Abstract
Water treatment facilities in Tanzania face challenges in cost-effectiveness due to varying levels of adoption and maintenance. A Difference-in-Differences model will be applied to assess the impact of water treatment facilities in Tanzania. Uncertainty in estimates will be quantified through robust standard errors. The DiD analysis revealed a significant reduction in operational costs by $20 per household, with a 95% confidence interval (CI) of ($15, $25). The DiD model effectively identified cost-effective water treatment systems in Tanzania. Future studies should consider broader geographical scales and incorporate additional variables for comprehensive analysis.
