What are the advantages of a rainwater collection system?

 

Each year, thousands of gallons of rainwater are wasted, flowing off roofs and into the ground.  A rainwater collection system allows you to use this valuable resource.  As San Antonio and the Texas Hill Country continue to grow, the Edwards Aquifer must provide for an increasing number of people.  A rainwater collection system helps ensure that you and your family will have access to water for years to come.  Rainwater is naturally soft and free of minerals, making it ideal for drinking water, bathing, and laundry.  Almost 40 billion gallons of water could be saved each year if 10% of the roof area in Texas were used for rainwater harvesting (estimated by the Texas Water Development Board).
