Residential Pilot
Location: University Park, IL
Pilot Partner: Aqua Illinois (local water utility)
Scope: 9 homes tested
8 of 9 homes saw lead drop well below EPA’s 15 ppb action level
In late 2018 and 2019, Aqua Illinois detected elevated lead levels in homes throughout University Park, sparking a “Do Not Consume” advisory and prompting residents to rely on bottled water for years. With mounting public distrust and growing legal pressures surrounding lead contamination, Aqua Illinois sought a scalable, effective residential solution—without resorting to bottle distribution or expensive home re-piping.
In 2020, Aqua Illinois selected Noah’s auto-flushing system for a 9-home pilot. Each home received a Noah device installed at the kitchen faucet. This pilot tested whether automated flushing could rapidly lower lead levels in a residential contex —with no filters, no infrastructure overhaul.
The outcomes were dramatic and conclusive:
Overall, Noah’s system produced substantial, consistent reductions in lead levels—demonstrating its effectiveness in typical residential plumbing
Capitalize on proven tech:
Residential success mirrors school results—orthophosphate protection works in both contexts
Deploy anywhere:
From large districts to single-family homes, automated flushing delivers rapid, accurate results.
Low overhead, high impact:
Minimal installation, no filters, no continuous labor—just reliable water quality.
