Arapahoe County Water and Wastewater Authority (ACWWA)
Providing Long-Term Sustainable Water Supplies
The service area of the Arapahoe County Water and Wastewater Authority (ACWWA) covers roughly 5,000 acres in the southern part of Arapahoe County, serving approximately 3,000 residential and commercial accounts. ACWWA also supplies small developments in Elbert and Douglas counties and provides wastewater service to the Cottonwood Water and Sanitation District.
ACWWA currently draws from 17 deep aquifer wells to serve its customer base. With declines in its existing groundwater supplies, ACWWA determined it could not rely solely on non-tributary water sources to meet its long-term needs. In 2009, ACWWA initiated its multi-phased “ACWWA Flow” project to obtain renewable surface water from the South Platte.
As part of this plan, United acquired 4,400 acre-feet of renewable water for ACWWA. That water is currently being adjudicated. ACWWA also has access to United’s extensive diversion and delivery system, including United Diversion No. 3, the United No. 3 Reservoir, the Beebe Draw Raw Water Line and the Beebe Draw Well Field.
As part of the ACWWA Flow Project, United designed and constructed a 1,400 acre-foot storage reservoir in the ACWWA service area at E-470 and Chambers Road. From start to finish, the planning, permitting, design, construction and delivery of the reservoir took only nineteen months.
The ACWWA Flow project is a sustainable solution involving renewable water resources and innovative water collection and treatment technologies. ACCWA began receiving renewable water from United via the ECCV Northern Pipeline in 2013.
