Water Maintenance is responsible for operating, maintaining and repairing the water distribution system; installing new water mains, implementing the backflow prevention program; reviewing plans for new water mains and services; approving new water service applications; and maintaining records of the distribution system.The distribution system is the network of pipes and the associated fittings, valves, hydrants and appurtenances that transports water throughout the City. Most of the distribution system is located within the city street right-of-ways. A small percentage is located in cross-country easements.Water is pumped into the distribution system from the water treatment plant on Kenoza Lake. The distribution system includes approximately 235 miles of pipe that range in size from 2-inch up to 36-inch. Pipe materials include unlined cast iron, lined cast iron, ductile iron, transite, and PVC. Pressures and storage throughout the system are maintained by three concrete storage tanks and 5 booster pumping stations throughout the City. The pumping stations operate to fill storage tanks and/or pressurize separate high pressure zones.
