Did you know just one inch of rain yields 650 gallons per every 1,000 square feet of roof space? Solana Center, in partnership with the San Diego County Water Authority, has brought back the discounted rain barrel program for San Diego County residents. Not only do rain barrels conserve precious water, they help protect our watershed and oceans by reducing urban water runoff, which is a major source of ocean pollution. The 50-gallon rain barrels are made of 100 percent recycled material and come with all the parts to start catching water now.
