The City's Water Treatment Facility was completed in 2008. It is located at 4000 Keslinger Road. The $24 million project was primarily financed with low-interest loans through the Illinois Environmental Protection Agency.
To meet the future needs of the community, an investment was made in the best municipal treatment technology available, reverse osmosis, which meets current drinking water standards as well as any future regulations.
Resident can learn about the history of the City's Water Treatment Plant online. Prior to 2008 deep and shallow well water was treated for iron and manganese, disinfected and sent to the distribution system with a very high hardness level. Now, roughly 85 percent of the deep and shallow well water is treated by reverse osmosis, with the other 15 percent blended in the final product to go into the distribution system.
The Water Treatment Facility produces final drinking water at a hardness of 5 to 7 grains, which allows residents, commercial accounts and industries to reduce or eliminate the need for additional treatment equipment like water softeners.
