Project General Description

The Kariba Dam Rehabilitation Project involves the rehabilitation of the Kariba Dam infrastructure by reshaping the plunge pool and rehabilitating the spillway. The Plunge Pool will be reshaped in order to dissipate energy from the spilled water thereby reducing the energy on impact and hence bedrock erosion which could undermine the dam foundations, leading to dam failure. The project will rehabilitate the spillway gates to avoid possible jamming in the open or closed positions both of which would result in dam failure and catastrophic regional loss of lives, livelihoods, assets and power. The project will also assist the Zambezi River Authority secure the long-term safety and reliability of the Kariba Dam complex and to forestall a potential dam failure that could disrupt commerce and livelihoods in nine southern African countries (Zambia, Zimbabwe, Malawi, Mozambique, South Africa, Botswana, Namibia, Lesotho and Swaziland) should the dam fail. The project comprises three main components, namely : (i) Plunge Pool Rehabilitation, (ii) Spillway Refurbishment and (iii) Institutional Project Support.

Project Objectives

The objective of the project is therefore to secure the technical integrity of the Kariba Dam complex for its safe operation to enable continued delivery of water for sustained power generation by the Kariba North and South power stations. At the same time, the project will forestall the potential of the dam failure that could occur if no action is taken to urgently reshape the plunge pool and stop its encroachment on the dam foundations, and to rehabilitate and modernize the spillway infrastructure.

Beneficiaries

Republics of Zambia and Zimbabwe will be the direct beneficiaries of the rehabilitation. The jointly owned Zambezi River Authority (ZRA) will benefit from securing the Kariba Dam and the national power utilities (Zambia Electricity Supply Company (ZESCO) and Zimbabwe Power Company (ZPC) will benefit from improved security associated with continued operation of the dam. Benefits will accrue directly within the regional context of the Zambezi River basin, particularly to the downstream riparian states of Mozambique and Malawi.
