WATER QUALITY ADVISORY: ReWa crews restoring operations following sewer overflow


Wednesday, May 31, 2023

Renewable Water Resources (ReWa) crews have restored operations following a sanitary sewer overflow (SSO) that was identified late Wednesday afternoon within the I-385 corridor along Gilder Creek in the Mauldin area.

The proper notifications were made to the South Carolina Department of Health and Environmental Control (SCDHEC), in addition to any downstream water intakes downstream of the reported overflow. ReWa officials said the SSO stopped at approximately 4:30 p.m., a little more than an hour after crews were notified of the issue at 3:13 p.m.

Wednesday’s SSO resulted from a break in the Gilder Creek Gravity Main, a 15-inch line. ReWa’s collections team was able to move quickly to ensure bypass operations were in place to redirect flows from the damaged pipe. An investigation is underway to determine the cause of the line break and calculate the volume of the loss.

This event will NOT affect ReWa’s ability to provide sewer service to the area and will also NOT affect the drinking water. Pending further review, ReWa will continue to post updates regarding progress and new details as they become available.

For additional information, please contact our hotline at (864) 299-4004. Any updates will be posted as a “news alert” at the top of our homepage at www.ReWaonline.org.
