The German Cooperation, GTZ in Collaboration with the Regional Centre for Hygiene and Potable Water, CREPA and the Douala City Council, CUD, have organised a workshop in Douala on Waste water disposals. The workshop was centred on three themes, reclamation, procedure of implementation and individual and collective hygiene. The workshop is also in line with the Douala City Council's drive on Urban Hygiene and development.

Speaking during the seminar, experts from the Douala City Council and CREPA tried to sensitise the participants on a low cost project on waste water disposal, which they believe could be beneficial. The aim was to satisfy the need of the population, no matter the social class. The experts sought to explain that waste can be treated such that the people benefit from it rather to suffer from the effects. By this it was said waste like faeces and urine can be treated in a way that it is not disposed in the river Wouri but can be treated so that it is beneficiary to humans.

Toilets must be built such that it has a soak away which will separate urine from faeces and when the soak away is full it can easily be evacuated and the faeces taken to a treatment centre which is found in Bois de singe in Douala. When it is treated it could become useful for farmers, to use as mature. The expert explained that when it is thrown in the sea after treatment it contain less toxic and cannot be harmful to the human system.

It was remarked that the treatment centre at Bois de singe is too small and so the Douala City Council is trying to create other treatment centres in Bone 10 and Bonamoussadi. The council expert explained the council has built a few public toilets which are operational around the town and also explained the plans of building more in the rest of Douala.

CREPA has a number of projects in West and Central Africa to build toilets which are durable, secured and good for the population which will reduce illnesses because the public would not have to mess around in streets and other corners but will use the toilets so that use can be better treated. Local water treatment plant is also part of the project.
