The Addis Ababa Water and Sewerage Authority (AAWSA) is a monumental, autonomous municipal enterprise mandated with the absolute responsibility of providing potable water and sanitary services to the millions of inhabitants of Ethiopia’s capital. Established in 1971, AAWSA serves as the absolute lifeblood of the metropolitan area, managing the complex extraction, treatment, and distribution of water from massive reservoirs like Legedadi, Gefersa, and Dire. The authority operates incredibly vast infrastructure, managing a network of over 400,000 domestic and industrial connections and several high-stakes wastewater treatment plants, including the modern Kaliti facility. AAWSA is currently executing a multi-billion Birr expansion project to meet the demands of Addis Ababa’s explosive urban growth, focusing heavily on groundwater development and the revitalization of old pipe networks to reduce non-revenue water loss. Beyond distribution, AAWSA has aggressively digitized its customer interface through mobile payment integrations with Telebirr and CBE Birr, fundamentally modernizing the utility billing cycle. They maintain a 24-hour emergency response team for leak repairs and water quality monitoring. Their unwavering commitment to urban sanitation and public health makes them the absolute foundational pillar of the capital city’s commercial and residential viability.
