Pennsylvania American Water on Thursday marked the completion of a $24 million upgrade to the company's Rock Run Water Treatment Plant near Coatesville intended to improve capacity, reliability and energy efficiency.
The upgrade expands the treatment capacity of the West Caln Township plant from 5 million gallons per day to 7 million gallons per day. The improvements also replaced aging equipment to ensure compliance with drinking-water regulations. The plant supplies about 12,000 custoemrs in western Chester County.
The project, which took more than two years to complete, received a $9.9 million low-interest loan from the Pennsylvania Infrastructure Investment Authority (PENNVEST).
