Financial analysis of non-sewered sanitation using eSOSView software (Indonesia)

In Bali Province, although access to basic sanitation services is 95%, only 15% of the population have access to safely managed sanitation, and 4% still practice open defecation. This percentage includes septic tanks that are emptied at least once in the last five years. Open defecation and the high rate of unsafely-managed sanitation in Bali can potentially result in wastewater infiltration into drinking water sources, discharging enteric microorganisms and fecal- borne pathogens, such as E. coli. As centralized, city-scale domestic waste treatments are expensive and complex, on-site sanitation is the key strategy to achieve safely-managed sanitation that includes fecal sludge management in many low- and middle- income countries (LMICs) such as Indonesia. WASH services are considered sustainable if the five dimensions of sustainability factors (financial, institutional, environmental, technological, and social) are adequately addressed in the WASH program. This research focuses on financial flow modeling to achieve universal access to safely- managed sanitation using a financial simulator, eSOSView^TM, in Tabanan Regency, Bali. The primary data collection method used in this research is the Real Demand Survey (RDS) for the households. The selection of the financial model uses Multi Criteria Analysis (MCA) which results in the conclusion that model 3 is the chosen business model to achieve the target of 100% safely managed sanitation in Tabanan Regency, Bali.
