Denver Water’s collection system covers more than 4,000 square miles, and we operate facilities in 12 counties. Denver Water also operates and maintains more than 3,000 miles of distribution pipe — enough to stretch from Los Angeles to New York — as well as 20 dams, more than 20 pump stations, four treatment plants and more.
With so much to maintain, you may see crews replacing pipe or building new facilities. Whenever possible, Denver Water will notify you in advance if there are plans for construction project in your neighborhood. If you have questions, you can always call 303-893-2444.
Gross Reservoir Expansion Project
Construction is underway to raise the height of the dam by 131 feet, tripling the reservoir’s capacity from approximately 42,000 acre-feet to 119,000 acre-feet.Project website
