Hilton Head PSD in March hosted officials from the Town of Edisto Beach on a tour of the PSD's Reverse Osmosis Plant and our new Aquifer Storage & Recovery well. Edisto Beach is faced with a significant saltwater intrusion problem in its drinking water supply wells and is considering Reverse Osmosis (RO) as a solution. The PSD's RO Plant has been providing 3 million gallons of fresh drinking water a day since the spring of 2009. It is a key tool in the PSD's ongoing work to replace drinking water supply lost to saltwater intrusion in our traditional groundwater source, the Upper Floridan Aquifer. In the photo above PSD General Manager Richard Cyr, second from left, discusses the operation of the Aquifer Storage & Recovery (ASR) well, which stores water in the underground aquifer during the winter months of low demand, and withdraws it during the summer when demand increases. Below, the group tours the RO Plant.
