    Water Treatment Frequently Asked Questions

    Frequently Asked Questions

    What year was the Water Treatment Facility built?

    The facility was built in 1980 on property donated by Oscar Arnold. This land donation includes the property used for the Northwest Open Space and Oscar Arnold Nature Area with the caveat that his farming equipment remains permanently on display at the Water Treatment Facility.

    Where does Northglenn's water come from?

    Snow melt and rain runoff travels down Berthoud Pass, flowing into Clear Creek, coming to rest at Standley Lake for water storage. Standley Lake water is distributed to three municipalities, Northglenn, Thornton, Westminster for drinking water treatment, as well as distribution to the Farmers Reservoir & Irrigation Company (FRICO).

    Where is Northglenn's drinking water stored?

    Once treated, Northglenn’s drinking water is stored at several locations within the city. The Water Treatment Facility itself stores 830,000 gallons of drinking water in two enclosed clear wells. Three of the four low zone tanks located near Community Center Drive (the fourth tank, closest to the Justice Center is own by Thornton), hold 60% of the City’s drinking water, with a combined capacity of seven million gallons. The last 750,000 gallons of drinking water are stored in a high zone tank located off 104th.
