Pump Stations Owned by the City The City owns 19 sanitary sewer pump stations (sometimes referred to as lift stations) at various locations throughout the City. In portions of the City, it is not possible to have waste water drain by gravity alone and it must be pumped to a higher elevation to allow it to drain into the City's sanitary sewer system. The City owns a sanitary sewer pump station located behind the Rural King building on the east side of the City named the K-Mart Pumping Station after the business that operated there for years. This station serves the businesses and shopping centers along Route 121 south of Route 36, including Airport Plaza, Wal-Mart, Rural King, etc. The pump station has been rebuilt over the years and modified to increase its capacity to meet the needs of the developing area. The station is old and unsafe for maintenance crews to service due to its extremely confined design. The station needs to be replaced to erisure its continuing reliability to safely serve the businesses and future development in that portion of the City. Page � 1
