“…It has been highlighted that the RHS is economically feasible. RM for tank sizing and, NPV and DPP methods for the economic assessment of RHS were used by Yoshino et al (2014). Economic analysis using NPV and DPP methods for rainwater usage in toilet flushing was carried out in Slovakia and Poland.…”

In this study, the economic feasibility of rooftop rainwater harvesting of residential and public/commercial buildings for all 81 provinces of Türkiye is assessed. The Rippl method (RM) is used for optimal storage tank estimation. The net present value (NPV) and the discounted payback period (DPP) are used for economic analysis. Two scenarios were assessed using RM for (I) residential buildings and (II) public buildings. Optimal storage tanks for scenarios I and II were estimated by the selection of minimum roof areas to supply the demand for toilet flushing water for above 95% volumetric reliability. ArcGIS 10.2 was used to illustrate nationwide results of (1) roof areas and storage tank volumes, and (2) the economic analysis. The average DPP of rainwater harvesting system is 36 years for residential buildings and 23 years for public buildings. Based on NPV analysis, 17 out of 81 provinces are economically feasible for residential buildings. The feasibility status in public buildings is 43 economically feasible and 38 infeasible. More savings in public buildings can be obtained in a relatively shorter DPP. Furthermore, regularization is more effective in public buildings than residential buildings.

“…In China, population growth and rapid acceleration of urbanization have led to an increase in demand for water. 1,2 Besides, water pollution and climate change also put urban water supply under huge pressure. Considering the importance of the issue, many studies have been carried out seeking and assessing the potential adaptation strategies and actions to cope with the water scarcity and pollution, particularly in urban areas.…”

Research focused on rainwater for human consumption is being conducted in different regions of the world. The systematic review revealed that the inadequate quality of harvested rainwater and its scarcity pose significant barriers to the installation of the catchment of rainwater for noble uses. The improper design of rainwater harvesting systems, often a result of the disregard of critical data, is a crucial factor leading to the development of poorly structured systems and inadequate management of this valuable resource. The absence of scientific knowledge about the process further compounds the problem, leading to a sense of insecurity for potential consumers. Ultrafiltration (UF) membranes, followed by ultraviolet disinfection or chlorination, have shown satisfactory results for the potability of rainwater. Additionally, the implementation of photovoltaic panel energized rainwater UF is both economically and technically feasible, and serves as an alternative to traditional water supply approaches. Most studies focused on the utilization of harvested water for non‐drinking purposes, thereby providing opportunities for new studies into effective treatment methods to cater to local and global potable water demands. Therefore, this review aimed to provide insights into the current progress, future challenges, and opportunities related to rainwater harvesting systems and their treatment for the supply of drinking water.This article is categorized under: Engineering Water > Engineering Water Engineering Water > Sustainable Engineering of Water Engineering Water > Planning Water
