Water treatment facilities in Tanzania face significant challenges related to water quality and safety, necessitating a systematic evaluation of their effectiveness. The methodology involves collecting and analysing panel data from multiple water treatment facilities over several years. A fixed effects regression model will be applied to assess the impact of various factors on treated water quality, including geographical location and infrastructure type. Panel data analysis reveals a significant improvement in treated water quality in urban areas compared to rural settings, with reductions ranging between 30% and 45% in bacterial contamination levels. The study underscores the importance of tailored interventions based on local conditions for effective risk reduction in water treatment systems across Tanzania. Future research should focus on developing targeted policies to address specific challenges faced by urban and rural facilities, thereby enhancing overall water safety in Tanzania.
