Arapahoe County Water and Wastewater Authority (ACWWA) is a political subdivision formed by an agreement between Arapahoe County, and the Arapahoe County Water and Wastewater Public Improvement District (PID) for the purpose of developing water resources, systems and facilities, wastewater collection and treatment facilities for the ACWWA service area. ACWWA serves an area of more than eight square miles in the southeastern Denver metropolitan area, approximately 10 miles from downtown Denver.

ACWWA’s service area is primarily in Arapahoe County, but includes some property in northern Douglas County. It is comprised mostly of office complexes, commercial and light industrial areas. Significant multi-family residential development is being added, primarily in the eastern part of the service area. ACWWA also provides wholesale wastewater treatment service to the Cottonwood Water and Sanitation District in Douglas County. ACWWA provides water service to the Town of Foxfield as well, and will soon serve other residential subdivisions east of Parker Road and south of Arapahoe Road. ACWWA also provides water service to a residential subdivision in northwest Elbert County.
