Wastewater Treatment Plant

The Town of Mooresville operates the Rocky River Waste Water Treatment Plant (WWTP) at 639 Johnson Dairy Road. This plant is rated by the State of North Carolina to treat 7.5 million gallons of waste water per day. The water received into the facility is treated and discharged to Rocky River via Dye Creek. The sludge removed from the waste water is sent to our bio-solids facility where it is thoroughly dried by our advanced bio-solids dryer and sold as a soil supplement for agricultural purposes.

Functions of Waste Water Treatment Plant
The WWTP maintains a modern lab facility where we ensure the effectiveness of our waste water treatment and the cleanliness of the water we discharge. Our lab staff performs numerous tests every day to ensure we meet the high standards passed down to us from the Environmental Protection Agency.

WWTP also employs a detailed SCADA (Supervisory Control and Data Acquisition) system. This computer monitoring system has sensors throughout the plant and allows the plant operator to monitor the facility from one control room. The operator can then adjust waste water flows, make chemical changes along with monitoring pH, temperature and many other attributes.

The town’s Fats, Oils and Grease (FOG) and Pre-Treatment Staff also work out of this facility.
