The Government of Ghana has received financing from the World Bank toward the cost of the Greater Accra Resilient and Integrated Development (GARID) Project and intends to apply part of the proceeds toward payments under the contract for the Construction of 3 No. Sand Traps in the Odaw Channel and South Kaneshie tributary. For this contract, the Borrower shall process the payments using the Direct Payment disbursement method, as defined in the World Bank’s Disbursement Guidelines for Investment Project Financing. The Ministry of Works, Housing and Water Resources invites sealed bids from eligible contractors for the - Construction of 3 No. Sand Traps in the Odaw Channel and South Kaneshie tributary. The project involves the construction of three sand traps within the Odaw lined Channel and its main urban tributaries, with the goal of reducing sediment accumulation, increasing the hydraulic efficiency of the watercourse, and decreasing the frequency of dredging operations. This intervention is part of a broader maintenance and rehabilitation program for the Odaw River Basin, which plays a key role in flood risk mitigation in the city of Accra. The three selected sites for the installation of the sand traps are: downstream of Caprice Bridge, near the confluence with the Onyasia Stream; downstream of the lower Nima drain confluence; and on the South Kaneshie channel, downstream of the Mataheko confluence. The site selection was based on several criteria, including sediment accumulation, accessibility, space availability, environmental and social impact, and proximity to sediment handling facilities. The sand traps are designed to reduce water flow velocity, enabling the settlement of target particles (fine sand and gravel). The dimensions vary depending on the site: Caprice (25x55x2 m), Nima (35x50x2 m), and Kaneshie (15x24x0.7 m), with respective storage volumes of approximately 2,750 m³, 3,500 m³, and 252 m³. To enhance sedimentation efficiency, baffle walls are included in each trap, dividing them into multiple flow-slowing chambers. Regular dredging of the sand traps will be carried out using a remote-controlled floating dredge equipped with an electric submersible pump. The extracted material is temporarily deposited in nearby storage areas, where it is dried and then either sold to off-takers or transported to a landfill. The dredging equipment, including 200 m³/h pumps and a combination of floating rubber pipes and buried HDPE pipes, is designed to maximize operational efficiency and mobility. Each site will also be equipped with a mobile diesel generator, waterproof electric cables, and a maneuvering area suited for three-axle trucks. The contract period for the execution of the entire project is set at nine months.
