Tono Irrigation Scheme, Ghana


We directed the early completion of this irrigation project in northern Ghana, to enable the timely planting of seasonal cash crops.

The Tono dam is one of the largest agricultural dams in West Africa, located in the Upper East Region of northern Ghana and serves as a place for year round farming. About 2,500 hectares of land is irrigated with water from the 2.5 mile long dam which serves seven villages in the Kassena Nankana District. The popular cash crops being cultivated by the project are rice, soya bean and tomatoes.

As Chief Engineer we were engaged to supervise the completion of the main irrigation and lateral canals that ran on either side of the banks of the Tono river, and grade the land such that the fields were suitably prepared for planting crops.

We directed construction of the canal embankments, their lining with a water proof membrane and precast concrete protection, the earth moving and land levelling operation, and trained local surveyors and supervisors to oversee the works.

There was a phased release of completed areas to local farmers to permit their planting of seasonal cash crops and sustain their livelihoods.
