The Zambezi River Authority (ZRA) has awarded the tender for the rehabilitation of the Kariba Dam spillway, to a consortium comprising GE Hydro France and Freyssinet International.

The spillway is a major component of the Kariba Dam Rehabilitation Project (KDRP) and the contract is valued at $53,684,000.00.

The loan and grant financing committed to the KDRP project by the World Bank and the African Development Bank are primarily funding the spillway rehabilitation works and the supervision costs of both the spillway refurbishment and plunge pool reshaping works contracts.

Eng. Munyaradzi Munodawafa, Chief Executive of the ZRA, confirmed that “Together with the plunge pool reshaping, the refurbishment of the spillway will ensure the long-term safe operation of the Kariba Dam for many more years and the dam’s continued contribution to Zambia and Zimbabwe’s energy security and economic prosperity.”

“The spillway will be refurbished over a timeframe of four years and is expected to be commissioned by the end of 2023,” he added.

The contractor is expected to mobilise to the site gradually over ten months having started in September.

Spillway rehabilitation does not offer many job opportunities

The spillway refurbishment works are expected to generate only a limited number of jobs for unskilled and semi-skilled workers. However, the works will stimulate local businesses, given the influx of people into the area.

The spillway works, like the plunge pool works, will not require the relocation of people from the project site or adversely affect water levels in the reservoir and fauna and flora in the dam area.

The Kariba Dam Rehabilitation Project (KDRP) is funded by four co-operating partners, namely the European Union, the World Bank, the African Development Bank, and the government of Sweden, along with the Zambezi River Authority.

The Authority operates, maintains and manages the Kariba Dam on behalf of the governments of Zambia and Zimbabwe, which have equal ownership of the corporation.

ZRA was established in October 1987 by parallel legislation in the parliaments of Zambia and Zimbabwe under the Zambezi River Authority Acts. Its primary functions include the operation, monitoring and maintenance of the Kariba Dam complex.
