Advanced Drainage Systems™ SB2 Leach Bed Pipe
SB2 gravel-less leach bed pipe system can be a cost effective alternative to conventional leach beds. The piping is comprised of eight or ten inch Single Wall corrugated polyethylene pipe with uniquely located perforations wrapped with ADS Drain Guard® and non-woven geotextile.
The outside diameters of the pipe provide an infiltrative soil absorption area. The location of the drain holes (60 degrees off the bottom center line) provide equal distribution along the entire trench. The Drain Guard protective wrap is sonically welded to the corrugated pipe and allows free passage of effluent to the soil while limited soil particle infiltration.
