“…The operation of RWHS for certain buildings in the areas of cold semi-arid climates can supply about 70% of non-potable water (Molaei et al, 2019). The development of RWHS used as an effective alternative water supply can deal with the water scarcity by optimizing the performance of RWHS operation (Dismas et al, 2018;Notaro et al, 2017;Pacheco and Campos, 2016).…”

The problem of water shortages faced by many countries including the country that having sufficient water source needs to be provided a practical engineering solution. The reliability analysis of rainwater harvesting system (RWHS) installed at the commercial building of AEON Taman Universiti located in Johor Barhu city of Malaysia was based on the rainfall pattern, rainwater use and rainwater storage tank. The economic analysis using the net present value (NPV), return on investment (ROI) and benefit-cost ratio (BCR) was performed to assess the optimal management of RWHS installed during the period of construction and retrofitted after the operation of commercial building. The results showed that the balance of water supply and demand is reliable to implement the RWHS and the optimal management of 1000-m 3 RWHS tank installed during the construction could be more promising than that retrofitted after the operation of AEON Taman Universiti commercial building. The operation of RWHS installed during the construction of building is obviously more feasible due to the values of NPV, ROI and BCR tend to be high. The reliability and economic analysis of RWHS installed during construction and that retrofitted after operation of commercial building demonstrated the benefit of RWHS installation will contribute to the future of building design for achieving an effective water management.

“…Several studies have been conducted in the recent past that examined the hydrological feasibility and economic viability of RWHS from South Asia and around the world, and they have analyzed the determinants of adoption and the factors that influence the viability of these systems (Kumar, 2004(Kumar, , 2018Kumar et al, 2006Kumar et al, , 2008Pacheco & Campos, 2017;Ranaee et al, 2021). Here, we mean RWHS in general, like the construction of RWHS in the natural catchments, rooftop catchments, etc., for irrigation and other purposes.…”

Identifying determinants of sustainable water management at the household level through rainwater harvesting systems in Nepal

The urban water supply systems around the world are highly stressed at present due to growing water demand caused by rapid population growth and unplanned urbanization. The growing environmental awareness and water supply restrictions have made, rainwater harvesting systems (RWHS) a priority as well as a necessity in many countries. To improve urban water security, the practice of an RWHS is increasingly being adopted in the cities and towns of developing countries. This study aims at identifying the factors affecting the adoption of rainwater harvesting for household uses in the Kathmandu valley (KV) of Nepal. The results were drawn from a survey of 405 respondents who reside in the KV. To explain the determinants of adaptation, structural equation modeling (SEM) was used. Results show that independence for water access and system sophistication are significant for the adaptation of RWHS and relative advantage plays a moderating role that has partial mediation among dependent and independent variables with a significant relationship. Thus, variables like independence for water access, system sophistication, relative advantage and sustainable use should be highlighted for a sustainable supply of water. For this, we recommend effective policy interventions at the local and national level for the adoption of RWHS and its advantages in terms of safeguarding water in the long run at the present changing climate scenario.

“…In the case of water, rainwater harvesting (RWH) is a potential circular solution that fosters regenerative and closed-loop systems that could alleviate the pressure on both water and stormwater infrastructure. Solving these threats to our conventional infrastructure has led to an exponential increase in RWH studies (Campisano et al, 2017;Leong et al, 2017;Pacheco and Campos, 2017;Vieira et al, 2014).…”

Water management plays a major role in any city, but applying alternative strategies might be more or less feasible depending on the urban form and water demand. This paper aims to compare the environmental performance of implementing rainwater harvesting (RWH) systems in American and European cities. To do so, two neighborhoods with a water-stressed Mediterranean climate were selected in contrasting cities, i.e., Calafell (Catalonia, Spain) and Ukiah (California, US). Calafell is a high-density, tourist city, whereas Ukiah is a typical sprawled area. We studied the life cycle impacts of RWH in urban contexts by using runoff modeling before (i.e. business as usual) and after the implementation of this system. In general, cisterns were able to supply >75% of the rainwater demand for laundry and toilet flushing. The exception were multi-story buildings with roofs smaller than 200m, where the catchment area was insufficient to meet demand. The implementation of RWH was environmentally beneficial with respect to the business-as-usual scenario, especially because of reduced runoff treatment needs. Along with soil features, roof area and water demand were major parameters that affected this reduction. RWH systems are more attractive in Calafell, which had 60% lower impacts than in Ukiah. Therefore, high-density areas can potentially benefit more from RWH than sprawled cities.
