SCRD Raw Water Reservoir Project

Project Drivers

§ Diversion of water to a reservoir during periods of high precipitation and high creek flow (wet season)

§ Use of reservoir water during periods of low precipitation (dry season)

Sunshine Coast Tourism 2014

Project Stages

Phase 1:

§ Water Demand Analysis

§ Site identification and preliminary desktop evaluation

§ Preliminary Multi-Criteria Analysis (MCA)

Phase 2:

§ Detailed site evaluation (desktop and field assessment)

§ Conceptual design

§ Class D cost estimates

§ Detailed MCA Completed to date

Water Demand Analysis

Demand Reduction Factor from 2010 Supply Deficit (m3)

Demand Reduction 2025 2035 2050

Population 26,000 32,000 43,000

0% (zero reduction) 2,454,000 3,392,000 5,114,000

10% (minimal reduction) 2,002,000 2,837,000 4,366,000

20% (moderate reduction) 1,640,000 2,391,000 3,770,000

33% (high reduction) 1,245,000 1,811,000 2,988,000

Target reservoir volume: 900,000 m3 - 1,300,000 m3
