Fripp Island purchases treated water from the Beaufort-Jasper Water & Sewer Authority, which uses the Savannah River as its principal source. The District owns the water main that runs from St. Helena Island (near the Shrimp Shack), across the Harbor River, Harbor Island, Johnson Creek, Hunting Island and Fripp Inlet. Potable water is pumped into three elevated tanks on the island that provide 525,000 gallons storage. Water is distributed from these tanks to residential and commercial customers.
The District collects and treats all waste water generated on the island to reclaimed water standards and recycles the treated effluent for irrigation of the Ocean Point golf course. A new, state of the art technology treatment plant went on line in May 2006.
