Water Treatment Plant

Before water reaches Northglenn faucets from Standley Lake Reservoir, it is filtered at the city’s Water Treatment Plant.

All harmful, or potentially harmful, elements are removed or inactivated to make the “raw” water from Standley Lake fit to drink.

The Water Treatment Plant operates 24 hours a day, 365 days a year. More than 59,000 tests are done on the water each year so chemical feeds can be adjusted as necessary to ensure that residents receive the highest quality and most aesthetically pleasing water possible.

The Water Treatment Plant treats and pumps out approximately 3 million gallons of water per day in the winter and up to 10 million in the summer to meet the demands of customers.

Operators have been certified by the Colorado Department of Public Health and Environment. They ensure coverage of the plant around the clock and monitor the treatment system from our raw water source to the finished product, which you see at your water tap.

Wastewater Treatment Facility

Water that has been poured or flushed into your drain is treated at the city’s Water Treatment Facility.

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

The Wastewater Treatment Facility is located on 320 acres of land in Weld County. The facility treats an average of 3.7 million gallons per day, but is capable of handling almost twice that amount.

About 10,000 tests are run each year as the wastewater travels through the various stages of treatment and discharge to ensure that it meets all regulations set forth in the Clean Water Act.

The Colorado Department of Public Health and Environment inspects the facility and dam and also performs independent water tests at least twice per year. The Environmental Protection Agency spot checks without notice to be sure the facility and wastewater effluent (treated wastewater outflow) meet all regulations. In addition, the city must submit a report to both of these agencies each month.

During the spring and summer months, the facility's treated effluent water is discharged primarily to Bull Canal and is used for crop irrigation. Some effluent water is released to Big Dry Creek and eventually ends up in the South Platte River.
