Thus, three positive invert elevations can be set for an inlet pipe for a particular article: a first and second at each limit of rotation of the adapter, and a third and lowermost elevation, wherein the adapter is not used.

A latch comprises a tang which cantilevers outwardly from the top of the dome end, to engage a catch which is a flared portion of lip on the overlapping plain end.

Abstract: Rain water is drained from a golf course sand bunker or like structure by a drainage system which comprises a conduit having a solid top and perforations in the sidewall. A conduit which is a chamber having an arch shape cross section is contained within a sand filled trench running along the bottom of a bunker. Water flows downwardly from the bunker into the trench, passing through opposing side trapezoid cross section spaces which are defined between the outwardly angled chamber sidewalls and the essentially vertical trench sidewalls. The water then flows horizontally into the conduit. Geotextile, in combination with downward sloping louvers which define slot perforations in the chamber sidewalls, hinders flow of sand into the interior of the chamber. The arch shape of the preferred conduit frees the trench bottom of vertical soil-compressive load and enables it to be fully exposed for water penetration.

Abstract: A continuous curve arch shape cross section leaching chamber made of molded thermoplastic has closely spaced corrugations and sidewalls which are perforated with slots which slope downwardly, running from interior to exterior of the chamber.

Slotted wall thickness is less than about two times the thickness of the basic chamber wall thickness elsewhere. The chamber has properties and performance approximating prior art chambers, but has substantially less normalized weight and total weight.
