" --- Municipal water systems in Uganda face significant challenges related to reliability and resilience. This research evaluates the effectiveness of randomized field trials for reducing risks associated with these systems through a sample of 300 households across three municipalities. Monthly measurements of water quality parameters over one year revealed that an intervention led to a statistically significant improvement in turbidity (Q = 25\%, robust standard error ±3. 4%). This study contributes novel insights into methodological improvements for enhancing municipal water system performance,
