Abstract
A low-profile arch-shaped wastewater leaching chamber having asymmetric corrugations running transversely along the length of the chamber, where each corrugation has a wide section with a straight sidewall on one side, a substantially flat top portion, and a tapering downward extending curved section on the opposed side of the chamber. Each corrugation is reversed in orientation and transversely offset relative to adjacent corrugations, such that the curved tapering section of each corrugation is significantly inset from adjacent wide sections toward the center of the chamber body.
Claims22
A leaching chamber for use with an onsite wastewater management system, comprising:
- (a) a chamber body with a central axis and a generally arch-shaped cross section extending between opposite side bases thereof, said chamber body including a plurality of corrugations extending transversely between said opposite side bases;
- (b) each of said corrugations having a first transverse side section with a substantially straight sidewall extending upwardly from one of said side bases to a substantially flat top portion, and a second transverse side section with a curved sidewall extending from said top portion downward to said side base on said opposite side of said chamber body;
- (c) said first side section and said second side section of each of said corrugations being reversed in orientation relative to that of an adjacent said corrugation;
- (d) said chamber body having a corrugation major span-width representing the shortest distance between axial tangential lines of a pair of reversed said first side sections at opposing said side bases;
- (e) said chamber body having a corrugation minor span-width representing the shortest distance between axial tangential lines of a pair of reversed said second side sections at opposing said side bases;
- and
- (f) a corrugation span-width ratio between said corrugation minor span-width and said corrugation major span-width being within the range of approximately 0.30-0.70.

A leaching chamber for use with an onsite wastewater management system, comprising:
- (a) an elongated generally arch-shaped chamber body having a plurality of corrugations positioned along the length thereof, said corrugations extending transversely relative to a central longitudinal axis of said chamber body between a base on a first side of said chamber body and a base on an opposite second side of said chamber body;
- (b) a first corrugation of said plurality of corrugations having a substantially straight sidewall section extending upwardly from said base on said first side of said chamber body to a substantially flat top portion thereof, and a curved sidewall section extending from said top portion downward to said base on said opposite second side of said chamber body;
- (c) a second corrugation of said plurality of corrugations adjacent to said first corrugation having a substantially straight sidewall section extending upwardly from said base on said second side of said chamber body to a substantially flat top portion thereof, and a curved sidewall section extending from said top portion downward to said base on said first side of said chamber body;
- (d) said substantially straight sidewall section of said first corrugation and said second corrugation including a plurality of substantially horizontal slots extending therethrough from an exterior of said chamber body to an interior thereof to allow wastewater to flow through said chamber body;
- and
- (e) said flat top portion of said first corrugation and said second corrugation transitioning to said curved sidewall section thereof at a point closely adjacent said central longitudinal axis of said chamber body.

- (c) a second corrugation of said plurality of corrugations adjacent to said first corrugation having a substantially straight sidewall section extending upwardly from said base on said second side of said chamber body to a substantially flat horizontal top portion thereof, and a tapering sidewall section extending from said top portion downward to said base on said first side of said chamber body;
- (d) said substantially straight sidewall section of said first corrugation and said second corrugation including a plurality of substantially horizontal slots extending therethrough from an exterior of said chamber body to an interior thereof to allow wastewater to flow through said chamber body;
- (e) a maximum height of said chamber body being about one-third or less a maximum width of said chamber body;
- and
- (f) an outermost transverse point of said tapering sidewall section of said second corrugation being inset from an outermost transverse point of said straight sidewall section of said first corrugation a distance falling within an approximate range of 18.0-54.0 percent of a largest total transverse dimension of said second corrugation.
