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.

* 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
