Construction of Water Control Structures

The Lake Chad Basin is one of Africa's most ecologically significant and economically vital water systems, supporting the livelihoods of tens of millions of people across Nigeria, Niger, Chad, and Cameroon through farming, fishing, and pastoralism. However, erratic rainfall patterns, upstream damming, and the impacts of climate change have led to significant fluctuations in water levels across the basin, causing seasonal flooding in some areas and severe water scarcity in others. The Chad Basin Development Authority (CBDA) commissioned Blue Sea Services Limited to construct water control structures at Jere in Borno State as part of a broader strategy to regulate water flow, prevent flooding, and support irrigation for agricultural communities in the basin. Blue Sea Services Limited is executing this technically demanding hydraulic engineering project with a team of experienced civil and water resources engineers. The scope of work includes the construction of weirs, sluice gates, and channel infrastructure designed to regulate and direct water flow across the agricultural landscape of Jere, protecting farmlands from flooding during high-flow periods while ensuring that water is retained and available for irrigation during dry seasons. Detailed hydrological surveys, structural design, and environmental impact assessments were conducted in the planning phase to ensure that the structures are designed to withstand extreme flow conditions and deliver long-term performance. Construction materials and methods have been selected to ensure durability in the challenging semi-arid environment of Borno State. This project, when completed, will have a transformative impact on agricultural productivity and food security for farming communities in Jere, protecting their livelihoods from climate-related water variability and enabling year-round cultivation through reliable irrigation support.
