Water tank sterilization in Al Bayban Makkah
Al Bayban is an ancient quarter on a hill north of the Grand Mosque, with stone palaces and buildings erected over a century ago. The tanks here are very old and laden with thick sediment and biofilm. Sterilization requires deep cleaning and high-pressure washing to remove years of accumulated deposits.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-

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.

Why the job is different in Al Bayban
Buildings here are very old, most constructed in the early twentieth century from stone, earth and lime, with concrete tanks mounted on roofs that are decades old and caked with deposits. The method is set out in full on Water tank sterilization in detail.
Tanks mounted on stone roofscapes
Tanks in Al Bayban sit directly atop old stone buildings. Water sits in them for long periods and extreme heat accelerates biofilm and rust formation.
Heavy sediment and mineral load
Water from old wells and pipelines carries mineral deposits and high calcium content. Sediment settles thick at the tank base and hardens into a stubborn layer.
Biofilm grows fast in extreme heat
High temperatures on Al Bayban's exposed roofscape speed bacterial and algal growth on tank walls. Poor ventilation and ancient surfaces create ideal conditions for contamination.
Landmarks of Al Bayban
Access to Al Bayban runs via Madinah Road from the south, with Qasr Kuwair, the historic five-storey palace crowning the hill, as the primary landmark and navigation anchor.

What we read inside the tank before anything starts
A historic quarter on a hill north of the Sanctuary between Al Diyafah and Al Hajun off the Madinah road, home to palaces, old houses and period mosques.
Sediment on the floor
Water from old wells carries heavy clay and mineral deposits that settle in the tank base.
The slime film on the wall
Thick biofilm adheres to tank walls due to high heat, moisture and light exposure over time.
Light and heat
Old corroded pipelines on roofs shed rust particles into the water supply.
The lining and any cracking
Extreme temperatures on Al Bayban's high roofs speed biofilm and algal growth even in newer tanks.
The lid and the openings
Very large tanks in the palaces create deep zones where sediment does not settle easily and stays suspended.
What shows up at the tap
Slow flow or stagnant water for long periods speeds contamination and film, especially on exposed surfaces.
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 Utaybiyah Sub-Municipality
Al Utaybiyah sub municipality covers the old districts north of the Grand Mosque: the hillside quarters of Al Hajun, Al Utaybiyah and Al Bayban, Al Zahir and Al Shuhada at the northern entrance, and the newer Al Zahra, Al Diyafah and An Nuzhah westward. Its building stock is among the oldest in Makkah, stone houses on the hills, packed apartment blocks and sewers decades old, threaded with crowded markets like the Utaybiyah souq and furnished flats that fill in the pilgrim seasons. Wadi Al Zahir and Wadi Al Tanim carry storm water through it, and industrial workshops line Hajj Street.
Questions about this district
Why do tanks in Al Bayban foul faster than in other quarters?
Water from old pipelines carries more sediment and extreme roof heat speeds biofilm growth. Old tanks themselves do not insulate well against temperature swings.
Is one sterilization per year enough for an old tank?
Usually not. Old tanks foul quickly and deposits return. Sterilization every six months is safer, or before the summer heat surge begins.
Do thick deposits require special tools to remove?
Yes. High pressure and steel brush are needed to strip hard sediment and calcified biofilm.
Does mineral-rich water speed the fouling?
Very much so. Minerals and salts in the supply accelerate biofilm formation and rust on walls.
Do old palaces need different treatment?
Yes. Palaces have very large tanks and very high roofs. Access is harder and sterilization needs special equipment and more hands.
Does sterilization include flushing the lines downstream from the tank?
Yes. After tank sterilization we flush lines from the furthest tap because sediment also settles in pipes and clogs outlets.
How much does water tank sterilization in Al Bayban 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 Bayban.
