Development of GIS based contamination risk assessment in water distribution systems
conference contribution
posted on 2018-02-12, 15:09 authored by S. Mohan, K. Danimon, Kalanithy VairavamoorthyThe study aims at developing a GIS based contamination Risk Assessment procedure in water distribution systems. Water
distribution network analysis model EPANET 2.0 was integrated with ArcGIS 8.3 for the water quality analysis retrieving
data from the GIS database. Water supply system of Zone VIII of Guntur, India was selected for the case study. The results
of water quality simulation were displayed in the GIS interface and the areas affected were mapped with the spatial analyst
tool of GIS. Data on number of household connections and standpipes affected by a particular event of contamination was
also retrieved from the GIS database. The events resulting in high risk were identified from the GIS maps. This information
helps in the decision making process of prioritizing the maintenance activities particularly, in case of limited fund
availability. Since the resource availability for maintenance activities are limited in developing countries, prioritizing the
activities using GIS helps to achieve maximum risk reduction.
