A friend told me she saw a septic system install or rebuild done on one of the shows where instead of running 400-500 feet of perforated leach pipes, the leaching was done using plastic barrels of some sort.
Does anyone have a line on the manufacturer or a URL that describes this approach? I've got both a new house going in and an old farmhouse needing leach system replacement, and this sounds like a great alternative to hundreds of feet of trenching.
