Demand management update
• Reviewing best management practice data
to ensure contains most appropriate
default values (work begins in May)
• Will initiate analysis once data is entered
into the LTDFS database (work begins in

evaluate different types of implementation
strategies.
• Efforts to be completed in 2017
Water Shortage Mitigation
Plan Update
• Initiated re-development of 2009 WSMP
- Goal: slow demand supply needs by
increasing ability to use additional GW
during water shortage period
• Discussed at recent Member Government
roundtable
• Forming technical team with MG
representation
• Met with SWFWMD
• Work being completed in-house with
anticipated completion by April 2017
Future Water Supply Options
• Small Footprint Reverse
Osmosis
• Seawater Desalination
Expansion
• Gulf Coast Desalination
• Additional Groundwater
From Existing Wellfields
• Thonotosassa Wells
• Surface Water Expansion
• Aquifer Recharge Project
• Potable Reuse
