Why is it “so expensive”
• Because we are doing high level (“tertiary”) treatment
• This added about $5m to the cost
. . . However . . .

Why are we doing high level treatment?
• Enables widest range of options for reuse of water.
• 90% reduction in contaminant load to Trail Bay
• Avoids $3m outfall expansion
• In keeping with Federal and Provincial policies which encourage the use of reclaimed water
• Goal was set in Sechelt’s 2011 Sustainability Action Plan

Sustainability Action Plan
Other goals of the Plan;
• Reduce noise and smell to the greatest extent possible
• Pursue opportunities to recover resources from treated effluent
• Maximise energy efficiency, reduce water consumption
• Base infrastructure decisions on full life cycle costs
• Ensure that municipal infrastructure is integrated and energy efficient and has the lowest environmental impact possible.
Liquid Waste : “to treat effluent to the highest levels”

* For comparison, all capital costs assume biosolids composting by Salish Soils
Need to add $3.2m of DoS costs to all bid prices to get the “Project Cost”
**Base bid, Lot L projects include new, relocated, odour controlled pump station at Ebbtide
