Project description:

It is all too common for people to walk away while waiting for the shower, bath or sink to warm up. In the time that we spend away from the faucet, the water has warmed up and continues to run for a period of time before we actually begin using it.

Litre Smart Water System is a solution to the passive hot water waste that occurs during the water warm-up period. In the U.S. alone, up to 360 billion gallons of hot water are passively wasted. This is entirely preventable with Litre’s technology.

What makes it smart / innovative?:

Litre Smart Water System’s patented technology prevents passive water and energy waste during the water warm-up period by monitoring water temperature and pausing the flow as soon as the desired temperature is reached.

The temperature is displayed on the device along with a corresponding color, visually letting the user know that the water is ready.

A pleasant chime on the device alerts the user that the water has paused and the water is ready for use. The desired temperature can be set manually or through voice command. This technology can correspond with an app that also provides alerts to the user, if desired.

Why is it relevant for the final user?:

Drought and water insecurity is a global reality. Litre Smart Water System provides users with a way to do their part to prevent passive water waste while saving on their water and energy bills.
