Pennies From Heaven
Environmentally, there are numerous benefits to using rain barrels. Water collected in a rain barrel would otherwise run or drain off the roof and become stormwater runoff, which is problematic. When excess water is directed into storm-drains the streams that they feed into are subjected to sudden surges of water, causing erosion and flooding. Unlike treated water from your tap, rainwater is free of chlorine and chloramines, chemicals added to water to make it safe for human consumption. Rainwater is also free of salt, which can build up in the roots of your plants when they’re watered with tap water.
