ADVANCED WATER PURIFICATION SYSTEM Planning for the Future Speaker: Gary Jo Ann J. Macrina, PE Shannon Ponitz, PE www.codb.us October 26, 2018

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

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

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

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

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

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

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

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

First Barrier - Ultrafiltration (UF)

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.

Third Barrier – UV Disinfection with Advanced Oxidation Pure water

Operation and Testing a GO!

The Finished Product, an Advanced Purified Water of Superior Quality

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

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

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

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
