Water tank sterilization in Mushrifah Jeddah
Mushrifah is a mixed residential district crossed by main roads with dense rental apartment blocks, shops and medical complexes. Tanks here accumulate sediment rapidly because pressure in the public network fluctuates and water passes through aging pipelines. Sterilization must focus on removing biofilm from tank walls before any chemical treatment.
-
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 Mushrifah
Apartment buildings here range in age from the 1980s to the 2000s, and most use both underground and overhead tanks. The method is set out in full on what Water tank sterilization involves.
Underground tanks beneath dense apartment blocks
Rental buildings here are built close together and underground tanks sit directly beneath ground floors. Soil moisture and groundwater levels are high, accelerating biofilm formation.
Aging pipes from the city network
Main pipelines beneath Madinah Road and King Fahd Road are old and corroded. Sediment from the network enters tanks directly. Pressure varies daily, especially during peak hours.
Medical centres require higher sterilization standards
Hospitals and clinics in the district demand strict water quality standards. Tanks here need regular scheduled sterilization, not just on-demand treatment.

Open in Google MapsWhat we read inside the tank before anything starts
A densely populated inland district intersected by Madinah Road, King Fahd Road and Prince Majid Road, with apartment buildings, rental units, medical centres and shops. It is bounded by Palestine Street to the south and Gharnatah Road to the north, with Makarona Road running through it lined with commercial outlets.
Sediment on the floor
Clay and mineral sediments accumulate at the base from aging pipes and fluctuating pressure.
The slime film on the wall
Black and green biofilms coat walls and floors, especially in corners and damp zones.
Light and heat
Flushing from the main entry point reveals sediment blockages in distribution lines.
The lining and any cracking
Groundwater moisture and seepage from soil affect water quality and underground tanks.
The lid and the openings
Underground tanks partially submerged in groundwater accelerate contamination and bacterial growth.
What shows up at the tap
Water stagnant in distant lines may retain sediment.
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 Mushrifah
Apartment district: residential blocks, repeated floors and shared entrances
Dense apartment blocks close together mean deep underground tanks below ground floors. Groundwater moisture is high here and sediment accumulates quickly, so sterilization requires strong mechanical removal before chemical treatment.
Questions about this district
Why do underground tanks in apartment blocks here blacken faster than in villas?
Dense buildings, sealed ground floors and high groundwater accelerate algae and biofilm growth. Sediment from the network accumulates rapidly.
Do black biofilms in the tank mean the water is unsafe?
Yes. Biofilms harbour bacteria and fungi that affect water quality. They must be removed mechanically before chemical sterilization.
How often should the tank be sterilized here per year?
Dense buildings and aging pipes need sterilization at least every three to four months.
Does fluctuating network pressure affect water quality?
Yes. Low pressure allows contaminants to enter from pipes and neighbouring tanks. This increases the need for regular sterilization.
Is sterilizing only the overhead tank enough if the underground tank is contaminated?
No. Both tanks must be sterilized together, focusing on the underground tank first as it is the main water source.
Do medical centres require different treatment?
Yes. Medical centres need stronger and more frequent sterilization. Water lines must be tested after treatment.
How much does water tank sterilization in Mushrifah 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 Mushrifah.
