Sewer Maintenance


The Sewer Maintenance Bureau operates and maintains a separate wastewater collection system (WWCS) and separate storm sewer system (MS4) within the corporate limits of the City of Dayton.

The WWCS is comprised of a network of gravity sewers and pumping stations that convey wastewater to an advanced wastewater treatment plant operated by the Division of Water Reclamation.

The MS4 is comprised of a gravity piping system and pumping stations that convey storm water runoff to rivers, streams and waterways during rain events.

The Sewer Maintenance Bureau also operates a series of flood control pumping stations and flood control valves/gates constructed as part a levee system along the major river corridors that run through Dayton.


The Dayton Sewer System came into existence due to a City Council decision in 1889 to pave the downtown streets. Construction on the system began in 1890 with early maintenance provided by the Sewer Inspection Office.

The Division of Sewer Maintenance was established in 1908 and was recently merged with Water Distribution to form the Division of Water Utility Field Operations, established in 2012.
