CIVIL ENGINEERING DESIGN + INFRASTRUCTURE + ENERGY0.5MW Epe Interconnected Mini-Grid
Epe, Lagos State, Nigeria 2025 Land Size-10,00 sqm
In 2025, IHOD was appointed to design the stormwater drainage system for the Epe Solar Farm, engineering a comprehensive surface water management strategy to protect the site’s critical infrastructure and facilities against erosion and hydraulic damage, delivered within a focused one month programme.
Engineering the Solution
In response, IHOD engineered a reinforced perimeter drainage network, 600mm deep by 450mm wide, precisely dimensioned to intercept high velocity surface flow before it could threaten the solar arrays and supporting infrastructure. Integrated energy dissipation structures and erosion protection at every outfall ensure the system performs not just on paper, but season after season. The completed design was validated against the site’s full hydraulic demand and delivered to the client in December 2025, on time, within a focused one month program.
Where Precision Meets the Landscape
Confronted with a 10,800 sqm site falling at gradients of up to 12 percent in every direction, IHOD approached the challenge with the rigor of precision hydrology. Detailed hydrological modelling of the site’s stormwater behaviour revealed peak discharges of 0.25 cubic metres per second under design storm conditions, with seasonal runoff exceeding 11,000 cubic metres across Epe’s intense rainy season, among the heaviest rainfall belts in Nigeria.
