From the Fort Collins Coloradoan (Kevin Duggan):
Wastewater rates will increase 9 percent in 2011 and 8 percent in 2012, primarily to continue paying off a $31 million project that is rebuilding a wastewater treatment plant at Mulberry Street and Riverside Avenue. Water rates would increase 3 percent in 2011; no increase is expected in 2012. Stormwater rates are not expected to increase either year.
