Water and Sewer

The majority of the City of Yellowknife is on piped water and sewer service.

The current piped water and sewage system is composed of 4 pumphouses and 2 recirculation stations, 3 reservoirs, 11 lift stations, 62 km of buried water main and a slightly smaller quantity of sewer main, poly summer water line (above grade generally), approximate 11 km of forcemain, and a sewage lagoon system complete with control structures.

The City of Yellowknife Public Works Department flushes and cleans the entire City water system on an annual basis in order to ensure a safe, healthy and odorless supply 24 hours per day, every day of the year.

To insure our water remains at the highest standard for domestic use, continuous CL2 monitoring is done 24/7 at six locations. Elevations in the reservoir and bacteriological samples are done monthly at three locations.

Only Old Town, Latham Island, Ndilo, Kam Lake Industrial Park, Con and Rycon Trailer Park, commercial buildings at the Airport and some commercial buildings along Old Airport Road receive truck water delivery and sewage pumpout. Trucking currently services approximately 680 residents or just under 4% of the population not including commercial/industrial demand (about 1,600 employees).

Surface Water Lines

Summer water lines are located north of School Draw Avenue, in Old Town and on Latham Island.

• Start-up: May 29^th  (water lines will be turned on and residents can connect service lines)
