In 1992 Resolution 1155 was issued, which was considered a turning point in the course of structuring the water sector in Sudan, as it led to the disintegration of the Water Authority and the formation of the National Drilling Company / and the National Construction Company / and the National Company for Manufacturing and Management of Groundwater and Valleys, and the tasks of the National Water Authority were limited to developing public policies, strategies and national planning And overseeing federal and externally funded projects and national training tasks, and then state bodies established the decision to limit their tasks to managing existing water utilities, production and distribution of water, and a law was passed for each body through state legislatures. This decision weakened the interdependence of water cadres and their distribution to several sectors without an institutional relationship between them and In light of this decision, the following took place:
The National Water Authority was established and state bodies were established in 1994.
A decision was issued to establish the Public Authority for Water in 2007.
The Public Authority for Water was replaced and the Drinking Water and Sanitation Unit was formed in 2012.
