Water supply from the Lesotho Highlands water project to South Africa has been stopped for nearly a month because of tunnel repairs on the South African side of the water transfer tunnel.

The South African Department of Water Affairs and Forestry and

Trans-Calendon Tunnel Authority (TCTA) said water supplies were unlikely to resume until the end of October.

TCTA spokesman Willie Croucamp said erosion protection work needed to be carried out at the Ash River outfall tunnel near Clarens in the Orange Free State.

South Africa will compensate Lesotho for the loss of revenue from water exports to South Africa. The Lesotho Highlands project has been supplying water to South Africa since January 1998. Lesotho buys electricity from South Africa in return.
