Content - Summary

Compared to many other developing countries, the official sanitation condition in Bangladesh is relatively good. The Government of Bangladesh (GOB) has declared to achieve 100% sanitation coverage over the country by 2013. As the main intention is to increase sanitation coverage, GOB is promoting the cheapest and easiest solution for sanitation, which is the pit latrine. As a country of flooding and high ground water table, pit latrines form a great threat for environment. The seepage causes ground water pollution causing people to suffer when using ground water for drinking purposes. Additionally, every year floods destroy many sanitation facilities and force people to resort to open defecation.
In the literature, UDDT is advised to be the most suitable option in flood-prone areas. There is also some evidence of implementing UDDT in flood-prone areas. However, upscaling UDDTs may lead to acceptance of users and to too high costs.
This study aimed to evaluate the suitability of UDDTs in flood-prone areas of Bangladesh. Furthermore, affordability of UDDT is also analyzed in this study. In addition, projection was made on potential contribution of human excreta to fertilizer demand for one case study area.
