Severe to extreme drought conditions continue across the Lowcountry region of South Carolina, with rising temperatures and little rain in the forecast. Charleston Water System, which provides water to multiple communities, is already seeing an increase in water demand, up from an average of 64 million gallons per day to around 75 million gallons. While there are no immediate concerns about the water supply, officials warn that a prolonged stretch of hot, dry weather could strain the system and potentially lead to water restrictions.

Why it matters

The Lowcountry region, including Charleston, is heavily reliant on the Lake Marion Mulfrey watershed system, which covers 10 million acres. Prolonged drought conditions could put a significant strain on this critical water source, potentially leading to water shortages and the need for conservation measures that could impact residents and businesses.

The details

Charleston Water System communications manager Mike Saia said the utility is already feeling the effects of the dry, hot weather, with water demand increasing in recent days. The system normally averages around 64 million gallons of treated water per day, but that number has now risen to about 75 million gallons. Despite the uptick in usage, Saia said there is currently no need for water restrictions, but a prolonged stretch of upper 90-degree temperatures combined with little to no rain could begin to strain the water system.

  • Charleston Water System has seen an uptick in water usage in recent days.
  • The Lowcountry region has been experiencing severe to extreme drought conditions.

What they’re saying

“Drought is here. The warmer temperatures are here. And we're certainly feeling it in Charleston Water System.”

— Mike Saia, Communications Manager, Charleston Water System

“We're seeing a little bit of an uptick in use. We average about 64 million gallons a day of treated water going out to the community. And now we're up to about 75.”

— Mike Saia, Communications Manager, Charleston Water System

What’s next

Charleston Water System officials will continue to monitor the drought conditions and water usage, and may consider implementing water restrictions if the situation worsens.

The takeaway

The Lowcountry's reliance on the Lake Marion Mulfrey watershed system makes the region particularly vulnerable to prolonged drought conditions. While there are no immediate concerns about water supply, the uptick in usage is a concerning sign that could lead to the need for conservation measures if the dry, hot weather persists.
