Outline of Final Research Achievements

The purpose of the study is to propose a methodology of developing alternative scenarios for environmental sanitation improvement in Asian cities. The study profiled sanitation management of seven cities, characterized water consumption and wastewater discharge in five cities, developed water and mass flow models in three cities, and established a water balance model in a city. An alternative scenario was proposed in Hanoi, Vietnam, composed of septic tank performance improvement and intercept-type sewer use, and its impact was estimated by using the above established model and investigation results. In addition, an alternative scenario was also proposed for a slum in Khulna, Bangladesh. A participatory workshop employing diarrhea risk data was developed and applied into two slums so that slum residents were able to select the scenario by themselves which were feasible and able to effectively reduce the risk. Thus, the methodology developed and used has been verified.
