GSWSA History

A young boy and girl enjoy a drink of fresh water.History

In the early 1970's, our founders saw the need for clean, potable water and sewer services in the rapidly developing non-municipal area east of the Intracoastal Waterway in Horry County. This vision included a comprehensive and coordinated water and sewer utility system that would allow Horry County to develop its full potential.

This sense of purpose led to a modern success story, the Grand Strand Water and Sewer Authority. From a utility with no assets, customers, or funding, in fifty years GSWSA has grown into a company with assets over 805,000,000, approximately 96,000 customers, and annual revenues over $124,000,000.

From a limited service area east of the Intracoastal Waterway, the Authority has expanded to provide services from the North Carolina line to parts of Georgetown County, and rural areas west of the Waccamaw River. In a county known as the 'Independent Republic', we provide contractual services to six of the county's municipal water and sewer utilities and two public water companies. The development of the GSWSA has been instrumental in Horry County's growth from a population of 70,000 in 1970 to over 332,651 today.


We're here to provide the best possible water and sewer services to the residents, visitors and businesses within our service area. We're also here to protect the public health, protect the environment, and improve each of our customers' quality of life.


The vision of the Grand Strand Water and Sewer Authority is to have water and sewer services available to all areas of Horry County, to be the preferred provider of water and sewer services in the County, and to be the regional leader in quality and cost of water and sewer products and services.

  • A modern success story with approximately 96,000 customers and $805,000,000 in assets.
  • Committed to the public health, environment and our customers’ quality of life.
  • The vision to be the regional leader in quality water service.
  • Providing a full range of water related services to unincorporated areas of the eastern Carolinas.
  • Working closely with developers, contractors and engineers to ensure continued well-planned infrastructure for our communities.
