    BADASA DAM PROJECT

BADASA CORE VIEWThe Contract to undertake design review and construction supervision of Badasa dam was awarded in 2009. The project site is in Marsabit Town, Marsabit county. The project comprises of construction of the following major works:

  • An embankment of 52m height on Buji River and located within Mount Marsabit forest reserve, Scour and Intake works, Diversion Culvert,
  • Raw Water Pumping Station,
  • Water Treatment Plant,
  • Treated Water Pumping and Booster Stations,
  • Treated Water Rising Main, 250mm diameter and about 10km long and Storage Facilities of capacity of about 3,000 m3.

Water from the proposed Badasa Dam reservoir will be pumped to the proposed treatment works against a static head of 50m and through an intake pipe of 250mm diameter and 300m long. From the clear water tank at the treatment works, water will be pumped against a static head of 430m with a booster station in between. Total length of clear water rising main is 9.7km. Additional storage of 3,060m3 will be required to augment the existing storage of 565 m3. Existing distribution network will be expanded in another phase of the project.

Tendered project cost: US $ 30 million (Ksh. 2.4 Billion).

KORU DAM ON RIVER NYANDO, KENYA

Koru dam site photoA Feasibility Study, Preliminary and Detailed Designs and Environmental Impact Assessment for the proposed Koru dam. The dam will principally control the perennial flooding of the Nyando plains. Use of the dam to supply water to Kisumu City and other surrounding centres, irrigation and Hydropower use are being considered. Consultant commenced the assignment at the beginning of February, 2009.

The dam site is within 5-15 km upstream of Muhoroni Town. Previous studies had put the dam at 81 m high and a capacity of 250 million m3. This sizing was reviewed during the Study to 57m.

The principal use of the dam, when implemented, will be for Flood Control, Irrigation, power generation and Supply of water to Kisumu City, towns and environs on the downstream of the dam.

The scope of the study encompasses:

  • Feasibility Studies of the potential dam sites within the area and selection of the most viable site based on technical and economic considerations.
  • Preliminary Studies and designs of the most viable dam site.
  • Detailed Designs and preparation of Tender Documents
  • Environmental and Social Impacts Assessment (ESIA)

PROPOSED NZOIA DAM

Nzoia dam siteA feasibility, preliminary and final designs as well as socio –economic and environmental impacts associated with construction and operation of the Nzoia Multipurpose dam on Nzoia river, Lugari, Kenya.
The construction of Nzoia Multipurpose Dam in the middle catchment on the River will mitigate against floods and ensure sustained flow levels in the river during dry periods enabling irrigation throughout the year. This reservoir would also supply water for domestic and industrial uses, generate hydroelectric power and perhaps offer opportunities for fishing and water-based recreation. By also acting as sediment traps, the dam will also reduce the sediment loading downstream.
The dam would be a rock fill dam having the following elements;
  • A 60m high embankment;
  • An open channel spillway on the right abutment controlled by a 150m wide ogee crest weir and terminating in a stilling basin;
  • Four diversion culverts, three of which will house penstock pipes;
  • A free standing intake tower with bridge access to the dam embankment;
  • A power generation plant (16MW) located 100m downstream of the embankment edge;
  • Water treatment plant with a capacity of 41,804m3/day.
