Water tank sterilization in Al Misfalah Makkah
Al Misfalah is an old, low-lying district south of the Grand Mosque, packed with apartment blocks housing Hajj and Umrah visitors. Water tanks here face intense seasonal demand, and the water carries sediment and silt from old pipelines and cracks in foundations. Deep cleaning and regular sterilization are essential because water discolours quickly in tanks.
-
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 Misfalah
Buildings here were constructed decades ago and foundations and piping date back many years. Sediment and silt accumulate in tanks faster than in newer districts. The method is set out in full on the full Water tank sterilization page.
Dense apartment blocks and shared tanks
Flats here are small and crowded, served by one shared tank for dozens of families. Heavy seasonal use causes sediment to build up rapidly at the tank floor.
Old pipelines and rust corrosion
Old copper and iron pipes corrode from the inside, leaving rust particles in the water. These particles settle at the tank base and encourage bacterial growth.
Humidity, seasonal heat and heavy continuous use
During Hajj and Umrah season water flows continuously from dawn to night. High heat, humidity and stagnant water in the tank accelerate the growth of the biofilm layer on walls.
Al Misfalah on the map
Al Misfalah sits about 1.5 km from Al Taqwa and about 1.5 km from Al Rawabi.
Open in Google MapsWhat we read inside the tank before anything starts
An old residential quarter rising from a depression south of the Grand Mosque along Ibrahim Al Khalil Street, with densely packed apartment buildings, retail shops and restaurants. It borders ancient quarters such as Al Kakiyah and Qawz Al Nakasah to the south.
Sediment on the floor
Heavy sediment sits at the tank base from months of rust and silt accumulation and needs powerful mechanical suction.
The slime film on the wall
Tank walls carry a living green biofilm of algae and bacteria, especially in corners and dark areas.
Light and heat
Fine cracks in the tank roof and walls may leak contaminated external water, and inspection focuses on seals.
The lining and any cracking
Humidity inside the tank is very high and stagnant air encourages biological growth, so post-sterilization ventilation is critical.
The lid and the openings
The base outlet is sometimes blocked by silt and sediment, and inspection confirms free flow.
What shows up at the tap
Water remaining in the lines after flushing may carry sterilant residue, and flushing from the furthest tap ensures water safety.
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.
The character of Al Misfalah
Apartment district: residential blocks, repeated floors and shared entrances
Dense apartment blocks mean large shared tanks serving many families. Heavy seasonal use and old pipelines mean sediment builds faster, so sterilization must account for water arriving from an old, contaminated network.
Questions about this district
Why does the tank discolour a month after cleaning?
Old pipelines carry rust and silt particles from the main supply network. The tank collects these from continuous use even if the tank itself is clean.
Is one sterilization enough for the whole year?
In Al Misfalah seasonal use is very heavy. One treatment may not be enough if flow is intense. You may need two per year.
Does sediment at the tank base affect water pressure?
Yes, sediment reduces the tank's effective volume and may block the base outlet. Cleaning restores normal pressure.
Is water safe to drink immediately after sterilization?
Yes, but we flush all lines from the furthest tap. You may want a short delay before using water from the start.
Do apartment blocks need the same process as villas?
No. Apartments share one large tank where sediment builds faster. The process is deeper with emphasis on removing silt from the base rather than in villas.
Is the green layer on tank walls dangerous?
Yes, it is algae and living bacteria growing in moisture and light. Sterilization removes it but it may return if the tank is very sunny or damp.
How much does water tank sterilization in Al Misfalah 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 Misfalah.
