Water scarcity in Mexico City leads to intermittent water supply, causing households to adapt by storing, reusing, and conserving water. While most residents are satisfied with the quantity of water they receive, they incur financial and non-financial costs to make it work. These costs include buying storage containers, pumps, and using alternative water sources, as well as spending time managing water and experiencing a decline in water quality. Marginalized households bear the brunt of these impacts due to unequal distribution of public water supply. The study suggests policy solutions to address water quality deterioration during storage and the inequalities of intermittent water supply.
