Water tank sterilization in Kudai Makkah
Kudai is an old commercial zone on the lower slopes of Jabal Khandamah, home to major hotels and tower blocks, bus and car parks. The tanks here serve large seasonal flows of pilgrims, tourists, workers and travellers. Water travels through long pipelines from a distant desalination plant and sits in open tanks on the roofs of older hotels.

Why the job is different in Kudai
Hotels and public facilities depend on large and multiple water tanks, and open-roof tanks face dust from Jabal Khandamah and dry heat exposure year-round. The method is set out in full on our Water tank sterilization service.
High open hotel tanks on rooftops
Hotel towers on Ajyad Street hold water tanks on exposed roofs facing sun, air and dust. Older tanks accumulate mineral deposits from the desalination plant and algae grows in static water.
Long pipelines from the distant desalination plant
Water arrives from a remote desalination station through very long pipe networks. Old pipes collect internal sediment and rust, and water reaches the tanks warm, carrying sand and dust particles.
Sharp seasonal demand from pilgrims and tourists
Kudai lies on pilgrim and tourist routes, and hotels receive large seasonal occupancies. Tanks drain and refill quickly, resuspending floor sediment and carrying bacteria and debris.
The character of Kudai
Commercial area: offices, showrooms and small stores
An old commercial and hotel zone means tanks are very aged and sit on historic hotel rooftops. Water arrives from a distant desalination plant via long pipelines that may be contaminated. Sterilization here requires thorough inspection of both pipelines and tanks together.
What we read inside the tank before anything starts
A commercial and tourism zone south-east of the Grand Mosque along Ajyad Street, containing hotels, tower blocks, vehicle parks and old and new retail premises, on the slope of Jabal Khandamah and close to the water desalination plant.
Sediment on the floor
Dust and sand from Jabal Khandamah enter open tanks and settle on the floor alongside mineral deposits from desalinated water.
The slime film on the wall
White scale and salt residue from desalination deposits on tank walls and floors, forming thick sludge film that requires high-pressure washing to remove.
Light and heat
Long pipelines from the desalination plant carry dust, sand and bacteria, requiring inspection and high-pressure flushing before each tank sterilization.
The lining and any cracking
Humidity inside the tank is low but heat is intense, causing evaporation and sediment concentration. Algae does not grow easily but salt-loving bacteria thrive.
The lid and the openings
The rooftop tank needs regular inspection for external cracks and leaks. A broken or open lid allows Jabal Khandamah dust to enter freely.
What shows up at the tap
Sharp seasonal demand means tanks drain and refill at high speed, sediment mobilizes and water turns cloudy. This signals urgent need for 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 Misfalah Sub-Municipality
Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.
Questions about this district
Why do tanks in Kudai need frequent sterilization?
Tanks are open-roof on hotel rooftops and face dust from Jabal Khandamah. Water arrives from a distant desalination plant via long pipelines that may carry contamination.
Do dust and sand from Jabal Khandamah enter the tank?
Yes. Dry air and wind carry Khandamah dust particles. Open tanks offer no shelter and dust settles on the floor alongside other sediment.
How does sharp seasonal demand affect water quality?
When tanks fill and drain rapidly, floor sediment is resuspended and mixes into the water. This raises bacterial counts and particulate load in consumed water.
Is a single sterilization enough for a full year?
No. Hotel tanks in Kudai need sterilization at least every three months. Constant dust exposure and seasonal swings require repeated maintenance.
How do we handle the long contaminated desalination pipes?
We flush pipes with high-pressure water then sterilize before refilling the tank. This removes sediment and internal rust from the pipeline.
Are plastic tanks better than concrete ones in Kudai?
Plastic tanks resist dust better and are easier to clean. But old concrete tanks remain on hotel rooftops and need deeper sterilization treatment.
How much does water tank sterilization in Kudai 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 Kudai.
