Wastewater Department

About Wastewater

The Wastewater Department operates and maintains two wastewater treatment plants and 72 lift stations. These facilities convey and are permitted to treat approximately 16 million gallons of wastewater per day during dry weather periods and up to 48 million gallons per day during wet weather periods.


To meet the demands of current growth, the capacity expansion of Dallas Salmon Wastewater Treatment Plant was completed in October 2010. SWWRF was completed in 2012 and serves the southwest area of the City. The department’s operations staff works a seven day a week schedule to ensure proper treatment operation, and along with maintenance personnel, is on call for emergency situations. Included in these facilities are approximately 200 pumps of various designs from 3 horsepower (hp) to 185hp; 10 centrifugal blowers 40hp to 200hp, and many other specialized pieces of equipment required to provide adequate treatment of the City’s wastewater.
