I'm in the middle of a garage renovation and driveway install. I just laid drainage pipe to connect a downspout to a dry well. Originally, I was going to use a 55 gallon drum, but I'm not sure where to get one locally.
Home Depot has this:
NDS 24 in. Plastic Storm Water Leaching System-FWAS24 at The Home Depot
When I asked a local drainage supply company, they only had huge drywells. They instead recommended a biodiffuser:

The biodiffuser is technically designed for sewage but hit holds 120 gallons when the other container holds 55 gallons. Is one of these products going to work better than the other?
