Water tank sterilization in Al Thaalibah Jeddah
Al Thaalibah is an old unplanned quarter in south west Jeddah with dense low-rise apartment blocks and patchy services. Water tanks here have accumulated sediment and silt for years because regular maintenance was never established. Sterilization requires complete drainage, lifting heavy floor deposits and thorough wall washing before disinfectant is applied.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Thaalibah
Most buildings were constructed thirty years ago or more, and old concrete tanks contain heavy sediment and coloured silt deposits. The method is set out in full on how we approach Water tank sterilization.
Old concrete tanks and heavy sediment buildup
Tanks here are simple cast concrete with decades of neglect leaving thick sediment layers on the floor up to 30 centimetres deep. The aged concrete cracks easily and leaks.
Aged supply lines and filthy pipes
Pipes from tank to apartments are very old and have never been flushed internally. Algae and deposits clog lines and reduce water pressure throughout the building.
Interrupted services and repeated tank failure
Regular water cuts leave tanks exposed and vulnerable to external contamination. Residents fill tanks from mixed sources and few buildings have filters installed.
The character of Al Thaalibah
Apartment district: residential blocks, repeated floors and shared entrances
An old unplanned residential quarter means tanks were built to varied standards with sometimes inadequate sealing. Treatment here requires longer sediment removal time and may demand minor repairs to cracks and leaks.
What we read inside the tank before anything starts
An old unplanned residential quarter in south west Jeddah bounded by Al Hindawiyah to the north, Al Quraiyat to the east, Petromin to the south and the Islamic Port to the west, edged by King Khalid Road and Al Falah Road.
Sediment on the floor
Heavy sediment and silt accumulate on the floor from years of neglect and contaminated water drawn from mixed external sources.
The slime film on the wall
Algae and bacterial biofilm grow on concrete tank walls because moisture and light seep through cracks.
Light and heat
Supply pipes from tank to apartments carry internal deposits and low-flow lines are clogged with salt and silt layers.
The lining and any cracking
Moisture is continuous from tank leaks and old pipe seepage, sustaining ideal conditions for fouling.
The lid and the openings
Bacterial and algal colonies concentrate on the tank floor, corners and dead legs where water sits stagnant.
What shows up at the tap
Visual inspection or smell gives surface assurance, but internal blind pipes may harbour deep contamination.
How we work
-
1
Inspect and record the condition
We open the hatch and work through what the tank is made of and how big it is, how deep the sediment lies, the state of the lining, whether the lid and the overflow seal, and whether there is a crack that has to be repaired before any sterilizing.
-
2
Drain and lift the sediment out
The water goes out, then the silt and sand are lifted off the floor by suction rather than pushed toward the outlet, because pushing them sends them into the house pipework and the heater.
-
3
High pressure wash
Walls, floor, corners and the area around the outlet, until the slime film is completely gone. This is the step that makes the sterilizing after it mean anything.
-
4
Sterilize, rinse, then return to service
The sterilizing agent goes onto the walls, the floor and the underside of the lid and is left for its contact time, then we rinse, refill and run the furthest tap until the whole line is clear.
What water tank sterilization includes
-
A recorded inspection
Material, capacity, sediment depth, the state of the lining, the lid and the overflow, all before any work begins.
-
Draining and sediment removal
The water out, and the silt and sand lifted off the floor instead of being pushed into the outlet and the house pipework.
-
High pressure washing
Walls, corners and around the outlet, until the biofilm that no disinfectant penetrates has gone.
-
Sterilizing the internal surfaces
A sterilizing agent meant for drinking water tanks, applied to the walls, the floor and the underside of the lid, and left for its contact time.
-
Line flush and aftercare
Rinse, refill and a flush from the furthest tap, when the water is usable again, and what to change in the filter afterwards.
-
The next cycle
We agree the right interval for your tank from how it is filled, how much sun it takes and the condition of the lid.
What is different about Al Jamiah Sub-Municipality
Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.
Questions about this district
Why is sediment buildup heavier in Al Thaalibah than in new quarters?
Tanks have not been cleaned since installation. Water supply here originates from mixed sources and the salt and silt load is far higher.
Is one tank cleaning enough or does this area need repeated maintenance?
One thorough cleaning improves water quality significantly, but annual maintenance is necessary here because old pipes constantly shed internal deposits.
What drives higher sterilization costs in Al Thaalibah?
The volume of sediment extends cleaning time. Weak concrete may also need minor repair work.
Does tank sterilization remove bad taste and odour?
Full cleaning and sterilization removes most baseline odour and taste, but if the supply pipes themselves are fouled, odour may gradually return.
Should an old tank receive a protective internal coating after sterilization?
Very old pipes here might benefit from a coating. But if original lines remain, coating alone is insufficient.
How often should we inspect the tank after sterilization?
First inspection one week after treatment to confirm sediment does not return, then annual routine checks.
How much does water tank sterilization in Al Thaalibah cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Thaalibah.
