Operating and maintaining an island community’s water and wastewater systems

Seabrook Island is a private, barrier island community in South Carolina located 25 miles southeast of Charleston. It is a small island measuring seven square miles, made up of six square miles of land and one square mile of water. Seabrook Island is a large tourism spot with a total full time population of 1,819 people and over 1,649 housing units.

Challenge
The Seabrook Island Utility Commission (SIUC) is responsible for providing safe and reliable potable water and efficient and dependable sanitary sewer services to the Town of Seabrook Island. SIUC selected Louis Berger to provide turnkey operations for the community’s water and wastewater infrastructure, which at times must withstand coastal storm surges and heavy rains.

Solution
Louis Berger provides an on-site Operations Manager and skilled employees, licensed by the state’s Department of Health and Environmental Control, to operate and maintain all Seabrook Island water and sanitary sewer facilities. Physical facilities include the potable water distribution system (water storage tanks, pump stations, distribution lines and water meters) and the sanitary sewer system (collection lines, lift stations and a central waste water treatment plant). In addition, Louis Berger handles payments, budgeting, accounting, meter-reading, billing and collection services.

The original Seabrook Island water system was installed in 1971. Since starting turnkey operations in 1995, Louis Berger has helped introduce substantial improvements to the community’s water and wastewater systems, including:

  • A $1.7 million wastewater treatment plant upgrade and expansion in 2013 to provide a safer system of wastewater treatment, improve plant performance and protect public health.
  • A $2.0 million upgrade to the potable water storage and distribution system, adding two 500,000-gallon ground storage tanks, a high service pump station, 20,000 linear feet of 20-inch water main and 17,800 linear feet of 16-inch water main.
  • A $2.2 million project with FEMA to upgrade sewer pump stations.
