Abstract

It was performed the hazard identification and prioritization of the drinking-water distribution system (DWDS) of Cali city (Colombia) supplied by Cauca River, integrating the principles of Water Safety Plans (WSP), the concepts of Delphi methodology and Geographic Information Systems (GIS). Statistical analysis of data showed drinking-water quality compliance with national regulations, classifying it as “no risk to health" (according to IRCA Index). Under normal operation of the DWDS, three maps were constructed using GIS, the first corresponding to physical and hydraulic integrity, the second to the water-quality integrity and the third to the final risk map; the data were concentrated between 5 and 18%, indicating a medium-low risk level, resulting in greater vulnerability to loss of DWDS integrity in the communes located in the center of final risk map. The integration of the consensus views of WSP team and the GIS was a useful tool in the prioritization of hazards and risk management in the DWDS, being essential to have a qualified multidisciplinary team and reliable and enough information that allow an adequate data spatial interpolation.
