MWH Constructors built a new $42.4 million wastewater treatment plant to help the Saluda River meet new water quality standards. The new plant consolidated four 50+ year old treatment facilities – Pelzer, West Pelzer, Piedmont, and Grove Creek—which had outfalls on the Saluda River and were taken out of commission upon the launch of the new regional facility.

Renewable Water Resources (ReWa) chose to utilize membrane bioreactor technology, allowing the treatment process to remove a higher level of nutrients, specifically phosphorus and nitrogen. The Piedmont Regional WWTP is the largest of its kind to use this type of technology in the state of South Carolina.
