“…Apart from these, other studies assessing the quality of harvested rainwater are available for different parts of the world: Lye (1987) in Kentucky-USA, Fujioka et al (1991) in Hawaii, Coombes et al (2000) in NSW-Australia, Handia (2005) in Zambia, Hernandes and Vieira (2005) in Southeast Brazil, Peters et al (2008) in Bermuda, Ahmed et al (2009) in SEQAustralia, Daoud et al (2011) in Palestine, Gikas and Tsihrintzis (2012) in Northeast Greece, Shuster et al (2013) in Ohio-USA, Van der Sterren et al (2013) in Sydney, and Dobrowsky et al (2014aDobrowsky et al ( , 2014b in WC-South Africa. Finally, a summary of the reports on the chemical and biological quality of harvested rainwater tanks can be found in Kwaadsteniet et al (2013).…”

“…RWH could also lead to a feeling of independence from centralized water supply [9]. Although rainwater sometimes fails to meet drinking water standards [14][15][16][17][18], the quality of rainwater is usually superior to that from surface water and groundwater that may have been contaminated [19]. Sazakli et al [20] report that rainwater from rooftops generally meets international drinking water quality standards.…”

Abstract:The objective of this study was to develop guidelines for analysing rainwater harvesting (RWH) systems of shopping centres in South Africa. A model consisting of three dimensionless relationships relating rainwater supply and demand to storage capacity, yield and reliability was formulated. Data from daily simulation of potential RWH systems of 19 shopping were used to obtain the relationships. The simulations revealed within-year storage behaviour with considerable variation of annual yield. By applying the Weibull plotting position formula, yield-reliability relationships were derived. The aim to maximize yield and reliability whilst minimizing storage identified Pareto-optimal combinations of the three variables and these combinations were used to develop two dimensionless relationships. An additional relationship based on the dependence of the slope of the yield-reliability plots on yield was formulated to enable analysis of hydrologically non-optimal systems. Verification tests using four RWH systems obtained results that matched those from simulation and the model could therefore be applied for RWH feasibility analysis and preliminary design. This study highlights the need to incorporate inter-annual variability in RWH analysis and shows how reliability can be used to quantify this. This study further demonstrates how reliability can be fully integrated into regression relationships for generalized RWH analysis.

“…Runoff from rooftops is often considered unpolluted [10] or at least is of relatively good quality compared with runoff from surface catchments [11]. However, there is still disagreement about the quality of rooftop runoff, ranging from good or acceptable [12,13] to contaminated [14,15], depending on the roofing material, environmental conditions and atmospheric pollution. Subject to basic treatments such as filtration and/or chlorination, as necessary, collected rainwater can be utilized for different non-potable uses, including toilet flushing, washing machine use and garden irrigation (or any other use that does not require high-quality water).…”

Abstract:Rainwater harvesting (RWH) may be an effective alternative water supply solution in regions affected by water scarcity. It has recently become a particularly important option in arid and semi-arid areas (like Mediterranean basins), mostly because of its many benefits and affordable costs. This study provides an analysis of the reliability of using a rainwater harvesting system to supply water for toilet flushing and garden irrigation purposes, with reference to a single-family home in a residential area of Sicily (Southern Italy). A flushing water demand pattern was evaluated using water consumption data collected from a sample of residential customers during an extended measurement campaign. A daily water balance simulation of the rainwater storage tank was performed, and the yield-after-spillage algorithm was used to define the tank release rule. The model's performance was evaluated using rainfall data from more than 100 different sites located throughout the Sicilian territory. This regional analysis provided annual reliability curves for the system as a function of mean annual precipitation, which have practical applications in this area of study. The uncertainty related to the regional model predictions was also assessed. A cost-benefit analysis highlighted that the implementation of a rainwater harvesting system in Sicily can provide environmental and economic advantages over traditional water supply methods. In particular, the regional analysis identified areas where the application of this system would be most effective.
