Quick Facts

The PSD At-a-Glance

  • Serves more than 19,000 customers in the north- and mid-island areas.
  • Provides an average of 6 million gallons of water per day.
  • Experiences a peak demand of 11 million gallons of water a day in the summer.
  • Provides water from three different sources:
    • Reverse Osmosis (RO) Water Treatment Facility on Jenkins Island treats brackish groundwater from the 600-foot-deep Middle Floridan Aquifer. The RO plant provides 3 million gallons of fresh water a day and is expandable to provide 6 million gallons a day.
    • Treated Savannah River surface water is purchased wholesale from the Beaufort-Jasper Water & Sewer Authority and is delivered to the island via a large pipeline underneath the Intracoastal Waterway.
      • Treated Savannah River surface water also is stored in the PSD’s Aquifer Storage & Recovery (ASR) Well inside Hilton Head Plantation. The ASR well stores the treated water during the winter months of low demand and withdraws it for retreatment and distribution during the summer months of higher demand, when wholesale water rates are more expensive. The ASR well provides 2 million gallons of water a day during the summer months.
    • Wells in the 150-foot-deep fresh water Upper Floridan Aquifer. These wells are the island’s traditional source of water but are being lost to the phenomenon of saltwater intrusion into the fresh water aquifer.
