Water tank sterilization in Harat Al Shuruq Jeddah
Harat Al Shuruq holds old popular houses alongside newer low-rise apartment buildings. Tanks here are mixed: some sit on roofs, others below ground, and water travels slowly through long lines across the quarter. Sediment and biofilm accumulate quickly in older tanks and extended piping.
-
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 Harat Al Shuruq
Houses here span old and new types, with tanks ranging from simple traditional units to modern systems serving the newer buildings. The method is set out in full on how we approach Water tank sterilization.
Mixed tanks on roofs and underground
Old houses in the quarter have rooftop tanks exposed to harsh sun and wind. New buildings have underground or internal tanks, but the supply lines from tank to homes run long distances through the quarter.
Long pipes and slow water flow
Distance from the pump station to the furthest house is considerable, and water sits in the pipes for extended periods. This allows biofilm and sediment to form in long supply lines.
Coastal climate and desert dust impact
The quarter is open to desert air and winds carry dust and fine particles. This increases debris accumulation in exposed and unprotected tanks.
Landmarks of Harat Al Shuruq
Access to Harat Al Shuruq runs via the Madinah highway on one side and open ground at the Wadi Thuwal bed on the other, defining the service boundary.

What we read inside the tank before anything starts
A mixed residential quarter in Thuwal combining popular houses with newer low-rise buildings, surrounded by open ground and the bed of Wadi Thuwal on one side and the Madinah highway on the other.
Sediment on the floor
Heavy sediment builds up in tank bases from distant pump stations and carries desert dust.
The slime film on the wall
Biofilm grows on tank walls and in long pipes where water moves slowly and sits for extended periods.
Light and heat
Cracks and leaks in old tanks allow insects and contaminants to enter from outside.
The lining and any cracking
Internal moisture is high in underground and covered tanks, while open tanks face evaporation and airborne contamination.
The lid and the openings
Internal pipework may contain rust and mineral deposits accumulated over years.
What shows up at the tap
Bacteria and algae appear when stagnation or contamination continues, especially in distant lines where water moves slowly.
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 Thuwal Sub-Municipality
Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.
Questions about this district
Does sediment buildup in the tank affect water purity?
Yes. Sediment traps bacteria and biofilm grows beneath it. Deep cleaning lifts all sediment from the base to ensure the water is fully clear.
Why does biofilm grow quickly in Harat Al Shuruq?
Long pipes and slow water movement give bacteria time to accumulate. Open tanks also allow insects and dust entry.
Is cleaning one tank enough if the pipes are contaminated?
Not necessarily. We flush the lines from the furthest tap after sterilization to remove contamination from all piping.
Do underground tanks need more sterilization than rooftop ones?
Underground tanks are shaded but cooler and damper, which may encourage some growth. Both types need regular sterilization.
How often should tanks be sterilized in this quarter?
It depends on incoming water quality, tank age and pipe condition. Older tanks may need every three months or more often.
Does desert dust and wind affect sterilization effectiveness?
Yes. If the tank is open or the lid is weak, dust enters continuously. The tank must be sealed tight after sterilization.
How much does water tank sterilization in Harat Al Shuruq 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 Harat Al Shuruq.
