The Lesotho Highlands Water Project (LHWP) is a bi-national Project between the Governments of the Kingdom of Lesotho (GOL) and the Republic of South Africa (RSA). The Treaty signed between the two governments sets out the structures that are required to implement the Project on behalf of the two governments.

The Lesotho Highlands Water Commission (LHWC) which consists of three delegates per country, is accountable and responsible for the implementation of the Project. LHDA is the implementing authority of the Project within Lesotho, whereas, the TCTA is mandated to raise funding for the part of the Project that is in RSA.

The LHWP comprises water transfer and hydropower generation components with associated ancillary developments.  The water transfer component entails the construction of dams and tunnels in Lesotho, enhancing the use of water from the Senqu (Orange) River and its tributaries by storing, regulating, diverting and controlling the flow to effect the delivery of specified quantities of water to South Africa, and utilizing the delivery system to generate hydro-electric power in Lesotho.

The major works of Phase I included the construction of the Katse Dam, the transfer and delivery tunnels, the ‘Muela Hydropower Plant and the Mohale Dam. The Phase II water transfer component comprises a dam at Polihali and a gravity tunnel that will connect the reservoir at Polihali with the Katse Reservoir. The envisaged hydropower component will comprise the Kobong Pumped Storage Scheme, or a similar scheme. The implementation of the hydropower generation scheme is subject to agreement on the outcome of a further feasibility study which is currently underway.
