The Water & Waste Department is responsible for the maintenance of the sewer system, the storm sewer system, lift stations, and the sewage lagoons.
The sewerage system consists of:
- one main lagoon system which serves Porter Creek, Hillcrest, Takhini, Downtown, and Riverdale
- one minor lagoon system that serves Crestview
- four major lift stations and a flush tank
- five minor lift stations
Since the lagoon system was constructed it has operated as a closed system similar to a wetland treatment system. Effluent from the primary cells flows into the second secondary cell where it dissipates through evaporation and infiltration.
