Tabaqat Fahal (Pella) Water Supply

Client: Water Authority of Jordan.

Project Duration: 1995 – 1998.

The project is located at Northern Jordan Valley. It starts from Tabaqat Fahel Springs near Mashare town to the existing Wadi Arab Water Treatment Plant along the main road.

The project Objective is to collect water from Tabaqat Fahel springs by hydraulic structures and transport the water to a ground storage tank 2000m3 capacity by gravity line 600mm diameter and 18km long then pumping the water through four pumping stations located in North Shuna to existing reservoir in Wadi Arab Water Treatment Station by a pressure line 600mm diameter 8km long.

After that the water will be pumped by three pumping stations to existing reservoir in Zabda – Irbid.

The project consisted of the following:

Civil Works

-    2000m3 capacity ground reservoir at Tabaqat Fahel intake pumping station.

-    4 pumping stations of built up area 578m2 each in 4 different sites.

-    Reinforced concrete storage tank, collection manhole, grit removal and intake structure.

-    Operation room with an area of about 30m2.

-    4 reinforced concrete bridges.

Mechanical Works

-    Supply, install, test, commission and maintain 12 horizontal split casting multi stage, electrically driven units, 3 pumping units in each pumping station with capacity of 660m3/hr at a total dynamic head of 250m for each pump.

-    Supply, installation, testing, commissioning and maintenance of a complete electrical over-head traveling gantry cranes (one for each proposed pumping station) 10 tonnes lifting capacity.

Electrical Works

Supply, install, operate, test and maintain the following electrical items for each pumping station:

-    Complete 5 motor feeders (6.6KV starts switch gears).

-    Complete service power transformer rating 250KVA.

-    Medium tension main distribution panel (MT.MDP) 6.6KV. 3 phase.

-    Complete vacuum circuit breakers (V.C.B. 6.6KV) for the main power supply (TF33/6.6KV).

-    Complete V.C.B. switch gears 6.6KV, 05HZ, 3 phase.

-    Complete low tension main distribution panel (LT.MDP) 3 phase, 400V., 50HZ.

-    Outdoor-Indoor electrical installation and earthing system.

Pipe Works

Supply and install the following lengths of pipes with all connections, all required fittings, nd all kinds of valves:

-    970 M.R. Black steel pipes 800mm diameter.

-    26350 M.R. Ductile iron pipes 600mm diameter.

-    5125 M.R. Black steel pipes 600mm diameter.

-    Valve chambers, surface box, reinforced encasement, thrust block, and all other works related to pipeline works.

CEC’s duties included the review of design and construction supervision services.

The project construction cost is about 16.5 million USD.

Financed by the French Government.
