Collecting rainwater using rain barrels or other vessels is an ancient practice still used today. Rain barrels are an easy way to collect rainwater from your roof that can then be used to water your landscaping and gardens to save money on your water bill and provide water during drought times. Environmentally, rain barrels collect water that would ordinarily flow across your lawn picking up pesticides, sediment, and nutrients and carrying them to the local storm drains, then ultimately to rivers and streams. Rain barrels can often be purchased locally, or you can easily make your own.
