Household Water Insecurity in Mexico: Household Storage Strategies and Well‐Being

ABSTRACT This study employs a subjective well‐being approach to assess the negative impact of water intermittency on well‐being, as well as the benefits of implementing water storage strategies. Utilizing official, representative data from Mexico, the research empirically explores the well‐being consequences of household water insecurity and the mitigating role of coping mechanisms. Regression analysis reveals that rooftop tanks significantly improve life satisfaction compared to households without storage, especially when water is supplied at least every third day. The effectiveness of rooftop tanks is reduced in conditions of more severe household water insecurity. These findings underscore the need for policies that enhance water access and promote efficient storage solutions to mitigate the adverse effects of water scarcity. The implementation of rooftop tanks presents a practical solution to sustain well‐being, particularly in areas where structural challenges hinder continuous water supply.
