The Chatham Park Decentralized Water Resource Recovery Facility (WRRF) supports the initial stages of North Village, a 2,224-acre mixed-use village that is part of the $15-billion master planned community known as Chatham Park. North Village utilizes water sustainability practices, offers walking and biking trails, employs lighting techniques to mitigate impact on the night sky, and makes use of green building techniques.
The WRRF provides beneficial reuse-quality effluent and is part of North Village’s water supply sustainability system. The 250,000-gpd facility, consisting of two parallel 125,000-gpd treatment trains, is expandable to 1.0 mgd with additional parallel trains. Effluent is discharged to the Town of Pittsboro discharge location via a new effluent pump station and forcemain. As the need for reclaimed water increases, a chlorination disinfection system will be activated to meet Type 2 reclaimed water standards.
Through design-build delivery, McKim & Creed provided permitting, engineering procurement and construction services for the WRRF. The facility includes headworks, an influent pump station, a membrane biological reactor (MBR) system, a UV disinfection system, an effluent pump station, a reclaimed water storage and pump station, a waste-activated sludge aerobic digester, chemical feed systems and odor control. Engineering services furnished by McKim & Creed included civil, site/civil, mechanical (HVAC), structural and electrical engineering, as well as instrumentation and controls.
The project is currently in construction and is scheduled for completion in 2019.
