Plainfield Department of Corrections
Town of Plainfield
An update to the Department of Corrections (DOC) Plainfield Facility’s existing sanitary sewer system was in need. The existing sanitary sewer collection system consisted of over 17,000 feet of sewers and much of the system was over 100 years old. The outdated system caused wet weather overflows and unnecessary treatment of stormwater at the wastewater treatment plant as a result of excessive infiltration and inflow. The project included over 7,000 feet of cured-in-place pipe lining, 16,500 feet of sanitary sewer reconstruction, and the elimination of an existing lift station.
The project was completed under the Indiana Guaranteed Savings Contract statute and was completed using the State Revolving Fund. The project was completed using a collaborative team effort, which was essential to success as the project was designed and constructed in an active prison setting.
This Guaranteed Savings Contract paid for itself, saving approximately $500,000 annually by eliminating 600,000 gallons per day of inflow and infiltration during wet weather from the Town’s sanitary system.
