Abstract Sanitary condition is one of the components that influencing public health. Bogor Regency has total area 2,663.81 km2, with total population 5,965,410 in 2019. The sanitation of Bogor Regency nearly 100% is using on-site systems. Utilization of septic tank reduces the level of contamination of surface water and groundwater. However, the sludge still containing high E. Coli that potentially caused diarrhea, vomiting disease, and others, so that the handling of the sludge needs Faecal Sludge Treatment Facilities (FSTF). Before 2016, Bogor Regency already had 10 units of faecal suction truck services, but the disposal process still was done in Kalimulya FSTF, Depok City. So, this study aims to find a feasible FSTF site location which fulfils the spatial plan, technical, and non-technical criteria. The process on the determining feasible FSTF location was employing multicriteria analysis by using Geographic Information Systems (GIS) and Analytical Hierarchy Process (AHP). Several spatial data such as the land slope, the soil type, distance from water bodies/river, the administration of Bogor Regency, as well as land use and land capability were used for FSTF site selection. Spatial analysis using GIS results in 22 locations in 15 different districts. By reconsidering the area, only 8 selected locations were surveyed and evaluated using AHP. Based on the weighting, the locations which chosen for the eastern, central, and western parts of Bogor are Cileungsi, Cibinong, and Cigudeg districts respectively.
