“…Resource optimization is a common objective of water resource design and operation including RWH [9,27,30,54]. Minimizing life-cycle cost is often the RWH optimization objective although yield maximization for set levels of reliability has also been used [25]. Yield and reliability considerations are some of the main basis for planning and operational decisions for reservoir systems in South Africa [48].…”

“…For RWH analysis, reliability has been commonly defined as volumetric reliability (volume supplied to that demanded over the simulation period) [6,[28][29][30][31] or as the ratio of days of full supply to the total days of simulation [26]. However, volumetric reliability does not capture inter-annual variability of rainfall, and statistical analyses of the yield (or volumetric reliabilities) obtained in each year of simulation have been used to incorporate this variability [25,27]. The effect of inter-annual rainfall variability has also been assessed by analysing RWH performance for dry, normal and wet years [29] or for a typical dry year [32].…”

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.

“…This is generally undertaken by continuous simulation of the inflow and outflow [26][27][28] or using empirical relationships [4,29,30] or stochastic analysis [6,31] or a web-based tool that integrates geo-referenced rainfall patterns [32]. RWH system is also analyzed as a stormwater management component [33][34][35].…”

Rainwater harvesting (RWH) is perhaps the most ancient practice to meet water supply needs. It has received renewed attention since the 1970s as a productive water source, water savings and conservation means, and sustainable development tool. In RWH, it is important to know how much water can be harvested at a given location from a given catchment size, whether the harvested water meets the intended water quality, whether the RWH system is economically viable and whether the state regulations favor the RWH. Furthermore, the selected RWH system should be suitable to local rainfall and field conditions, downstream impacts, and socio-economic and cultural characteristics. In this regard, this paper provides an overview of the special issue on "Rainwater Harvesting: Quantity, Quality, Economics and State Regulations". The selected papers cover a wide range of issues that are relevant to RWH such as regionalization of design curves, use of spatial technology, urban agriculture, arid-region water supply, multi criteria analysis and application of artificial neural networks.

“…evaluated the influence of using different rainfall time series lengths on rainwater harvesting system sizing and concluded that a 10-year time series would be an adequate length, yielding results similar to those obtained using a 30-year time series. A decision support system was developed byFonseca et al (2017) to estimate the optimum size of the tank based on rainfall regime and water demand.…”

A review of literature related to stormwater runoff characterization and its subsequent management and treatment from 2017 was conducted. The 250 articles summarized herein are organized along three central themes: (1) stormwater quality and quantity characteristics, (2) site-scale stormwater management practices, with a focus on low impact development (LID) and green infrastructure (GI), and (3) watershed-scale performance of stormwater controls. Within each section, common research themes and future work are highlighted.
