Billings Integrated Water Plan Chartering Workshop
May 27, 2010
Key Questions• What is Integrated Water Planning?• Why are we doing Integrated Water
Planning?• How is it different from conventional
planning?• What are the benefits and outcomes
of the Process?• Where are we in the process?• How can you participate?
This is not just another planning document. This represents the
beginning of a fundamental transition of how we manage our water resources in the
Billings area.
What is Integrated Water Planning?
• An approach that balances competing water uses and considers cost effectiveness, environmental, and social values.
Many communities in the South and West have done Integrated Water Planning to balance competing water resource needs.
Why are we doing Integrated Water Planning?
Because it’s all connected…
The City’s wastewater pipe network drains to a central treatment facility that discharges to the Yellowstone River.
Wastewater Challenge
• New river discharge restrictions will require costly improvements
The area of growth is away from the central plant site
Wastewater Management Approaches
Conventional• Total Maximum Daily Load
(TMDL)– Lower Effluent Limits
• NPDES Discharge Permit Renewal
• Capitalize Advanced Treatment Technology– Add Nutrient Removal
• Potential Issues– Expense– Requirements Beyond Limits of
Technology
Integrated Water Plan• Effluent Management
– Reclaimed Water Reuse• Urban Irrigation• Industrial• Other
– Aquifer Recharge– Wetlands Restoration
• Water Quality Offsets and Trading
• Would still require other capital improvements (distribution and/or treatment)
Options to Meet Restrictive TMDLs
Water Reclamation
Facility
Urban Irrigation•Parks, Schools, Fairgrounds
Industrial Reuse•Paper Mill, Rock Crushing, Concrete
Wetlands Restoration•Creation, Restoration, Enhancement
Groundwater Recharge• Surface PercolationO

Urban Irrigation
Washington State Capitol Grounds(Olympia, Washington)
Sunken Garden(Olympia, Washington)
Industrial Reuse
Recycled water from the West Basin Recycling Facility in El Segundo; CA is provided to industrial customers
for non-potable uses.
Groundwater Recharge
Riparian Preserve (Gilbert Arizona)
LOTT Hawks Prairie (Lacey, Washington)
Sidestream Nutrient Recovery
• Phosphorus Removal Applications– Anaerobic Digestion– Dewatering
• Struvite (MAP) Reactor– Recycles Nutrients as Fertilizer– Reduces Solids Stream Recycle
Impact– Reduces Chemical Use– Potential Greenhouse Gas
Credit • ~6 to 8 tons CO2 Equivalent per
Ton of Struvite

The City’s central WTP distributes water through its pipe and reservoir network.
Water
Peak day summertime demands drive drinking water treatment capacity decisions.
Irrigation Demand
Drinking Water• Current approach recommends a new West End
WTP at an approximate cost of $60-90M• Summertime irrigation demands drive the need for
that facility• Water rights are in limbo• Best use of resource for all uses (cooling water,
irrigation, etc.) ?
The City’s central WTP is nearing its capacity.
Drinking Water Management Approaches
Conventional• Driver
– New Plant Capacity Needed– Water Rights– SDWA Compliance– Limitations of Existing Distribution
Infrastructure• New West End Plant• Off Stream Storage• Potential Issues
– Expense– Additional Staff
Integrated Water Plan• Alternatives to Treated Water
for Irrigation– Irrigation Canal– Reuse Water
• Use Aquifer for Storage• Conservation• Off Stream Storage• Will require construction of
capital facilities
Irrigation out of canals could save peak treatment capacity

All Parcels within LOA Boundary
Irrigation Potential by Water Demand (MGD)
Adjacent to Irrigation SupplyWithin 500' of Irrigation Supply
Would require additional distribution piping
The City’s stormwater pipe network discharges to the Yellowstone River in several locations.
Stormwater• New water quality benchmarks for stormwater
discharges are in place• Monitoring today indicates some water quality
improvements will be needed• The Current Master Plan includes >$40M in high
priority improvements to address flooding issues
Future developments will include provisions to limit runoff to prevent future flooding problems.
We are unique in having a large irrigation system running through the urban area.
Irrigation• Established canal system throughout the service
area• Faces a declining customer base• Funding challenges• Infrastructure improvements are needed to maintain
old facilities
Irrigation will be a critical component to Integrated Water Planning.
Stormwater Management Approaches
Conventional• Stormwater NPDES Discharge
Permits– 6 Minimum Control Measures– Best Management Practices
(BMPs)• Total Maximum Daily Load
(TMDL)– Wasteload Allocations
• Historically Quantity-based• Increasing Regulatory
Emphasis on Water Quality– Add Water Quality BMPs
Integrated Water Plan• Infiltration/Inflow
– Stormwater May Drive Peak Wastewater Flows
• Effluent Management– Links with Canals and Drainage
Systems• Water Quality Offsets and
Trading– Stormwater Reductions to Off-set
Wastewater Discharges
Potential for TMDLs to Drive WasteloadAllocations for Regulated Stormwater
Water Quality Best Management Practices

• All-Natural System• Provides Nutrient Uptake• Small Footprint

Opportunities for Collaboration?
West Basin Municipal Water District, El Segundo, CA• Five different qualities of “designer”
or custom-made recycled water 1. Tertiary Water2. Nitrified Water3. Softened Reverse Osmosis Water
Secondary treated wastewater pretreated by either lime clarification or microfiltration, followed by reverse osmosis (RO) and disinfection for ground-water recharge
4. Pure Reverse Osmosis Water5. Ultra-Pure Reverse Osmosis Water
• Injected into South Bay’s groundwater basin to prevent seawater intrusion
Advanced Oxidation Process (AOP) –Peroxide and UV
Why are we doing Integrated Water Planning?• Wastewater-Restrictive limits for continued discharge
to the Yellowstone River• Drinking Water—
– Peak irrigation demands lead to new WTP– Water Rights– Best use of resource?
• Stormwater—New permit limits for discharge from MDEQ
• Irrigation—Declining customer base and increasing management costs
• May be opportunities to collaborate
What are the benefits of an Integrated Water Plan?
• Allows time to make incremental changes• Long term cost effective service• Allows time to explore opportunities for more efficient
uses of water resources• Identify Opportunities
What are the outcomes of the Integrated Water Plan?
• Clear definition of problems, goals and objectives• Establish Community Values• Define and evaluate alternative strategies
– Projects/Capital Facilities– Programs and Policies-Nonstructural Management
Measures• Implementation Plan
– Prioritized Actions– Defined Funding– Long Term Management Program
• Adopted plan will serve as a road map for the future
How will we prepare the Integrated Water Plan?
• No preconceived notions about the outcome• No Cookie Cutter Approach• Facilitated Process• Broad stakeholder participation
– Build strong working relationships– Inclusive to build awareness and support
• Coordinate water management

Opportunities for consideration
• Discharge Effluent to a different location-groundwater, irrigation canal, wetland, etc.
• Move to Satellite treatment plants for water and wastewater
• Use Irrigation Canal for lawn irrigation• Use Reuse water for lawn irrigation• Store Finished Water Underground (ASR)• Change Development policies to minimize
stormwater runoff and improve runoff quality (Already required)
Other Ideas?
Next Steps-Where are we going?
• Establish Work Group participation• Define additional projects, policies, technologies to
be considered• Screen and Prioritize Alternatives• Design of Implementation Plan• Produce the IWP by the end of the year
How can you participate?
