The Department’s Wastewater Division collects, treats and disposes of all of the City’s sewage at the San Luis Rey Wastewater Treatment Plant and the La Salina Wastewater Treatment Plant. All sewage is treated to levels set by the Environmental Protection Agency. The San Luis Rey plant serves areas east of I-5 and the La Salina plant treats sewage from areas west of I-5, downtown and along the coast. Staff is responsible for operating and maintaining over 450 miles of pipelines and 34 lift stations.
Although products like facial tissues, dental floss, cotton swabs, and kitty litter may flush down the toilet, they can cause clogged pipes for you and your neighbors. See Will It Flush? to find out more, and many thanks to City of Spokane Department of Wastewater Management for sharing its entertaining and educational video in partnership with WEF.
