In a single family residence above a floodplain but sitting on a lot of clay soil, heavy rains can cause severe drainage issues. I am investigating several systems/solutions, including dry well. On the "This Old House" remodel project in Cambridge in 2012 [season 32; episode 12], Roger and Kevin installed a dry well [after other(s) had been installed off-camera]. It was yellow plastic; open-bottom; weighed about 70 pounds; and held over 340 gallons - over 500 including the storage in the surrounding rocks. How can I find manufacturing/purchase information for that specific product or other reasonably priced components for someone in Austin, Texas?
