2015

The City of Abbotsford has one

of the lowest per capita water uses in the Lower Mainland.

Other Sources Considered

Hayward Lake – ($220M NPV) - Potential contamination from Mission landfill leachate. Pumping costs.

Stave Lake – ($224M NPV)

Fraser River – ($232M NPV) - Requires significant pumping and has significant turbidity spikes.

Harrison Lake – ($334M NPV) - Long distance and high cost. Pumping costs.

Dickson Lake – ($239M NPV plus dam upgrade costs) - Potential for difficult and lengthy environmental process. No redundancy.

Chilliwack Lake – ($374M NPV) - Long distance and high cost. Potential geotechnical challenges.

Most of these source options did not address the required filtration of the Cannell Lake water source.

New Water Source – Stave Lake

Consists of an intake, pump station, water treatment plant and transmission mains from Stave Lake, through Mission and into Abbotsford. Includes a crossing of the Fraser River.

Stave Lake Intake Design

• Many design options were considered and ranked by costs, as well as potential impacts to the community and environment.

• An underground tunnel connecting intake with pump station avoids disturbing known archeological sites.

• Site will be buffered by trees along shoreline to shield pump station from view.

Next Steps

• Focus on federal and provincial environmental permitting and site review.

• Consultation with public, stakeholders and First Nations.

• Investigate procurement models for Project.

Construction 2011-2012

Construction of the transmission main south of the Fraser River will begin this spring. This will improve the ability of the AMWSC to meet maximum day demands in the short term.

Grant Funding

• Applied for P3 Canada Fund funding in June 2010

• Potential for 25% capital funding

• Procurement business case was completed by Deloitte/CH2M Hill advisor team

• Will also be seeking Provincial funding sources for this project
