Raw Water Storage Impoundment (RWSI) approaches 80 percent completion
As shown in this image, approximately 80 percent of the Raw Water Storage Impoundment is complete. The RWSI is part of the environmental mitigation for the Savannah Harbor Expansion Project (SHEP) which will deepen the premier harbor in the state. The RWSI will hold raw water for short-term use by the City of Savannah water department in those rare occasions when low river flows coincide with very high tides pushing natural chlorides near the city's water intakes. The small reservoir will contain approximately two days of water. The extreme high tides last fewer than 12 hours. (U.S. Army Corps of Engineers photo.)
