Investigation of Microbiological Quality Changes of Roof-Harvested Rainwater Stored in the Tanks

Rainwater has been found to be a valuable source of drinking water in Europe, especially in such crisis situations as those caused by contamination of water uptake into water supply systems, large-scale floods or terrorist attacks (e.g., biological weapons). The microbiological quality of water plays a significant role, which is directly related to the potential health risks associated with harvested rainwater (including rainwater stored in the tanks). Microbial contamination is commonly found in rainwater. However, in the literature, detailed results of qualitative and quantitative microbiological assessments are sparse and remain unexplored. Therefore, the aim of this study was to investigate and analyze changes in the microbiological quality of roof-harvested rainwater stored in the tanks, depending on the collection conditions (type of roof surface), storage duration and season. Authors elucidate that conditions such as storage duration, the season in which rainwater is collected, the roof-like surface types and morphology of the catchment area highly affect rainwater quality. This study showed that rainwater harvested from a galvanized steel sheet roof had the best microbial quality, regarding the lowest number of bacteria, while rainwater from a flat roof covered with epoxy resin was the worst. Further, it was detected that rainwater collected in autumn and spring obtained the best microbiological quality. Moreover, a decrease in the number of bacteria was observed in correlation to storage duration. The water became sanitary safe after six weeks of storage at 12 °C. Its use for purposes requiring drinking water quality before six weeks of storage required disinfection.

“…To improve social welfare, the government organizes or creates a platform to make its people prosperous so everyone can feel justice (M. T. Rahman, 2011). One example is establishing an institution, namely an orphanage (Amos, 2020;Carr, 2020;Defar, 2021;Wade, 2020). The government establishes orphanages to accommodate children born or living less fortunate; then, they are adjusted and fostered there to become qualified, educated human beings like children who live with their original parents.…”

The research conducted by the author aims to understand, analyze and describe the role of orphanages in the welfare of abandoned children. In addition, this research aims to find out what programs and things can encourage and hinder the welfare of neglected children. This study uses a qualitative method. The data in this study were obtained from various sources: observation, interviews, and literature studies. While the types of data obtained are primary data and secondary data. Studies and literature use concepts and theories related to research. From the results of this study, the authors found that the Mutiara Bani Solihin Orphanage has an essential role in the welfare of neglected children. Orphanages try to replace the position of parents who have to educate and raise their children. The orphanage carries out various programs and regulations for the welfare of the foster children, such as formal and non-formal education. Several factors encourage orphanages to prosper foster children there, namely the existence of adequate facilities and infrastructure, the support of the local community, and caregivers with high social spirits. The factor that hinders the welfare process for foster children there is the unclear administration of children. This happens because many parents leave their children without providing a complete identity, so sometimes the orphanage has difficulty registering their children for school.

“…Newly planted trees and shrubs require irrigation, as may established plants during drought, particularly under urban conditions of elevated temperature and vapor pressure deficits. Irrigation—in concert with improved soil quality from amendment with organic wastes—can dramatically increase yields and precocity in urban agroecosystems in general (Amos et al., 2020) and, potentially, the ability of UAF to address food insecurity and low access to nutritious foods in urban neighborhoods. However, municipal sources of water may not be accessible, and, even if they are, the use of treated, potable water for irrigation is neither sustainable nor cost effective (Lovell, 2010).…”

Urban landscapes combining trees and crops-urban agroforestry (UAF) systemsmay offer greater ecological and cultural benefits than annual cropping systems.Interest in UAF is growing, as evidenced by an increasing number of built projects and articles in the popular press and the academic literature on the subject. However, the practice of UAF appears to far outpace research on its scientific underpinnings or its design. Developing sustainable, resilient UAF sites can be challenging because of biophysical and sociocultural conditions unique to the city; however, cities offer opportunities not found in rural environments including the potential to close open nutrient loops between consumers and sites of food production.We argue that these biophysical and sociocultural challenges and opportunities can be best addressed through an evidence-based approach to the design of UAF systems and a complex ecological aesthetic design language integrating theory, principles, and practices from urban agroecology and allied fields, environmental psychology, and landscape architecture. The resulting multifunctional UAF systems would be socially sustainable and equitable and promote the circular metabolism of the city. Drawing on a purposive review of literature from these disciplines, we propose a preliminary framework consisting of 14 guidelines and complementary principles and strategies for the design of multifunctional, culturally preferred UAF and offer recommendations for future research.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
