2019 FLORIDA WATER FORUM Potable Reuse Commission A status update and next steps

1. 2019 FLORIDA WATER FORUMPotable Reuse CommissionA status update and next steps Why Potable Reuse in Florida?

2. Why Potable Reuse for Florida • Florida’s Water Supply Challenge • Population in 2035 projected to be 25.2 million • Water Demand for 2035 projected to be 7.5 BGD • Public Supply Demand to increase 23% to 3.08 BGD • An additional 580 MGD needed to for Public Supply

3. Why Potable Reuse for Florida 67% of Florida is Designated a WRCA “Water, water everywhere but not a drop to drink” of inexpensive readily available groundwater Alternative Water Supplies to meet 2035 demands Central Florida Water Initiative (CFWI) Southern Water Use Caution Area (SWUCA) North Florida Regional Water Supply Planning Area

4. Why Potable Reuse for Florida • Reclaimed Water a potential Alternative Water Supply Resource • Total Wastewater Effluent Quantity = 1.68 BGD • Non-Potable Reclaimed Water Use = 812 MGD • Wastewater Effluent Not Reused = 787 MGD

5. Why Potable Reuse for Florida • Reuse as a Water Supply Resource • To supplement and diversify existing primary water supply • A resilient, consistent, and sustainable source • Largely Immune from climate impacts • Reduction in discharge benefits environment • Reduces competition for remaining groundwater supplies • Benefit to Agriculture by reducing competition for groundwater

6. Why Potable Reuse for Florida • Potable Reuse as a Potable Water Supply Resource • Technology and Research have demonstrated capacity to produce potable reuse protective of public health • Growing number of utilities implementing potable reuse • Western State utilities early adopters • Non-Arid State utilities adopting – Georgia and Virginia Examples • EPA, National Research Council, American Water Works Association, Water Environment Federation, National Water Research Institute, Water Research Foundation and Water Reuse Association endorse

7. Why Potable Reuse for Florida • Cost of Potable Reuse versus AWS Alternatives • Capital Cost competitive with Desalination, Brackish Groundwater, and some Surface Water sources • Energy costs less than or comparable to same AWS sources • Carbon footprint is less than many AWS sources • Recent innovations in Potable Reuse treatment alternatives is further lowering the cost – Altamonte Springs pureAlta • Cost = Key Factor in Evaluating Potable Reuse as an AWS

8. Why Potable Reuse for Florida • Public Acceptance Key to Successful Adoption • Endorsement and promotion by Regulatory Agencies, Industry and Professional Associations, International Research Organizations • Increasing public experience with potable reuse through growing number of utilities adopting • Focus of Utilities implementing potable reuse on developing public acceptance and support through outreach, open and transparent communication, and multiple education venues • Altamonte Springs • Clearwater

9. Why Potable Reuse for Florida • Potable Reuse is Not the “Silver Bullet” for AWS • Another “Tool in the Tool Box” for some utilities to consider • A supplement not the total supply • Reclaimed water as Potable or Non-Potable is a Water Resource • Integrated Water Supply Plan Establish “Fit for Purpose” • Adopt use that provides most value to Water Supply Plan • Primary considerations in Alternative Evaluation • Cost versus Alternatives • Public Acceptance – Governance through Customers
