Public Notification of Discharge


The City of Whitehorse will commence discharging treated effluent from the Livingston Trail Long Term Storage Lagoon to the Yukon River during the period September 2, 2014 through December 15, 2014 with an average of 20,000 cubic metres per day.

The treated effluent discharge is required to lower the wastewater levels in the lagoon to provide room for future inflows into the Livingston Trail Facility and to reduce odours from the Lagoon. This discharge is completed under Water License MN93-001.

Should you have any questions please contact Matthew Sider, Water and Waste Technologist at 633-7404.

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.
