This observation corroborates with the one concluded by Andrade et al (2017). However, it stands out that the worsening of the rainwater quality when having contact with the impurities of the roof tends not to change its classification based on the recommended by NBR 15527 (ABNT, 2007).…”

Rainwater harvesting (RWH) is an alternative to the problem of water scarcity. However, its quality must be analyzed before its use, so that it does not represent any danger to the consumer. Thus, the objective of this paper was to analyze the spatial-temporal variation of water quality of rainwater in two cities and observe whether its parameters meet the norm related to the subject. In addition, the concentration of total suspended solids (TSS) that flow into the drainage system was also simulated. Rainwater samples were collected at several points in Congonhas and Ouro Branco - MG, over a period of two years. The results showed that there was spatial-temporal variation in water quality. There were points where the quality met the standard in some moments and did not meet in others, due to its temporal variation. It was also observed that the catchment surface influenced the quality of rainwater, so that the water that came into contact with the roof had its quality deteriorated, at first. However, throughout the rainy event, the quality improved, but at certain times, it was not enough to meet the standard. The rainwater quality simulation, carried out at SWMM, showed high concentrations of TSS, which were higher to that allowed for launching into receiving bodies.

“…63 articles were selected from the research carried out in the periodicals, 27 of which were international and 36 national -these were obtained from publications in periodicals and special scientific events. About 25 articles of the analyzed publications (or 40%), investigated the quality of the rainwater in the samples obtained from the storage tank and/or specific points of the rainwater system in various States in Brazil, such as Santa Catarina (ANDRADE et al, 2017), Rio de Janeiro (MOREIRA et al, 2019), Minas Gerais (MIMURA et al, 2016 and Paraná (TEIXEIRA et al, 2017). Most of the publications that appeared in foreign countries assessed the characteristics of rainwater in terms of the influence of geographical locality, climate and urbanization/industrialization on water quality.…”

“…In general, after the initial treatment of an amount of collected rainfall (through filtration technology and the disposal of the initial flow of contaminated water known asfirst flush), the volume that is stored is made available for the harvesting of water for lowerpurposes such as irrigating gardens, flushing toilets and washing floors or vehicles.In these situations, specific treatments are recommended such as disinfectants, particularly because it is essential to prevent pathogens and microorganisms from being deposited and washed off the rooftops into the water tanks. (ANDRADE et al, 2017;TEIXEIRA et al, 2017, GUIMARÃES et al, 2019ROCHA et al, 2011).…”

The main aim of this study was to assess the determining factors, such as storage capacity, water quality and public policies, involved in the publication of scientific articles. It also sought to investigate the influence of Brazilian legislation on particular systems for harnessing rainfall in Brazil. The methodology entailed conductinga bibliographical research of the municipal, State and federal legislation in force in Brazil for the governance of technical standards and the scientific articles about the harvesting of rainwater. A total of 6 technical standards were analyzed, together with 56 legal referrals and 63 articles from national and international periodicals taken from the Google Cloud Platform for Education, SciELO, Science Direct and CAPES, and based on the principal keywords such as a “system for harnessing rainfall” and “rainwater harvesting systems”. The results show that the works that predominated were studies on the qualitative and quantitative features of rainfall and that around 80% of the publications analyzed, addressed/made use of the main legislative instruments with regard to storage, water quality and the construction and operation of systems.All the Brazilian States with the exception of three (Minas Gerais, Roraima and Pará), have at least one incentive policy for the creation or installation of catchment systems, storage and the harvesting of rainwater in the country. It can be concluded that the laws sanctioned in Brazil for rainwater are of recent origin and that they provide mechanisms for offering incentives and ensuring their enforcement in accordance with technical criteria. However, they need updating so that there can be a broader understanding of the question of how policies for the management of water operate in the country.

“…In Brazil, several studies have considered the technical evaluation of rainwater harvesting for specific buildings, normally placed in urban centres (Sampaio & Alves 2017;Geraldi & Ghisi 2018), including households (Ghisi & Oliveira 2007;Ghisi et al 2012;Marinoski et al 2018), industrial companies (Azambuja Teixeira et al 2016;Andrade et al 2017) and educational institutions (Salla et al 2013;Marques et al 2014;Amorim et al 2017;Silva et al 2019;Thomé et al 2019).…”

Socioeconomic potential for rainwater harvesting systems in southern Brazilian municipalities

The implementation of rainwater harvesting (RWH) systems depends on technical and socioeconomic assessments. However, most studies do not consider socioeconomic aspects, which could lead to different degrees of RWH implementation and technology selection due to economic constraints and local regulations. We evaluated the socioeconomic potential for RWH as an alternative for water supply of 24 Southern Brazilian municipalities with less than 50,000 inhabitants. A total of 10,080 RWH configurations were assessed and a reliability analysis was carried out to define the RWH system configurations potentially implementable (RWH+) in each municipality. RWH economic benefits were estimated from a social point of view, based on the reduction of the monthly water payment. Overall, RWH+ supplying higher demands with higher economics savings were feasible, as expected. However, several municipalities that showed RWH+ supplying 100% of the domestic water demands obtained lower economic savings, due to low water tariff and water consumption. Still, a set of municipalities presented RWH+ for rainwater demand replacing 50% to 60% of the residential demand, for which the high-water tariffs reflected in higher economics savings. The advantages of using the RWH systems outstand even more when the investments at Federal and Local levels are considered.
