Latrine Superstructures

Latrine superstructures used in emergencies vary enormously. Long term designs often involve bricks, concrete blocks, or any number of local building materials but these are generally unsuitable for the early phases of an emergency. Short term solutions currently used can involve plastic sheeting, wood or plastic panels. Oxfam are looking for a complete off the shelf solution for a pit latrine superstructure which can be installed quickly in the early stages of an emergency.

Design Criteria

Nature of solution A simple superstructure to give privacy to users using a pit latrine.
Durability The lifetime of the structure should be appropriate for the cost. Plastics should be UV resistant. The solution might also be reusable.
Size and shape Oxfam’s existing pit latrine slab is 1200 x 800mm. The solution should fit on the existing slab. A separate superstructure kit for disabled users may be produced.
Configuration The solution should be suitable for use with stand alone pit latrines and pit latrine blocks.
Privacy The solution should give the user complete privacy. The entrance should be lockable on the inside and, preferably, the outside as well. Note that thin plastic sheeting is often semi-opaque in strong sunlight.
Functionality The solution should have a pitched roof and provide ventilation (possibly through a gap between the walls and the roof). A vent pipe into the pit is not required.
Weight On arrival in the country, the solution will need to be man-handleable.
Packaging The solution should pack small for ease of shipping. Ideally, the solution will fit on an EUR-pallet.
Construction Method The solution should be quick and easy to use, requiring little or no skill.
Local Materials The solution should be a complete kit, not requiring any materials to be sourced in country.
Cost As a ballpark figure, £100 or less per unit.

Oxfam are able to present two options for the superstructure; one which is a rapid superstructure, which can be assembled in a matter of minutes and replaces the likes of plastic sheeting and wooden pole and a second one which is a more durable latrine. The following images present the concepts of the ‘rapid superstructure’ for the immediate scale up latrines in an emergency.
