Freetown water supply system, Sierra Leone
A contract to rehabilitate the water supply in Sierra Leone’s capital city, Freetown. The contract will develop the scheme through feasibility studies, engineering and detailed design and construction using NEC target cost contracts to demonstrate value and cost for each stage. BAM’s part of the project will amount to approximately €25 million.
The Engineering Management Services Project for the Rehabilitation of Freetown Water Supply is entirely funded by the UK government through the Department for International Development (DFID).
Water supply in Sierra Leone is characterised by limited access to safe drinking water. Despite efforts by the government and numerous non-governmental organisations, access has not much improved since the end of the Sierra Leone civil war in 2002. In Freetown, taps often run dry.
The project includes the rehabilitation of Guma Valley water treatment works, including rehabilitation work to the Guma Valley dam scour valves, the intake and gravity pipe and the rehabilitation of the main water transmission network in the west of Freetown. The consortium will also target reducing the amount of leakage on the distribution network from 40 per cent to 25 per cent through a combination of improved leak detection and repair, and pressure/network management. Furthermore we will rehabilitate the secondary water distribution network, including 4 km of mains pipeline, 13 km of distribution network, 31 km of local supply network.
