The principal objective of this document is to assess the scaling-up-potential of DEWATS technology and to identify bottle-necks which need to be addressed to improve sanitation in an urban environment that is widely deprived from proper sanitation services. The following assessment is based on the Technology-Applicability-Framework (TAF) developed by SKAT, Switzerland and was conducted in Kabul, Afghanistan in 2015.
From 14-17 October 2008, the German Federal Institute for Geosciences and Natural Resources (BGR) convened the international symposium on “Coupling Sustainable Sanitation and Groundwater Protection” in Hannover, Germany, in order to highlight the immense problems of groundwater pollution due to absent or inadequate sanitation facilities in developing countries. Together with international co-convenors (BMZ, UNEP and WHO) and supporting organizations (BORDA, DED, DWA, GTZ, IAH, KfW and […]
BORDA-DEWATS constitutes the treatment element of a sanitation concept that starts with the individual user interface, the toilet, and continues with a simplified sewer system that connects a neighbourhood of less than 10 households up to a few hundred households. The collected wastewater then enters the treatment stage. Solid matter sediments under anaerobic conditions and decomposes by producing small quantities of inert sludge and methane. […]
Kabul is the capital and largest city of Afghanistan, located in the eastern section of the country. According to a 2012 estimate, the population of the city was around 3,289,000. It was selected for the SFD program because it is a mega city with only 20% supplied with piped water and 60% informal dwellings. In Kabul it was estimated that 25% of excreta is managed […]
(31st WEDC International Conference, Kampala, Uganda, 200) Kabul water and environmental sanitation services have been affected by war, which ravaged large portions of the city in the early 1990’s. After the fall of the Taliban in 2002, a considerable influx of returnees contributed to put an ever greater stress on already deficient systems. Large-scale water supply projects were initiated. However, they tackle only areas covered by […]
