Basic Sanitation in Morro Da Mangueira, Rio De Janeiro: Socio-Environmental Inequalities, Urban Infrastructure, And Challenges for Sustainable Water Resources Management

ABSTRACT Background: This article examines inequalities in access to basic sanitation in Morro da Mangueira, Rio de Janeiro, starting from a concrete question: how do announced infrastructure improvements translate into services that are actually available to residents?Objective: To analyze inequalities in access to basic sanitation in Morro da Mangueira and the relationship between documented interventions and the effective provision of services.Methods: The study adopts a qualitative, documentary approach based on legislation, official statistics, planning documents, inspection records, scientific literature, and publications by the concessionaire.Results: The sources confirm the installation of water supply network sections in Candelária and document the construction of a reservoir in Complexo da Mangueira. However, they do not make it possible to determine the continuity of supply in all sectors or to quantify, at the scale of the hill, sewerage coverage, the regularity of waste collection, or drainage efficiency. The discussion shows that network extension and investment announcements are not, in themselves, sufficient measures of universal access. A set of actions is proposed focusing on territorial assessment, operational integration of services, and public monitoring of indicators.Conclusion: Reducing inequalities depends both on infrastructure works and, on the ability, to verify the quality and continuity of service provision in each locality.Keywords: basic sanitation; Mangueira; environmental justice; water supply; favelas; water resources management.
