We were asked a question about rain barrels, and Jim Kleinwachter with the Conservation Foundation provided an answer.
Question: During a heavy rain a rain barrel's diverter can't handle the excess water and it overflows. Can you recommend a model or refer me to someone who is satisfied with what they have purchased?
Answer: Our rain barrels are repurposed olive/pickle barrels. They are easily adapted for larger overflow, and we have an upgraded model that comes with a large overflow (size of sump pump hose). We also carry an Aquascape model that is larger (75 gallon) and has a large overflow pipe built in the center. We also carry a special downspout diverter that will send water down the downspout when the barrel is full.
