Objectives:

The main objective of the Disi-Mudawwara to Amman Water Conveyance System project is to supply additional sustainable potable water to the Greater Amman Area to satisfy water demands and nullify deficits.

Project Components:

Although its capacity might eventually be increased, the project will initially produce and transport to Amman on average 100 MCM of high quality water per year, with the minimum flow being 80 MCM/yr. during winter months and the maximum flow being 120 MCM/yr. during summer months.  Facilities to build include:

1. Well fields consisting of new boreholes (65 wells)

2. Well fields collectors, 250 mm-1600 mm diameter steel and/or DI pipes of 100 km length.

One collector reservoir in the Disi-Mudawara area (12000 m3) with the necessary piping systems to collect water from the above noted well  fields.  This reservoir will become the facility from which water is conveyed to a terminal reservoir in Amman.

Main pumping station and associated balancing tanks.

Regulating tank (16600 m3) and flow control stations Chlorinating units at the main pumping station and other sites, as required Conveyance pipeline to Amman (325 km), 1800mm-dia steel pipes 2000mm diameter steel pipes and 1000mm diameter Steel Pipe (part new and part existing).

Operation and maintenance facilities, including roads, staff residence, offices, communication, and telemetry services, electrical transmission lines to the Well fields and pumping stations, and stand by power generators at those stations:

1. Cathodic protection of the pipeline

2. Terminal reservoir at Amman

Project Status

A full feasibility study on all technical, economic, financial and environmental aspects of the project was completed in mid-1996.  Additionally, a preliminary design study and tender documents including geotechnical investigation were completed in mid 1997. The consultants Brown and Root North Africa have recently updated the studies and updated the tender documents.

Prequalification has been completed, and the tender documents where delivered to the prequalified consortia. The Technical and financial offers were received and opened on 20th August, 2003 which are under evaluation by MWI.

Implementation:

This project will be implemented on BOT basis, under which a private contractor would build, own and operate and transfer.

Cost estimates:

The estimated base capital costs of the project are US $600 million. 

Timing:

The tentative timetable for the competition of the project is 5 years.

Guarantees:

The World Bank is ready to support the project financially through partial risk guarantee.
