Location:Abu Al-Khaseeb/ Basrah
Establishing Date:1979
Capacity:600 m3/Hr.
No. of Beneficiaries:45000 people

The following table is an explanation of the list of repair items that the Iraqi engineers provided.

Repair Items Description of Site Equipment And Repairs
1-6 Upgrading the intake (sucking) pumps located over the Shatt Al Labbani at the end of the 100meter causeway. Includes rebuilding the motor and pump #1, intake (sucking) piping, pump mount, valves, and protective housing for pumping facility. A new control panel and starter circuit will be added to remove electrical hazards that now exist at that pumping station.
7-9 Overhaul 3 of the high lift pumps located in the main building. Includes rebuilding their motors, pumps, valves and painting to prevent corrosion. The control panel for these pumps will be repaired by replacing its starters, timers, breakers, connectors and buss bars. This will also reduce the electrical hazards that now exist in the building. Repair on one of these pumps began while Team 1 of IWP was at Labbani.
10-14 Upgrade the two solids contact/sedimentation tanks. New valves will be installed on the raw water and discharge lines. The thick, compacted deposit of alum mud fouling the bottom of the tanks will be removed and disposed of outside the plant site. The piping and valving system that is used the drain off excess alum mud will be completely rebuilt. Overhauling the drive mechanism (motor and gear reduction boxes) for the mud scavenger units on top of each tank; installing new power cables to these units. The drive shaft and rotator connected to these drives will be repaired. A protective shelter will be built over each unit to protect them from the elements. Temporary patches to the sides of the tanks will be replaced with more durable material. A new stairs and bridge to the splitter box (distribution tank) will be constructed.
15 Repair the elevated storage tank holding processed water. Removing mud from bottom of tank; replace defective valves; repair manhole covers (inspection hatches); install new stairs up the tank and add a tank water level control float (rover).
16 Extensive overhaul of the five defunct pressurized water filters. The exterior end of each filter tank will be cut off and then the iron plate dividing the tanks removed. This plate and its broken comb filters will be discarded and a new plate and filters welded back; all rust (inside and out) will be removed and the cleaned iron covered with inert protective coatings. End of each tank will be welded back on. Defective flange valves and pressure gauges will be replaced and new filter media added.
17 Install two compressors (blowers) for backwashing the pressure filters. Each will be capable of producing 250cubic meters/hr (9000 cubic feet/hr) of air at 10 bar (140 lbs/inch). They will be connected to the pressure filters with new piping and valves.
18 Construction of a new ground level alum mixing and injection facility next to the sedimentation tanks. A brick and concrete pad will be built upon which mixing tanks, mixers, and injection pumps will be mounted. A protective shelter will be built over this equipment. Polyethylene tubing will be used to deliver the alum solution to the splitter box (speedy mixing box) located between the tanks. An electrical distribution board holding motor starter circuits will be in the shelter and connected to the main control board.
19-20 Installation of a new 10 kilogram/hr (23 lbs/hr) chlorinator and its injection(booster) pump . The injection pump will be capable of delivering 20 cubic meters/hr (700 gallons/hr) of chlorinating water at 10 bar (140 lbs/inch). New piping and fittings for the chlorinator, booster and chlorine tanks will also be installed.
21 Re-roof main building. Remove old roofing materials and dispose of offsite. Add new asphalt sealing layer, covering with dirt and installing new tiles. Team 1 of IWP started this project while at Labbani.
22 Constructing a ground level concrete channel (pipe gallery) to carry some of the piping that now clutters the site and makes moving around difficult and dangerous.
23,26 Replacing the many broken windows found throughout the site.
24 Install new interior lighting to all the buildings on the site.
25 Install new exterior lighting on the site.
27 Install new doors on all buildings.
28 Provide covers for all existing ground level pipe galleries to reduce walking hazards.
29-30 Install new 2 ton and 5 ton chain hoists in main building for handling heavy equipment.
31 Build new rest room and wash facilities for plant personnel. Team 1 of the IWP started this project while at Labbani. It is just northeast of solids contact/sedimentation tank #2.
