Sanitation in Maranhão: projections for meeting basic sanitation targets by 2033

Abstract

Sanitation, a service essentially connected to the environment and public health, encompasses activities such as the supply of drinking water, sewage management, solid waste collection, and stormwater management. Despite notable efforts and progress in this sector in Maranhão, data indicate that the state still has some of the lowest sanitation indicators. This article aims to analyze whether, by 2033, the state of Maranhão and its capital, São Luís, will achieve the targets set by the Sanitation Legal Framework (Law No. 14,026/2020) and the Sustainable Development Goal (SDG). A quantitative methodological approach was adopted, complemented by a bibliographic review. The research reveals that, by 2033, only São Luís will reach the target of 99% drinking water supply. However, neither Maranhão nor its capital will achieve the target of 90% sewage collection coverage within the same period.
