Paying online?

The City of Denver recently implemented a security enhancement to better protect our online payment processing system.  As a result of this enhancement, we are no longer able to accept payments from non-current browsers. If you are using an older browser version, please upgrade your browser to the most current version so that you can access the online payment service.

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 — calculated annually based on a formula using the lot size, the total impervious (or impermeable) surface area, and our billing rates. Starting July 1, 2016, this annual fee will be billed semi-annually.

  • Online: use StormPay — no fees to pay with Visa/MasterCard/Discover online; save postage and paper
  • Go paperlesssign up for eBilling to receive and pay your storm bill via e-mail
  • By Mail: Send a check or money order to P.O. Box 17827, Denver, CO  80217-0827
  • Pay in Person: Bring payment to 2000 W. 3rd Ave, Denver CO, 7:30 a.m.-4:00 p.m. Monday-Friday
  • Payment cannot be made by phone.

Due dates and the dollar amounts due are posted on your bill. The second half of your annual storm charges will be billed to you six months after you received the first. You will have the option of paying in one, two, or three installments for each semi-annual bill.
