Each NBI centre has its own governance structure involving a Council of Ministers of Water Affairs and a Technical Advisory Committee. Thus, the NBI structure involves the Nile-COM, which is the decision-making body for the Nile-SEC, the Eastern Nile Council of Ministers (ENCOM), which is the decision-making body for ENTRO and, similarly, the NEL-COM. Each of the Council of Ministers is supported by a Technical Advisory Committee comprised of two to three senior technical officials from the member states. Thus, Nile-TAC and NEL-TAC serve as advisory committees for the Nile-COM and NEL-COM, respectively. The Eastern Nile Subsidiary Action Team (ENSAPT) serves as the advisory committee for EN-COM. At national level, the ministry responsible for water affairs serves as the focal national institution for all NBI affairs.
