Why is it so expensiveBecause we are doing high level (tertiary) treatmentThis 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 BayAvoids $3m outfall expansionIn keeping with Federal and Provincial policies which encourage the use of reclaimed waterGoal was set in Sechelts 2011 Sustainability Action PlanSustainability Action Plan Other goals of the Plan;Reduce noise and smell to the greatest extent possiblePursue opportunities to recover resources from treated effluentMaximise energy efficiency, reduce water consumptionBase infrastructure decisions on full life cycle costsEnsure that municipal infrastructure is integrated and energy efficient and has the lowest environmental impact possible.
