Community for Human Development (Lusaka, Zambia):Affordable Sanitation Solutions
The project focuses on two areas: provision of safe drinking water and adequate sanitation technologies. The student can choose to work on one or both.
Water: Many of the villages have bore holes (water points drilled – water extracted using hand pumps). In the villages which do not have bore holes people are forced to drink from unprotected (shallow) wells. What is required is a simple and affordable method of purifying the water at a household or village level.
Sanitation: Currently, the most widely used method of sanitation is that of pit latrines. Unfortunately, these are not properly constructed (e.g. lack or wrong shape), which means they rarely last longer than two years) Some Ventilated Improved Pit (VIP) latrines are used but these are very expensive to construct. Research is required into more appropriate, affordable sanitation solutions wither by improving the current pit design or investigating alternative solutions. There will also be a need for education and sensitisation of the community.
