Water tank sterilization in Al Rabwah Jeddah
Al Rabwah is one of the older established districts of northern Jeddah, between King Fahd Road and Prince Majid Road and south of Hira Street, with villas on large plots and apartment buildings closely packed. Tanks here are old and heavy with sediment, some showing copper corrosion and rust in the pipes. Water quality is affected by system age and poor maintenance routine.

Why the job is different in Al Rabwah
Tanks in Al Rabwah are relatively old and contain thick sediment layers. Old copper and iron pipes cause odd taste and discoloration in the water. The method is set out in full on Water tank sterilization in detail.
Old villas with deep underground tanks
Villas in Al Rabwah are old and built on large plots, with deep, often narrow underground tanks. Soil around the tank may contain aged contaminants and moisture is high.
Copper and old pipes cause strange taste and discoloration
Pipes in old villas are copper and aged, with green verdigris building on internal walls. Iron pipes cause brownish discoloration in the water.
Mid-range apartment blocks with shared old tanks
Apartment buildings in Al Rabwah have old shared tanks serving multiple units, maintenance is poor. Thick sediment may reduce water flow.

Open in Google MapsWhat we read inside the tank before anything starts
One of the older established districts of northern Jeddah, between King Fahd Road and Prince Majid Road and south of Hira Street, with villas on large plots and apartment buildings sharing its grid. Al Bawadi lies to the west and Al Marwah to the east. Sari Street is the main commercial thoroughfare.
Sediment on the floor
Thick brown and white sediment collects on the tank floor from minerals, verdigris and rust from old pipes.
The slime film on the wall
Green algae and verdigris on internal walls result from old copper pipes and standing water.
Light and heat
Old inlet pipes are corroded or verdigris-coated and continuously increase contaminants in the tank.
The lining and any cracking
High moisture and damp soil around deep underground tanks promote algae and biological contaminant growth.
The lid and the openings
Floor inspection reveals thick, hard-to-remove sediment from rust, verdigris and heavy minerals.
What shows up at the tap
Old pipes, valves and fixtures contain internal deposits and rust and need separate cleaning or replacement.
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 Rabwah
Mixed district: shops at street level with homes above them
The district is older with aged villas and apartment buildings, so tanks and pipes are very old. The main problems are verdigris, rust and thick sediment layers. Treatment requires careful cleaning and may need pipe and fixture replacement if heavily damaged.
Questions about this district
Why does water in Al Rabwah have an odd taste and colour?
Old copper and aged pipes cause green discoloration (verdigris) and iron pipes cause brown tint. Thick sediment in the tank makes it worse.
Does cleaning the tank solve the taste and colour problem permanently?
It improves it but does not fully solve it. The old pipes are the root cause and need replacement. Cleaning removes sediment from the tank only.
Do old tanks in Al Rabwah leak through cracks?
Yes. Old tanks may have small cracks and moisture causes wall corrosion. Water may seep slowly and moisture enters from the soil.
Is chemical treatment enough to solve verdigris and rust problems?
No. Chemical treatment removes present deposits but old pipes generate new verdigris and rust continuously. Pipe replacement may be needed.
Do old villas need more frequent cleaning than new apartment buildings?
Yes. Old villas with deep tanks and aged pipes need more frequent cleaning. Sediment and verdigris accumulate faster.
How do we handle narrow, deep tanks in old villas?
We use specialist equipment and high pressure to reach deposits at the base. We may need to remove the tank or open inlet and outlet lines for full cleaning.
How much does water tank sterilization in Al Rabwah 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 Rabwah.
