Community-Based Waste-Water Treatment in International Development

A project, funded by PhD scholarships from the Islamic Development Bank and EPSRC (via the Doctoral Training Grants) is underway looking at the efficiency of meso-scale waste stabilization ponds to treat municipal waste water, with resource recovery from fish farming and selling sludge for fertilizer. The ultimate aim is to demonstrate systems that can be adpoted and run by communities, particularly in urban West Africa. The pilot project is based in Cotonou, Benin.

In the first stage of the work, Sena Peace Hounkpe Wendeou has investigated the treatment efficiency of the pond with and without macrophytes (plants), as well as conducting a survey into the existing state of sanitation in Contonou. In the second phase, Adrian Mallory will be using sociological methods to investigate the feasibility of engaging with local communities to install and operate small-scale waste water treatment and to benefit from the resource recovery potential.
