This document describes a case study of a Hungarian development project that improved access to water in Uganda. The project provided solar-powered water purification systems called "Oasis water towers" at three schools near the Rwamwanja Refugee Settlement, benefiting refugees and local communities. The project selection process was transparent, prioritized environmental and social considerations, and selected a private sector partner based on established criteria. The systems can produce over 144,000 liters of purified water per day and were designed to be resilient, inclusive, and self-sustaining. The project demonstrated good infrastructure governance principles throughout its lifecycle.
