McKim & Creed provided engineering services for a new potable water supply and treatment facility that complies with the State of North Carolina Central Coastal Plain Capacity Use Area (CCPCUA) regulations; allows the fragile Black Creek aquifer to adequately recharge; and enables the county to continue providing high-quality, great-tasting water at one of the lowest rates in Eastern North Carolina.
Established in 2002, the CCPCUA rules limited the amount of water that could be extracted from the popular Cretaceous aquifers that, due to the amount of raw water withdrawals, were unable to recharge sufficiently. At that time, Craven County received the majority of its raw water from these aquifers. The State mandated that withdrawals be reduced by 25 percent every five years until, by 2018, withdrawals would be reduced by 75 percent.
Castle Hayne is the most productive aquifer in North Carolina, but its water contains high concentrations of minerals, salt and iron. To make it suitable for drinking, bathing and washing, raw water from the Castle Hayne aquifer requires more treatment than water from the Black Creek aquifer.
To provide this treatment, the Craven County Water Department implemented the Potable Water Supply and Treatment Facility project. Opened in October 2017, the plant and raw water facilities produce up to 3 million gallons of fresh drinking water every day. As more people move to the area, the facility can be expanded to produce up to 5 million gallons per day. And it enabled the county to meet CCPCUA requirements well in advance of the August 2018 deadline.
During Hurricane Florence in 2018, portions of Craven County received 30 inches of rain and experienced catastrophic flooding. The plant remained in operation via emergency generators at each production well site as well as the treatment site. Craven County water customers were never without drinking water during the storm.
