Demand Projections - Action Item StatusStatus
1
Investigate population projections from stipulated settlement agreement between Sumter Co. and Wildwood - decide how to acknowledge in Water Supply Plan Update
SWFWMD still awaiting feedback from Wildwood/Sumter County on this.
2Hernando County Utilities wants their permits that are < 100,000 gpd broken out from the small utilities category
Completed; also see response to Item 3 below.
3Sumter County – separate out small public utilities in the utility listings
SWFWMD completed this and sent data for county and municipal permits. They can also break out projections for small private utilities, and will proceed with this as time allows. Still need confirmation from SJRWMD that they are willing / able to provide similar level of detail.
4 Engage private utilities in planning process Open
5 City of Ocala disagreed with per capita use numbers. Awaiting return call from Mr. Muse.
6The Villages - revise population and water demand projections to reflect no further increases after 2017
Completed and data was sent to commenter for review.
7 Incorrect name provided for private utility. Open
8
Wildwood and Bushnell are projected to have large commercial/industrial growth and are concerned that associated water demand is not included in their public supply projections
Comm/Ind demands to be served by public utilities are included in Pub. Supply Projections. The 2023 demands in Wildwood’s 10-year Water Supply Facilities Plan (3.62 mgd) are much less than those projected for Wildwood in 2025 by SWFWMD (6.31 mgd). Also, City's projected 2018 demands (2.87 mgd) are less than those projected by SWFWMD for 2015 (3.85 mgd).

Determining the Availability of Groundwater for Water Supply through 2035
Groundwater Availability will be Determined through the Use of the SWFWMD’s Northern District Model– A number of wellfields will be proposed in the vicinity of major
population centers with capacities large enough to meet projected demands.
– The production of the wellfields will be input into the model to determine how water resources such as wetlands, lakes, springs, and rivers in the vicinity of the wellfields will be impacted.
Determining the Availability of Groundwater for Water Supply through 2035
The model is being updated and expanded into the portion of Marion County in the SJRWMD
This will allow the use of a single model for the entire WRWSA Region.
Benefits of Using the Updated/Expanded Northern District Model– Greater degree of accuracy for evaluating impacts of groundwater
withdrawals– Information provided on the effects of groundwater withdrawals in
the Lower Floridan Aquifer
Model should be ready for use in July/August
Determining the Availability of Surface Water for Water Supply through 2035
Withlacoochee River (SWFWMD) Ocklawaha River (SJRWMD)
Determining the Availability of Surface Water for Water Supply through 2035
Withlacoochee River (SWFWMD)– The Upper and Middle Withlacoochee River minimum flows are
currently in draft form and scheduled for finalization in 2014– The Lower Withlacoochee River minimum flow is scheduled for
2014.
– Potential Withdrawal Locations• Croom
• Wysong
• Holder
• Lake Rousseau
Determining the Availability of Surface Water for Water Supply through 2035
Ocklawaha River (SJRWMD)– A minimum flow has been proposed for Ocklawaha River at SR-
40– Water could be available at confluence of Ocklawaha and Silver
River and at Rodman Reservoir– The SJRWMD has no formal recommendation for a water supply
project for the Ocklawaha River at this time– Potential annual average yield is being re-evaluated.

Conserve Florida Water Conservation Modeling Tool Online EZ Guide - Description
– SWFWMD requested that the Authority use the EZ Guide Model for the water supply plan update to assess the public water conservation potential for utilities through 2035.
– The model allows for detailed analyses of the water conservation potential for public water supply utilities.
– Data such as structure age, lot size, and property type (single family, multi-family, commercial) are input into the model, which calculates water savings based on age of plumbing fixtures, residential irrigation systems, and other factors.
– Model provides recommendations for implementing water conservation measures for specific water customer groups and the estimated water savings associated with each conservation measure
– Currently working out some problems with the model
Reclaimed Water Availability Assessment through 2035
Estimated quantity of reclaimed available in 2035 for all waste water treatment plants (flows > 100,000 gpd) that are not already accounted for by planned projects.
