Resumen:
Water and sanitation management faces major challenges due to the rapid urbangrowth of metropolitan areas and the resulting pressure on water resources.Metropolitan areas often combine formal and informal water and sanitation servicesand regularly face shortages, leakages, and other situations involving risk to users andthe environment. This work presents an integrated approach for the development andimplementation of a Water and Sanitation Safety Plan (WSSP) for metropolitan areas,especially in developing countries. The plan allows for the assessment of all the risks associated with the components of the urban water cycle by means of a semiquantitativeapproach. In the case study described, overall risk estimated was 37.2% (44.0% and 30.3% for the drinking water supply and sanitation sub-systems, respectively). Highest risk values were obtained for components Water treatment (53.0%) and Wastewater treatment (51.7%). Our assessment took into account the formal and informal sanitation components of the water and wastewater management cycle and included a multi-institutional analysis of the entire system. Results obtained may contribute to establishing new policies and guidelines for the protection of public health and the local environment in our case study and other areas of the region with similar contexts and comparable institutional settings.
