“…According to several studies, RWH is frequently utilized as an alternative source of water supply in both developed and developing countries, such as Poland (Stec & Zelenáková 2019), Turkey (Ertop et al 2023), Spain (Hernández & Morote 2019), the United States of America (Steffen et al 2013), China (Zhou et al 2023(Zhou et al , 2024, Ghana (Akuffobea-Essilfie et al 2020), Uganda (Ntale et al 2005), Kenya (Odhiambo et al 2022), Nigeria (Lade & Oloke 2013), Tajikistan (Daler & Rahmatilloev 2023), and Brazil (Ghisi & Schondermark 2013). Despite its application, rainfall variability (Awawdeh & Jaradat 2012), the quality of harvested water (Sazakli et al 2007), poor public perception (Mwenge & Taigbenu 2011), and a lack of commitment from politicians (Adugna et al 2018) are some challenges for the RWH system.…”

The assessment of the rainwater harvesting (RWH) potential in Hosaena City from medium to large public buildings is the main objective of the study. ArcGIS with Google Earth Pro was used to calculate the rooftop area of the selected building, and RWH from each category of public buildings was evaluated by considering rooftop areas, monthly rainfall, and runoff coefficient. The result shows that the highest amount of rainwater was harvested from the City Administration building in August (197.1 m3), whereas the lowest was collected from the Health Center building in December (1.8 m3). Additionally, the contribution of RWH from individual public buildings for each month was evaluated, and its values ranged from 0.073 to 1.8%. The comparison shows that Wachemo University, Nigist Eleni Comprehensive Hospital, a technical and vocational institute, and teacher training center buildings, could have a significant potential for rainwater storage, ranging from 1.56 to 28.41%. This implies that, besides saving a noteworthy volume of potable water, the excess rainwater can be stored and utilized for the later dry months. As a result, it is recommended that rooftop RWH in Hosaena be the best source of the city's water supply system to reduce the current water supply shortage.

Water conservation efforts are needed to meet increasing water demand (e.g., rainwater harvesting) to help maintain water and environmental sustainability in the present and future. The interdependence of the five components, which comprised 31 factors, was examined in a quick assessment of urban rainwater harvesting. This study aimed to evaluate the sustainability aspect that affects rainwater harvesting based on five sustainability factors. Stages of the research methodology; 1) Preparation of the research area and respondents, 2) Collecting data through survey methods using interview techniques to obtain related data, 3) Conducting data analysis and characterizing the sustainability of rainwater harvesting, using multi-aspect analysis based on developed factors and attributes, and 4) Using two scenarios reasonably sustainable circumstances urban rainwater harvesting variables, adapting management strategies should be developed based on the urban rainwater harvesting sustainability research, which is in a reasonably sustainable environment. The results show that the sustainability status of urban rainwater harvesting in the City of Balikpapan is relatively consistent, with an indicator of 44.77%. Institutional and technological infrastructure are aspects of low sustainability. To raise sustainability status to 'sustainable,’ then choose scenario number 1, that is a realistic scenario in which the 10 sensitive factors are upgraded, thereby raising the sustainability indicator to 65.52%. The most sensitive attributes to be improved are poor groundwater quality, availability of funding for rainwater harvesting, need for roof cleaning, need for collaboration between stakeholders, and reduction of conflict over taking water sources.
