Water Harvesting Project at the San Antonio Food Bank
Water is our lifeblood and has been since the dawn of time. The birth of agriculture and urban settlement in the Fertile Crescent of the Middle East owed its viability to water.
The San Antonio Food Bank (SAFB) is fortunate to be the recipient of a Department of Energy Grant that provided two 65,000 gallon rainwater storage tanks that are designed to capture rainfall from one half of the SAFB warehouse roof and condensation from the refrigeration units. One inch of rain (when we get it) will generate approximately 31,000 gallons of water which will drain into tanks in the garden.
Upon completion of the project, the entire garden will be watered through a drip irrigation system fed by the rainwater harvesting system. Drip irrigation is the most efficient way to provide water to plants. The total amount of water needed to grow a crop is reduced, and the plant root system is more effectively watered using a drip system. Fertilizers can also be efficiently injected in to the drip irrigation system to maximize plant growth.
When completed, the rainwater harvesting project will continue to serve as an educational tool demonstrating an important method of water conservation that can be implemented on a broad scale. The project was a collaboration between the SAFB, Bexar County, the City of San Antonio and San Antonio Water System.
