Description of Technology

Descriptions for proprietary technologies are from the Massachusetts DEP Approval Letters for the technology.

The System is an alternative subsurface Soil Absorption System (SAS) that replaces a conventional SAS designed in accordance with 310 CMR 15.000. The System consists of an 11 5/8-inch diameter corrugated, high-density plastic pipe with a 9.5-inch interior diameter and a standard length per unit of 10 feet. The pipe is perforated with eight holes equally distributed around its inner circumference at each corrugation. Each hole has a plastic skimmer extending inwards. The exterior of the pipe has ridges on the peak of each corrugation and is wrapped with two layers of fabric material. The inner layer is a thick layer of coarse, randomly oriented polypropylene fibers. The outer fabric layer is a thinner non-woven geo-textile polypropylene. The System includes required connectors designed to connect pipe units together. The System also includes six inches of sand, specified as concrete sand meeting ASTM C-33 (also called ‘System sand’), surrounding the pipe on all sides.
