The Wastewater Management Division, part of the City and County of Denver Department of Transportation and Infrastructure, maintains more than 1,500 miles of sanitary sewer and more than 800 miles of storm drainage underground lines and pipes.
Wastewater refers to any water that has become contaminated by human influence and is broken into two groups: sewage and stormwater, which are managed through separate systems in Denver.
Assistance with sanitary sewer charges, billed in combination with Denver Water, and storm drainage charges calculated annually and billed in semi-annual installments.
