Wastewater Treatment Plant

Learn More About the Wastewater Treatment Plant, it's History, Operations and the People who make it happen.

In October of 1972, the United States Congress passed amendments to the Water Pollution Control Act which required communities to upgrade wastewater treatment facilities.  The City of Niles received approval to upgrade their wastewater treatment plant, separate some of the City’s combined sewer systems, and construct a new interceptor sewer.  Sewer separation work was started in 1976 and substantially completed by the end of 1978.  Construction of the wastewater treatment plant was completed in the summer of 1979.  The total cost of this upgrade was approximately $33,200,000 with this cost being shared between the United States Environmental Protection Agency and the City of Niles.  The City’s $5,200,000 cost was financed through a 20 year bond that was paid off in 1998.

The City has a wastewater treatment plant with an average capacity of 5.8 million gallons per day, of which the City and Townships use approximately 3.0 million gallons.  This gives the City a reserve capacity of 2.0 million gallons per day.  In addition, the City is aggressively involved in a CSO program to separate portions of its combined sewer system.  During the summer of 2004, the entire downtown area was separated at a cost of $750,000. 

After ore than 40 years of operation the City’s wastewater treatment infrastructure has aged significantly.  Operation and maintenance costs have increased greatly and the Michigan Department of Environmental Quality (MDEQ) has raised questions regarding certain Plant processes and the plant’s ability to meet its National Pollutant Discharge Elimination System (NPDES) permit.  As a result, the City partnered with a consultant engineering firm to conduct a Master Plan study of the City’s entire wastewater collection and treatment system.  The wastewater treatment plant has had several components upgraded and other  components that continue to be part of the treatment process.  A coordinated program involving both the collection and treatment infrastructure will allow the City to respond to the issues of the MDEQ.

In 2011 the City of Niles Utilities Department completed a major upgrade to the wastewater treatment plant.  The upgrade included new influent pumps, a sodium hypochlorite disinfection system and sludge screw presses.
