About Us
The Agency serves Kitui, Makueni, Machakos, and Kajiado Counties, first as Tanathi Water Service Board on 4th June 2008 and currently as Tanathi Water Works Development Agency from 3rd May 2019. There are many milestones and accomplishments over time that remain vital to us. These include the design of Thwake Multi-Purpose Dam and Reservoir, becoming part of the National Government Major Water Development Project, construction of the Masinga-Kitui Water Supply Project, and rehabilitation of Yatta Canal and Mavoko Drinking Water Project.
