The table above shows the amount of water saved by our team in one month

In this project, we inserted bottles filled with pebbles and sand in the cisterns of our school. It uses the displacement method, by which less water is flushed, which is saving around 2O percent of water usage. Within three months only we saved approximately 67,080 liters of water.  By this method, we are not only preventing water wastage but also reducing the water carbon footprint.
