Citizens Energy Group (Citizens) is a utility company serving the residents of Indianapolis and surrounding counties. Citizens supplies water, wastewater, natural gas, chilled water, and steam to more than 850,000 people.

The White River North Water Treatment Plant (WRNWTP) is the third largest treatment plant in the Citizens Water System, which consistently provides up to 15 percent of the water demand in the metropolitan area. The plant and associated services area are located in Carmel, Indiana. Growing demand necessitates expansion of the White River North Water Treatment Plant (WRN WTP) from 34 million gallons per day (MGD) to 49 MGD. Citizens seeks support expanding certain unit processes in the WRN WTP to meet the treatment objective of 49 MGD.
