We chose this challenge to try to stop wasting water and money.
In our college, it was found that 4 out of 16 toilets, one out of 9 urinal and 1 faucet leaking. We put marks on each toilet, urinal and tap dripping to report to the administration and to other students.
We made measurements and found a dripping tap wastes about 5m3 per year. The maintenance workers will try to repair the leaks. In 1 year, the cost of wasted water is about 16 € for 5m3.
