Why the job is different in Al Haram

Tanks here endure daily consumption loads of unusual intensity, speeding up sediment and contaminant buildup on the floor and walls far beyond what residential areas see. The method is set out in full on our Water tank cleaning service.

The first reason

Relentless consumption pressure from towers and hotels

Hotels and commercial buildings are not homes. Water falls at high velocity from tanks at extreme heights, causing particles to settle faster and accumulate more rapidly than they would in ordinary residential districts with normal usage patterns.

The second reason

Water quality from the network is different here

Water in Al Haram travels through an extended, pressurised network and carries higher loads of mineral particles and silt during peak hours than residential areas, especially where demand spikes suddenly.

The third reason

Hotel tanks are complex and interconnected

Large hotels run distributed tank systems across multiple levels with pressure-balancing pipes and feed tanks. Cleaning requires understanding the layout, the flow dynamics between levels, and how debris moves through interconnected reservoirs.

The character of Al Haram

Commercial area: offices, showrooms and small stores

A commercial area of offices, showrooms and storage means most tanks are oversized and hold large capacities, requiring specialised cleaning with heavy equipment and trained crews familiar with working at height and managing high pressure safely.

Before treatment

The condition of the tank decides the method

The uninterrupted flow of visitors and residents through the Grand Mosque and its surrounding towers creates constant, intense demand on water networks and storage that few other areas experience.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment on the floor of Al Haram tanks is often sandy and heavy from the particular water quality, requiring powerful suction and repeated washing cycles.

Light and algae

Light penetrates some transparent or shallow tanks, allowing algae to grow fast. Cleaning removes algae and the biofilm that builds on exposed surfaces.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Old steel tank walls accumulate layers of iron oxide and salt deposits that pressure washing strips away effectively, restoring the surface.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks in very old tanks need careful inspection before high pressure cleaning, as they may require re lining or structural repair.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and access hatches on tall towers require safe height equipment to reach. Cleaning requires secure sealing for the duration of the work.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent openings and overflow pipes collect dust and insect nests. Cleaning includes these external parts as part of the full tank system.

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.

What is different about Al Ghazza Sub-Municipality

Al Ghazza sub municipality wraps around the north and west of the Grand Mosque, from Al Shamiyah, Al Qararah and Shaib Amir round to Jarwal and Al Taysir. Large tracts were cleared for the northern expansion and the Rua Al Haram scheme, leaving excavated ground and open construction sites beside ageing blocks that now serve as dense seasonal lodgings in Jarwal and Al Taysir. Old flood paths still fall from Jabal Qaiqaan and Jabal Khandamah towards the mosque, and markets and eateries crowd Al Masjid Al Haram Road and Umm Al Qura Road.

Questions about this district

The hotel is full of guests and water fails in the upper floors?

Intermediate tanks on higher levels may be clogged with sediment, reducing effective capacity. A full cleaning restores capacity and returns pressure balance throughout the tower.

Water turns cloudy right after we cleaned the tank. Is that normal?

Yes. High pressure cleaning lifts dust and particles from walls and the floor. Run the tank for a few hours and the water clears as fresh supply flushes through.

Do the towers here need a different cleaning method than other buildings?

Yes. Tank height changes pressure dynamics and flow speed. Steel pipework accumulates metal oxide and mineral scale that needs stronger pressure and acidic treatment.

Visitors arrive in waves. Do we clean the hotel tank after each group?

No. One cleaning every few weeks is enough if the hotel manages the tank well, but higher consumption shortens the intervals between cleanings.

The Grand Mosque and hotels consume enormous amounts of water. Who pays for tank cleaning?

Each building maintains its own tanks. Hotels pay for their own, apartment blocks pay for theirs, and each responsibility is separate.

A giant tank on the roof bakes in the sun all day. Does that affect the water?

Heat speeds up biological growth and makes the water more vulnerable to contamination. Regular cleaning slows that decay and keeps the water fresh for longer.

How much does water tank cleaning in Al Haram 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 Haram.
