Billing and Rates

The City's sanitary sewers and storm drainage facilities are two completely independent systems. Denver's storm drainage facilities keep storm water safe, removing as many pollutants as possible from the water and creating a safe flow for storm water during storms or snow melts. These facilities are massive in scope and must be engineered, operated and maintained.

Billing

Storm Drainage — billed annually based on a formula using the lot size, the total impervious (or impermeable) surface area, and our billing rates. 

  • Return payment by mail
  • Pay online with StormPay, and sign up for eBilling to receive your annual invoice electronically
  • Payments cannot be made by telephone

Sanitary Sewer — billed monthly in combination with the Denver Water Department
