Construction of the Uganda Makindye Kalidubi Drainage Channel Improvement Project Undertaken by China Railway No.10 Engineering Group Commences

en.Wedoany.com Reported - On November 9, China Railway disclosed that the Uganda Makindye Kalidubi Drainage Channel Improvement Project, undertaken by China Railway No.10 Engineering Group, has officially commenced. The project is located in Sabagabo, Makindye Division, Kampala, Uganda, with a contract duration of 18 months. It mainly involves 3.2 km of channel dredging, riverbed foundation replacement, reinforced concrete lining, and the construction of supporting box culverts. Upon completion, the project will improve local drainage and flood conveyance conditions and alleviate the impact of waterlogging during the rainy season on road traffic and the daily lives of nearby residents.

The Kalidubi channel alignment is significantly affected by seasonal heavy rainfall, and the existing channel has insufficient drainage capacity, making it prone to waterlogging and poor drainage during the rainy season. Standing water in some low-lying areas affects residents' daily travel and impacts the operation of roads and other infrastructure along the alignment. This project carries out comprehensive improvement of the existing channel by removing sediment deposits, treating the riverbed foundation, and constructing concrete lining structures.

The main works include 3.2 km of channel dredging and foundation replacement. Channel dredging mainly removes sediment deposits from the riverbed to restore the channel's flow cross-section; foundation replacement addresses the original riverbed foundation conditions to provide a basis for subsequent lining construction. Reinforced concrete lining will be used for channel structural improvement to enhance the structural stability of the riverbed and side slopes and reduce the impact of water flow scouring on the channel cross-section.

The supporting box culvert works are another important construction component of this channel improvement project. As enclosed water conveyance structures, box culverts can be used for water flow conveyance at road crossings and related drainage nodes, forming a continuous drainage pathway when connected with the main channel. Channel dredging, foundation treatment, concrete lining, and box culvert construction together constitute the main works of the project, involving comprehensive renovation of the main channel and drainage facilities along the alignment.

The first phase of the project was awarded in June 2026 to the Africa Branch of China Railway No.10 Engineering Group, with the project owner being the Makindye Sabagabo Municipal Council. After winning the bid, the project team carried out site surveys, optimized the construction organization plan, allocated materials, equipment, and labor resources, and advanced preparations for commencement, including submission of construction plans for review, construction of temporary facilities, and technical briefings. Following the official commencement, the project has entered the main construction phase, with a contract duration of 18 months.

Upon completion, the improved channel will enhance regional drainage conditions, increase the channel's flow conveyance and flood drainage capacity during heavy rainfall, and reduce the impact of waterlogging along the alignment on road traffic and residents' lives. Once the supporting box culverts and the main channel works are put into operation, they will jointly undertake regional stormwater conveyance tasks and improve drainage conditions for relevant roads and surrounding infrastructure in Makindye Division.
