Kenya happens to be one of the countries in Africa that failed to achieve the millennium development goals on increasing the access to clean water and improved sanitation to her citizens. A third of Kenyans are the ones that access to improved sanitation and most of them are in the urban. The use of dry toilets which are the toilets that hygienically separate excreta from human contact. About 30 million Kenyans don’t have access to improved sanitation. Hence, they are still using rudimentary methods like latrines and almost 6 million Kenyans are defecating in open i.e in the bushes.
More and more environmentalists consider the use of dry toilets as the solution for solving the problems caused by the utilization of flush toilets. With the application of flush toilet, in addition to its harmful environmental effects and to the high water consumption of toilet, the nutrients in the human excreta are wasted.
The main objectives of this study were to get insights on the issue of low access to sanitation. Secondly to gather information and use it to develop affordable dry toilets as a form of achieving sustainable sanitation which is one of the key pillars of the sustainable development goals (SDGs).
The methods used in collection of the data were divided into two major parts that’s the primary and secondary data. Primary data was collected by physical visits to the site, interviewing the people in charge of the different institution manufacturing these types of toilets. i.e. the operation officer at Ecoloo group. The head teacher at the Kangemi Five Star Academy. Who outlined how the toilets worked and how they used the humanure. Secondary data was collected from the electronic media and the print media especially books, journals and internet sources.
The use of dry toilets has had a positive impact especially in the developed countries where it was initially adopted for use in the rural areas, but as time went by it was adopted in the urban areas.
The recommendation made from this study include that the alternative forms of toilets should be introduced in the schools syllabus, dependence on international aid to get the toilets should be discouraged, cheaper designs of the same toilets should be introduced to reduce the cost of installation and buying and this will encourage its adoption.
In conclusion dry toilets are a preferable means of human waste disposal both the solid waste and liquid waste. These toilets are safe and have no adverse effect on the environment thus they can be used as a sustainable form of sanitation in the third world countries to control the human waste
iii
menace in the peri urban settlements, informal settlements and in schools. The dry toilets saves the amount of water used in flushing toilets and also produces organic fertilizer as a product of the waste. Thus the dry toilets are a form of toilets that can be used in achieving sustainable sanitation.
