Plenty of people probably use toilets multiple times in a day. A large amount of precious water is flushed down the drain turning it into waste. According to a statistic provided by Conserve H2O, a Water Providers Consortium, 1.6 litres of water is wasted per flush. Depending on the toilet cistern parts, toilets can use even more water.
A home flush system uses up to 12 litres of water per minute. Plumbing experts say that in commercial buildings, 45 litres of water is utilized per day per employee. The huge amount of water wasted can be treated for drinking.
