Wastewater Rate Increase to Protect Against Flooding, Update Aging Infrastructure and Keep Pace with Growth

On June 14, 2016, Denver Public Works Department received approval from the Denver City Council to increase annual storm and sanitary sewer rates to help address a backlog of needed storm drainage improvements and keep pace with growth.

The fee increase, which will be implemented over a five-year period starting July 1, 2016, will support $383 million in citywide storm drainage improvements to address:

  • Neighborhood Needs ($53M) - citywide storm drainage improvement programs
  • Focus Basins ($78M) - critical storm drainage capital projects citywide to reduce flood risk to life and property, including the Platte to Park Hill: Stormwater Systems Program ($206M), which focuses on neighborhoods east and north of downtown that are most at risk for severe flooding during storms
  • Focus Waterways ($25M) - restoration and flood mitigation in partnership with the Urban Drainage and Flood Control District, U.S. Army Corp of Engineers, Federal Emergency Management Agency, etc.
  • Water Quality ($21M) - projects that improve the health of Denver's waterways

In 2016, rates go into effect July 1st. Beginning 2017, new rates go into effect January 1st each year. 

With the rate increase, the city will be able to invest about $30 million annually in stormwater capital improvement projects citywide — up from $20 million annually. Denver will also be able to increase the amount it spends on its sanitary sewer system from an average of $2.5 million per year to an average of $8 million per year over five years.

As a result of the rate increase, the average residential rate payer will pay roughly $23 more per year for the next five years for both storm and sanitary bills combined. Denver’s storm and sanitary bill rates are currently about $100 lower than the average for other larger Colorado cities. With these proposed rate changes, Denver would be about $60 below the average in 2017, when the first full year of the rate change takes effect.

Denver Wastewater customers will receive information about how the rate change will impact their bills and what it will fund when they receive their bills. Questions about the rate increase can be directed to pw.comms@denvergov.org.
