Project Description

Review, assess and update the base date and the design parameters used in "Updated Technical, Economic and Financial Feasibility Study for Wastewater Collection and Treatment Systems in Greater Irbid Area-Stage II" by Deutsche Abwasser Reingigugns-Geselschaft DAR in 1998, and "Reuse System Project for the Yarmouk River and Jordan River" by TYIPSA Consulting Engineers & Architects in 1998.  The updated data was used to prepare the Engineering Review Report, which included the review and examination of the wastewater treatment process alternatives and the different site locations for the treatment plant and pumping stations, as well as preparation the preliminary engineering design for the Project's Wastewater Collection and Treatment System. 

Updating the capital and operation and maintenance cost estimate as also carried out. Design, detailed design was prepared for sewer networks and house connection for 11 communities in Irbid, in addition to the design of the trunk sewers, the treatment plant and the effluent reuse conveyor to North Jordan Valley.  The project serves about 130,000 inhabitants in the eastern area of the project which is expected to increase to 240,000 in year 2025 and 22,000 in the eastern area. 

The eastern area will be drained toward the new WWTP, while the western area to the existing Wadi Arab WWTP.The length of the sewer collection networks is 510 km with diameters between 200 & 400 mm.  The length of the trunk sewer is about 54 km for both areas with diameters varying between 300 & 900 mm.The capacity of the treatment plant is 15,000 m3/day for the year 2015 and 22,000 m3/d for year 2025. Extended aeration was adopted in this treatment plant and all required lifting station and pumping stations were designed.

The project included an environmental scoping session and preparation of an EIA study for the project.The project activities included preparation of tender documents, prequalification of Contractors and evaluation of submitted offers by Contractors.The design was developed by CC in AutoCAD and GIS format.  The GIS maps covered all the networks, house connection and trunk mains.  All related information was incorporated as attribute files to the developed GIS maps. The project was divided into 13 contract packages. The work included also the supervision of construction of all project components
