Abstract
A thermoplastic device for leaching sewage system effluent into the earth has the shape of an inverted trough. Its sidewalls have slot shaped perforations; above each slot is a lip; beneath each slot is one or more protuberances, preferably rectanguloid in shape. The combination of lips and protuberances prevent compaction of the earth against the sidewalls when the devices are buried without the use of stone fill. They permit the formation of a good biocrust layer and facilitate the exfiltration of liquid into the earth.
Claims17
A device for dispersing liquids within the earth, having the shape of an inverted trough;
- being arch shape in cross section, with the top of the device during use being at the top of the arch, and the base of the device during use being at the base end of the arch;
- having sidewalls with a multiplicity of perforations for the passage of liquids, characterized by perforations having lips vertically thereabove to shield the openings, and spaced apart protuberances therebelow to aid dispersion of liquids in the earth.
A conduit for dispersing liquids within the earth, having a sidewall with a multiplicity of perforations for the passage of liquids from the interior to the exterior thereof, characterized by perforations having both a lip protruding from the sidewall thereabove, to hinder infiltration of earth into the interior during use, and spaced apart protuberances therebelow, to hinder compaction of the earth below the protuberances.
