Sanitary Sewer Billing
To reduce costs and as a convenience to customers, a combination bill was developed. The sanitary sewer bill is based on the water consumption metered by the Denver Water Department. This information is included on your combined bill.
Every residential customer has a two-month winter billing period. Metered water consumption for this winter period established sanitary sewer charges for the entire year. Even though your water use may increase during the summer, your sanitary sewer charges will remain constant.
The sanitary sewer charge for commercial property is based upon actual metered consumption in each billing period during the year.
