By 1983, the Tripartite Permanent Technical Committee (TPTC) was formally established to discuss matters pertaining the water resources of common interest to the three countries. At the same time, Joint Permanent Technical Committees (JPTC) were formed between each of the countries to deal with water resources of common interest to any two of the countries. In 1992 the JPTC between Swaziland and South Africa was converted to the Joint Water Commission (JWC) through the signing of the Joint Water Commission Treaty. The TPTC, JPTC and JWC are chaired by the heads of Departments for Water on a rotational basis. They comprise of at least three members from each country and each country can co-opt several advisors from various Departments in the country. This promoted inter-sectoral governance. Formal meetings are held at least two times a year or as frequent as required. Funding for attending the meetings is covered in each countries budget.
In 1992 South Africa and Swaziland signed the Treaty on the Development and Utilisation of the Water Resources of the Komati River Basin that paved the way for the Komati River Basin Development Project, a joint project between the two countries. Mozambique who was experiencing civil war at the time gave consent to the Project (Pigg’s Peak Agreement).
In 1998, the Southern Africa Development Community (SADC) signed the SADC Protocol on shared watercourses, calling for cooperation between riparian states on shared watercourses and the formation of watercourse institutions to facilitate cooperation between riparian states.
In 2002, the three countries signed the Interim Inco-Maputo Agreement. This process brought about coordinated water resources management and development in the Komati River Basin. Information was shared in these forums on water resources development plans and assessments, and information on floods and droughts as well as water resources monitoring. An example of this cooperation was seen during the 2000 floods that devastated Mozambique.
South Africa was very instrumental in assisting flood victims. Cooperation between the countries also made it easier for the countries to obtain funding for joint water resources development projects and programs.
In 2002, TPTC established the Incomati Systems Operation Task Group (ISOTG) to formulate operating rules for the Incomati River System. In their recommendation, ISOTG took the concept of inter-sectoral governance to the local level. It recommended the formation of the Komati Joint Operations Forum (KJOF) as a forum comprised of users in the Komati River Basin to advise the Komati Basin Water Authority (KOBWA) that manages the Komati River on the operational aspects of water resources management.
