A major expansion of the Rocky River Regional Wastewater Treatment Plant remains on schedule for completion next fall, increasing the facility’s capacity to handle wastewater as Cabarrus County and the surrounding region continue to grow.
The Water and Sewer Authority of Cabarrus County (WSACC) announced that construction on the fourth phase of the expansion is progressing as planned, with completion anticipated in fall 2027.
The project will increase the plant’s wastewater treatment capacity from 30 million to 34 million gallons per day, a roughly 13% increase intended to accommodate continued residential and commercial growth throughout the region.
