5. Current Challenges Drinking Water Supply Issues Reclaimed Water Issues
Traditional groundwater supplies are limited and could ultimately limit growth
Non-potable water supply needs, such as irrigation, will also increase and could further impact the problem
Minimum Flow and Level on Indian Lake also a limiting factor
Access to reliable “non-traditional” water supplies requires significant capital and operating costs (ie: seawater)
Excess reclaimed water to Halifax River
In 2010, a portion of the Halifax River was designated an “Impaired Water Body”
A Total Maximum Daily Load (TMDL) was established and must be met by 2025
Potential Basin Management Action Plan (BMAP) in future will describe meeting TMDL
Identify more efficient use of the reclaimed water as a resource

6. PROJECT BACKGROUND $3.1M demonstration project
Full advanced treatment (FAT) technology
200,000 gpd
2-year demonstration period
The first demonstration scale potable reuse system in State of Florida
Start-up was October 2018

7. OBJECTIVES Provide Confidence and Reliability in Technologies
Collect Real Time Data from Treatment Processes
Provides Regulatory Agencies Water Quality Data
Promote Potable Reuse Education and Public Acceptance

9. Daytona Beach Preliminary Results
First round of microconstituent data
Almost nothing was found in permeate…clean really clean, water

10. Microconstituents Below HRLs
6.8 ng/l; HRL of 20,000 ng/l *
Non-Detects (Across the Treatment Process) - 17-a-ethynylestradiol
- 17-b-estradiol
- acetaminophen
- bisphenol A
- estrone
- progesterone
- testosterone
1.3 ng/l; caffeine in cup of coffee (1,600,000,000 ng/l)
6.2 ng/l ; HRL of 60,000 ng/l

11. What Does the Demonstration Facility Do?
Collects Trusted Technical Data to Show the Safety of Advanced Purified Water
Builds Community Confidence
& Connection
Advances the State of the Science
*All water from DTS facility is returned to the Westside Regional Water Reclamation Facility

17. The Future – Direct Potable Reuse
Demonstrate energy-efficient technologies that will create a safe and sustainable water supply extending the City’s use of existing sources.
Lower long-term operating costs
Guidance for regulatory framework
Provide public education opportunities including incorporating in AS2I

Tetra Tech IPR and RO project costs are in line with the WRRF report and much, much less than retrofitting neighborhoods to take reclaimed water; not cost effective, better to go with IPR or DPR 100% efficienc
