The document describes a study conducted by students at a Greek elementary school to measure and reduce water consumption. Over three weeks, they recorded the water meter readings each morning and noon. They found that initial daily usage was about 1 cubic meter. Then they placed fire bricks in the toilet tanks, which reduced flushing volume. This lowered daily usage to 0.8 cubic meters, saving 0.2 cubic meters per day or 2 cubic meters per week. The students concluded that using a fire brick is an effective way to reduce water consumption and help the environment.

9. Conclusion
Measurements taken during the first week showed that
water consumption at our school was about 1m³ per day.
After placing the fire bricks in the toilet tank of our school
one can notice that water consumption at school was
reduced to 0,8 m³ of water per day. We managed to save
almost 0,2 m³ of water per day or 2m³ per week!
Placing a fire brick in the toilet tank is a good and clever way
to reduce water consumption!
Save water… Save the planet !!!
