Oshogbo Ede Water Expansion Scheme, Nigeria


We led the planning, design, construction, material shipments, specialist plant & equipment procurement on the £120m and largest water supply scheme in Africa, with improved operational efficiencies, timely stage completions and cost savings.

At the time the £120m Oshogbo – Ede water expansion scheme in Osun State, Nigeria was the largest water supply project in Africa, providing 35,000,000 galls/day of potable water to a population covering 5000 sq.km. Main contractor Costain (West Africa) employed a workforce of 2500 in the construction of the new Erinle River dam, 35mgd water treatment works, 60no concrete storage reservoirs and 800km of pumping mains and gravity pipelines.

As Construction Project Manager we held overall responsibility for co-ordinating site construction works on the dam, water treatment works, reservoirs and pipeline sections; shipments of specialist plant, equipment and materials.

We communicated with the design consultants and determined the construction programme accordingly; directed the 4no Section Managers and Construction Superintendent in the strategic deployment of labour, plant and materials; and instructed the Procurement Manager on the requirement for local and overseas supplied specialist plant, equipment and materials.

Having close operational control over the design, programme and resources we were able to achieve optimal efficiencies in site construction activities, to realise early area completions and cost savings.
