Water conservation and a decreased reliance on municipal water sources are just two advantages of rainwater gathering, which is an environmentally friendly practise. However, conventional rainwater collection techniques frequently need a lot of space, which prevents their use in densely populated places. In this study, a ground-breaking solution is introduced: a wall-mounted rainwater collecting system created expressly to maximise space utilisation without sacrificing efficiency. The study includes material selection, installation techniques, and performance analysis and focuses on the creation and assessment of this novel system. Additionally, the quality of the rainwater collection is evaluated. The outcomes show the wall-mounted system's significant benefits, including effective space utilisation, performance on par with traditional techniques, and improved water quality. These results not only promote sustainable water management techniques but also provide crucial information for the installation of wall-mounted rainwater collecting systems in urban settings. This study emphasises the potential of wall-mounted systems to increase the uptake of rainwater harvesting, hence improving water sustainability, and easing the burden on municipal water resources by overcoming space constraints and utilising vertical surfaces.
