Water tank cleaning in Al Aziziyah Makkah

Al Aziziyah sits on the pilgrims' route to Mina, six kilometres from the Haram on King Abdulaziz Road, a large commercial zone of hotel towers, markets and pilgrim lodgings. Tanks here are massive and sit atop a small number of tall buildings. Consumption is intensely seasonal: quiet in ordinary months and chaotic during Ramadan and Hajj, when sediment accumulates at a rate multiples of normal. A tank cleaned in September may be heavily loaded again by the Hajj four weeks later.

Why the job is different in Al Aziziyah

Tanks here are extremely large, access to them is at great height on tall buildings, and consumption changes dramatically between season and off season in ways tanks are not designed to handle. The method is set out in full on the full Water tank cleaning page.

The first reason

Extreme seasonal consumption and infrastructure stress

Al Aziziyah sits on the Hajj road, and consumption changes radically. During Ramadan and Hajj, tanks drain and refill at brutal speed. Outside season, tanks sit nearly empty. This violent swing puts extreme stress on the tank lining and piping, and sediment settles in chaotic patterns with layers forming, disturbing and re forming. A single tank may need emptying multiple times in a day during Hajj but not empty at all for a week after.

The second reason

Hotel towers and massive elevated tanks

Tanks here crown hotel buildings that may exceed 30 storeys. Tank volumes are very large to accommodate pilgrim and tourist peaks. Cleaning a tank this size at this height demands heavy equipment and a specialised crew, making costs and access constraints the principal limiting factors.

The third reason

Bus parks, markets and commercial pollution

Al Aziziyah clusters around the vast bus park and the Mahbas Al Jinn depot and dense markets. Tanks here face contamination from commercial activity and exhaust. Road dust, vehicle emissions and highway salt enter tanks through open access hatches and damaged vents.

Al Aziziyah sits about 2.5 km from Al Sanabel and about 3 km from Al Mursalat.

Before treatment

The condition of the tank decides the method

Al Aziziyah straddles King Abdulaziz Road and Al Masjid Al Haram Road, about six kilometres from the Haram on the Hajj route toward Mina, with hotel towers, markets, massive bus depots and dense pilgrim lodgings all along the road.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer in massive seasonal tanks becomes very thick after Hajj because heavy consumption and rapid re settlement of sediment happen many times per day during the peak.

Light and algae

Algae may be rare at this height, but bacterial counts can be very high from intensive use and rapid cycling.

The deposit on the wall

Wall deposits may be brown from minerals and salts from the Hajj road dust which carries desert salt.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings endure violent pressure swings and cycles, and hairline cracks form faster than in steady use tanks.

Covers may be missing or loose from frequent opening during high demand, and access hatches suffer visible damage.

Vent openings may be blocked with road dust from bus traffic, and overflow pipes may be damaged from high seasonal pressure.

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 Aziziyah

Commercial area: offices, showrooms and small stores

Commercial zone status in Al Aziziyah means your tank supplies hotels, markets and bus operations. Consumption is violently seasonal and always heavy. Road and commercial pollution enters the tank constantly. Regular professional cleaning and frequent inspection are essential to protect public health.

Questions about this district

The large hotel tower tank in Al Aziziyah, what does cleaning cost?

Tank sizes vary but cleaning may take a full day or more. Work at this height requires specialised safety equipment and a trained crew, and those constraints drive both cost and scheduling difficulty.

Ramadan is next month and the tank needs cleaning. When should we start?

We recommend cleaning at least two weeks before Ramadan. The farther from peak season, the easier the work and the better the outcome will be.

Water pressure in the hotel is weak. Could it be the tank?

It may be the tank or the very long distribution pipes. Cleaning the tank and checking the main pumps may help, but you might need stronger pumps.

Water from the market runs cloudy immediately after we clean the tank. Normal?

Yes, very normal. When a massive tank empties, sediment takes many hours to settle out in the vast network. We recommend not using water for the first few hours after cleaning.

The bus park is next to the tank. Do exhaust and fumes enter the tank?

They may enter through vent openings and open access hatches. A secure cover and sealed openings after cleaning prevent contaminant entry.

Must the entire hotel shut down during tank cleaning?

Yes, preferably. If the hotel is in season it may be difficult to shut. Coordination before peak season is much better than trying to clean during it.

How much does water tank cleaning in Al Aziziyah 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 Aziziyah.
