Water Drainage System in Yellowknife

Fiddler's Lake Lagoon

If you are worried about the water facilities in Yellowknife due to below 0°C temperatures, be happy! The water/waste drainage system is insulated with polystyrene foam so that the fluid will not freeze in the pipe. Yellowknife also has a network of gravity-fed sewage, which means that the sewage will not need any source of pressure to pump down the water. Due to the slanted sewage system, the city won't need to waste power on waste management. In addition, areas that is not covered with the sewage system is provided with trucked water and sewage in and out. The sewage and the waste is pumped to series of lakes called "Fiddler's Lake Lagoon", where it is held and allowed to naturally decompose
The water provided is refined and treated with disinfectants and fluoridation from Yellowknife River. It is then stored in a 9 million liter reservoir. After, it is distributed to the community through 62 km water pipes. 
The storm-water system in Yellowknife prevents the water bodies around the city to its natural state. When rain or melted snow is carried away to storm drains or catch basins, it also collects pollutants from roofs, lawns, driveways, parking lots, and roads.
