Sandford International School, a prominent institution in Addis Ababa with 1,027 students and 304 staff, played a key role in advancing the Ethiopia 2025 WASH Survey. As part of Project 12, the Needs4Water team assessed water access, sanitation conditions, and hygiene practices on campus.

Dr. Tsion Assefa, a trusted associate of the project, supported the technical effort by conducting on-site water quality testing. This hands-on analysis ensured accurate data on water safety while also contributing to capacity-building through local expert involvement.
