This paper presents a spatial risk analysis of waterborne diseases using analytical hierarchy process that rely on geographical information system (GIS)-automated techniques. We selected nine parameters for assessing waterborne diseases prone areas (WBDP). All the weighted parameter layers were integrated to obtain WBDP map. Of the total WBDP area, 42% area was found under medium category, 34% and 24% area under high and low category, respectively. We have also empirically analysed the factors influencing WBDP areas using regression model. Results revealed that explanatory variables like purification of water, washing hand before drinking and eating, and Surface Water Quality Index (SWQI) are the most influential and positively associated while dipping hand in the vessel is negatively associated with the WBD. Further, WBDP areas were validated by analysing their relationship with the actual incidences of WBD(s). Our study may prove to be beneficial for managing and formulating guidelines for the WBDP areas in similar geographical regions.
