Year: 2018

Chesterfield County owns and operates two wastewater treatment facilities with a combined permitted capacity to treat 39 million gallons of wastewater per day. As with all municipal wastewater treatment facilities, it is a continuous challenge to provide safe, environmentally- friendly and cost-effective treatment. One component of that treatment cost is wastewater conveyance from homes, industries, and business to the treatment works. Inflow and Infiltration (I&I) causes this cost to increase and consumes treatment capacity at the wastewater treatment plants. The Inflow an Infiltration Reduction Program developed a systematic approach to assisting in monitoring and reducing I&I, thereby providing safe and cost-effective conveyance of wastewater. Most importantly, the program maximizes the existing treatment capacity of the wastewater treatment plants, postponing costly upgrades and saving existing rate payers on their utility bill.
