Harvesting rainwater for residential applications is becoming increasingly popular as water bills increase and freshwater sources grow in scarcity. Given that each American uses an average of 88 gallons of freshwater each day, finding and utilizing alternative sources of water for potable and non-potable purposes will soon be essential. Rainwater is one of the best options since it’s free, helps to conserve freshwater for future generations, and can be utilized in the vast majority of cases where municipal water is used.
