Independent Drainage System

The Independent Drainage System of Eko Atlantic City

During the design stage of Eko Atlantic City, it was apparent that the road systems within the City would require an independent drainage network to ensure the proper evacuation of water off the road surfaces.

To be able to create an independent drainage network there needed to be a design for a canal system running throughout the middle of Eko Atlantic City. This canal system would receive all the water that flowed from the City's roads into the underground drainage network.

The solution conceived met all the criteria required for an independent drainage network. Absolutely none of the water collected in the City's roads would flow into the existing drainage networks of Lekki and Victoria Island.

Today, the drainage network in Eko Atlantic is already proving to be effective. The road network in Eko Atlantic City has yet to be inundated by rainwater even during heavy rain storms.

How the Drainage Network in Eko Atlantic City Is Built

Building the drainage network in Eko Atlantic City is a precise task that is repeated numerous times throughout the project.

To begin, concrete pipes are fabricated in the pipe factory located in Eko Atlantic City. Stormwater drainage pipes in the pipe factory vary in size from 30cm in diameter to the largest being 150cm in diameter.

When the pipes come out from their mould they are left to cure for 3 weeks to allow the pipes to achieve full design strength.
