Water tank sterilization in Al Marwah Jeddah
Al Marwah is a comparatively recent district in northern Jeddah between Prince Majid Road and Al Nuzhah Road, with modern villas and new apartment buildings. Tanks here are mostly new, but have not yet reached the age of heavy sediment buildup. Water may contain debris from ongoing construction projects and residential expansion around the district.

Why the job is different in Al Marwah
Tanks in Al Marwah are newly built, but water may contain dust from new streets and ongoing construction projects around the district. The method is set out in full on Water tank sterilization in detail.
New modern apartment building tanks
Apartment buildings in Al Marwah built in recent years have new, large-capacity tanks. Dust from construction sites and new streets may introduce unusual minerals and debris.
Modern villas with sealed underground tanks
Villas in Al Marwah are newly built with well-designed underground tanks. Moisture is lower than in older villas, but water may contain sediment from modern construction.
Construction projects increase debris and dust in the water supply
Al Marwah continues to develop and expand. New streets and projects around the district increase dust and particles in the water. The water network may be linked to older systems from neighbouring districts.
The character of Al Marwah
Mixed district: shops at street level with homes above them
The district is new with modern villas and buildings, so tanks are recent and well-designed. However, ongoing construction projects around Al Marwah increase debris in the water network. Treatment focuses on removing recent sediment and building-related debris rather than algae and aged contaminants.
What we read inside the tank before anything starts
A comparatively new district in northern Jeddah between Prince Majid Road and Al Nuzhah Road, with modern villas and apartment blocks. It borders Al Safa to the west and Al Rabwah to the east. Prince Majid Park, Uthman ibn Affan Mosque and the Al Marwah health centre are local landmarks.
Sediment on the floor
Recent sediment may contain fine dust from construction sites and unusual minerals from new projects and damaged new streets.
The slime film on the wall
Algae grows more slowly in new tanks but may appear if water stands still for extended periods.
Light and heat
New inlet pipes may be clean, but the older city network may carry aged sediment into the new tank.
The lining and any cracking
Moisture in new underground tanks is controlled, but water may carry debris from construction and new streets.
The lid and the openings
Floor inspection of new tanks reveals sediment from building materials and fine mineral particles.
What shows up at the tap
New pipes and fixtures may retain installation residue, paint and require complete cleaning and flushing.
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 Airport Sub-Municipality
The Airport sub-municipality covers some of the oldest established districts of northern Jeddah, gathered around King Abdulaziz International Airport between Madinah Road, King Fahd Road and Prince Majid Road. The stock is villas, single family houses and apartment blocks built decades ago, many served by ageing water and sewer lines. Commercial streets such as Quraish, Sari and Sultan bin Salman are lined with restaurants, furnished flats and popular markets. Dense commercial kitchens, worn pipework and the gaps in older buildings give cockroaches and rodents steady food and shelter, and the high resident population keeps that pressure constant through the year.
Questions about this district
Why do new tanks in Al Marwah need sterilization if they are recently built?
Tanks are new but water from the network may carry dust and debris from construction projects and new streets. Sediment accumulates even in new tanks.
Does construction dust affect tank assembly and water quality?
Yes. Building projects around Al Marwah increase fine dust and minerals in the water. New tanks may contain sediment from the moment they are installed.
Do new tanks need different sterilization methods than old ones?
Not necessarily, but we may first assess the type of dust and minerals present. New tanks may contain different debris from construction work.
How many times per year should a new tank in Al Marwah be sterilized?
In a district under development like Al Marwah, more than once yearly may be needed, as debris enters continuously from new projects.
Does modern construction standards mean the tank is protected from contamination?
No. The tank itself may be well-built, but the main water network may carry sediment from new streets and neighbouring projects.
Do we need to clean a new tank before sterilization?
Yes. Even new tanks contain sediment from installation and construction. We wash walls and the floor under high pressure before sterilizing.
How much does water tank sterilization in Al Marwah 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 Marwah.
