Water Storage For Irrigation - Dams

BACKGROUND

Irrigation development is identified as one of the key enablers of development to attain vision 2030. Water storage for irrigation is largely untapped and the estimated basin outflow in Kenya is 24.6 BCM out of which 12.4 BCM goes to waste through flood flow and can be stored for irrigation development.

The government under the Jubilee manifesto targeted to put 1 million acres under irrigation within a period of 5 years from 2013.To realize this, there is need for water storage for irrigation due to reduced river flows and increased water demand for domestic and industrial uses hence the need for dams as a storage means for water.

INTRODUCTION

Under the Boards strategic plan (2014-2018), Improvement of water availability through water conservation by construction of pans and dams was one of the activities targeted to be implemented. In line with this, the NIB identified and prioritized construction of the following dams of total capacity 8.5 B CM targeting to put 1.2 million acres under irrigation.

  1. Construction of Thiba dam project with a capacity of 15 M CM to expand Mwea irrigation scheme by 35,000 acres
  2. Construction of Thuci dam project with a capacity of 23 M CM to enlarge KagaariGaturi irrigation scheme to a total of 17,000 acres
  3. Construction of Rhabura and Thiririka dams to put 5000 acres under irrigation.
  4. Construction of Lowaat Dam in Turkana County with a capacity of 348 M CM to put a total of 37,500 acres under irrigation around Morulem, Lokubae and EleleaIrrigation schemes and provide domestic water to residents of Lokori, Lokachura and Katilia locations within Lokori division.
  5. Construction of Radat Dam in Baringo County with a storage capacity of 267 M CM to enlarge Perkerra irrigation scheme to a total of 5,000 acres.
  6. Construction of Kyakivai and Kaiti/Ngomano dams in Makueni county to put 10,000 acres under irrigation.
  7. Construction of Gogo Dam in Migori with a capacity of 464 M CM to put 67,500 acres.
  8. Construction of Lower Subukia Dam with a capacity of 1 million cubic metres to irrigation 2500 acres.
  9. Construction of the High Grand Falls dam with a capacity of 5.4 B CM targeting to put over 650, 000 acres under irrigation in Kitui, TharakaNithi, Tana River and Garissa counties

Implementation Progress

Due to the high costs of the projects, the National Irrigation Board, was directed by the Ministry of Water and Irrigation to commence the implementation of most the projects through Engineering Procurement Construction and Finance (EPC-F) models except Thiba dam which is being financed both by the Government of Kenya and Loan from JICA

The details of the dams and status is as follows;

 THIBA DAM

Thiba dam is located in Kirinyanga County in Mwea Constituency. The project involves construction of 15 million cubic water storage across Thiba River which will enable the expansion of the Mwea Irrigation scheme by 35,000 acres. The contract for the works was awarded to Strabag company of Germany for a construction period of 36 months. The commencement date was March 2018 and the works are expected to be completed by March 2021.The progress of works is currently at 22% which is satisfactory and all the PAPS have been compensated.

RADAT DAM

Radat dam is located in Baringo South Constituency in Baringo County. The project targets to expand the existing Perkerra Irrigation Scheme by 25,000 acres once completed and has a storage capacity of 267 million cubic metres. The project is being implemented by the National Irrigation Board(NIB) through the Engineering Procurement Construction and Finance model and CMC DI RAVENNA Company Ltd of Italy were awarded at their quoted bid having emerged with the highest technical and financial score pending clearance from the National Treasury and the Attorney. The project also requires cabinet approval and the necessary documents have been forwarded to the PS for irrigation to facilitate fast-tracking of the process however due to recent developments indicating the firm could be declared bankrupt and not in a position to carry out the works, NIB has sought confirmation from the firm on its financial status/liquidity. The firm responded and denied this position and NIB plans to involve the National Treasury to carry out a second due diligence.


LOWAAT DAM

Lowaat dam is located in Turkana East Constituency in Turkana County. The project targets to expand the existing Lokubae, Elelea and Morulem irrigation schemes by 35,000 acres once completed and has a storage capacity of 348 million cubic metres. It will also provide domestic water to an estimated population of 20,000 residents and generate 15 MW of power. The project is being implemented by NIB through the Engineering Procurement Construction and Finance model and China International Water and Electric group were awarded with a bid having emerged with the highest technical and financial score pending clearance from the National Treasury and the Attorney General. The project also requires cabinet approval and the necessary documents have been forwarded to the PS for irrigation to facilitate fast-tracking of the process.

THUCI DAM

Thuci dam is located in Runyenjes Constituency in Embu County. The project targets to expand the existing Kaagari Gaturi irrigation schemes by 10,000 acres once completed and has a storage capacity of 23 million cubic metres. It will also provide domestic water to an estimated population of 10,000 residents and generate 5 MW of power. The project is being implemented by NIB through the Engineering Procurement Construction and Finance model and Elevolution Engenharia, SA /Weihai International Economic &Technical Cooperative Co. Ltd of Portugal was awarded the bid having emerged with the highest technical and financial score pending clearance from the National Treasury and the Attorney General. The project also requires cabinet approval and the necessary documents have been forwarded to the PS for irrigation to facilitate fast-tracking of the process.

GOGO DAM

Gogo dam is located in Nyatike Constituency in Migori County. The project targets to put 25,000 acres in Nyatike and the surroundings once completed and has a storage capacity of 348 million cubic metres. It will also provide domestic water to an estimated population of 30,000 residents and generate 25 MW of power. The project is being implemented by NIB through the Engineering Procurement Construction and Finance model and CGCOC of China has been notified of award pending clearance from Attorney General and Treasury. The National Treasury has requested the Chinese government to consider financing the project. It also requires cabinet approval and the necessary documents have been forwarded to the PS for irrigation to facilitate fast-tracking of the process.
