Questions about rates

Denver’s sanitary sewer system collects and transports waste from homes and businesses using underground conveyance networks that lead to the  Metro Wastewater Reclamation District  (Metro) for treatment. Metro is the wastewater treatment authority for much of metro Denver and parts of northern Colorado. Sewage runs through the sanitary sewer system to Metro, where it undergoes a variety of biological and chemical processes that remove 95% of pollutants before the treated water is discharged to the South Platte River.

Metro is undertaking significant, expensive capital projects to handle regional growth and to comply with EPA clean water requirements. These costs are passed along to Denver and other regional water and sewer districts.

Every year, Wastewater Management Division's payments to Metro represent 50-60% of our operating and management expenses in the sanitary sewer sub-fund. Actual payments totaled $44,859,512 in 2013.
