“…Several countries are focusing on how to utilize rainwater because the existing water resources are limited (Nahar Myyas, Al‐Dabbasa, Tostado‐Véliz, & Jurado, 2022; Szpak et al, 2022). Rainwater harvesting and utilization is adopted by the following countries: Australia, Germany, Greece, China, Singapore, Philippines, Thailand, Japan, Jordon, Bangladesh, Indonesia, Italy, Korea, Botswana, Togo, Mali, Malawi, Ethiopia, South Africa, Namibia, Zimbabwe, Mozambique, Sierra Leone, Sweden, Spain, Tanzania, Brazil, Bermuda and the USA (Abu‐Zreig et al, 2019; Crosson et al, 2021; Domènech & Saurí, 2011; Fewkes, 2012; Ghisi et al, 2009; Karim et al, 2015; Liaw & Tsai, 2004; Matos et al, 2015; Nahar Myyas et al, 2022; Nandi & Gonela, 2022; Notaro et al, 2016; Sazakli et al, 2007; Szpak et al, 2022; Taffere et al, 2016; Villarreal & Dixon, 2005; Xiao Liu et al, 2021).…”

“…Currently, low‐impact development is widely used in homes in several countries around the world. Environmental agencies use a variety of techniques to harness storm‐water resources, including best management practices, sustainable discharge systems and water‐friendly urban design (Nandi & Gonela, 2022; Zavala et al, 2018).…”

“…) rainwater must be treated to remove impurities (see Figure 6) (Zavala et al, 2018). Rainwater quality is relatively stable with low bacterial and chemical contamination rates (Nandi & Gonela, 2022). Maximizing the use of purified rainwater resources can effectively resolve the growing water use conflict.…”

Despite the contributions of modern business practices to environmentally sustainable transformation, there is not enough information on different types of green technologies and their applications. Therefore, it is essential to identify and classify business models that focus on the management practices of green technology. While the literature on green technology business models has received increasing attention over the last decade, interdisciplinary research into this growing phenomenon is still in its infancy and fragmented. The study focuses on the need for green technology for water management worldwide. Such management practices for green technology represent a research gap in the study area because no one has worked in this field before. There should be research to address people's management practices of green entrepreneurial business. The literature highlights that the issue of water crises may be minimized with the management practices of green entrepreneurial business and by applying global green water treatment techniques. The authors believe that this study would be very beneficial for future research on policymaking based on management practices of green technology that promote environmental sustainability through a green business environment.

“…Conversely, most research about the topic employs different approaches, making it difficult to equitably analyse their results. Considering the knowledge gap regarding the financial feasibility of residential RWH systems in the literature [33] and the great diversity observed in design conventions for RWH systems [13], this study aims to provide relevant information for potential investors or policymakers through presenting a comparable financial feasibility analysis among cities with different rainfall characteristics. Moreover, the study classifies the initial outlays of RWH systems of varied sizes into relevant categories for RWH design, thus providing a reference for further studies or other locations.…”

Extensive implementation of rainwater harvesting (RWH) systems can promote substantial improvement in urban water resource management. Therefore, establishing the financial feasibility of RWH systems is imperative for their dissemination. This study evaluated the influence of rainfall time series indicators (average annual rainfall, seasonality index and behaviour of periods without precipitation) and design variables (catchment area, rainwater demand, number of inhabitants, potable water demand and rainwater tank size) on the financial feasibility of RWH systems in eight Brazilian cities. Correlations between rainfall indicators and financial feasibility were introduced, along with sensitivity analysis of design variables. Financial feasibility was obtained in 30% to 70% of the simulated scenarios. Initial investment and operating costs varied significantly among the eight cities according to local prices. Systems with a catchment area of 200 m2 were capable of supplying, on average, 90.5% of the maximum rainwater consumption observed in this study. Local variation of potable water tariff schemes affected the financial feasibility of RWH systems. The number of inhabitants was the most influential design variable on the financial feasibility of RWH systems, followed by the rainwater tank size. Places with lower rainfall seasonality indexes and lower incidence and duration of dry periods are likely to lead to greater financial feasibility.

“…El aumento demográfico y urbanístico, los impactos ambientales del crecimiento económico y el usufructo de los recursos naturales hacen necesario encontrar sistemas alternativos para la gestión y la planificación del agua urbana (Serrao-neumann et al, 2019). Por este motivo, se ha incursionado en el aprovechamiento del agua en diversas formas y estados, como la desalinización, la recolección y aprovechamiento de agua lluvia y la inclusión de una política pública para la gestión del recurso hídrico (Nandi & Gonela, 2022).…”

Sistemas alternativos de captación y almacenamiento de agua desde la perspectiva del metabolismo social, Quibdó, Colombia

El metabolismo social estudia las relaciones de intercambio entre la sociedad y la naturaleza. Este permite analizar la sostenibilidad de los recursos naturales, como el agua, ligada a las relaciones entre la sociedad y la naturaleza. En este sentido, los grupos poblacionales tienen un peso significativo en el incremento del consumo de recursos y la trasformación de la energía. Por eso, los sistemas alternativos de captación y almacenamiento de agua son importantes, pues permiten su autogestión. Esta investigación buscó caracterizar los sistemas de captación y almacenamiento de aguas lluvias presentes en la ciudad de Quibdó, en las áreas no conectadas al sistema de acueducto, en relación con el metabolismo social. Para ello, se utilizó una metodología de enfoque mixto, con técnicas cualitativas y recolección de información cuantitativa. Se realizaron visitas a 150 viviendas en las cuales se evidenciaron los sistemas de almacenamiento y las estructuras para el almacenamiento del agua; de estas, el 41,8 % fueron tanques elevados y el 40,2 % tanques bajos. Se encontró en un hogar un consumo promedio de agua de lluvia de 500 L/día, utilizados en usos potables (preparación de alimentos, hidratación y atención a bebes y niños) y usos no potables enfocados principalmente en aseo (personal, vivienda, lavado de ropa). Dependiendo de la capacidad de almacenamiento de agua de la vivienda, esta puede durar entre uno y cinco días sin precipitación de lluvias; sin embargo, en temporadas de lluvias hay una recarga constante de los sistemas de almacenamiento que evita la carencia del agua.
