Despite the growth in the supply of these sewage services, which practically doubled in the last thirty years in the Northeast region of Brazil, from 26.1% in 1989 to 52.7% and from 12.9% to 43% of municipalities in the Midwest region, the provision of basic sanitation services in Brazil is still far from an acceptable level.
According to the Trata Brasil Institute, a survey based on data released by the National Sanitation Information System (SNIS - base 2018), shows that advances in this area are insufficient for Brazil to fulfill national and international commitments in treated water, collection, and treatment of water sewers.
