Why the job is different in Al Thaalibah

Tanks here accumulate finer silt and clay deposits faster than new districts, because the old water network carries suspended particles year round and pressure changes shift sediment loose. The method is set out in full on our Water tank cleaning service.

The first reason

Crowded water and shared pipes

Buildings stand close together and pipework runs shared between dozens of flats. A single tank serves multiple floors and water pressure fluctuates daily. Cleaning here must account for the heavy load on the tank and the continuous demand, not just one household's usage pattern.

The second reason

Silt and fine suspended matter

The old network in this quarter carries clay particles and fine silt throughout the year. The tank accumulates these deposits on its floor faster than in newer zones. High pressure washing alone is not enough; deep cleaning is needed to lift hardened silt from the floor.

The third reason

Patchy services and port proximity

The area lies between the Islamic Port and industrial zones, with high humidity and municipal services that do not reach everywhere. Apartment tanks here are exposed to moisture, mould and strange odours from shipping and saltwater spray that require strong disinfection.

The character of Al Thaalibah

Apartment district: residential blocks, repeated floors and shared entrances

Flats stacked inside apartment blocks mean the tank is not owned by one family alone. Water weakened by residents on one floor affects the households above and below. Cleaning must leave the water drinkable and safe for dozens of residents simultaneously.

Before treatment

The condition of the tank decides the method

An old unplanned quarter in south west Jeddah within slum clearance zones, marked by crowded low rise buildings, patchy municipal services, and old trunk mains running directly beneath the neighbourhoods.

Fine brown sediment beneath shallow water

The layer on the floor

The floor of the shared tank traps fine silt and sand from the old network, and sediment hardens quickly in tanks under heavy continuous use and pressure changes.

Light and algae

Light barely reaches tanks buried under apartment blocks, and black mould grows fast on damp walls because humidity from the sea stays trapped inside the structure.

The deposit on the wall

Tank walls carry a green film of algae and biological slime that clings quickly and needs hard scrubbing to remove, as it thrives in the constant darkness and moisture.

A concrete surface with a fine hairline crack

The lining and hairline cracks

The internal lining of older tanks may hold hairline cracks from repeated pressure swings and the constant moisture that seeps around foundations near salt water.

The lid and the access hatch

The tank lid and access hatch may be corroded stiff or rusted tight from coastal humidity and salt in the air, making opening difficult and inspection slow.

The vent opening may be blocked by mould and trapped insects, and the overflow pipe needs separate cleaning to ensure it does not clog and cause backpressure during filling.

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.

Landmarks of Al Thaalibah

Al Thaalibah sits between King Khalid Road and Al Falah Road, and our work covers all the apartment blocks and shared tanks within this zone. On King Khalid Road especially, where larger shared tanks serve entire buildings, we coordinate closely with building managements to schedule cleaning.

Questions about this district

Water pressure in the flat is always weak. Does it come from the shared tank?

Yes. In crowded apartment blocks a single tank serves many floors and pressure drops on upper storeys. Cleaning may improve pressure slightly if sediment clogs the outlet, but the problem usually lies in tank size and user numbers, not the tank condition itself.

How often should we clean the shared tank serving dozens of flats?

Shared tanks under heavy continuous load need cleaning every four months at minimum. The heavy user load and constant flow causes sediment to build up much faster than in single household tanks.

Water from shared pipes sometimes smells strange. Is that normal?

Old shared pipes and the constant cycling of hot and cold water harbour bacteria. Cleaning and disinfection help, but the smell may return if the problem lies in the pipes themselves rather than the tank.

Our new flat is in an old building and the water runs red. Why?

Old pipework and the older tank release iron oxide. Cleaning and disinfection help, but you may need better filtration or replacement of the internal pipes to the flat itself.

Does cleaning the shared tank mean cutting water off to every flat at once?

Yes. Cleaning a shared tank requires the water to be shut off to all residents. Coordination with building management and advance notice to tenants is essential to avoid complaints and disruption.

Humidity around the tank on the lower floor is very high. Is that dangerous?

Yes. High humidity near the sea and drainage causes slow leaks and corrosion of the tank structure. Cleaning must inspect walls and floor for small cracks before disinfection, as moisture accelerates damage.

How much does water tank cleaning in Al Thaalibah 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 Thaalibah.
