Water tank sterilization in Al Aziziyah Makkah
Al Aziziyah is a dense commercial district on the pilgrims' route to Mina, where hotel towers, temporary lodgings and markets swell during Hajj and Umrah seasons. Water tanks here face massive and cyclical demand pressure, and the water carries sediment and algae from desert soil and dust that seeps through old foundations. Sterilization is not optional but a health necessity to protect pilgrims and tourists from bacterial and viral contamination.
-
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 Aziziyah
Hotels and pilgrim facilities here serve widely fluctuating guest numbers, from hundreds in off-season to thousands during peak seasons, meaning water tanks face extreme swings in consumption. The method is set out in full on how we approach Water tank sterilization.
Large hotel tanks foul quickly from seasonal load surges
A single hotel may contain one or more tanks holding hundreds of thousands of litres. During Hajj or Umrah, these tanks drain and refill several times daily, pulling sediment and debris from the network and settling it on the floor.
Desert soil and dust seep into tanks through foundation cracks
Buildings here, old and new, sit on desert terrain, and underground foundations leak moisture and fine dust particles. Pipelines draw these particles and microbes from the soil, and they settle in the tank bottom.
Algae and bacteria grow rapidly in heat and dark tanks
High temperatures and darkness in tanks create ideal conditions for algal and bacterial bloom. Constant water movement stirs sediment and accelerates microbial growth.
Landmarks of Al Aziziyah
Access to facilities in Al Aziziyah runs via King Abdulaziz Road and Al Masjid Al Haram Road, with the old Umm Al Qura University campus and Mahbas Al Jinn bus station marking the district boundaries and defining the service zone.

What we read inside the tank before anything starts
A commercial quarter six kilometres from the Holy Haram on the Mina route, containing large hotels, pilgrim housing and retail markets with bus terminals. It is bounded by King Abdulaziz Road and Al Masjid Al Haram Road on one side, and the old Umm Al Qura University campus on the other.
Sediment on the floor
Dense sediment accumulates on the floor from desert soil and fine dust particles seeping through pipelines and foundation cracks below ground.
The slime film on the wall
Biofilm and algae coat tank walls and floor from stagnant water and high heat.
Light and heat
The pipeline network from tank to remote points (upper guest rooms) may trap sediment and bacteria in cool zones.
The lining and any cracking
Stagnant water in the tank caused by uneven consumption creates ideal conditions for microbe survival.
The lid and the openings
The tank itself may contain small voids or cracks where bacteria and algae hide and persist.
What shows up at the tap
Contamination signs appear when water colour or smell changes, when sediment appears in taps, or when turbidity and pH readings shift outside normal ranges.
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 Aziziyah (Makkah) Sub-Municipality
Al Aziziyah sub municipality runs from the Bin Dawood markets to the Al Hada road and carries pilgrim traffic to Mina. Hotel towers and furnished apartment blocks fill and empty with the Hajj and Ramadan seasons, and the kitchens, restaurants and markets along Al Masjid Al Haram Road and King Abdulaziz Road leave food waste at every peak. Southwards the fabric loosens into villas and planned streets in An Naseem and Al Awali, then Al Abidiyah's campus and the old farms of Al Husayniyah, where Wadi Uranah holds water after rain and farm enclosures shelter rodents and reptiles.
Questions about this district
Why does the water colour change in my hotel during Hajj?
Desert soil and dust seep into the tank through pipelines and cracks. High water pressure draws contamination from the network. Regular sterilization prevents this sediment buildup.
How often should a tank be sterilized during peak season?
It depends on consumption and hydraulic balance. Large hotels may need monthly sterilization or more, especially if water quality shifts.
Is tank sterilization enough to protect guests from waterborne illness?
Full sterilization kills most bacteria and viruses. But pipework and fixtures must also be checked to prevent recontamination.
Does cold water reduce algae growth in tanks?
Yes, lower temperatures slow algal and microbial growth. But in Makkah, even cooled water may grow algae if the tank lacks proper sealing and sterilization.
What is the difference between tank sterilization and line sterilization?
Tank sterilization targets the floor, walls and accumulated sediment. Line sterilization ensures water stays clean all the way from tank to the furthest tap.
Do plastic tanks need more sterilization than metal ones?
Cheap plastic tanks may leak more and algae cling to their walls. Good metal ones are stronger, but both need the same routine sterilization.
How much does water tank sterilization in Al Aziziyah 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 Aziziyah.
