Installing a rain barrel may be one of the most practical methods for homeowners to conserve water and possibly save valuable landscape plant materials.
Even with ample summer rainfall, evaporation occurs quickly with high temperatures, requiring supplemental irrigation.
An inch of rainfall on a 1,000-square-foot roof surface is capable of producing more than 620 gallons of water. Even a small shower will fill a barrel, saving valuable landscape plants or helping preserve a well with weak gallons per minute.
Cooperative Extension will offer rain barrels again this spring.
