Wastewater Collection System

The city's Wastewater Collection System maintenance staff is charged with protecting the public’s health and safety by monitoring and repairing the city's wastewaster infrastructure through inspection for root intrusion, breaks, and infiltration. Flushing of sewer lines ensures they are free from obstruction.

Wastewater Treatment Plant

When the water you use goes down the drain, it is treated at the city’s Wastewater Treatment Plant.

Treating wastewater is necessary to protect the health of the public and the environment.

The Wastewater Treatment Plant is located nine miles north of the city in Weld County and treats an average of 3.5 million gallons of wastewater each day.
About 10,000 tests are performed each year as wastewater travels through the various stages of treatment and discharge to ensure it meets all the requirements of the Clean Water Act.

During the spring and summer months, the facility’s effluent water, or water that flows out of a treatment plant, is discharged out of Bull Reservoir primarily to Bull Canal where it is used mostly for crop irrigation. Some effluent water is released to Big Dry Creek, which eventually ends up in the South Platte River.

    Your Toilet is NOT a Garbage Can

    Don’t flush trouble! Labels on products may say they are “disposable” but disposable wipes and other products can clog sewer lines. Think trash, not toilets.

    Don’t flush:

    • Disinfecting wipes
    • Baby wipes
    • Mop refills
    • Towelettes
    • Paper towels
    • Q-tips
    • Dental floss
    • Other trash
    • Sanitary products
    • Prophylactics
    • Medical syringes

    FOG Fats, Oil and Grease

    Cooking grease can cause big problems for your sanitary sewer system! Pour grease, oil and fats into a container, let it solidify and throw it away, don’t pour it down the drain. It may be liquid when you pour it, but it will harden and cling to the walls of your pipes eventually clogging your sewer system. And that is an expensive and unpleasant problem to have.
