People use water from surface water bodies, such as freshwater streams, reservoirs, rivers, etc. with or without treatment, during the rainy season (June to September). But during the dry period, these sources become limited and scarce creating acute water crisis in the recent past. Presently different NGOs and governmental bodies are promoting technical supports for adopting new technology including the construction of underground water reservoir (UWR) for storing water in the rainy seasons. In most cases, these prototype underground water reservoirs serve as merely mono-functional service utility in spite of the huge construction cost and resource-investment involved. The study investigates a case study to show how infusion of new function with these UWRs can validate the investment of resources to ensure sustainable operation, maintenance and prolonged service life. The study area, an orphanage called Megher Bari, operated by Bidyanando Foundation in Naikhongchori, Bandarban, had a similar case of a water crisis with a proposal of UWR design intervention. During the predesign study, analysis of surrounding context, collection of the meteorological data and focus group discussion was conducted to find out the possibilities of the new functions. The study thoroughly revealed some design possibilities, based on which design decisions were made to infuse new purposes; in the UWR prototype for the hilly areas ensuring its easy operation and maintenance throughout the year.
