Save drinkingwater by reusing your rainwater!

On this site you can see how much drinking water YOU could save by collecting and reusing rainwater on your property! You don’t need a large storage tank to save lots of water, a small rainwater tank that fills quickly during a rain event can save you considerable volumes of water over time.

Enter your roof area and how large a tank you would like and how you intend to use your water in the fields below. You can decide what level of detail that is most suitable for your project, and you can choose to use default values if you do not have all the information.
