From The Denver Post (Caitlin Gibbons):
The rate hike, effective July 1, reflects the pass-through cost of the Metro Wastewater Reclamation District facility being built near Brighton and the cost of maintaining city sewer lines…
Mix said this is the city’s first sewer-rate hike since 1995. But it won’t be the last: Sewer rates will increase by 15 percent in 2012 and by 10 percent in 2013, and each year thereafter based on the Consumer Price Index. About 59 percent of the average Denver sewer bill is paid to Metro. The rest is used to maintain the sewer system for collecting and transporting waste from homes and businesses to Metro for processing.
Metro’s bill to Denver increased by about 34 percent, utility spokesman Steve Frank said. The city will pay Metro about $45 million this year. Frank said Denver’s bill went up “because of the amount of water and how heavily polluted the water is.”[…]
Denver Wastewater — managed by the city’s Public Works department — is increasing storm-drainage rates by 20 percent.
