Why Harvest Rainwater
Each gallon of harvested rainwater equals a gallon of treated city water that can be put to better use. Harvesting rainwater saves municipalities money and, in turn, should reduce homeowners' water bills. Harvesting rainwater also helps reduce erosion and evaporation due to heavy rain runoff. Saving rainwater and distributing it more efficiently helps plant growth by washing salts down below plant roots the soil. It also helps feed more water into the water table, and keeps fertilizers and pesticides out of streams and groundwater.
