The South Carolina Water Situation
South Carolina's Commercial Water Market Is Feeling Compounding Rate Pressure Statewide
South Carolina's commercial water customers face rate increases from multiple directions: Columbia and Rock Hill both raising rates in the same cycle, Spartanburg increasing water and sewer, and data center growth along the Charlotte-SC corridor straining supply and prompting infrastructure investment that all commercial customers fund.
Commercial properties in South Carolina may have site-specific water-system and billing considerations. Smart Valve™ assessment and installation planning is based on the property's actual setup, billing history, and local requirements. Published project results vary by site and measurement period.

Columbia: 8% in 2025 | Rock Hill: 5% FY2025
Columbia, South Carolina's capital, raised commercial water rates 8% in 2025. Rock Hill implemented a 5% increase in FY2025. These simultaneous increases in major SC markets reflect a statewide infrastructure investment cycle — utilities across South Carolina are aging and require substantial capital investment.
Spartanburg Water and Sewer Both Increasing
Spartanburg is raising both water and sewer rates, adding to South Carolina's multi-utility, multi-city rate increase landscape. For commercial properties with combined water and sewer billing, both line items are rising — compounding the overall cost impact for facilities in the Upstate SC region.
Data Centers and Drought Conditions Adding Supply Pressure
The Charlotte-SC data center corridor is growing rapidly, placing increasing demand on water resources in both the Piedmont and Coastal Plain regions. Combined with drought conditions affecting surface water availability, South Carolina's commercial water supply is under dual pressure that will continue to drive rate increases.
