Abstract: Blackwater reuse is a growing practice, integrating technological solutions for water sustainability and natural resource management. This master’s research proposes to evaluate the Water Reuse Production Station (EPAR) installed in an administrative building in Porto Alegre, RS, Brazil, a development that holds LEED Platinum certification for sustainable buildings. The aim is to analyze its potential as a model of environmental and economic efficiency in sustainable urban constructions. Based on the future collection and analysis of operational monitoring data and water quality parameters, the expected results will indicate the feasibility of EPAR in reducing potable water consumption, verifying its compliance with the regulatory criteria of CONSEMA-RS Resolution No. 419/2020. The economic analysis intends to demonstrate potential reductions in operational costs and the mitigation of environmental impacts, reinforcing the replicable potential of this technology in different urban contexts. This master’s work will aim to contribute to advancing knowledge on the eco-efficiency of blackwater reuse and to support future public policies for incentive.
Key words: eco-efficiency, EPAR, water reuse
