The Treaty sets out the structures that are required to implement the Project on behalf of the two governments.
The implementation of the Project is managed on behalf of the Lesotho Government through its Ministry of Energy, Meteorology and Water Affairs by the Lesotho Highlands Development Authority (LHDA) while those sections which lie in South Africa are managed on behalf of the South African government through its Department of Water Affairs and Forestry by the Trans-Caledon Tunnel Authority (TCTA).
The two countries have established the Lesotho Highlands Water Commission (LHWC). Each country nominates its own representatives to the represent it in the Lesotho Highlands Water Commission . The Lesotho Highlands Water Commission is responsible and accountable for the Project. It acts on behalf of and advises the two governments and it is the channel of all government inputs relating to the Project. The LHWC appoints a Board of Directors which in turn appoints the Chief Executive. For the day to day running of the organisation, the Chief Executive is assisted by a team of executive members (EXCO) and Branch Managers.
