The sanitary and storm sewer collection systems consist of two separate pipe networks designed to carry the sanitary wastewater and storm water runoff, respectively. The sanitary sewer collection system includes approximately 290 miles of pipe in various diameters and 20 lift stations, which transport the sanitary wastewater throughout the city to the wastewater treatment plant. The storm sewer collection system consists of 140 miles of pipe and open ditch, and two pumping stations which carry the runoff from streets and adjoining properties to Hay Creek, Apple Creek and the Missouri River.
