City of Spokane Wastewater Management

The purpose of the Stormwater program is to ensure that stormwater systems and their associated catch basins, dry wells, water quality treatment bioinfiltration swales (208 swales), trunk and lateral storm drain lines consistently meet the needs of the community and are properly operated and maintained. In addition, recent stormwater planning and new stormwater programs are being implemented in response to our Eastern Washington Phase II Municipal Stormwater Permit. The permit was issued from the Department of Ecology in 2007. To view the permit please click on the link Eastern Washington Phase II Municipal Stormwater Permit.

Questions about stormwater issues and stormwater rates are common. To help understand this topic, the City developed a document in the year 2000 to answer a variety of frequently asked stormwater questions. Even though the rates have changed, many of the questions and answers are still applicable. To review this document click here (PDF, 124K).

The City Wastewater Management Department is interested in knowing about, understanding, and responding to flooding and stormwater quality problems. To report a flooding or stormwater quality problem, call (509) 625-7900.

The City of Spokane funds its stormwater management program through a utility rate structure. Each residential utility customer is charged monthly on their sewer utility bill, whereas commercial/industrial customers' rates vary depending on the size and configuration of their facility (impervious area).

The City offers rate credits to private commercial/industrial customers if appropriate on-site stormwater disposal and treatment facilities are provided and maintained; please call (509) 625-7900 for more information and an application form.
