ZAKHO DREAM CITY PROJECT
Sector: Settlement
Location: Zakho /Iraq
Raw water source: Khabur
River Water
Capacity: 12.000 m3/day
A surface water treatment system is designed to provide Dream City residence project in Zakho city with drinking and potable water using nearby Khabur River as raw water source.
In the project, 2 submersible pumps with 325 m3/hour capacity each, are feeding river water which shows seasonal changes to the surface water treatment system. Sedimentation units designed in parallel uses coagulation, flocculation and lamella and have capacity of 265 m3/hour each.
Coagulation is designed along with polyelectroltic preparation and dosage units to get maximum efficiency from softening, sedimentation and coagulation. Water from sedimentation unit is transferred to the intermediate transfer tank. To provide low velocity filtration, horizontal filters 12 m in lenght and 2.85 m in diameter are designed. The system is designed as two parallel lines, after sand filters remove suspended solids, turbidity and deposition, active carbon filters remove taste, odor and organic contamination. Cartridge filters with 10 micron sensitivity will treat water before storage in clean water tanks. River water and treated water will be disinfected using gas chlorine. The system will work in fully automatic regime and with the help of three pumps 250 m3/hour capacity each water will be distrubuted for demands of residence at 145 mss pressure.
The project includes below mentioned components:
- Water intake pump station: 2 x 325 m3/hour
- Clean water pump station: 3 x 250 m3/hour @ 145 mss
- Supply pipe: DN400 2 400 m steel pipe
- Service route: 2600 m stabilized route
- Total construction area 1350 m2
- Steel-construction filtration room where 2 x 250 m3/hour treatment system is installed
- 400 m2 supporting area
- 2x500 kw transformer and 500 kw generator room
- 750 tonnes and 500 tonnes reinforced concrete water storages
- Static, Mechanical, Architechtural and Electrical projects of the whole facility
- Administrative and Supporting Buildings
- Turn key delivery including construction, mechanical and electrical installation material and workmanship
- Delivery of clean water to utilization points - 2,5 km DN 400
The project which includes 42 m steel bridge for water transfer to the system, 500 kW transformer and generator building, 135 m2 steel-construction treatment building and 400 m2 reinforced-concrete supporting facilities is under construction and planned to be finished by the end of 2015.
