Abstract

The invention described herein includes a latrine pan and collector system for use in an offset pit latrine. The system permits use of a latrine pan having a flapper in an offset leach pit context, and eliminated the necessity of large scale installation of a concrete collection box, which can collect unsanitary debris. The system of the invention includes (1) a pour-flush latrine pan and (2) a collector. The collector includes a collector body that engages the latrine pan, defines a discharge opening, and secures an inclined surface sloping downwardly between an impact zone positioned beneath the outlet of the latrine pan and the discharge opening, the collector body securing the inclined surface at a position sufficiently distant from the underside of the latrine pan so that the inclined surface does not impede pivoting of the flapper, whereby material discharged from the outlet of the latrine pan contacts the inclined surface at the impact zone and slides downwardly from the impact zone to the discharge opening. Also included is the collector described above, related latrine structures and methods.
