Urbanization and population growth are accelerating across the globe, putting immense strain on water distribution systems, especially in densely populated urban areas and high-rise residential buildings. This thesis responds to the critical need for more sustainable and efficient water management solutions by investigating advanced technologies and system designs that optimize water distribution. Specifically, it focuses on the integration of autoclave systems, pump technologies, and renewable water resources to ensure consistent water supply across multiple floors, even when municipal water pressure is insufficient. The core of this research lies in developing a holistic approach to water distribution in residential buildings, using a detailed case study of a six-story structure.
