Yuck Factor Trumps Technology
- The main barrier to potable wastewater reuse is psychological 'yuck factor', not technology or safety.
- Even when water is thoroughly purified, people reject it if they believe it was once contaminated, as shown in a 2015 study cited by Regina Barber.
Windhoek's Decades Of Reuse
- Windhoek, Namibia has practiced potable reuse since the 1960s, showing long-term global precedent.
- International examples predate many U.S. efforts and demonstrate established operational experience.
Multistep Purification Workflow
- Potable reuse uses multiple barriers: microfiltration, reverse osmosis, UV with hydrogen peroxide, plus real-time contaminant monitoring.
- Reverse osmosis yields ultra-pure water that often has minerals re-added before distribution to protect pipes.
