This project was under a very tight schedule due to the fact that DRH Cambridge Homes absolutely had to close and occupy homes by August 1, 2005. The site and concrete work proceeded throughout the winter to meet the tight schedule. After breaking ground, the wastewater treatment plant was completed in 7½ months and the water treatment plant in 8½ months.

The 1 million gallons per day wastewater treatment plant includes a control building, influent screen building, aerobic digester, two clarifiers, oxidation ditch, sand filter building, and sludge storage pad. The treated water will be stored in a 35-acre lagoon and used for irrigation of surrounding areas. This is the largest zero-discharge wastewater treatment plant in the state of Illinois. The water treatment plant consists of a 1,400 gallons per minute ion exchange facility and two deep wells.
