“…The proposed conceptual plan for comprehensive RWH adoption by the authors could become appears that a number of factors could influence in encouraging the respondents from the accepting-side to adopt RWH. The ranking of the influencing factors described by non-RWH-users is found to be not in line with the most literatures or experiences from foreign countries such as the UK, India, Korea and others (Jung, Lee, Choi, & Hong, 2015).…”

Malaysia is not entirely spared from regular water shortages although it is located in a water rich region. The authors' previous study clarified that rainwater harvesting (RWH) might be one of the possible priority measure for promotion of water conservation. In line with such recognition, it is necessary to understand the relevant stakeholder's perceptions and attitudes towards the RWH practice. Thus, a set of structured interviews and questionnaire surveys were conducted among the stakeholders. Selangor, the most developed state in Malaysia was chosen as a case study. Herein, the stakeholders consist of (i) the fostering-side, namely the policy-makers, equipment-makers and NGOs/community leaders, and (ii) the accepting-side, namely the users and expected users of RWH. It is verified that the fostering-sides are generally in the medium level of participation. They are willing to support RWH on condition that accepting-sides become more positive to cooperate for RWH adoption. The accepting-sides are commonly in the low level of awareness. They seem to show more positive response when presented with proposal of low-cost RWH. To overcome the deadlock relationship between the two parties, several approaches that can be beneficial to both parties are proposed such as income tax and import duty exemption for rainwater harvesting system installations and reward-based RWH applications.

“…Captured rainwater can be applied on-site or on a larger scale for community purposes, and communal rainwater tanks may be economically feasible [32]. Rainwater harvesting may be feasible for individual users, subject to the specific water demand and roof area [31,33], but its economic feasibility may be limited for some households because it does not provide a continuous supply of water and needs to be supplemented with other sources [34]. As an alternative source, however, rainwater can provide significant volumes of water, and it is estimated that up to 80% of rainfall could be harvested from urban rooftops in the U.S. [35].…”

Water availability is increasingly stressed in cities across the world due to population growth, which increases demands, and climate change, which can decrease supply. Novel water markets and water supply paradigms are emerging to address water shortages in the urban environment. This research develops a new peer-to-peer non-potable water market that allows households to capture, use, sell, and buy rainwater within a network of water users. A peer-to-peer non-potable water market, as envisioned in this research, would be enabled by existing and emerging technologies. A dual reticulation system, which circulates non-potable water, serves as the backbone for the water trading network by receiving water from residential rainwater tanks and distributing water to households for irrigation purposes. Prosumer households produce rainwater by using cisterns to collect and store rainwater and household pumps to inject rainwater into the network at sufficiently high pressures. The smart water grid would be enabled through an array of information and communication technologies that provide capabilities for automated and real-time metering of water flow, control of infrastructure, and trading between households. The goal of this manuscript is to explore and test the hydraulic feasibility of a micro-trading system through an agent-based modeling approach. Prosumer households are represented as agents that store rainwater and pump rainwater into the network; consumer households are represented as agents that withdraw water from the network for irrigation demands. An all-pipe hydraulic model is constructed and loosely coupled with the agent-based model to simulate network hydraulics. A set of scenarios are analyzed to explore how micro-trading performs based on the level of irrigation demands that could realistically be met through decentralized trading; pressure and energy requirements at prosumer households; pressure and water quality in the pipe network.

“…Berwanger and Ghisi (2014) conducted feasibility analysis for a city in Brazil and commented that rainwater tank will be feasible for only selective cases depending on water demand and RA. Jung et al (2014) conducted economic feasibility of rainwater tanks for seven major cities of South Korea considering continuous supply of rainwater demand and concluded that to be able to achieve continuous supply the required rainwater tank size is not economically feasible. Due to this fact often a smaller tank is used which requires augmented supply from main water supply or other sources.…”

Among all the alternative options to minimise potable water demand, rainwater harvesting system has received the highest level of attention due to its easy collection and reuse potentials. However, available methods of quantifying potential water savings from rainwater tanks are questionable. This paper presents development of generalised equations for the quantification of potential water savings under different climatic conditions for an Australian city, Adelaide. An earlier developed daily water balance model, eTank, which can calculate potential water savings in three climatic conditions (dry, average and wet) was used for this purpose. Several relationship graphs of water savings were produced through model calculations for different input parameters.Reference to this paper should be made as follows: Paudel, U., Imteaz, M.A. and Matos, C. (2018) 'Equations for potential water savings through rainwater harvesting for different climatic conditions in Adelaide (Australia)', Int. . He completed his Bachelor of Science in Civil Engineering from Bangladesh University of Engineering Technology, Dhaka, Bangladesh in 2001. After the graduation, he worked actively in the research, design and implementation of sustainable water and wastewater treatment technologies in Nepal. He also completed his Master's in Engineering Studies specialising in water engineering from University of Technology, Sydney in 2008.
