Mission: Protection of natural resources and cost-effective, sustainable water supplies in the St. Johns River Water Management District through collaborative planning, scientific-tool development and other efforts.

The Central Springs/East Coast (CSEC) Regional Water Supply Plan (RWSP) area includes all or part of six counties in the St. Johns River Water Management District — Volusia, Lake, Marion, Brevard (excluding the city of Cocoa, which is included in the Central Florida Water Initiative CFWI), Indian River and Okeechobee counties.

This RWSP was developed through a collaborative process among the District, local governments, public supply utilities, environmental advocates, and other stakeholders for a 20-year planning period. The CSEC RWSP is based on the best data and research available. Key components of the CSEC RWSP include the groundwater flow models; the 2015 Volusia model, the Northern District Model Version 5, and the East-Central Florida Transient Expanded Model Version 1.0. These groundwater flow models incorporate elements of the water budget, including recharge, evapotranspiration, surface water flows, groundwater levels and water use.

Based on the results of the CSEC water resource assessment, the District determined fresh groundwater alone cannot supply the projected increase in water demand during the 20-year planning horizon without causing unacceptable impacts to water resources. The CSEC RWSP identifies solutions to meet the current and future water use needs of the region while ensuring the natural resources of the area are protected. The CSEC RWSP provides water resource and water supply development project options to guide water users and suppliers in their efforts to meet the projected water demands while protecting the region’s natural resources. Project options range from aquifer recharge and potable reuse to alternative water supply sources like reclaimed, surface water and stormwater.

Water supply planning is an ongoing process, with enhanced scientific methodologies and new data acquired regularly. the District is already working on the science and data collection for the CSEC RWSP five-year update. Through this process, the District has been able to create a roadmap that offers options to achieve sustainable water use through the planning horizon.

The Central Springs/East Coast (CSEC) planning area is one of three planning regions within the St. Johns River Water Management District. The CSEC planning area includes part or all of the following counties, Volusia, Marion, Lake, Brevard, Indian River, and Okeechobee.

RWSP workshops

The District held three public workshops to communicate the status, overall conceptual intent, and impacts of the Central Springs/East Coast Regional Water Supply Plan on existing and future reasonable-beneficial uses and related natural systems. Each workshop presented the same overall summary for the planning region. In addition, specific details pertaining to the sub-region in which the workshop was held (1 – Volusia County, 2 – Brevard, Indian River, and Okeechobee counties, and 3 – Marion and northern Lake counties) was presented.

Workshop 2
Wednesday, July 28, 2021 at 5:30 pm (for sub-region 2 – Brevard, Indian River, and Okeechobee counties)

Commission Chambers, Indian River County Administrative Complex, 1801 27th Street, Building A, Vero Beach, FL 32960

Workshop 3
Thursday, July 29, 2021 5:30 p.m. (for sub-region 3 – Marion and northern Lake counties)

2015 Volusia Model

The 2015 update to the Volusia Model was utilized to perform the water resource assessment and project sufficiency analysis in Volusia County of the CSEC RWSP.

Northern District Model Version 5

Marian, North Lake area map

The Northern District Model Version 5 (NDMv5) is a groundwater model that was developed collaboratively with the Southwest Florida Water Management District. The NDMv5 was utilized for the water resource assessment and project sufficiency analysis in Marion County and the northern, or non-Central Florida Water Initiative, portion of Lake County.

East Central Florida Transient Expanded Model Version 1.0

Broward, Indian River, Okeechobee area map

The East Central Florida Transient Expanded Model Version 1.0 (ECFTX) is a groundwater model that was developed collaboratively as part of the Central Florida Water Initiative. The ECFTX was utilized for the water resource assessment in Brevard and Indian River counties along with the small portion of Okeechobee County that falls within the jurisdiction of the district.

There are three MFLs prevention/recovery strategies in place within the CSEC planning region; the Volusia Prevention/Recovery Strategy (2013) and associated five-year assessment (2019), the Silver Springs Prevention Strategy (2017), and the Lake Butler Prevention Strategy (2020).

Water conservation is necessary to ensure sustainable water supplies and to help protect Florida’s waterways and natural systems. It is often the simplest and most cost-effective strategy that can involve all water users in the region. As such, water conservation is a critical component in the CSEC RWSP.
