Palm Coast - The City of Palm Coast has completed the latest expansion of its southern wellfield - adding five deep wells that provide source water from the Upper Floridan Aquifer.

The new wells expand Palm Coast's southern wellfield, located south of State Road 100 between Interstate 95 and U.S. 1, over a larger geographic area. The City's allocation to withdraw water from the aquifer is not being increased. But the new wells will allow the existing wells to rest, be rotated and reduce production rates.

"That will lessen the possibility for saltwater intrusion because it reduces the amount of pumping needed from each location," said Palm Coast Utility Director Richard Adams. "Increasing the number of wells also maintains the sustainability of water supplies in Palm Coast and the entire region and protects natural systems such as wetlands."

The southern wellfield now has 13 deep wells, and the City plans to add three more over the next couple of years to complete that wellfield. The City also has a northern wellfield.

The $3.2 million southern wellfield project was supported by $932,250 in cost-share funding from the St. Johns River Water Management District. The contractor for the project was McMahan Construction, based in DeLand.

The southern wellfield provides source water for Palm Coast's Water Treatment Plant 2, one of three water treatment plants in the City. Water Treatment Plant 2 is home to the innovative Zero Liquid Discharge (ZLD) process, which allows the City to recover and treat nearly 100 percent of the water concentrate produced by the water plant, instead of discharging the concentrate into a nearby freshwater stream. The ZLD system saves millions of gallons of water each year and also eliminates the need to discharge the water concentrate into a nearby stream.

"This wellfield expansion is important to providing a safe and high-quality water supply for Palm Coast, and it's part of the St. Johns River Water Management District's 'sip, not suck' initiative," Adams said. "The City of Palm Coast appreciates the support of the Water Management District and is proud of the successful completion of this project for its benefits to our water system."
