The ancient practice of collecting and storing rainwater is growing in popularity because it helps conserve water by reducing the demand on our potable water supply, conserves existing water resources, diverts water from municipal storm drain systems and protects the ocean from storm run-off pollution. The rain water collected is ideal for plants and vegetable gardens. Many may question the use of rain barrels in our coastal desert climate. However, if you flip that argument, it makes even more sense to collect as much rainwater as possible just because water is such a scarce resource. For every inch of rain falling on a 1,000 square foot roof, 600 gallons of water can be collected.
