“…For this purpose, the parameters of conductivity, turbidity and pH of the rainwater were compared right after it was collected and after it remained 2.5 h inside the covered collector. Thus, it was concluded that the material was inert and could be used in the experiment, as also observed by Marangoni et al (2019).…”

“…In this case, the volume of rainwater discarded should be greater than 8.0 L to allow turbidity to meet the recommended. Thus, as also observed by Marangoni et al (2019), the amount of rainwater to be discarded must be locally assessed, so that its quality is in accordance with NBR 15527 (ABNT, 2007).…”

“…Subsequently, as this surface is being washed, the quality tends to be improved and to approach the quality of rainwater coming from the atmosphere. Marangoni et al (2019) also concluded that the quality of rainwater varies over a rainy event.…”

“…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). Therefore, it is important to verify that the quality of rainwater in the two cities surveyed is in accordance with 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.

In this research, an exemplary study has been conducted in order to draw attention to the importance of evaluating the existing potential on the roofs of buildings. This research offers an evaluation of the existing solar energy and rainwater potential on the total roof area of the buildings in the Izmit district, which is a central district of Kocaeli province, one of the busiest centers of industry in Turkey. The calculations in this study were carried out by using the data obtained from various institutions. As a result of these calculations, the ratio of electrical energy that can be provided with photovoltaic systems on roofs to meet the annual electricity consumption of the district was found to be 203.581%, and the annual solar energy utilization rate for a family of 4 to bring 240 liters of daily use water temperature to 60°C with an 8 m2 collector area was calculated as 66%. In addition, the ratio of rainwater that can be collected from the total roof area of the existing buildings in the district to meet the domestic water consumed by the district was found to be 33.27%.
