The Joint Water & Sewer Commission has completed a major sewer line project on the north end of St. Simons Island that is critical to continue safely serving the existing customer base and to pave the way for future growth on that part of the island. To mark the project’s completion, the JWSC will host a Golden Valve Wrench event at 10:00 AM on Friday at the Dunbar Creek Treatment plant at 601 Palmetto Street.
