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

5 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

6 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”
