The Central Springs/East Coast (CSEC) Regional Water Supply Plan (RWSP) supports the protection of natural resources and sustainable water supplies in the St. Johns River Water Management District. The plan addresses projected water demands through 2040 and identifies water supply and resource development projects and conservation strategies to meet future needs while preserving environmental integrity.

The planning region includes all or part of six counties: Volusia, Brevard, Indian River, Lake, Marion, and Okeechobee. It encompasses three sub-regions: Marion and north Lake counties; Volusia County; and Brevard, Indian River, and Okeechobee counties. The region is home to six Outstanding Florida Springs and features the headwaters of the St. Johns River, the Indian River Lagoon, and over 140 miles of Atlantic coastline.

The St. Johns District is working in partnership with local utilities, communities, the Southwest and South Florida water management districts, the Florida Department of Environmental Protection (DEP), the Withlacoochee Regional Water Supply Authority, and other stakeholders. This collaborative, data-driven, and proactive approach ensures effective and consistent water resource and supply planning and development.

The CSEC RWSP was approved by the St. Johns River Water Management District Governing Board on February 8, 2022.
