One of our most recent projects, the South Carolina Highway 11 Sewer, exemplifies our client focused, innovative, thoughtful approach to conveyance system design. This conveyance project includes gravity sewer, two pump stations, and forcemain. The project was originally conceived to provide sewer service to the new $54M Walhalla High School. During our preliminary basin planning efforts, it quickly became apparent that this project could provide wastewater collection to a much larger and rapidly growing area of Oconee County for a nominal increase in project cost. Design South was instrumental in helping develop collaborative and cooperative relationships between multiple jurisdictions, including the School District of Oconee County, Oconee County, Oconee County Regional Joint Sewer Commission, and the City of Walhalla. In addition to the original sewer service for the new high school, the project will now provide sewer availability to 2,000 acres including 3.5 miles of highway frontage where sewer was previously not available. The project also included U.S. Army Corps of Engineers nationwide permit for several water crossings and a $500,000 Appalacian Regional Commission (ARC) Grant.
