Abstract:	Cities in South America face many of the urban water supply challenges experienced globally including increasingly extremefuture hydroclimatic conditions and rapid population growth. These challenges are further exacerbated by historical socioeconomic inequity,informal land occupation, and poor water services management. In recent years, decision support tools that aid in structuring water supplymanagement and infrastructure pathway policies that remain robust under deeply uncertain future scenarios have been developed. However,within the context of developing countries, failing to acknowledge the complex social and institutional dynamics and stark differences inresidents’ experiences of climate extremes may lead to uneven adaptation capacities across socioeconomic strata. Toward this end, our studyextends the deeply uncertain pathways framework by applying multiobjective optimization, disaggregated service area-level assessmentsof performance and vulnerability across time, and exploratory visual analytics in the Federal District of Brazil (FDB). We highlightthe performance and robustness disparities between two water supply service areas in the FDB that differ in socioeconomic standing toreveal the impacts of deeply uncertain future hydroclimatic and socioeconomic scenarios on vulnerable populations. We further show thathistorical inequity renders poorer residents significantly more vulnerable to deeply uncertain future conditions without urgent and significantinfrastructure investments. Overall, the outcomes of our study are largely applicable to urban water utilities in regions with high levels ofhistorical regional inequity seeking to develop water management and infrastructure planning policies that are robust, adaptive, and equitable.
