comparison to the annual budget. In 2019, annual capital expenditures for Water Services were $243.5 million compared to a capital budget of $231.4 million. This timing difference has been funded through the application of accumulated surplus from capital underspends from prior years. Forecasted expenditures for the current Water Services capital program remain within the approved budgets through to completion. PURPOSE To report on the status of the Water Services capital program and financial performance for the year ending December 31, 2019. BACKGROUND The capital expenditure reporting process as approved by the Board provides for regular status reports on capital expenditures with interim reports sent to the Water, Liquid Waste, Zero Waste, and Performance and Audit Committees, in June/July and October/November, and a final year‐end report to the Committees and the Boards in April of each year. This is the third in a series of three reports for 2019 and looks at both the overall capital program for Water Services with a multi‐year view of capital projects and the actual capital spending for the 2019 fiscal year in comparison to the annual budget. 2019 CAPITAL EXPENDITURES Capital Program Funding The capital spending for Water Services is funded through the Water Operating Budget by a combination of contribution to capital (pay‐as‐you‐go funding) and debt service costs (principal and interest payments).

As a result, the annual impact on the ratepayers is significantly less than the level of budgeted capital expenditures. Overall Capital Program The overall capital program for Water Services includes capital projects which require multiple years to complete. These projects are broken down into various phases such as project definition, pre‐design, detailed design and construction. With the completion of each phase, more information is learned for the appropriate costing of subsequent phases. It is expected that the capital spending on all Water Services capital projects completed in 2019 or ongoing at some point in 2019 will be under budget by approximately $8.8 million, this is within 0.1% of budget. Table 1 in Attachment 1 provides a summary of GVWD capital expenditures for both ongoing and completed projects. Completed Projects include a summary of actual spending compared to the Board approved spending limits while the Ongoing Projects include a summary of projected spending to completion compared to Board approved spending limits. With the rare exception, projects tend to complete with actual spending below the approved limits predominantly due to savings on budgeted contingency amounts. Attachment 2 provides the details behind the summary information including specific capital projects, summary financial information and notes where required. Attachment 3 provides additional project status information for some of the key projects included in Attachment 1 – Table 1. 2019 Capital Program Progress The Metro Vancouver financial planning process includes Board approval of both an annual Operating Budget (operations, contribution to capital and debt service) and an annual Capital Budget for the planned capital infrastructure projects. The annual Capital Budget comprises the projected spending for a list of capital projects either continuing or to be started within the calendar year. In 2019, capital expenditures for Water Services were $243.5 million compared to a total capital budget of $231.4 million. The main driver for this was several large capital projects in the construction phase proceeding faster than anticipated. This timing difference has been funded through the application of accumulated surplus from capital underspends from prior years. Forecasted expenditures for the current Water Services capital program remain within the approved budgets through to completion. Table 2 in Attachment 1 provides a summary of the 2019 actual capital spending compared to the Board approved Capital Budget. ALTERNATIVES This is an information report.

twice per year to long term debt through the Municipal Finance Authority. Any capital spending overages will be funded through the application of accumulated surplus generated from capital underspending in prior years. The Water Services capital fund has approximately $34.2 million remaining in accumulated surplus that will be applied to 2020 capital expenditures for Water Services. CONCLUSION This is the third in a series of three reports on capital expenditures for 2019. Water Services is projecting to be under budget for capital projects ongoing or completed in 2019. In 2019, actual capital expenditures exceeded that budgeted by $12.1 million due to some large capital projects proceeding faster in the construction phase than anticipated. This timing difference has been funded through the application of accumulated surplus from capital underspends from prior years. Forecasted expenditures for the current Water Services capital program remain within the approved budgets through to completion. Attachments 1.

Campaign

RECOMMENDATION That the Water Committee receive for information the report dated April 1, 2020, titled “2020 Watering Regulations Communications and Regional Water Conservation Campaign”.

EXECUTIVE SUMMARY Metro Vancouver undertakes several communications initiatives to ensure water resources are conserved and efficiently used throughout the region. Key initiatives in 2020 include communication of the region-wide watering regulations and a regional communications campaign – the We Love Water campaign – to increase awareness of Metro Vancouver’s water system and the need for residential water conservation. Metro Vancouver will communicate the May 1 watering regulations activation date via advertising and social media engagement across the region, and through a range of promotions and items distributed to Members for public education and enforcement throughout the irrigation season. The We Love Water campaign will emphasize water system awareness beginning May 19, before incorporating outdoor water conservation information from July 2 until September 6. A targeted media buy will include both television, radio, outdoor and digital promotions, all leading to the welovewater.ca website. PURPOSE To update the Committee on regional communications to support the 2020 watering regulations and the regional water conservation campaign. BACKGROUND Metro Vancouver undertakes several communications initiatives to ensure water resources are conserved and efficiently used throughout the region. Communication of the region-wide watering regulations supports the Drinking Water Conservation Plan, which helps manage the use of drinking water during periods of high demand and largely impacts the watering of lawns and landscapes. A regional communications campaign – the We Love Water campaign – now in its fifth year, increases awareness of Metro Vancouver’s water system and the need for residential water conservation, while providing residents with tips for using less water around their homes. This report provides an update on communications around the 2020 watering regulations and the 2020 regional water conservation campaign as identified in the 2020 Water Committee Work Plan.

WATER CONSERVATION COMMUNICATIONS 2020 Watering Regulations Communications Metro Vancouver collaborates with Members to determine the most effective messaging and methods for consistently communicating the regional watering regulations contained within the Drinking Water Conservation Plan to residents and businesses. As a result, Metro Vancouver will undertake the following activities to create awareness:

Develop and distribute communications materials to support Members’ education and enforcement programs, including translated materials;

Notify public of regulations via newspaper advertising prior to the May 1 activation date;

Distribute information on the regulations via mailed communications material to residents, targeted towards single-family homes most likely to have lawns;

Advertise via targeted social media, in advance and during activation dates; and

Issue a media release and conduct interviews. Communications will direct residents to Metro Vancouver’s lawn watering regulations webpage. This page also features water-efficient lawn care and gardening content, including linkages to Metro Vancouver’s Grow Green Guide, as well as a simplified scheduler to help determine whether different watering activities are allowed on a given day. Examples of communications materials to support the regional watering regulations are included in Attachment 1. Regional Water Conservation Campaign Communications The regional ‘We Love Water’ conservation campaign encourages mindful and responsible use of drinking water, and increased awareness and pride for Metro Vancouver’s water system. The campaign will be sequenced to emphasize water system awareness beginning May 19, before incorporating outdoor water conservation information from July 2 until September 6. By teaching residents about where their drinking water comes from, and the amount of work it takes to reach their taps, they will better understand the importance of using less water around their homes. Information about Metro Vancouver’s water system will be targeted towards a broader regional audience, while outdoor conservation topics will be directed towards detached home owners with lawns, who are most likely to be engaged in significant outdoor water use. Campaign components in 2020 to generate awareness and encourage conservation will include the following:

Television broadcast partnership with Global BC, featuring commercials and segments endorsed by media personalities, as well as branded online content;

Commercials on additional television networks;

Radio broadcast partnership featuring dry weather alerts from media personalities;

Digital billboards on major routes throughout Metro Vancouver (note that this expenditure may be shifted to supplement other campaign promotions if commuting levels remain low throughout summer due to COVID-19 response);

Targeted social media advertising; and

Online banner, YouTube video, and search engine advertising targeting users’ interests (e.g., gardening, lawns, car washing) to encourage conservation, as well as weather forecast-activated advertising.

The 2020 campaign will build upon the creative concept established in previous years, with a unified ‘pipe’ theme linking features of the water system with conservation messaging. The campaign’s emphasis on the people and roles involved in providing clean, safe drinking water will increase; Metro Vancouver staff will be featured prominently in promotions, to share the level of care and responsibility they provide to the different stages of the process, from the mountain watersheds to delivering water to residents. By putting a relatable, human face on the water system, the campaign will help residents understand why they should also care about their drinking water, attach value to it, and not waste it. Draft examples of communications concepts to support the regional conservation campaign are included in Attachment 2. All materials lead to the welovewater.ca campaign website, for conservation tips and information about Metro Vancouver’s water sources and system. All materials will be shared with Members for display and distribution through localized opportunities. ALTERNATIVES This is an information report. No alternatives are presented. FINANCIAL IMPLICATIONS The 2020 watering regulations communications and regional water conservation campaign have a total budget of $270,000. These costs are included in the 2020 Water Services Communications Program Budget managed by External Relations. CONCLUSION Metro Vancouver will communicate the May 1 watering regulations activation date via advertising and social media engagement across the region, and through a range of promotions and items distributed to Members for public education and enforcement throughout the irrigation season. The ‘We Love Water’ regional water conservation campaign will begin May 19, with a mix of television, radio, outdoor, and digital advertising, and will emphasize water resource education before incorporating conservation messaging in the warmer and drier summer months. Creative materials and collateral will be shared with members so they can support the campaign through their own communications channels.

Subject: Award of Phase C ‐ Construction Engineering Services for the Annacis Water Supply Tunnel

RECOMMENDATION That the GVWD Board: a) approve the award of Phase C, Construction Engineering Services in the amount up to $17,881,271

(exclusive of taxes) to the Phase A and B project consultant, Hatch Corporation, for the Annacis Water Supply Tunnel (Request for Proposal No. 15‐127); and

b) authorize the Commissioner and the Corporate Officer to execute the required documentation.____________________________________________________________________________________

EXECUTIVE SUMMARY In 2015, GVWD issued Request for Proposal (RFP) No. 15‐127: Consulting Engineering Services for Preliminary Design, Detailed Design and Construction Engineering Services for the Annacis Water Supply Tunnel. A contract for Phase A, Preliminary Design, was subsequently awarded to Hatch Corporation (Hatch). In 2017, the GVWD Board approved the award of Phase B, Detailed Design, to Hatch. With the project nearing the completion of Phase B, Hatch provided an updated fee estimate for Phase C, Construction Engineering. The total amount for Phase C increased compared to the original proposal, primarily due to contractually allowed hourly rate increases for inflation since 2015, as well as an increase in the construction schedule, and an allowance for quality assurance testing. Based on the evaluation, it is recommended that the GVWD Board award Phase C Construction Engineering Services to Hatch Corporation, in the amount up to $17,881,271 (exclusive of taxes), and authorize the Commissioner and the Corporate Officer to execute required documentation.

PURPOSE The purpose of this report is to request authorization by the GVWD Board to award Phase C, Construction Engineering Services to the Phase A and B project consultant, Hatch Corporation, for the Annacis Water Supply Tunnel in the amount of up to $17,881,271 (exclusive of taxes).

BACKGROUND Pursuant to the GVWD Officers and Delegation Bylaw No. 247, 2014 (Bylaw) and the Procurement and Real Property Contracting Authority Policy (Policy), procurement contracts which exceed a value of $5 million require the approval of the GVWD Board of Directors. Further, the Policy states that contracting authority for multi‐phase contracts is determined based on the anticipated total value of the services to be provided over all phases.

The original contract for Phase A, Preliminary Design engineering services, was awarded to Hatch in 2015. Upon the successful completion of preliminary design, at its meeting on June 30, 2017, the GVWD Board approved the award of Phase B, Detailed Design engineering services, to Hatch. Staff now require GVWD Board approval to proceed with Phase C, Construction Engineering Services. This report is being brought forward to the Water Committee to consider a recommendation to the GVWD Board to authorize award of Phase C ‐ Construction Engineering Services, to the Phase A and B project consultant, Hatch Corporation, in order to continue with engineering services through construction of the Annacis Water Supply Tunnel. PROJECT DESCRIPTION The Annacis Water Supply Tunnel project will provide increased capacity to meet future demand south of the Fraser River, long term scour protection, and improved resiliency to withstand a major earthquake. The location of the project is shown on Attachment 1. The project comprises an approximately 2.3‐kilometer‐long tunnel and two deep vertical shafts, one in the City of New Westminster and one in the City of Surrey. The project will include:

constructing temporary access shafts; excavating a deep tunnel below the river using a Tunnel Boring Machine (TBM); installing a large diameter steel water main inside the tunnel and shafts; constructing underground valve chambers near the top of each shaft; and connecting the water supply tunnel to new water mains on each side of the river.

A Request for Qualification (RFQ) No. 15‐049 for the preliminary design, detailed design, and construction engineering of the Annacis Water Supply Tunnel was publicly advertised on Metro Vancouver’s and BC Bid websites on March 4, 2015. A Request for Proposal (RFP) No. 15‐127 was subsequently issued on August 6, 2015 to the two proponents shortlisted during the RFQ process. The RFP closed on September 18, 2015, and both proponents submitted proposals. Hatch was identified as offering the highest‐ranked proposal. Following negotiations, Hatch was awarded Phase A, Preliminary Design, for $5,386,942. At the time of award of Phase A, the anticipated value of the contract for all three phases of work was $30,600,994 (exclusive of taxes). On May 11, 2017, following the completion of Phase A, Hatch provided an estimated cost for Phase B, Detailed Design, totaling $11,108,137 (exclusive of taxes). The GVWD Board subsequently approved the award for Phase B at its meeting on June 30, 2017. Phase B is now substantially complete. On February 5, 2020, following discussions and negotiations with staff, Hatch submitted a revised estimated cost for Phase C, Construction Engineering Services, totaling $17,881,271 (exclusive of taxes). The amount is higher than the original proposed amount of $14,861,997 (exclusive of taxes) primarily due to contractually allowed staff hourly rate increases for inflation since 2015, an increase in the construction schedule, and an allowance for quality assurance testing which was not included in the original RFP. The increase in the cost for Phase C was reviewed by Water Services and Purchasing staff and is deemed reasonable.

Page 3 of 3 ALTERNATIVES 1. That the GVWD Board:

a) approve the award of Phase C, Construction Engineering Services, in the amount up to $17,881,271 (exclusive of taxes) to the Phase A and B project consultant, Hatch Corporation, for the Annacis Water Supply Tunnel (Request for Proposal No. 15‐127); and

b) authorize the Commissioner and the Corporate Officer to execute the required documentation.

2. That the GVWD Board terminate the contract with Hatch Corporation resulting from RFP No. 15‐127: Consulting Engineering Services for Preliminary Design, Detailed Design and Construction Engineering Services for the Annacis Water Supply Tunnel and direct staff to report back to the GVWD Board with options for an alternate course of action.

FINANCIAL IMPLICATIONS If the GVWD Board approves Alternative 1, Construction Engineering Services, in the amount up to $17,881,271 (exclusive of taxes), will be added to the contract with Hatch Corporation. This amount is within the total construction budget allotted for the project. The GVWD Board has the choice not to proceed with Alternative 1, but staff will need further direction in relation to the project. Alternative 2 will likely result in a delay to the project schedule which could add additional costs to the overall project. CONCLUSION Request for Proposal No. 15‐127 was issued for Preliminary Design, Detailed Design and Construction Engineering services for the Annacis Water Supply Tunnel. The contract for Phase A, Preliminary Design, was awarded on December 11, 2015 to Hatch Corporation. Hatch’s contract was subsequently amended to include Phase B, Detailed Design engineering services. As Phase B nears completion, staff have identified that the total anticipated value of the contract for Phase C, Construction Engineering Services, will exceed the original estimated cost of $14,861,997 (exclusive of taxes). This is primarily the result of hourly rate increases due to inflation which are allowed in the contract, an increase in the construction schedule, and an allowance for quality assurance testing during construction which is required but was not included in the original RFP. Based on the evaluation of the revised scope and costs, it is recommended that the GVWD Board authorize the award of Phase C ‐ Construction Engineering Services to Hatch Corporation in the amount up to $17,881,271 (exclusive of taxes), and authorize the Commissioner and Corporate Officer to execute the required documentation. There is sufficient funding within the overall project budget to support the contract increase. Attachment Annacis Water Supply Tunnel ‐ Location Plan 3699826

RECOMMENDATION That the Water Committee receive for information the report dated April 17, 2020 titled “Manager’s Report”.

1. Nicomekl Sea Dam

The City of Surrey has applied for and received federal funding under the Disaster Mitigation and Adaptation Fund (DMAF) to complete a suite of projects associated with climate change throughout the municipality. Replacement of the 100‐year old Nicomekl Sea Dam is a key project being undertaken to ensure the continued protection of the low‐lying upstream area from flooding and salinity intrusion. Metro Vancouver’s South Surrey Main (760 mm) runs inside the dam to cross the Nicomekl River. Metro Vancouver provided Surrey with a letter of support for the project and committed to contribute funds to replace and upgrade the section of main within the dam. Metro Vancouver’s long‐term plan is to replace and upsize the South Surrey Main #1 with the South Surrey Main #2 to meet the growing area demands. Replacing the section through the dam will be the first phase of the project. With the Disaster Mitigation funding now in place, Water Services staff have started to work on a coordinated work agreement with Surrey called the Ultimate Recipient Agreement. This agreement will come back through the Committee and Board for approval in the next few months. Work on the dam replacement is expected to begin over the winter of 2020/2021. The next phase of South Surrey Main #2 construction is planned to commence in 2029. 2. Snowpack Monitoring & Upgrade Project Water Services, conducts snowpack monitoring from December – June of each year as it relates to water supply storage. Snowpack sampling sites are located throughout the three primary water supply areas (Capilano, Seymour & Coquitlam) where measurements are repeated at consistent locations to relate current conditions to the historical dataset. One of the snowpack sampling locations is among the oldest in the province with a dataset extending back to the 1930s. The weight of the snow and depth of the snowpack is analyzed to determine how much water is stored in the snowpack and will be available for water supply as the snow melts through the spring and into the early summer. This information is utilized for water supply planning and also contributes to the Provincial flood risk datasets. Snowpack Monitoring Upgrade SIF Project: Water Services is currently completing a SIF Project aimed at enhancing and modernizing the snowpack monitoring program. The technology and program upgrades will improve Metro Vancouver’s watershed hydrological models and water supply forecasts, allowing more effective

adaptation to climate change and management of water supply in a sustainable and progressive manner.

This project has the following objectives: to modernize the watershed snowpack monitoring program by testing emerging technology and

processes; create more accurate snow water equivalent maps for water supply planning, research, climate

change monitoring, and education; and reduce the reliance on manual observations over time, which will result in a safer and more cost‐

effective snow monitoring program. Upgrades associated with this project have allowed technologists to respond to work restraints from the COVID‐19 Pandemic including restriction on helicopter travel for on‐site snow surveys. Technology process improvements tested over the first four months of the snow season have shown promising results and excellent comparison (+/‐ 5%) to field collected data. The data presented in the April 1 snow survey is generated using the new technology in combination with automated snowpack data from remote weather stations. On April 1, there was approximately 20% more snow than this time last year due to cool and wet conditions at the end of March that added a significant amount of snow. 3. First Narrows Tunnel Isolation Improvements (North Shaft)

The First Narrows Tunnel Isolation Improvements (North Shaft) project is located in the District of North Vancouver immediately adjacent to the north foreshore of the First Narrows crossing, and consists of replacing three existing 1200 mm diameter valves and installing one additional 900 mm diameter valve. The existing valves were installed in 1937 and 1969 and have been subjected to a corrosive marine environment given their close proximity to the ocean. The deteriorated condition of the valves meant they needed to be replaced to ensure reliable operation and control of drinking water in the transmission system. The refurbishment work started with an operational test to close the valves on either side of the crossing. Although the operational test successfully confirmed that the regional and local water systems could meet water demands with the First Narrows tunnel closed, it also identified one additional large diameter valve that needed to be replaced as it was in worse condition than anticipated from earlier inspections. This important system refurbishment work is scheduled to recommence in mid‐November 2020 and is expected to be complete by April 2021. This project is an example of the complexity of completing refurbishment projects to address the aging infrastructure in parts of the regional transmission system. 4.
