Info

The technology uses locally available materials (farm bricks, pit and river sand) with wire and cement also used for construction. This substructure and slab unit will provide service for 10 – 15 years From this beginning a large number of toilet options can be built – starting simple with the possibility of upgrading over time.
The uBVIP is built in three stages. Stage 1. The pit is lined with bricks and capped with a concrete slab. The slab is designed in such a way that this basic unit can be upgraded over time to a full VIP Stage 2. As a starting point, a low cost superstructure made from traditional materials (grass and poles) is erected around the slab to provide privacy. A slab extension is made to one side. Simple brick structures can also be built. Stage 3. Using the latest techniques, a durable brick spiral superstructure can be built with a light weight and durable roof and tubular vent fitted with corrosion resistant fly screen
