Moses, 24, Kenya - Dunga wetland faces a myriad of problems i.e. habitat destruction, pollution, hunting among others. Limited land space undermines any efforts put by conservation bodies to try and protect the swamp. Farming is one of the ever increasing threats to the wetland that continues to pose a detrimental effect on its biodiversity.

This project idea centers mainly on setting up of ecological sanitation toilets for the collection of manure. The toilet uses the principle of anaerobic respiration where the collection vault is tightly fit to exempt any water or moisture from mixing with the waste.

Every time that the toilet is used wood-ash is spread as a treatment. This is used to ensure dryness and make the area not conducive for any micro-organisms. EM (Effective Micro-organism) can then be added as a further treatment. When the vault is full it is tightly sealed and left for 6 months while the other is opened for use. There is another vault for collection of urine which is mixed with water in the ratio of 5:1. The urine can be used ONLY on Fruit tree roots to improve the “greenness” of the leaves, and also kill certain pests.
