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

SLIDE 8

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

slide-9
SLIDE 9

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

slide-10
SLIDE 10

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

slide-11
SLIDE 11

Are users required to implement RWSP options?

No –

  • Water users are not required to implement any
  • f the options identified
  • Users may offer one of these alternatives to

mitigate impacts for new permits or when requesting increases in allocations

11

slide-12
SLIDE 12

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

The region’s challenge

WRD projects are predicted to reduce withdrawal effects to priority water bodies.

Estimate 667 mgd of water need at 2035 550 mgd in 2010 Range of recovery for the Lower Santa Fe and Ichetucknee MFLs 117 mgd potential needed by 2035

slide-18
SLIDE 18

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

slide-19
SLIDE 19

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

Proposed Water Resource Caution Area

slide-24
SLIDE 24

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

  • ther 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

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
