Our History

We’ve been replenishing the lakes, streams and rivers of Upstate South Carolina since 1925. Our rich history demonstrates the dedication and forward-thinking innovation of ReWa leadership and staff to enhancing quality of life in our region through responsible and sustainable wastewater treatment practices.




As Greenville began to grow, the Greater Greenville Sewer District was created to improve environmental sanitary conditions.



The Federal Water Pollution Act was passed.



The Clean Water Act established the basic structure for regulating pollutant discharges into the waters of the United States.



Greater Greenville Sewer District is renamed to Western Carolina Regional Sewer Authority.



The invention of the Dechlorination Process allowed for the removal of chlorine before water was diffused into local waterways.



We launched the ReWa Biosolids Program to enhance local crop production by improving soil fertility.



The Roundtable was established to evaluate and plan for the future by developing a 20-year strategic plan to align regional wastewater infrastructure with projected area growth while promoting environmental sustainability.




We introduced cutting-edge technology into our water treatment process by using ultraviolet disinfection and deep bed sand filters.



Western Sewer Authority is changed to the name we have today - Renewable Water Resources (ReWa).



We launched the Be Freshwater Friendly and Project Rx programs to educate the Upstate community on the impact of day-to-day decisions in water protection and preservation.



We’re recognized as the first Wastewater Utility in South Carolina to be accepted into the Environmental Management System for the ReWa Biosolids Program and the 33rd agency in the United States certified for this recognition.



We collaborated with the City and County of Greenville to form the Reedy River Water Quality Group to proactively address water nutrient pollution.



Greenville Health System (now Prisma Health) partnered with us to provide Project Rx 24/7 medication drop boxes at multiple locations within the Upstate.



We began our first tunnel project, DIG Greenville, designed to improve wastewater infrastructure in Greenville for the next 100 years.



We opened our state-of-the-art laboratory facility with interactive educational exhibits on environmental and wastewater treatment processes.



Our comprehensive 5-year strategic plan was released outlining our organization’s growth plan and vision for the future.
