Taking A Closer Look

Kiawah Island
When South Street Partners, owners of the world-renowned development on Kiawah Island, sought to sell the water and wastewater treatment utility that serves the resort island, it had several goals: a fair price, strong customer service, the highest possible retention of existing employees, and the construction of a second water supply line for safety and redundancy.
SouthWest Water Company met every objective, retaining 100% of the utility’s workforce, upgrading customer service with credit card payment and online account management, and expeditious construction of a $10 million pipeline that runs more than 7,000 feet under a tidal estuary connecting to the mainland. Mission accomplished.
