Sludge Treatment

Abstract

The ISTP2 project is a build, own operate and transfer (BOOT) project, which consists in the design, construction, financing and operation of two wastewater treatment plants in the Emirate of Abu Dhabi. These plants, which were commissioned in January 2012, serve two main purposes: To treat the growing amount of wastewater produced in Abu Dhabi and Al Ain following the current demographic growth. To recycle treated water for irrigation of the green areas (farms, parks, green spaces, etc) of Abu Dhabi and Al Ain. The Al Wathba 2 Plant treats a significant part of the wastewater coming from the city of Abu Dhabi. This Plant has a treatment capacity of 300,000 m3 per day and is designed for a Population Equivalent of over 1,500,000 units. The Allahamah Plant treats a significant part of wastewater coming from the city of Al Ain. This Plant has a treatment capacity of 130,000 m3 per day and is designed for a Population Equivalent of 650,000 units. The owner of these two plants is Al Wathba Veolia Besix Waste Water PJSC, a Special Purpose Company which was incorporated in 2008 for this specific project. It is a joint-venture between the government of Abu Dhabi, represented by ADWEA, and two private companies; Veolia and Besix.
