2. Current Challenges Drinking Water Supply Issues
Wastewater Effluent Disposal Issues
Limited groundwater supplies
Non-potable water supply needs, such as irrigation
Reliable “non-traditional” water supplies requires capital and operating costs (ie: seawater)
Total Maximum Daily Loads (TMDLs). Portion of Halifax River designated an “Impaired Water Body” in 2010
Future Basin Management Action Plan (BMAP) for restoration
Currently at 92% of water withdrawal allocation
Growth & Development
Climate Variation Issues
Increasing demands
Wet weather versus Drought

3. Multi-faceted Approach to Sustainable Water Resources
What Daytona Beach is doing NOW to ensure sustainable water supply
Limit Watering during Drought
Reclaimed Water
Wetlands Rehydration
Evaluating Potable Water Supplementation

4. Objectives More alternatives for reliable drinking water sources
Protecting our health
Protecting our environment
Collect Real Time Data from Treatment Processes
Assist Florida in development of a regulatory framework for potable reuse projects

5. A Trend Towards Alternative Water Supplies in the U.S.

6. Project Background
Demonstration scale advanced water purification system; $3M
Partner with St. Johns River Water Management District; $1M grant
Purified water test in real time for 2-year demonstration period

7. Construction Completed Mid-2018
Production capacity of 200,000 gpd (0.2 MGD)
Apply proven engineered advanced treatment technologies
Will comply with or exceed strict state and federal drinking water standards
Demonstrate high purification level

8. Multi-Barrier Treatment Train Process
Reclaimed (Reuse) Water
Available for Water Supply
Membrane (Ultra) Filtration
Reverse Osmosis
UV Disinfection / Advanced Oxidation

9. What should be in your drinking water and what should NOT?

10. First Barrier - Ultrafiltration (UF)

11. Second Barrier – Reverse Osmosis (RO)
Cl-
Note, that this capacity was selected because it is the minimum skid size for 2-stages using 8” membranes.

12. Third Barrier – UV Disinfection with Advanced Oxidation
Pure water

13. Operation and Testing a GO!

14. The Finished Product, an Advanced Purified Water of Superior Quality

15. What will the Demonstration Facility Do?
Collect Trusted Technical Data to Show the Safety of Advanced Purified Water
Build Community Confidence
& Connection
Advance the State of the Science
*All treated water will be returned to the headworks of the Westside Regional Water Reclamation Facility

16. A State-Approved Testing Protocol
Rigorous sampling plan, approved by Florida Department of Environmental Protection
Include testing for physical, mineral and inorganic constituents
Primary and secondary drinking water standards, including pathogens
Mutagenicity
Online analyzers for simplified operations, and real-time quality monitoring
On-site laboratory testing with specialized analysis by outside labs

17. A Rigorous Water Testing Program to Observe the Safety of the Approach
Pathogens
Bacteria
Protozoa
Cryptosporidium parvum (“Crypto”)
Giardia lamblia (“Giardia”)
Viruses
Chemicals
Primary and Secondary Drinking Water Standards
Salts (e.g. Sodium, chloride, potassium, sulfate, etc.)
Nutrients (Nitrogen, Phosphorus)
Disinfectants (e.g. chlorine) and Disinfection Byproducts
Personal Care Products
DEET (insect repellent)
Triclosan (antibacterial soap)
Pharmaceuticals
Atenolol (heart medication)
Azithromycin (antibiotic)
Naproxen (“Aleve”)
Fluoxetine (“Prozac”)
Other micro-constituents
Caffeine
Sucralose (“Splenda”)
Hormones

18. Benefits of Advanced Water Treatment
Preserve existing groundwater sources by minimizing further withdrawals, protecting the aquifer against seawater intrusion
Protect the coastal environment by reducing nutrient discharges to the Halifax River
Creates a locally-controlled, reliable supply of high quality water that is drought resilient
Uses one-third the energy required to desalinate seawater
Produces purified water that meets or exceeds state and federal drinking water standards
Secures a safe, sustainable, and affordable water supply for the future
