Our sump pump drains into our back yard about 10 to 12 feet from our foundation. The backyard is flat so it takes some time to percolate in to the soil. I was wondering if anyone has had any success with a dry well to collect water while it seeps into the soil. If this will work I am also interested in a general size and construction (i.e. is 2.5 feet in diameter and 5 feet deep filled with gravel sufficient?)Help on this topic would be appreciated.Thank You, Chris Seabeck
