“…The technical standard includes analysis of the potential use and performance of the system. This assessment generally considers the following variables: tank storage volume and water use demand, given a catchment (roof) area and rainfall time-series (Hashim et al 2013;Sanches Fernandes et al 2015;Lopes et al 2017;Brandão & Marcon 2018;Guo & Guo 2018;Amos et al 2020;Pala et al 2021).…”

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.

“…In Brazil, the collection, use of rainwater and sizing methods for the rainwater accumulation reservoir are regulated by means of the norm NBR 15527 (ABNT, 2007) (Brandão & Marcon, 2018a;Brandão & Marcon, 2018b). This norm also presents the quality parameters that rainwater must meet to be used (Marangoni et al, 2019).…”

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.
