Half of Karachi's 12M population has no piped water supply. Distribution to the few dwellings that do have plumbing tends to be intermittent.
Self has devoted almost 10 years of his 30 year overseas career to this project. Completion of the first half of the £250M scheme - one of the world's largest new water schemes - brings bulk supplies 150km from the River Indus and will do much to reduce the water shortage.
The project includes 50km of bulk supply canal, 61km of 3.2m2 reinforced concrete culvert, 7km of twin DN1820 steel pipelines, three massive pumping stations, a treatment plant and a reservoir.
Self fulfilled three roles as the project manager for the Development Wing of Karachi Water & Sewerage Board. He was chief resident engineer for 21 separate contracts with a team of expatriate and Pakistani site supervisors. As engineering and project management advisor to the KWSB's project director he was closely involved in managing the grant and loan agreements with the international donor agencies funding the scheme.
