Designed by Oxfam's WASH (Water, Sanitation and Hygiene) team, circa 2000, in collaboration with manufacturing partner K.K. Nag Pvt. Ltd, in India, this self-supporting latrine slab was considered to be revolutionary at the time and has subsequently been adopted by aid agencies across the world.

MoDiP’s example is manufactured by Dunster House (Bedford, UK), Oxfam’s current official supplier. It is rotationally moulded in high density polyethylene (HDPE), thin and lightweight to allow for efficient stacking in order to reduce shipping costs and ease user handling. It is also very tough and strong, reinforced so that it can be placed over a trench or pit without the need for additional support from below.
Efficient stacking and lightweight.

It has a key-hole shaped lid with a small lip that can be opened and closed with the foot, ensuring minimal contact, engraved with a 'Wash your hands' symbol to promote good hygiene.

There are raised, non-slip foot plates to keep the user elevated from draining fluids and the material is less permeable to chemicals and moisture with an easy-clean, low maintenance finish. Ready to use, it is easy to install and can be adapted to incorporate a pour flush if sufficient quantities of local water are available.
superstructures need to consider both local materials and cultural preferences.|

Intended as a temporary toilet during the first phase of an emergency, to be housed within a superstructure for privacy, security and dignity (refer image above), one slab is recommended per 50 people, gradually reducing to 20 people per latrine over time.
