According to Circle of Blue, a leader in reporting, research, and analysis on resource issues, your bathroom accounts for the highest percentage of home water use. The percentage is almost 75% - and 40% of that is from the toilet alone. Water conservation begins at home.
Older toilets are far less efficient than they are now so if the toilets in your home are older models, chances are you’re using a lot of water unnecessarily. By replacing old toilets with one of the High Efficiency Toilets (HET), you can cut home water usage by more than 25%.
