CONTRACT FOR HIRING A CONSULTANCY FIRM FOR REVIEW DESIGN STUDY FOR CYOHOHA HILLSIDE AND MARSHLAND
The main objective of this assignment is to undertake the design review and modifications to the existing study of Cyohoha North Hillside & Marshland Irrigation and Drainage Project to irrigate at least 3,000 ha net from the 5,000 ha gross area along the south side of the valley between Akanyaru River and the upstream end of Cyohoha Lake, not exceeding 50m in elevation above the lake. Based on this, prepare the detail design and tender documents for construction works of the modified irrigation system and infrastructures.
The Cyohoha North Irrigation and Drainage Project has a total gross command area of 3,400ha, sub divided in four Blocks, for which feasibility and detail design studies were prepared. The project work is constituted by the key salient features as follows:
- Each block has 2 pump stations pumping to reservoirs located at an upper and a lower zone.
- A total of 3,400ha of irrigation systems consisting of 40% sprinkler irrigation (for high-pressure zones) and 60% pipe-flow hydrants (for hose or drip irrigation in low-pressure zones);
- A long regulating weir structure has been proposed across the Akanyaru River valley floor just downstream of the confluence with Murago Marsh, to increase and control the level of water in the river and provide water in lake Cyohoha
