Water Source / Supply Study Workshop #1 Joint Shared Service Committee May 18th
Presentation Overview Water Water Supply Water Next System Demand Source Conservation Steps Choices Review Planning Needs Conservation Policy • Sources and Infrastructure • Options Water Issues • Supply Needs to 2041 • Population and Water Use • New Source Criteria • 2
Purpose of the Source Supply Study • Review and prioritize known sources – 3 primary sources nearing capacity (7-10 years, subject to usage and growth) – Water enabler of OCP goals – Emerging challenges/opportunities to water supply • Develop a refined solution set – Evaluate and identify conservation, optimization and source/supply opportunities – Phased, incrementable, affordable, sustainable, resilient, flexible approach 3
CURRENT SHARE OF TOTAL SUPPLY 6% Norrish 12% Cannell Groundwater- Wells 82% • 80km of transmission pipe + multiple reservoirs and NWTP • License capacity > reliable capacity triggers need to predict long term adequacy • Portfolio of Sources: individual strengths offset weaknesses of others 4
Source Review Capacity Portfolio Generally adequate capacity High-elevation, good quality source • Cannel Fraction of supply needs; small watershed • under normal conditions however Best for winter demands or summer • new demands, drought and demand complement turbidity spikes may affect supply Reliable, low-treatment supply all year resiliency in 7 to 10 years. • Ground- Trending water quality concerns and • water Wells higher operational footprint Distributed source to address summer • use and demands from growth Emerging gap A go-to source for unplanned events (e.g. Largest source with advanced treatment • turbidity) and planned long- Turbidity spikes lowers capacity • Norrish term growth. Transmission limited by pipe size • Concerns regarding ability and cost to • expand source storage 5
Primary Opportunities for Water Supply Key Ingredients for Solution Sets • Importance of an agreed upon direction for water conservation. • Opportunity to resolve supply constraints or Optimization through transmission infrastructure. • Need to establish a reliable source portfolio including prioritized expansion. 6
Role of Demand Planning Water Use Profile Prepare: the Commission and its customers • for new initiatives and projects. 14% Evaluate: choices to support broader • 12% community goals. 50% Engage: test actions for staff to deliver on • 24% political and public aspirations . Ensure: compliance with regulations and best • practices. Define: capital projects and levels of service . • Residential Commercial Agriculture NRW The use of multiple conservation tools over the 10 years demonstrates the ability of the public to adapt and conserve. But to keep demands lower still 7 will require program enhancements.

Strategically prioritize sources using criteria that enhance our portfolio. Criteria to Prioritize Solution Sets Next Steps Consistency over time e.g. droughts • Resiliency Amount and severity of hazards; risks • Ability to phase for increasing demands/peaks • Adequacy License/regulatory assurances • Proximity/convenience to system needs • Serviceability Operational footprint e.g. effort/management • Relative cost performance of Solution A to B • Affordability Cash flow and rates considerations • Public perception of water quality • Desirability Stakeholder conflicts • 16
Solution Sets: Source Evaluation • Apply criteria to sources to prioritize supply strategy • Solution sets make best use of conservation, optimization and source supply Outdoor Water Leak Kits Restrictions Rainny Wells Fraser River Stave Lake Miracle Valley Expand Norrish Other Sources 17
