Smoothwall is very popular for sanitary leach field use because of its low cost, large perforations, and high beam strength when compared to singlewall perforated polyethylene pipe.
Beam strength is a measure of the stiffness of a pipe in the longitudinal direction. Because Smoothwall is relatively stiff in the longitudinal direction, it can easily be laid straight and "true to line and grade". Smoothwall pipe requires a stone backfill/envelope to allow it to function effectively for leach field applications.
