Rainwater harvesting includes rain barrels and cisterns. Rain barrels are water collection units that you can put on the outside of your home or garage that collect stormwater from your gutter system.
Cisterns are similar to rain barrels in that they can collect water from the gutters on your roof and can also hold grey water from inside and outside of your home (shower water, laundry water, but not toilet water).
