The project comprised the construction of a major storage reservoir in Wadi Mallaha which lies adjacent to the Jordan River, 6km north of Karameh town. The purpose of this reservoir is to store surplus winter flows in the King Abdullah Canal and side wadis to allow implementation of irrigation at the southern end of the Valley.
The reservoir lies below the level of the canal, and is connected to it by means of a twin pipeline system. The latter is used both to fill the reservoir with water and to pump water from the reservoir to the Canal during spring / summer, as the need arises.
This earth fill dam has a 55MCM storage volume. It is 45m high and 2050m long, with a 10m wide crest. Draw off works include a 5.2m diameter tunnel 462m long, a 38m high intake tower, a 385m long spillway chute, 3-4m width, 6.3km of diversion canals, and 500m of diversion bunds, a pump station with 4 pumps each of 1.33 l/s capacity, and a 1.2m diameter twin conveyance pipeline of 3.6km length.
Consolidated Consultants was given an Award of Excellence by the late King Hussein of Jordan as recognition of the high quality services provided through this project.
