Made Blue
Conservation Labs is the developer of an innovative, water-saving product: the H2know. Each H2know sold provides 1000 gallons of drinking water.

About Conservation Labs
H2know measures noise in water pipes per second, and uses patented technology and a machine learning approach to translate these signals into accurate water flow estimates, leak alerts and water insights.
This information is then displayed in the H2know app, making it easy to read. View reports, find leaks and discover ways to conserve water and save money!
“
Every time you do the dishes, flush the toilet, or use any water, the water rushes through the plumbing system to that location and creates a unique sound signature. You can hear it. H2know does too.

This is what the H2Know looks like when it is simply connected to the main water pipe of a building or house.

Choosing a selection of customers or donating more litres is also an option. Transparency is paramount and we are happy to help you communicate about it!
