Sewer/Wastewater

Responsibilities

The Utility Services Division of Public Works is responsible for the Water Treatment Plant, Wastewater Treatment Plant, Wastewater Collection, and Water Distribution programs. The Water section has the responsibility to provide clean, clear, potable water to its utility customers, to maintain that high quality, and deliver it economically and plentifully to the consumer. This has been accomplished with the help of the Water Filter Treatment Plant along with various wells that the City operates. Water Distribution crews keep the water system operating efficiently, including transmission lines, mains, valves, reservoirs, hydrants, meters, pumps, etc.

Treatment

Charged with treating industrial and domestic wastes, the Wastewater or Sewer section performs a vital function relating to citizens' health, both here and downstream on the Columbia River. Wastewater Collection crews ensure that the system is leak and seepage proof, unblocked by sand, grease, or roots, and graded to move wastes efficiently to the Wastewater Treatment Plant where the treated water is put back into the river cleaner than when it was taken out.
