Kenya’s slum and majority of rural population defecates in the open and this can aptly be called the “big open toilet of Kenya”. Few toilets in the urban slum and rural areas are connected to the sewerage system; sewage from the rest flows in open drains, causing contamination of ground as well as river water, as per 2009 Census. This has serious health implications and is consequently a big economic burden. The picture below illustrates a Domestic Bio-toilet;
