Conserving water can be done in so many ways and using the Waterpebble from Priestmagoode. The green feature of the Waterpebble does not end with saving water from the shower, but also, the waterpebble is designed to be recyclable. The waterpebble works like a water meter that is equipped with a series of LEDS as the water volume indicator. You will see the red LED lighting if your consuming too much, orange for an average consumption, and green if you have saved enough water. Every time the user uses the waterpebble, the device will give earlier warnings, thus encouraging the users to shorter shower times and eventually save water.
