Abstract The main aim of this work is to present operational problems concerning the safety of the water supply and the procedures for risk management systems functioning public water supply (CWSS) and including methods of hazard identification and risk assessment. Developed a problem analysis and risk assessment, including procedures called. WSP, which is recommended by the World Health Organization (WHO) as a tool for comprehensive security management of water supply from source to consumer. Water safety plan is a key element of the strategy for prevention of adverse events in CWSS.

El usuario final es el último componente de los Sistemas de Abastecimiento de Agua Potable (SAAP) y se caracteriza porsu vulnerabilidad frente a los peligros debido a su cercanía al punto de consumo. En este estudio se realizó la evaluacióndel riesgo en el usuario final del SAAP de la ciudad de Cali abastecido por el río Cauca, enmarcado en la filosofía de losPlanes de Seguridad del Agua (PSA), usando herramientas como la matriz de peligros/eventos peligrosos, el monitoreo decalidad de agua, la aplicación de encuestas a los usuarios y la construcción de matrices semicuantitativas para estimaciónde riesgos. Los resultados evidenciaron poca percepción del riesgo y desconocimiento de la responsabilidad del usuariofinal en la protección de la calidad del agua, lo que puede generar conductas inadecuadas comprometiendo la integridaddel sistema interno de distribución. Aunque la mayoría de variables analizadas cumplieron la reglamentación nacional,algunos puntos registraron bajos valores de cloro residual y elevado recuento de bacterias heterotróficas, lo que sugierepotenciales riesgos por presencia de biopelícula. La participación y compromiso de todos los actores involucradosson estrategias fundamentales para evitar conductas inadecuadas y reducir riesgos, además del fomento de campañaseducativas como lo indica la reglamentación nacional.

Background: Better water quality, improved sanitation and sound water resource management will improve public health and economic development in low-income countries. Water safety plan-based risk assessment and risk management from catchment to consumers are the modern and efficient approaches to safe drinking water supply established by World Health Organization. Thus, this paper aimed to assess risk from catchment level to consumers in the community of Brikama. Methods: This study report assessments of risk or hazards from catchment to consumers in Brikama Water Treatment Plant (BWTP), West Coast Region, The Gambia. The various means of data collection used include water quality monitoring, visual field inspection and questionnaire survey to explore data on where the water supply system goes wrong from catchment to consumers, so as to provide an improvement plan. Results: Overall, the day-to-day administration of services at BWTP was very impressive. The fencing of all the 17 boreholes at catchment sites has drastically reduced the risk of contamination including treatment systems and distribution lines. There are less risks observed and constant monitoring of the system was ensured. However, at the consumer end, there are some risks with poor practices associated with water handling, storage and hygiene measures at the household level. Some still use some unclean 20-liter containers to store water and indiscriminately kept drinking cups on the floor and unclean surfaces, and 50% lacked WASH knowledge related to water treatment, such as boiling and filtration at households. The overall perception of water storage, sanitation and hygiene practices could be rated moderately good. Conclusion: The overall findings of this study have shown tremendous achievement in the government's commitment to providing potable water to the people in Brikama Local Government Area. WASH education in the study area is recommended to avoid waterborne disease infections.
