Utilities Department MenuWastewater Services
Our Wastewater Quality team serves more than one million people and treats more than 60 million gallons of wastewater each day. That means what goes down your toilet, sink, dishwasher, shower or drain comes to us at one of our four wastewater treatment plants to be filtered, disinfected, sanitized and then discharged into local waterways as EPA Grade B wastewater.
Protect Your Pipes
Don't dump just anything down your drain.
Commercial and Industrial Pretreatment
In addition to residential education, we also run commercial and industrial pretreatment programs, where we assist food service facilities, medical and automotive facilities, medical marijuana facilities and industrial manufacturers to ensure they're disposing of their waste properly so it does not enter the sewer system.
