Abstract
Provision of quality drinking water is paramount for sustaining good public health in urban residents. Packaged water produced and consumed across cities in Nigeria lacks integrity in protecting Health. Water safety plan based on hazard identification and risk assessment in each component of the water production system is essential in providing quality water by packaged water producing companies in Nigeria. This study aims at developing water safety plan for selected packaged water manufacturing companies in Abeokuta, Ogun State, Nigeria. Hazard identification and risk assessment were carried out based on site inspection studies, key informant interview, questionnaire survey and water sample analysis, and risk analysis using semi-quantitative risk matrix approach. The results revealed a total of 26 possible hazardous events which may compromise water quality such as on-site septic tanks and effluents discharged at source water and improper maintenance and hygiene practices within the system. Based on these, appropriate mitigation and monitoring plans were drawn for action. The research found that water safety plan is feasible for the packaged water systems, and therefore calls on the relevant stakeholders for urgent implementation towards ensuring clean drinking water and protecting public health as more and more people are opting for packaged waters due to uncertain public water safety.
Highlights
IntroductionThe conventional method of drinking water quality control based on final product monitoring is becoming outdated, as water safety plan (WSP) concept of World Health Organisation (WHO) based on hazard identification and risk management from catchment to consumers is considered as the most reliable means of safe water supply [4]

Summary
The conventional method of drinking water quality control based on final product monitoring is becoming outdated, as water safety plan (WSP) concept of World Health Organisation (WHO) based on hazard identification and risk management from catchment to consumers is considered as the most reliable means of safe water supply [4]. WSP is a documented plan that Identifies hazards; Assesses risks from catchment to consumers; Prioritizes risks, with focus on highest risks and Mitigates risks, through control measures [5]. The aim and objectives of this research work are to identify hazards and assess risk in packaged water (sachet water) production companies in Abeokuta, south-west, Nigeria, towards implementing control measures as part of water safety plan development
