RISK ASSESSMENT IN WATER DISTRIBUTION SYSTEMS FRAMED IN A WATER SAFETY PLAN
Risk assessment is a key stage in a water safety plan (WSP) and it is achieved by identifying hazards or hazardous events and estimating risks. This study evaluated health risks in the drinking water distribution system (DWDS) of the city of Cali (Colombia), which is supplied by the Cauca River. Hazardous events were identified, and, subsequently, a risk estimation was completed using a previously adapted semi-quantitative risk matrix. The risk estimation was initially made without considering the existing control measures in the DWDS. It was then redone considering the level of effectiveness of these measures. The results showed the events with the highest level of risk associated with the loss of physical and hydraulic integrity of the DW... Ver más
