overall water consumption

Water Battle is a serious game, bundled with a mobile app, that encourages households to change the way they use and consume water. The goal of the product is to reduce peak level water load. This result in less water usage, less energy used to transport water and a lower CO2 footprint.


A Game and an App

This serious game is played by children. They help little creatures survive in a world that’s threatened by water. Children earn points by playing the game and finishing levels. Parents in connected households play along by using a mobile app, that is connected to a smart water meter in their home. By adjusting their daily water consumption routines, they too can earn points, accelerating their children’s progress. Working together they learn about sustainable water usage, earn more points and win the Water Battle.
