City of Savannah I&D Water Treatment Plant Immediate Systems Improvement Project (Phase I)
Savannah, GA
The Coastal Georgia Regional Water Partnership is a landmark, multi-jurisdictional initiative supported by $501.7 million in state funding to modernize and expand water supply infrastructure serving the Savannah region. Through collaboration between the City of Savannah, Bryan County, and Effingham County, the program is structured as a long-range, phased investment in water treatment, transmission, and system resiliency to support sustained regional growth through mid-century.
At the center of this effort is the City of Savannah’s Industrial & Domestic (I&D) Water Treatment Plant, which draws surface water from Abercorn Creek to serve regional industries, municipalities, and commercial and residential customers across the rapidly growing coastal Georgia area. With system demand now exceeding the plant’s existing 58 MGD permitted capacity—and with groundwater withdrawal limits increasing reliance on surface-water sources—the City has initiated a phased capital improvements program to incrementally expand treatment capacity and supporting infrastructure.
The Phase I I&D Water Treatment Plant Immediate Systems Improvement Project (2025) represents the current design and delivery effort and is focused on expanding firm treatment capacity from 58 MGD to 65.2 MGD, with construction completion anticipated in 2027. Delivered using a Construction Manager at Risk (CMAR) approach in partnership with Garney Construction, Phase I provides critical near-term improvements needed to meet projected 2025 demands of 65.2 MGD (Maximum Day) and 74.2 MGD (Peak Hour). The Phase I effort is supported by $146 million in state funding and is structured to address immediate capacity constraints while laying the groundwork for future expansion.
