US 6,461,078 B1 · Plastic sewage pipe

Abstract

Systems for leaching liquid waste, particularly waste water. More particularly a cylindrical conduit or pipe for use in leaching systems. The pipe further has axially directed cuts or apertures in conduit/pipe valleys, has ridges, channels and grooves over which may be laid either single or multiple layers of fabric. The corrugated pipe may have slots or slits or V-grooves in and on the various portions of the pipe such as the outer-facing surface of the ridges, the end portion of the ridges, the side wall of the groove or through the bottom portion of the groove, i.e., the valleys. The cylindrical conduit disperses moisture away from the conduit through capillary action, wicking into a surrounding material. A perforated cylindrical conduit is one method permitting wicking. The surrounding material provides capillary action to transmit moisture away from the cylinder or conduit. These surrounding materials include sand, gravel, plastic fibers, wood products, slag, and ash. A fabric or other material may surround the cylindrical conduit. For septic systems, this includes any gravel-less systems such as the SB2, Environ-Septic® and Geo-Flow® systems. Other applications of this invention include treatment of oil-contaminated water and chemically contaminated water, in addition to septic tank effluent.
