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.
