One solution.
Built for everyone.
Our Mission:
Lead-Free Water for All.
At Noah, we believe in the universal right to lead-free drinking water. Access to safe drinking water is a fundamental human right, yet millions suffer from lead contamination daily. Noah's mission is to make lead-free, clean water accessible and affordable for every person on our shared planet.
OUR PARTNERS
The Problem Isn’t the Water Supply—It’s the Pipes That Carry It.
Despite municipal treatment efforts, harmful contaminants like lead and Legionella can still accumulate in building pipes—especially during periods of low use or stagnation.

What is Auto-Flushing and Why It Matters
Noah’s technology automates water movement to prevent stagnation that causes lead to leach from pipes and allows bacteria to grow.
- Keep water moving, even during building downtime
- Reduces risk of lead, Legionella, and copper
- Can be retrofitted to existing fixtures

Case study /
Safer water for
Chicago Public Schools
Our auto-flushing system isn’t theory—it’s proven.
In 5 Chicago Public Schools, Noah reduced lead levels to non-detectable, without filters or manual flushing.

Case study /
Scientific Validation: Orr High School Pilot with Loyola University
Read More About the CPS Pilot“Auto-flushing is a very economical and effective approach to mitigate lead in drinking water for outdated water infrastructure.”
- Dr. Zeinwei Zhu, Loyola University Chicago
At Orr High School, CPS partnered with Loyola University’s Institute of Environmental Sustainability to rigorously test Noah’s auto-flushing technology.
Over several months of third-party testing, lead levels dropped well below the Illinois action threshold—even after 6 days of water stagnation.
- 17 flushing units installed and monitored
- Lead levels held consistently under 5 ppb
- Maintained performance even during shutdown periods
Our Founder
In response to the Flint water crisis, Chief Engineer Michael Ramos took on a mission to ensure safe, affordable drinking water for millions. After elevated lead levels were discovered in a Chicago high school's drinking water, well beyond EPA limits, the school's Chief Engineer embarked on a journey that would inspire a groundbreaking solution.
FAQs
How does Noah help reduce lead in water?
Noah automatically flushes out stagnant water where lead and bacteria can build up. By keeping water moving, it prevents toxins from leaching into your pipes and helps maintain safe, clean drinking water.
Does it waste water—and increase my bill?
Not at all. Noah uses about 12 gallons per day—enough to prevent stagnation but very little in cost. In most cities, that’s less than $25 per year per unit.
What buildings or people is Noah designed for?
Noah is used in homes, schools, daycares, public buildings, and cities. Whether you're a parent, principal, facility manager, or municipal leader, Noah was built to protect your water at the source.
What makes Noah different from other water safety solutions?
Most solutions rely on filters, expensive reverse osmosis systems, or time consuming manual flushing. Noah is different—it uses smart, automated flushing to prevent lead and bacteria from building up in the first place. No filters, no maintenance, no guesswork.
