Build a rain barrel in spring to collect and save water for the hotter days of summer. Rain barrels collect about 300 gallons of water for every one inch that falls on 500 square feet of roof. That’s 300 gallons less flowing as runoff picking up pollutants and instead promoting beautiful neighborhoods in later summer when it’s drier. Rain barrels are simple to construct with a 55 gallon barrel, a spigot and a few other small supplies.
