Mr. Taha Mohammed Al-Washali graduated on 21 December 2020. Find the link to his thesis here.
Taha AL-Washali is a water engineer from Yemen. Currently, he is a Ph.D. fellow in water supply engineering, working on developing tools and methods that enable water utilities to manage and minimize losses in water distribution networks, with a particular focus on intermittent supply.
Taha AL-Washali got his bachelor's degree in civil engineering from Sana’a University, Yemen, and got his master of science (Excellent) in water resources management from Cologne University, Germany. He joined the water sector from the first day of his bachelor graduation, and becomes more inspired about water by every day goes by. He started in a GIZ project, a project engineer at KFW national project, and later became a general director of the projects department in the national water supply and sanitation authority in Yemen. He worked in many projects for several governmental and international agencies, including GIZ, KFW, USAID, WHO, and OXFAM. He also contributed to several policies, strategies and key reports in the Yemeni water sector. In 2014, he joined academia starting in a project aiming to build the capacity of the Water and Environment Center at Sana’a University. Since then, his research interests focus on water supply efficiency, including water loss assessment, modeling and minimization, pressure management, leakage control, water meter accuracy, and apparent losses. Besides water loss management, interesting research includes real-time break-event detection, asset management, and benchmarking (PIs).
