Water tank sterilization in Al Qararah Wa Al Naqa Makkah
Al Qararah Wa Al Naqa is an old quarter east of the Grand Mosque, and parts of it are now under reconstruction as part of the Rua Al Haram scheme. Tanks here are a mix of old and new: some in aging buildings with weak foundations, others in new buildings under construction. Water may pass through old fragile pipes before reaching new tanks, or vice versa. Sterilization must account for this blend and constant change.

Why the job is different in Al Qararah Wa Al Naqa
Buildings in Al Naqa and Al Qararah are very old with weak foundations, but the southern section nearest the mosque is under reconstruction and modernization. The method is set out in full on what Water tank sterilization involves.
Old tanks in buildings with weak foundations
Old buildings in Al Naqa sit on weak stone bases with deep cracks. Their tanks may be very old and contaminated from years of use. Thick mineral sediment covers the base and pipes.
Mixed piping: old and new connected together
Pipes in the zone are a mix of old rusted iron and modern plastic lines. Joints between them may leak or create contamination crossovers.
Fluctuating water pressure from elevation and ongoing construction
The area slopes gradually towards Al Mualla and active construction causes water supply interruptions and pressure swings. Air and dirt enter tanks repeatedly.
Al Qararah Wa Al Naqa on the map
Al Qararah Wa Al Naqa sits about 0.5 km from Shaib Amir Wa Shaib Ali and about 0.5 km from Harat Al Bab Wa Al Shamiyah.
Open in Google MapsWhat we read inside the tank before anything starts
An old quarter east of the Grand Mosque, once known as Qararat Al Madha and neighbouring Al Naqa lanes. The Masjid Al Rayah and Masjid Al Jinn stand at its edge where Al Masjid Al Haram Road climbs towards Al Mualla. Parts closest to the mosque now fall within Rua Al Haram redevelopment.
Sediment on the floor
Thick mineral sediment from years of hard and contaminated water coats old tank floors and corners.
The slime film on the wall
Old thick biofilms exist in tanks not cleaned regularly, appearing brown or black.
Light and heat
Mixed pipe networks of old rusted iron and plastic may contain ancient rust and salt residue from metal sections.
The lining and any cracking
High moisture from soil, nearby cracks and construction accelerates biological growth.
The lid and the openings
Tanks may sit in deep corners of old buildings or on unprotected roofs exposed to dust and construction debris.
What shows up at the tap
Noticeable colour change, foul odour and cloudy water signal deep contamination requiring advanced cleaning and strong 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.
The character of Al Qararah Wa Al Naqa
New development: ongoing construction and vacant plots between the homes
The zone mixing old and new means a blend of tank and pipe types. Old buildings with weak foundations need deeper leak inspection, and new buildings need initial cleaning. Sterilization must handle both types and inspect joints and mains carefully.
Questions about this district
Why do old tanks in Al Qararah Wa Al Naqa need deeper cleaning?
Mineral deposits and biofilms have accumulated over many years. Very high-pressure cleaning combined with longer soaking periods is required.
Does mixed old and new piping cause contamination problems?
Yes. Joints may leak and allow contaminated water to enter. Sterilization must inspect these joints carefully.
Do weak foundations affect the tank and water?
Yes. Cracks may allow contaminated seepage from soil. Tanks near weak foundations need extra protection.
Does constant pressure change affect sterilization effectiveness?
Yes. Pressure fluctuations allow contaminants to enter between sterilization cycles. Sterilization may need to recur more often than in other areas.
Why might new buildings in this zone need a different sterilization approach?
New buildings may have new tanks and modern pipes, but may connect to old pipes. This means both sections need cleaning.
Will ongoing construction in the zone cause water fluctuations for a long time?
Yes. The project may last years. Pressure swings may recur intermittently, so continuous monitoring is important.
How much does water tank sterilization in Al Qararah Wa Al Naqa 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 Qararah Wa Al Naqa.
