Joint Regional Sewer


The Joint Regional Sewer System is comprised of interconnections between the Saluda County Water & Sewer Authority, Edgefield County Water & Sewer Authority, and the City of North Augusta wastewater collection systems functioning as a joint venture to provide sewer service to each member’s customers. Saluda County funded the cost of constructing a pump station at the Johnston Plant that interconnects a 16 inch sewer sewer force main that runs from Saluda County to the Johnston Plant, then parallel with S.C. Highway 121 to the Pine House Pump Station in Trenton. The Joint Regional Sewer System was constructed with funding from the U.S. Department of Agriculture’s Rural Economic and Community Development Program and has been in service for over ten years. The overall goal of the system was to boost economic development in the areas served by the Joint Regional Sewer System by providing a means of collection and disposal of higher strength waste streams typical of those found in industrial type discharges. The system consists of over 37 miles of force main ranging in size from 8 inch to 18 inch mains and has numerous pump stations. The major contributors are:

  • Amick Farms – SCWSA
  • Gentry Poultry – SCWSA
  • Carolina By-Products / Valley Proteins – SCWSA
  • Town of Ridge Spring – SCWSA
  • Saluda Middle and High School – SCWSA
  • King Academy – SCWSA
  • JET Middle School – ECWSA
  • Pine Ridge Subdivision – ECWSA
  • Town of Trenton – ECWSA
  • Federal Prison – ECWSA
  • State Corrections – ECWSA

Various other commercial, industrial and residential customers are also served by the Joint Regional Sewer System. The present allocated capacity for the Saluda County Water & Sewer Authority is 900,000 GPD and the present allocated capacity for the Edgefield County Water & Sewer Authority is 400,000 GPD. The Joint Regional Sewer System flows from the Edgefield County Water & Sewer Authority’s service area into the North Augusta’s service area collection system. Collected wastewater in the North Augusta system flows by gravity through several manholes into the Willow Wick Pump Station, located along West Martintown Road. Wastewater is then pumped into the Southwest Interceptor gravity collection basin. Wastewater flow then proceeds from the North Augusta collection system the Aiken County Public Service Authority’s Horse Creek Wastewater Treatment Plant for treatment and ultimate disposal. North Augusta and Edgefield County Water & Sewer Authority are in the process of designing a gravity sewer line with the purpose of eliminating the need for pump stations to serve the Joint Regional Sewer System in the North Augusta Service area.

The Authority and the City of North Augusta have constructed an expansion to the Regional Sewer System which increased the Authority’s sewer capacity by 2.3 MGD in the North Augusta System. The Authority’s share of the project cost was $2,600,000, funded entirely by an EPA grant.
