The Beaufort-Jasper Water and Sewer Authority’s (BJWSA) Hardeeville Water Reclamation Facility (HWRF) expansion project received the Institute for Sustainable Infrastructure (ISI) Envision Bronze award. The project is the first to win an Envision award in South Carolina.
The HWRF project provides wastewater service to the areas surrounding the Town of Hardeeville in Jasper County, SC. BJWSA will expand the facility to a rated capacity of 2.7 million gallons per day, with consideration given later to a second expansion to a 4-million-gallons-per-day capacity. And it includes new headworks, flow equalization basin, oxidation ditches, secondary clarifiers, disinfection chambers, and auxiliary structures.
“The Hardeeville Water Reclamation Facility will allow the area of Hardeeville to grow and keep the impact on the Savannah River minimal. The Savannah River recently reallocated demands[,] and having an efficient treatment facility in design helped BJWSA secure their needs for the future,” said Brian Chemsak, director of engineering for BJWSA.
Some of the sustainable practices that made the project worthy of an Envision designation included strong sustainable leadership from project owner BJWSA in targeting ways to extend the facility’s useful life. The design plans of improving site accessibility, safety, and wayfinding were realized through installation of additional signage, additional access points for emergency personnel, and enhanced security features.
Silt fencing, erosion and sediment control measures, seeding of disturbed areas, and stormwater diversion features were introduced to limit the effect on the natural environment in the surrounding area buffer zones.
The ISI Envision rating system measures sustainable infrastructure projects in five categories: quality of life, leadership, natural world, resource allocation, and climate and risk. Learn more about Envision and ISI at sustainableinfrastructure.org.
