PWC also implements a water reuse program at the two water reclamation facilities. The treated water produced from each plant is used to irrigate approximately 40 acres of landscaped turf at the two facilities. The recycled water is also utilized for in-plant uses such as seal water, cleaning of equipment, and for various plant processes.
PWC Farm (Residuals Management)
PWC is putting waste to work. Under a state-monitored Land Application Program, PWC recycled biosolids are at work on over 3,700 acres of local farmland, including PWC’s 750-acre farm in eastern Cumberland County. The land application program also extends into other counties, including Robeson, Hoke, and Harnett.
The recycling process has several components:
- The stabilized biosolids generated by both water reclamation facilities are transported by large tanker trucks to various permitted farm sites. All site conditions must be met before any application can occur.
- Specialized equipment at the farm sites evenly distributes the biosolids either by subsurface or surface application.
- The biosolids are applied at agronomic rates, the nitrogen rate required by the crop, so crops can uptake the proper amount of fertilizer found in the biosolids to grow such crops as corn, soybeans, sorghum, coastal bermuda grass and small grains.
- Row crops are harvested and sold to grain markets for livestock feed while grasses are sold to the public as feed for livestock.
- Research and compliance inspections by state regulatory agencies have shown this process to be a beneficial and environmentally friendly way to recycle biosolids. PWC has been performing recycling of biosolids from its water reclamation facilities since 1987.
Over the FY2015, the PWC farm produced 154 round (1,000 lbs.) bales and 123 square bales of bermuda hay and 8,251 bushels of soybeans.
