From the accelerated process of global urbanization, themes that permeate the socio-environmental context of cities, echo as strong practical aspects to be debated and studied, for example, aspects of urban policies connected with governance. In this sense, this research seeks to answer the following question: to what extent do urban policies, together with the triad environmental, social, and governance (ESG), articulate and promote a sustainable production of urban spaces? The objective was to explore the existing gaps in the interrelationship of urban policies and governance through the perspective of sustainable production of urban spaces, seeking evidence in theoretical and practical ways. The methodology uses bibliometric techniques to systematically review the integration of documents specified in methodological treatment, first by establishing key search words, and sequentially defining the databases that could provide the necessary data for the systematic reflections of the research, narrowed to a period between the years 2017 and 2021 and through Scopus and Web of Science databases. Our research provides evidence that urban policies, connected with the execution of governance, become important both for the promotion of ecological balance and for the environmental maintenance of cities, striving for their preservation and at times restoration and revitalization, thus enabling the proposal to establish urban policies in connection with ESG.

The capture and reuse of rainwater is a viable alternative in regions where water is scarce or in places where water consumption is high. However, the economic viability of the implementation of an appropriate system is reduced by the need to install pumps, filter pipes and filters. This case study was focused on evaluating the potential for the harvesting and reuse of rainwater in a prison in Santa Catarina State, Brazil. The experiment was carried out at Tubarão prison, where three sampling points were strategically selected for the collection of rainwater. The total area of the prison is 4793.73 m² and in this research only the roof areas of the buildings used to keep inmates in closed and semi-open regimes were used. In total, 3483.53 m² were considered, which guarantees an annual capture of 4314 m3 of water and corresponds to 17% of the water consumed in the prison, providing potential savings of US$ 5408 per year. After collection, the water was filtered through an activated carbon filter to be applied as reuse water. The results demonstrate significant reductions for all parameters analyzed. In general, the average efficiency was above 70%. The best results were obtained for the removal of suspended solids (94%), dissolved solids (94%), total solids (83) and phosphorus (81%). In addition, removal values for color, chlorides and nitrate were around 70%, verifying that the filtration system with activated carbon is efficient for harvested rainwater.
