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, but is capable of handling almost twice that amount.
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.
