¾ Reliability – especially

Stormwater Reuse
¾ Opportunities

¾ Developing statewide stormwater rule

Being “Drought Smart”
¾ Efficient
use during times of normal
rainfall allows recharge of surficial and
ground water resources.
¾ During times of water shortage, effective
conservation allows more users to share
limited resources.

18.7 million people, 4th largest state
¾ 2025

2060: More Water Use?
¾ In
2005
6.5 billion gallons per day.
6 Public water supply accounts for 37% of
use

2060: Reached Resource Limits?
¾
Even more areas with groundwater
withdrawal caps?
¾ Forced to decide among water use
sectors?
Water Resource Vision
¾
Even more reuse of reclaimed water:
6
6
6
Achieve close to 100% reuse statewide.
Potable quality water is not being used for
irrigation.
Reuse is valued as a resource -“Water is
Water”.
Water Resource Vision
¾
All utilities adopt water rates that:
6
6
6
Promote water conservation and
significant savings realized.
Promote reuse and its value as a
resource.
Adopt drought rates prior to crisis for
implementation as needed.
Water Resource Vision
¾ Low
impact development is the norm:
Florida Friendly Landscapes are always
installed and are socially and aesthetically
accepted.
6 Irrigation accomplished by properly installed,
high-efficiency equipment and/or climatebased controllers.
6 Stormwater reused on site.
6 BMPs routinely implemented.
• Green roofs installed
• Only pervious concrete used
6
Water Resource Vision
¾ Water
Conservation
Per capita goals established and met.
6 Water and energy efficient appliances
always used in new developments.
6 Older homes and businesses have been
retrofitted with efficient appliances.
6 Agricultural irrigation uses most efficient
methods.

Water Resource Vision
¾ Water
Supplies and Climate Change:
Impacts of climate change on water
management systems have been evaluated
and quantified.
6 Decisions to develop water resources
adequately incorporate a complete analysis
of effects of that development on climate
change.
6 Effects of climate change on water resources
minimized and mitigated.
6 Diverse water supplies are developed – no
one source meets all the needs.
