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