Put your gutters to use! All that water from your gutters can be collected and stored in a water storage tank. Rainwater tanks are an easy way to capture rain for later use. By storing the rainwater in a tank or barrel, you will be able to water your garden or lawn without worrying about watering restrictions. Rain barrels are also know as water storage tanks, cisterns, and storage drums.
Many areas around the world use water storage tanks as their only water source. Big cisterns collect and store the water which is then filtered and used by residents. This collection and storage of water is a great way to conserve.
