Water tank sterilization in Wali Al Ahd Makkah
Wali Al Ahd is a new development district south of Al Shawqiyah within the Haram boundary, surrounded by three-storey apartment buildings and residential plots still under construction. Tanks here are newly built with copper or plastic piping of good quality, but new construction sites leave building dust and light metals in the tank. Sterilization focuses on removing construction residue before handover.

Why the job is different in Wali Al Ahd
New residential projects here are still incomplete and tanks are new but contain cement dust and light metal residue from construction. The method is set out in full on Water tank sterilization in detail.
New tanks with construction dust
New residential projects are still under active building and cement and steel dust spreads through the air. New tanks become contaminated with this dust and light metals before handover.
Modern copper and plastic piping
Pipes in new projects are copper or high-grade plastic. There are no rust problems, but construction dirt needs rapid removal before water use.
Handover and rapid commissioning
New projects need fast sterilization before residents move in. Sterilization here happens before actual use, not routine maintenance.

What we read inside the tank before anything starts
A new development district south of Al Shawqiyah within the Haram boundary, bounded by Al Malik Fahd to the west and Al Ukayshiyah to the east, with three-storey apartment blocks and residential plots under active construction.
Sediment on the floor
Light sediment from cement dust and thin metals settles in the new tank and needs strong flushing before sterilization.
The slime film on the wall
The fine white layer on new tank walls is construction dust and lime, washing away easily under high pressure.
Light and heat
New copper or plastic pipe runs are very clean and need initial flushing to remove factory and installation dirt.
The lining and any cracking
Humidity in the new tank may be high from site moisture and construction, but no major microbial activity before first use.
The lid and the openings
The new tank is free of deep sediment because it has not been used, but dust and rubble from the construction site enters when first filled.
What shows up at the tap
First water may be cloudy or have faint colour from light metals, requiring full flushing before sterilization.
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 Shawqiyah Sub-Municipality
Al Shawqiyah sub municipality runs south from the Third Ring Road to the city's edge on the Al Layth road and the Jeddah expressway. Planned districts such as Al Shawqiyah, Al Malik Fahd and Bathaa Quraish have wide streets, villas and apartment blocks, while schemes in Wali Al Ahd are being built out and informal housing in Al Ukayshiyah and Al Zuhur is being cleared. The vegetable market and livestock auction at Souq Al Halaqa, open construction sites, the rocky slopes of Jabal Thawr and sewers still being laid through the southern fringe offer exposed food, shelter and moisture.
Questions about this district
Do new tanks need sterilization before resident handover?
Yes, absolutely. New tanks contain construction dust, metals and machine oils. Sterilization is essential before first use.
Why does building dust enter a new tank?
Tanks are filled before construction ends. Dust, wind and construction rubble enter through vents or during initial filling.
Is sterilization enough or does it need repeated flushing?
Sterilization is sufficient after good flushing. All taps must be opened and water run until it runs clear, then sterilant applied.
Is chemical sterilant safe for drinking water in residential projects?
Yes, we use approved and safe sterilants. After sterilization and thorough flushing, water is safe to drink.
How long does sterilization take in a new tank?
Sterilization takes hours. It includes flushing, cleaning, sterilant application and final flushing, taking two to three hours.
Do new tanks need routine sterilization after handover?
If first sterilization is done well and pipes are copper or plastic, routine sterilization is every year or two.
How much does water tank sterilization in Wali Al Ahd 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 Wali Al Ahd.
