Tanzania WASH sector stakeholders collaborated between March and May 2022 to develop this Country WASH M&E Roadmap. The initial vision, outcomes and activities outlined in the Roadmap were established during a workshop, held on 2–3 March 2022, and further refined during a second workshop, held on 28 April 2022. The Roadmap development process was facilitated by UNICEF Tanzania, in collaboration with the Ministry of Water, and with the support of Tanzania’s WASH sector stakeholders.
