General Questions

The Wastewater Management Division which is part of the Public Works department, builds, operates and maintains Denver's sanitary sewer system and storm drainage system. We maintain more than 1525 miles of sanitary sewers and 793 miles of storm drainage facilities.

One bill is for sanitary sewer charges. This is prepared monthly, and is combined with your water bill. Once a year you receive another bill for storm drainage. The storm drainage bill is sent to every owner of improved property within Denver.
Sanitary sewer charges are for the collection, treatment, and disposal of water going down your sinks, drains, and toilets. Storm drainage charges are for the collection and disposal of rain water and snow melt. The City's sanitary sewers and storm drainage facilities are two completely independent systems.
