Coverage and sustainability, however, still remain major challenges. The problems related to sanitation vary between urban and rural areas and among different geographical regions of Bangladesh. Considering the drawbacks of current sanitation technologies (with respect to varying local conditions), Practical Action Bangladesh has started working on eco-toilet and piloting since 2006. With financial support from UNICEF and DPHE, Practical Action Bangladesh and its PNGOs implemented an Action Research Project on Ecological sanitation in difficult areas (urban slums, Hoar, Hilly, Barind track and flood prone) of Bangladesh. Costing of the technology is another challenge for scaling-up. The average cost of conventional eco-san option is relatively expensive for the poorer section of the population. In this regard the current action research adopted a variety of options to bring down the cost. A number of design problems of the traditional eco-toilet and several modifications in the design of the have been made in order to improve the quality of compost and end uses. The research has also attempted to address another challenge, which of bringing about behaviour changes with respect to the use of eco- toilet. Because of the short duration of the project, it was not possible to demonstrate all the design options in particular for urban slums and areas with a high water table. The project attracted considerable attention to sanitation practitioners in order to address the ecological sanitation solutions for the difficult areas of Bangladesh.
