Al Gharbia is the western region of the emirate of Abu Dhabi. This vast region spreads over an area of 60,000 square kilometers and borders with two neighboring countries of Saudi Arabia and Qatar. Al Gharbia is considered the nexus of traditional and modern Emirati society. The population of the region is expected to grow due to the different development being proposed in the area. Hence, sewage generated from this development is likely to increase.

For this reason ADSSC appointed KN Intl. to have an overview of all private and public infrastructure projects in the Western Region related to sewerage works. Part of the scope is to overview the Al Yabana development. The project Consultant responsible for the works is M/s Dorsch. Al Yabana is an existing settlement comprising 2 separate communities. The lower community housing has 40 existing villas (no other facilities) and the upper community housing has 30 existing villas.

The 20 no.’s new villas will be added to this upper community. It will have a total population of 420 capita. The scope for sewerage works includes the following:
