The Northern Project is a collaboration between two South Metro Water members, East Cherry Creek Valley and Arapahoe County Water and Wastewater Authority, to deliver new renewable water supplies to the region and reduce dependency on nonrenewable groundwater. The project includes the 31-mile Northern Pipeline and the state-of the-art Northern Water Treatment Plant. ECCV and ACWWA serve Centennial, Foxfield and unincorporated areas of Arapahoe County. Five other South Metro Water members share capacity on the pipeline: Castle Rock, Centennial, Cottonwood, Inverness, and Stonegate.
The treatment plant, completed in 2012, uses advanced technology to produce up to 11 million gallons of treated water per day. At full capacity, it will be able to treat more than 33 million gallons of water per day.
