Water tank cleaning in Mughammas, Makkah

Potable-rated materials

Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
You get the downtime first

How many hours the tank is out of service, told before we start rather than after we finish.
A first-draw flush

We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
Ground and roof tanks

Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Mughammas

Industrial tanks empty faster than residential ones because processes draw water continuously, so sediment accumulates rapidly and gets pushed toward the outlet with every draw. The method is set out in full on the full Water tank cleaning page.

The first reason

Industrial use mobilises sediment constantly

Industrial tanks never hold still water. Processes draw continuously, so sediment from the floor is stirred up and enters the pipes with every withdrawal. Cleaning must halt all drawing operations, not simply close valves, or contaminated water reaches the outlet during the work.

The second reason

Workshop dust enters through tank openings

Workshops around tanks release dust of metal, cement and timber that enters through cracks and a poorly sealed lid. Industrial dust is heavy and settles in dense layers in the tank and the rising mains.

The third reason

Flash floods carry heavy silt to open tanks

The wadi runs very close and heavy rains carry the water level high enough to reach tank tops and vents. Floodwater is laden with thick mud and organic matter that coats the floor and walls thickly.

Before treatment

The condition of the tank decides the method

Open industrial ground crossed by Wadi Al Mughammas, which floods in heavy rain and carries heavy silt. Dust from unpaved roads and industrial operations seeps constantly into exposed tanks.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is thick and dense in industrial tanks because sediment is constantly stirred and re-settles due to heavy continuous use and pressure fluctuation.

Light and algae

Algae and bacteria grow faster in warm industrial tanks with roof exposure, particularly if water has sat for hours or days before the next draw.

The deposit on the wall

The wall deposit is red and black from rust and metal dust, a heavy accumulation of fallout from nearby metalwork and grinding operations.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks in industrial tanks multiply from heavy use and constant pressure cycling throughout the working day.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and hatch become hot in summer, causing seals and gaskets to expand and lose compression. They must be cleaned and the fasteners rechecked.

The vent and the overflow pipe

The vent becomes clogged with metal and cement dust from adjacent workshops, so it requires careful clearing to restore airflow.

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 Mughammas

Mughammas sits between Jabal Al Tariqi to the north and Wadi Al Sharai to the south, with industrial tanks located near assembly workshops and storage yards. Access is from the Al Wadi Al Akhdar road or from the loading areas adjacent to Hamid Al Qathami Mosque.

Questions about this district

The water in the workshop blocks the pipes with dust every week?

Fine industrial dust settles in pipes much faster than ordinary water sediment. The tank and piping need regular cleaning, at least monthly, to prevent blocking.

The workshop tank heats the water in summer. Does that affect water quality?

Warm water accelerates bacterial and algal growth. In summer, monthly cleaning is advised instead of once every two months to manage the biological load.

Can we clean the tank while the workshop keeps running, or must it stop?

All processes drawing from the tank must stop. If drawing continues during cleaning, contaminated water flows straight to the outlet and defeats the purpose of the work.

The water in the industrial tank smells like fuel or oil. Is it a leak?

The smell may be petrol or diesel vapour or spilled oil soaked into the ground around the tank. Check the foundation and soil around the tank for contamination before cleaning.

Should industrial tanks be tested for leaks before cleaning?

Yes, because a leak means the tank is damaged and cleaning alone does not restore it. Testing confirms the shell is intact before it is refilled and put back to work.

After cleaning, how long do we wait before using the water in production?

Water is safe to use immediately after disinfection. However, old pipes may still contain aged water, so running off the mains for a few minutes first ensures fresh water reaches the process.

How much does water tank cleaning in Mughammas 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 Mughammas.
