GIBB was appointed to lead a multi-disciplinary team to carry out a pre-feasibility study to augment the Mgeni Water Supply System from large scale seawater desalination of 450 Ml/day.  The project output is a pre-feasibility report elaborating on a holistic approach to augment water supplies through seawater desalination.


Key Features
