The wastewater group is a subset of the Water Quality Division.

The Wastewater Treatment Plant (WWTP) receives wastewater from the City of Fishers Sanitary Sewer District. Wastewater is conveyed through increasingly larger pipes and lift stations until it reaches the Cheeney Creek Wastewater Treatment Facility on Eller Road.  The Cheeney Creek Wastewater Treatment Facility is classified as a 10-million-gallons-a-day (MGD) facility. The Wastewater team is responsible for:  

  • Treating over 2.5 billion gallons of wastewater annually  
  • Fats, Oils, and Grease (FOG) management, a service for restaurants and bars to ensure proper collection and disposal of FOG materials 
  • Annual sanitary sewer cleaning of 110 miles of sewer pipe 
  • Sump Pump Disconnection Program – Sump pumps cannot be connected to sanitary sewer lines 
  • Manage capital improvement projects for extensive upgrades and improvements to address an aging system, expand capacity, and meet new regulatory requirements. 
  • Televising and inspecting over 39 miles of sanitary sewer  

Fishers Utilities manages more than thirty facilities throughout the community that collect, distribute, and treat sewer before releasing clean, safe water back into the White River.  

Wastewater Collection & Conveyance Facilities 

The City of Fishers has separate sanitary and stormwater collection and conveyance systems. Residential and commercial wastewater leaves houses and buildings via the building connections to the 8-inch diameter mainline sewers running under the streets or backyards. Wastewater is conveyed through increasingly larger diameter pipes to neighborhood lift stations. From there the wastewater is conveyed to larger regional lift stations, then to the Cheeney Creek Wastewater Treatment Facility. 

Wastewater Treatment Facilities 

The wastewater treatment facilities feature preliminary treatment, primary sedimentation, activated sludge, nitrification, secondary clarification, disinfection, and effluent re-aeration. Biosolids stabilization is via the N-Viro Soil process.
