Wastewater Collection System

The City provides all services related to maintenance, repair, and replacement of the existing wastewater collection system infrastructure. This is accomplished with recognition that service to our customers requires 24 hours a day, 7 days a week problem-free continuous operation. If you are aware of a sewer problem, please call (509) 625-7900 to report the problem.

Sewer Construction

The Sewer Construction program ensures that the wastewater collection system and the associated sewer pipes and pump station facilities consistently meet the needs of the community, are properly operated and maintained, and meet water quality standards. Major capital improvements of the wastewater collection system include elimination of septic systems to protect the aquifer, elimination of obsolete sewer lagoons, and improvment and/or replacment of the sewer trunk lines.

Sewer Construction Schedule

Each year the City's Engineering Services Department develops and maintains a construction schedule for the variety of public infrastructure construction projects planned. You can review the schedule, which includes sewer projects, to keep up to date on the status of new projects by clicking here. In addition, any project which may impact traffic movement throughout the City is posted on the City's Home Page. You can review those projects by clicking here.

Sewer Maintenance

The Sewer Maintenance Division provides a problem-free wastewater collection system at minimum cost to the ratepayer. The City maintains three types of systems: Sanitary only, combined sanitary and stormwater, and stormwater only infrastructure.

Complete inspections of all new or repaired collection system projects within the City sewer service area are conducted. Existing lines are regularly inspected and preventative maintenance is conducted. Repairs are made to collapsed lines, older lines are upgraded, manhole rings and covers are replaced, modifications are made to reduce maintenance requirements, and regular cleaning of storm inlet structures are conducted.

Rehabilitation of existing collection system infrastructure includes the use of no dig (trenchless technology) as well as direct dig and replacement options. Trenchless options (pipe lining and spot repairs) are utilized where possible to reduce maintenance costs and minimize traffic disruption.

How to Report a Sewer Problem

The Wastewater Management Department recognizes the value of preventative maintenance to keep sewer costs down, minimize the need for emergency repairs, and effectively maintain the wastewater system infrastructure. If you are aware of a problem, please call (509) 625-7900.
