The consortium of IMDC, CDR International, Rebel Group and ADK has prepared the Feasibility Study for Deferred and Performance Based Maintenance Dredging of the Odaw Channel and Korle Lagoon in Ghana. In recent past, severe flooding occurred in Accra. The overall project objective is to contribute to achieving 1 in 10 years flood protection (T10) in the primary Odaw channel system, by preparing a ready-to-tender Performance Based Contracting (PBC) investment that will be financed as part of the broader World Bank GARID programme.
