The Matabeleland Zambezi Water Project (MZWP) is an ambitious project being undertaken in the arid Matabeleland North province of Zimbabwe.The project seeks to end the perennial water shortages bedevelling Zimbabwe's second city of Bulawayo by bringing water from the mighty Zambezi river to the city.

[edit] The Project

The project can be classified as a Major Project. It is expected to cost US$600 million which is a huge investment by African standards. The project will consist of three phases as follows:

  • Phase One: Gwayi-Shangani Dam
  • Phase Two: Gwayi-Shangani Dam to Bulawayo Pipeline
  • Phase Three: Gwayi-Shangani Dam to Zambezi River Pipelne

[edit] Phase One: Gwayi-Shangani Dam

The Gwayi-Shangani dam is the first phase of the MZWP and is the core of the project. Commenced in September 2004 it is expected to provide a reservoir for this project. The dam will be located about 6km downstream of the confluence of the Gwayi river and Shangani river.
