Water tank sterilization in Al Abidiyah Makkah
Al Abidiyah is the modern Umm Al Qura University campus on the Taif road south east of Jeddah. The university operates a single central water distribution system serving colleges, the hospital and student housing. The main tanks are large and now aging, and demand for clean water is very high because thousands of students and staff depend on them daily.

Why the job is different in Al Abidiyah
The main tanks in the campus were built in the eighties and nineties and serve thousands of users under fluctuating pressure throughout the day. The method is set out in full on what Water tank sterilization involves.
Large distributed tanks across the campus
The main water tanks in Al Abidiyah are very large and distributed across multiple sites near each college and the hospital. Each tank feeds a complex network of long pipelines reaching thousands of outlets.
Intensive use and high demand
The university hospital and colleges demand heavy water use throughout the day. Operating theatres, labs, washrooms and bathrooms consume vast amounts under varying pressure.
Long pipelines and distant outlets
The pipeline network extends across the campus from the main tanks to the far edges. Stagnant water at distant and elevated points causes sediment buildup and secondary contamination.
Landmarks of Al Abidiyah
The Al Abidiyah campus sits on the Taif road between Wadi Uranah and Wadi Numan. The main university landmarks including the library, stadium and hospital mark the main tank locations and guide crew distribution across the campus.

What we read inside the tank before anything starts
The Umm Al Qura University campus on the Taif road comprises the colleges of sharia, engineering and medicine, the university hospital, student housing, the King Abdullah Library and the university stadium.
Sediment on the floor
Sediment and silt accumulate in the main tanks due to heavy use, fluctuating pressure and vast water volumes flowing daily.
The slime film on the wall
Biofilm grows in long pipes and distant reaches, especially at low-pressure points throughout the network.
Light and heat
Bacteria and contaminants can enter through small cracks and leaks in the complex distribution system.
The lining and any cracking
Stagnant water at high points and far edges presents secondary contamination risk, particularly critical in the hospital.
The lid and the openings
Distribution lines to operating theatres, labs and washrooms create complex environments for bacterial growth and water degradation.
What shows up at the tap
Fluctuating pressure and intermittent use cause air ingress and debris entry into the network and main tanks.
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
How often must the university campus tanks be cleaned?
University tanks need regular cleaning at least every three months because of high use and continuous demand.
Does intensive use affect stored water quality?
Yes. Fluctuating pressure and heavy use cause air ingress and contamination. Frequent cleaning is essential.
How do we handle long pipelines and large distances?
We flush the tanks and all pipes from start to finish. Distant water needs additional pumping pressure to ensure full reach.
Does the hospital need higher cleaning standards?
Yes. The hospital needs higher health standards. Cleaning and disinfection must be stronger and more frequent.
What about taps and outlets serving operating theatres?
Every tap and water line serving an operating theatre or lab needs separate cleaning and deep disinfection.
Is cleaning one tank enough or must all tanks be cleaned together?
All tanks and the network must be cleaned together because water circulates between them. Single-tank cleaning is not sufficient.
How much does water tank sterilization in Al Abidiyah 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 Abidiyah.
