“Harvesting Rainwater with Rain Barrels” can be viewed in the Dudley Hall Gallery Oct. 11-22. Collecting rainwater is an ancient and traditional practice, and dates as far back as 2,000 years ago. With the rising price of municipal water and with drought restrictions now facing many communities, more and more homeowners are turning to the harvesting of rainwater to save money and utilize this precious natural resource. Rain barrels are a simple way homeowners can store rooftop runoff for reuse for landscaping and other non-potable uses. The most common approach involves directing a roof downspout to a 55-gallon rain barrel. A hose is attached to a faucet at the bottom of the barrel and water is distributed by gravity pressure. Rain barrels are based on the Low Impact Development approach that treats rooftop runoff as a resource that should be reused or infiltrated. A drawing will be held Oct. 19 at 4 p.m. to give away the rain barrel on display. Sign-up is free. For more information, contact Charlene LeBleu at 844-0192 or leblecm@auburn.edu.
