Project Benefits

The expected benefits of dam from conception to commissioning include: -

  1. Locals and local firms will be directly involved during construction thus creating employment for area residents. Also through supply of construction materials and other services, more revenue will be generated.
  2. The construction of Thiba dam upon completion will provide water storage capacity of 11,200,000m3 to enable expansion of the area under irrigation to 35,000 acres as well as allow two crops per year.
  3. Increase total production of rice to approximately 160,000 tons thus increase income generated by farmers from sale of paddy rice to KES. 12 billion and also revenue generated from the production and value addition chain.

Procurement

The Civil Works was split into two procurement lots namely: -

  1. ICB Package I which consists of the civil works of Thiba Dam and Appurtenant structures, and
  2. ICB package II which consists of civil works of irrigation and drainage facilities.

Ongoing Activities

The contracts for the two packages were awarded signed. Currently, the following activities are ongoing:

  1. Mobilization of the contractors through purchase of office and construction equipment for both the Dam and the Irrigation area
  2. Establishment of the contractor’s camp and Engineers Offices
  3. Site survey and establishment of construction bench marks
  4. Geotechnical investigations and stock piling of construction materials
  5. Site clearance and grubbing

The progress of the project works for both the ICB Package I and ICB Package II is approximately 14% and 18% respectively.
Land compensation is also ongoing under the guidance of the National Land Commission that will focus on completing compensation for canal way leaves at the irrigation area.
