Pump Stations

The city’s sanitary sewer system consists of a maze of underground pipes, numerous manhole structures, regulator and overflow devices, river siphons, and a network of pump stations located throughout the city. The sewer system is designed to work primarily by gravity, which means it is designed so that wastewater flows downhill from the source to the treatment plant. Due to the relatively flat terrain in the Defiance area, it is necessary to lift the water at various locations in the city, using electric pumps, so that gravity can again take over and continue the flow toward the plant.

The City has a network of pump (lift) stations positioned at key points throughout our sewer system. These pump stations are located both inside and outside of the City limits, for the most part pumping stations were named for their geographic location in the City.

The main collection point for wastewater in the City of Defiance is the Kingsbury Pump Station. This pump station, located in Defiance’s Kingsbury Park, collects most of the City’s wastewater, which then pumps it through a 20" force main, approximately 2 miles to the wastewater treatment plant for treatment.

For more detailed information on individual pump stations throughout the city see our Pump Station Details.
