Water-Intensive Patterns of Development
37
County-wide Public Supply Per Capita Use
Rates

• Central and Southern Counties
• 5yr Average 114 gpd/c
• Ranges from 86 to 145 gpd/c
• Northern Counties
• 5yr Average 167 gpd/c
• Ranges from 146 to 172 gpd/c
• Note Per capita usage rates are affected by
  factors such as source substitution and the
  number of residents per household.

Northern Planning AreaWater Resource Conditions

• Resources are generally in good condition from a
  regional perspective
• High growth area with pattern of development that
  has trended toward high water demands
• Areas of concern have emerged
• Opportunity exists to develop a strategy to
  prevent local impacts from coalescing into a
  regional problem

What is a Water Use Caution Area (WUCA)?
48
What is a Water Use Caution Area?

• A WUCA is a region of the District where the
  Governing Board determines additional regulation
  is necessary to address water resource concerns

49
Declaring a WUCA

• ? A WUCA is based on a Governing Board
  determination that
• regional action is necessary to address
  cumulative water withdrawals.
• ? To address present or future
• adverse impacts to the water resources or the
  public interest.

50
Declaring a WUCA

• Purpose of a WUCA
• - to impose special requirements for
  existing water users and permit applicants.
• - to prevent or remedy specific problems.

51
Declaring a WUCA

• Considerations
• Water availability
• Water quality
• Impacts to wetlands
• Impacts to lake stages or surface water flows
• Impacts to land uses

52
Regulatory Components

• Regulations are developed case-by-case to address
  area-specific issues.
• Regulations are augmented by non-regulatory
  components.
• Regulations and non-regulatory approaches
  developed through a workgroup effort with
  stakeholders and interested persons from the
  affected area.

53
Regulatory Components

• EXAMPLE Northern Tampa Bay WUCA
• Issue Ground water withdrawals causing
  wetland and lake impacts.

Regulatory Components

• EXAMPLE Northern Tampa Bay WUCA
• Goal Reduce ground water pumpage
• Solutions
• ? Reduce water demand (conservation)
• ? Increase alternative sources
• - Reclaimed Water
• - Alternative Supplies (surface water,
  desalination)

57
Regulatory Components

• EXAMPLE Northern Tampa Bay WUCA
• Regulations developed
• ? Enhanced public supply water
  conservation requirements (e.g., rate
  structures, water audits)
• ? Enhanced irrigation efficiency
  requirements (agriculture, golf courses)
• ? Lowered threshold for metering of
  Permits (100,000 gpd rather than 500,000
  gpd)
• ? Reclaimed water requirements

58
Questions?
59
Non-Regulatory Approaches

• Inclusion in Regional Water Supply Plan
• Increased monitoring research
• Increased assistance with conservation, use of
  reclaimed water, water supply planning
  alternative development

60
Non-Regulatory Approaches(continued)

• Education
• Youth and Adult
• Indoor and Outdoor
• Messaging
• Watershed planning
• Assist local government water resource planning

61
Non-Regulatory Approaches(continued)

• Cost-share projects
• Alternative Water Sources
• Conservation
• Reuse of Reclaimed Water
• Research
• Resource assessments
• Irrigation needs of grasses crops
• Water saving devices

62
What do you think?

• Demands exceeding groundwater supplies
• Demands rapidly growing
• A need to be more efficient
• A need to develop alternative supplies
• A need to avoid impacts to the environment
• A need to prevent a recovery strategy

63
Next Steps

• Continue taking input until April 23
• Next workshop April 23 Sumter County
  Fairgrounds 6 p.m.
• Report back to Governing Board April 24
• Please make sure we have your email address
