Water Supply and Reuse

The City and County of Broomfield (CCOB) has two primary sources of water: 

• Treated water purchased from Denver Water. 
• Raw water supplied to Broomfield’s Water Treatment Plant by the Colorado-Big Thompson (C-BT) Project and Windy Gap Project under the management of Northern Water.

Broomfield is also a participant in the Windy Gap Firming Project (WGFP). Participation in the WGFP will provide valuable water storage and water supply reliability for Broomfield customers.

In addition to its potable (drinkable) water supply, Broomfield also has a robust reuse (non-potable) water system. The reuse water system allows Broomfield to use treated wastewater effluent (liquid waste that can be discharged into a body of water) a second time for irrigation and other non-potable purposes.

Broomfield's Water Reuse System

The keystone of CCOB’s water efficiency efforts is the non-potable distribution system, also known as the reuse system. CCOB’s reuse system provides water to approximately 940 acres of irrigated parks in the city. There are approximately 1,500 additional acres of non-city owned areas served by the reuse system, including Arista, Flatirons Mall, Legacy High School, Anthem and Interlocken Business Park along Highway 36.

The reuse system is extremely beneficial because it allows CCOB to expand its water supplies beyond a single, one-time use and reduces the amount of treated domestic drinking water that would otherwise be needed for these irrigation purposes. Broomfield’s reuse system addresses as much as 20% of the overall water demand in the city.
