Important Notice

Discolored water has been intermittently reported in ACWWA’s system (near the intersection of Jordan and Broncos Parkway). The ACWWA operators are currently investigating this issue. 

What should I do if my water is discolored? If discoloration of your water occurs, try running only the COLD water at one faucet for about 5 minutes and you should see that the water becomes clear. (Note that because running the hot water rather than cold water pulls from the hot water heater, the water may not run clear.) If the water doesn’t clear up after 5 minutes, wait for a few hours and try running the cold water only again. While the water is safe to drink, it is best to avoid doing white laundry until the water runs clear.

If the water is still discolored, please call our customer service at 303-790-4830 Extension 0 during business hours, for after hours please call our operators at 303-886-2059, or email us at ContactUs@ArapahoeWater.org, so we can investigate why the water continues to have discoloration. Even if you are living in an apartment or multi-family unit, it’s important to let us know.

What causes the water to be discolored?

This discoloration consists of naturally occurring harmless minerals. Most often, why this occurs are minerals, like iron, settle in the bottom of the pipelines. Then when there is a large demand for water, (i.e. irrigation or construction) the speed and pressure of the water’s flow can stir up these minerals and they can show up temporarily in the water. To help lessen or prevent the discoloration, our operators routinely perform Water Main Flushing.

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.
