Water tank sterilization in Al Mursalat Makkah
Al Mursalat is a district of residential and Hajj hotel buildings on the Mina side, south of Al Aziziyah and crossed by King Khalid Road. Hotels and apartment blocks here serve millions of pilgrims each year, and tanks endure very high consumption pressure. Water flows through complex pipe networks and large tanks requiring frequent sterilization to ensure pilgrim and resident safety.
-
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 Mursalat
The district hosts large hotels and densely occupied apartments, with tanks bearing very high daily water consumption throughout the year, especially during the Hajj season. The method is set out in full on the full Water tank sterilization page.
Hajj hotels with large tanks and massive daily consumption
Large hotels here receive thousands of pilgrims seasonally, and tanks serve bathrooms, kitchens and laundry without pause. Massive consumption causes rapid sediment formation and warm water from bathrooms accelerates bacterial growth.
Complex pipes between tightly packed hotels and residential buildings
Hotels and apartments are very close together and pipes extend across shared roofs and walls. Old pipes corrode and leak, and high pressure causes rapid damage and cross-contamination between adjacent tanks.
Hajj season increases contamination through crowding and peak demand
Outside Hajj, consumption is routine. During Hajj, consumption doubles and tanks fill and drain rapidly, resuspending sediment and mixing old and fresh water. This accelerates biofilm formation.
Landmarks of Al Mursalat
Access to Al Mursalat runs via King Khalid Road from the north and the Fourth Ring Road from the east. The Saudi National Hospital, the East Aziziyah health centre and Souq Al Aziziyah mark the district boundaries and ease access to buildings and hotels.

What we read inside the tank before anything starts
A district of residential and Hajj hotel buildings south of Al Aziziyah and very close to the Mina side, crossed by King Khalid Road and the Fourth Ring Road. Apartment and hotel buildings stand over banks, restaurants and shops along Al Masjid Al Haram Road.
Sediment on the floor
Sediment from massive consumption accumulates rapidly at the base of large tanks, containing rust from pipes and metal debris from high pressure stress.
The slime film on the wall
Biofilm forms quickly on tank walls due to warm water from bathrooms and continuous consumption, with bacteria feeding on soap and shampoo residue.
Light and heat
Complex pipes between adjacent hotels and buildings show corrosion and leaks from high pressure and constant movement stress.
The lining and any cracking
Moisture and tank temperature remain high due to continuous consumption and warm water from hotel bathrooms running throughout the day.
The lid and the openings
Large tanks contain deep sediment layers that can reach tens of centimetres in older tanks.
What shows up at the tap
The Hajj season raises contamination rates through massive consumption and tanks being filled from multiple sources, mixing old and fresh water and accelerating bacterial growth.
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
Is once-yearly sterilization enough for a Hajj hotel?
It may not be. Hotels consume very high water volumes and tanks need sterilization every 3-6 months, especially before and after the Hajj season.
Why does water discolour faster in Al Mursalat than other quarters?
Consumption is very high, tanks are large and pipes are complex. High pressure continuously resuspends sediment from the base.
Does treating one hotel tank stop cross-contamination from neighbouring tanks?
No. If pipes are shared or very close, contaminated water from another hotel may enter yours. Each tank must be treated separately and pipe connections checked.
What is the difference between sterilizing before and after Hajj?
Pre-Hajj sterilization ensures clean water for arriving pilgrims. Post-Hajj sterilization removes accumulation from massive consumption and restores the tank to normal operation.
Are large tanks easier or harder to sterilize than small ones?
Large tanks hold more sediment and need longer treatment and larger disinfectant doses. Washing pressure must be higher and ventilation is critical.
Is hotel water safe to drink immediately after sterilization?
Yes, but pipes must be flushed with clean water after sterilization to remove disinfectant traces. Hotels usually flush from the furthest tap to the first-use point.
How much does water tank sterilization in Al Mursalat 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 Mursalat.
