Regional water supply planning, §373.709, F .S. The governing board of each water management district shall conduct water supply planning for a water supply planning region …, where it determines that existing sources of water are not adequate to supply water for all existing and future reasonable-beneficial uses and to sustain the water resources and related natural systems for the planning period. 7
What is a regional water supply plan (RWSP)? Constitutes an assessment of: • how much water needed over the planning horizon and • whether the traditional sources meet the demand While: • protecting the water resources and related natural systems and • identifying future water supply sources 8
RWSP process • 20-year planning horizon • Conducted in open public process • Identifies supply sources/water resource development projects to meet all reasonable- beneficial demands • Approved by Governing Board • Updated on a 5-year basis 9
Is a RWSP similar to a capital facilities plan? No – – WSPs focus on sustainability of resources – Point to or identify options for water supply, strategies, and AWS projects economic feasibility environmental feasibility technical feasibility 10
Are users required to implement RWSP options? No – • Water users are not required to implement any of the options identified • Users may offer one of these alternatives to mitigate impacts for new permits or when requesting increases in allocations 11
Will a RWSP affect consumptive (water) use permits? No – • This is a plan, not a regulatory requirement • The plan contains strategies – conservation concepts – essential to all water use permits – reclaimed water and AWS feasibility evaluations – lowest quality source 12
NFRWSP – planning process • NFSEG regional groundwater flow model • Water use and future projections • Water resource analysis • Water supply development and water resource development projects • Water conservation and reuse 13

The region’s challenge Estimate 667 mgd of water need at 2035 117 mgd potential Range of recovery needed by for the Lower 2035 Santa Fe and Ichetucknee MFLs 550 mgd in 2010 WRD projects are predicted to reduce withdrawal effects to priority water bodies. 17
Water resource analysis • Assessed the amount of fresh groundwater available to meet 2035 demands using NFSEG model • Determined impacts to water resources ‒ groundwater quality ‒ wetlands ‒ MFLs ‒ spring flows ‒ non-MFL priority water bodies 18
Analysis results determined that: • Traditional groundwater sources can meet some, but not all, projected water needs • Water demand projections exceed fresh groundwater availability • There are wells with elevated chlorides, and increasing chloride trends • There are springs and rivers below MFLs • There are potential impacts to non-MFL springs or other waterbodies 19

Surface water constraints 22
Proposed Water Resource Caution Area 23
Since constraints are not met • The plan identifies projects to meet future demands while meeting the needs of the water resources • The projects include a combination of water resource development, water supply development, conservation, reclaimed water or other projects • The total sum of projects exceeds the shortfall; these projects are identified to show that future demands can be met through a combination of alternatives 24
Opportunities and solutions • Water conservation • Recharge • Alternative water supply – Surface water – Stormwater harvesting – Reuse • Collaboration 25
Water conservation • Indoors • Outdoors • Rates • Education 26
2035 Low and high water conservation potential 27
Diversification of water supplies: Excess surface water or storm water 28
Reuse options Augmentation of surface waters used Landscape irrigation for irrigation Recharge Potable reuse Rebound (in feet) for 10 MGD Golf course irrigation injection 29

WSP Planning Pr WSP Planning Process ocess WMDs - Update WSP every five years After GB Approval 6 Months – WMD Notifies PWS of projects in WSP 12 Months – PWS selects project(s) and informs WMD 18 Months – Facilities Work Plan adopted into Comp Plan Then Thereafter Annually Nov. 15 – PWS submit Annual Report 33
Importance of collaboration • Meet needs of commercial, agricultural, environmental and urban uses • Meet needs of recreational and quality of life • Business and community leader engagement is vital • Working together to meet all the needs will ensure a vital economy 34
