“…For the design of the systems for rainwater harvesting and storage, United Nations Environment Programme (UNEP) [28] recommends considering the "first flush" by subtracting the first 0.50 mm of rainfall. Khastagir and Jayasuriya [7] and Su et al [11] suggested subtracting the first 0.33 mm of the daily rainfall to improve of the quality of the water stored. For this study, the first 0.33 mm of rainfall were subtracted.…”

“…Khastagir and Jayasuriya [7] conducted a study in Melbourne, Southwestern Australia, where rainfall varies from 450 to 1050 mm per year and a drought of 12 consecutive years (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)) has been experienced. These authors designed a methodology to determine the size of tanks of rainwater storage at the household level, considering that the distribution of rainfall can vary from one point to another of the city.…”

Abstract:In cities with problems of aridity and a shortage of drinking water supply, there is an urgent need to establish alternatives for an adequate water management program. This study proposes an estimation through which users can select a rainwater harvesting system for non-drinking water consumption. For the cities of Pachuca and Mineral de la Reforma, State of Hidalgo, Central Mexico, the historical record of rainfall analyzed covers a period of 33 years . We calculated the monthly volume of rainwater harvestable from roof areas (VR, m

“…According to Khastagir and Jayasuriya [8], in Melbourne, Australia, the use of rainwater for domestic purposes has become increasingly popular since the city faced severe drought for twelve consecutive years, with annual rainfall below average. However, stormwater collected from paved roads may contain high amounts of pollutants [28].…”

There is a growing concern about the scarcity of water resources due to population growth and increased demand for potable water. Thus, the rational use of water has become necessary for the conservation of such resources. The objective of this study is to estimate the potential for potable water savings in buildings of different sectors-residential, public and commercial-in the city of Florianópolis, southern Brazil, by using stormwater harvested from porous pavements. Models were constructed to assess infiltration and rainwater quality; samples of stormwater from a local road were collected to evaluate its quality; and computer simulation was performed to assess the potential for potable water savings and rainwater tank sizing. Draining asphalt concrete slabs with two types of modifiers were used, i.e., tire rubber and SBS polymer-styrene-butadiene-styrene. The Netuno computer programme was used to simulate the potential for potable water savings considering the use of rainwater for non-potable uses such as flushing toilets and urinals, cleaning external areas, and garden watering. Average stormwater infiltration was 85.4%. It was observed that stormwater is not completely pure. From the models, the pH was 5.4 and the concentrations of ammonia, phosphorus, nitrite, and dissolved oxygen were 0.41, 0.14, 0.002, and 9.0 mg/L, respectively. The results for the stormwater runoff of a paved road were 0. 23, 0.11, 0.12, 0.08, 1.41, 2.11, 0.02, and 9.0 mg/L for the parameters aluminium, ammonia, copper, chromium, iron, phosphorus, nitrite, and dissolved oxygen, respectively; and the pH was 6.7. In the city of Florianópolis, which has a surface area of paved roads of approximately 11,044,216 m², the potential for potable water savings ranged from 1.2% to 19.4% in the residential sector, 2.1% to 75.7% in the public sector and 6.5% to 70.0% in the commercial sector.
