Why the job is different in Al Rabwah

Tanks in older Al Rabwah accumulate mixed deposits because pipes of different ages shed different corrosion patterns, sending rusty silt mixed with organic residues that often includes larger metal particles than newer areas. The method is set out in full on Water tank cleaning in detail.

The first reason

Old pipes send multicoloured sediment deposits

Al Rabwah's pipes were laid decades ago, so different pipe segments from different periods corrode at different rates. Brown rust, white oxide and grey scale mixture inside tanks, and you may find relatively large metal particles in the floor sludge that newer pipes don't shed.

The second reason

Mixed use means uneven consumption and intermittent flow

Shops and homes together mean some pipes bear intense use during business hours and others sit static at night. This uneven pattern causes irregular sediment buildup, and some tanks may need cleaning more frequently than others in the same block.

The third reason

Small cracks admit unfiltered groundwater and soil

Aging pipes in Al Rabwah may have tiny cracks that leak soil water or allow particles past the inlet filters. This raises the suspended solids and bacterial load reaching the tank beyond what new infrastructure would pass.

Before treatment

The condition of the tank decides the method

The district lies between King Fahd Road and Hira Street, one of northern Jeddah's longest settled areas where main pipes are decades old and in places prone to leaks and corrosion.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in old Al Rabwah tanks is highly varied because pipes from different eras shed different metals, and you may find grey, brown and even black deposits mixed together, a signature of layered corrosion sources.

Light and algae

Light and algae grow at moderate rates in exposed tanks, but old pipe water may carry more organic matter that encourages unusual algae species.

The deposit on the wall

Walls hold thick mixed layers of calcium and rust that are difficult to remove in older tanks because deposits have accumulated across decades and bond chemically.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings in very old tanks are already compromised, with cracks that are not hairline but visible, allowing insects and external water to enter easily.

The lid and the access hatch

Tank lids and access hatches in Al Rabwah are very old, seals and hinges are heavily corroded, and replacement may be necessary rather than repair.

The vent and the overflow pipe

Vent holes and overflow pipes may be heavily clogged from years of neglect and need thorough cleaning beyond just screening because accumulated debris is deep and compacted.

How we work

1
Inspect before the drain

Tank type and material, the condition of the lining, the depth of the sediment, the lid and the vent, and where the drained water will go. We agree the window without supply before anything is opened.
2
Drain, then lift the sludge

The water leaves through the outlet, then the layer beneath it is taken out by hand and by suction. That layer is the reason for the visit, not the water that ran out ahead of it.
3
High pressure wash

Walls, floor and the joint where they meet, with a brush wherever the film resists, then the wash water is taken out completely so nothing we lifted settles again.
4
Disinfect and put back in service

Disinfectant over every internal surface, left for its contact time and then rinsed out, followed by the refill, a first draw off at the taps, and a report on what was inside the tank.

What water tank cleaning includes

An inspection before the valve

Tank type, lining condition, depth of sediment, lid and vent, recorded before any water leaves.
Full drain and sediment removal

The water through the outlet, and the layer below it by hand and by suction until the floor itself is showing.
Pressure washing walls and floor

High pressure across the surfaces and corners, and a brush on anything water alone will not lift.
Disinfection after the wash

A disinfectant intended for drinking water tanks, named to you before it is used, left for its contact time and then rinsed out.
Refill and the first draw off

We refill, run the taps so the new water moves through the pipework, and tell you when it is ready to use.
A report and the next date

What was inside the tank, anything on the lid or the lining that needs repair, and a sensible date for the next clean.

The character of Al Rabwah

Mixed district: shops at street level with homes above them

In an old mixed neighbourhood, a single tank may have served residential and commercial use for decades, accumulating complex sediment layers. Cleaning must be thorough and deep to remove years of accumulated deposits that have compacted and chemically bonded to tank surfaces.

Questions about this district

Why does water in the old house foul faster than in a new one?

Aging pipes in old properties corrode and shed more metal sediment than new ones. Older tanks may also have corroded linings that leach metals into the water.

Water from the ground floor shop seems different. Is that normal?

Yes, shops may use water for different commercial purposes and may introduce substances into the line. Cleaning the main tank and fitting outlet filters improves quality.

Can the leak be from the tank itself or from the pipes?

If you notice damp around the tank base or water loss with no apparent use, the tank itself may be leaking. Older tanks develop cracks from decades of thermal expansion and contraction.

What should we do if the water has a strong rusty or iron smell?

The smell comes from pipe or tank corrosion. Tank cleaning helps but if the smell returns quickly the problem may be in the main pipes, and regular inspection is needed.

The tank sometimes has tiny black particles. What are they?

May be rust particles from old pipes or crumbling lining debris. Could also come from cracks in underground pipes letting soil particles enter the system.

Does tank cleaning improve water taste if it tastes metallic?

Cleaning removes old deposits already in the tank, but if metallic taste persists the issue is in the pipes. You may need an outlet filter or sections of pipe replaced.

How much does water tank cleaning 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.
