Requested Services:

The Government of the Hashemite Kingdom of Jordan has arranged finance from the Government of the Federal Republic of Germany through the German Development Bank KfW. The services requested under this assignment refer to the preparation of a feasibility study for the replacement of the Azraq – Khaw conveyor pipeline and the extension of the Azraq wellfield.
