The selected contractor will procure, supply and install 620 kilometres of pipeline, pumping stations and storage tanks. The pipeline system will have capacity of 250,000 cubic metres a day of water and provide drinking water from an underground aquifer at Ghadames to over 1.25 million people living in Zauara, near the Tunisian border, Zawiya and small towns along the course of the pipeline. Water will also be used for irrigation.

Construction of the western network is expected to take 42 months. The consultants for phase 4 are the local Engineering Consultancy Office for Utilities (ECOU) and France’s Safege (MEED 3:1:03).
