In 2011, Denver City Council approved a series of sanitary sewer and storm drainage rate increases, effective July 1 of each of the years 2011, 2012, 2013.
Council also approved annual rate increases each July 1 thereafter (beginning July 1, 2014), based on the consumer price index for the Denver-Boulder-Greeley metropolitan area for the preceding year.
The increase in the CPI-U (Consumer Price Index-All Urban Consumers) for 2013 was 2.8%. Accordingly, this increase is reflected in Denver's sanitary sewer and storm drainage rates, effective with all bills generated on or after July 1st, 2014.
Denver's Wastewater Management Division uses the revenues generated from its ratepayers to maintain the quality and reliability of its underground pipes and infrastructure; plan and construct high priority projects; and support RTD’s FasTracks construction by upgrading or realigning city lines. The rate changes are needed to fund vital improvements to Denver’s sanitary sewer and storm drainage systems.
