We all live in a watershed. When it rains, that water runs off into our lakes, rivers, and streams, or percolates down into our aquifer. All the water we use that comes from the aquifer, which is a finite amount. We need to take measures to protect it. One way to do that is to install a rain barrel!
The benefits of a rain barrel include:
Reduces need for irrigation from well or municipal source
Saves YOU money
Rain can be better for the more sensitive plants like orchids
Provides water during droughts
Improves local water quality
Reduces rain runoff including pollution and flooding
