The Law n° 14,026 from 15 July 2020, upgrades Brazil’s new national sanitation framework. Whether this upgrade in the Law is not the market sequestering the Brazilian ‘Blue and brown gold’ had been pretty debated, however, we prefer to address two research questions: what water quality should we expect in Brazil’s urban rivers? How should the management of urban rivers be planned? In this work, Porto Alegre city (South Brazil) was assessed, and the SDG 6.3.1, 6.3.2, and 6.5.1 were taken as a benchmarking tool. The main features approached suggested that: i. The new legislation may not guarantee good urban water quality; ii. The SDG 6.3.2 is essential to be determined at the municipal level; and iii. At the municipal/intra-urban level, IWRM and IUWM seem promising pathways to these desirable cities. The approach developed may provide a new perspective for urban water management.
