Water tank cleaning in Al Mansour Makkah

Al Mansour is a densely packed commercial zone strung along Prince Mansour Street in central Makkah, where ground floor shops and offices sit beneath residential blocks that share the same water tank. The tanks here face doubled usage: heavy daytime demand from shops and offices mixed with residential needs, and the pipework serving both carries a heavier contamination load than purely residential areas.

Why the job is different in Al Mansour

Tanks here are under constant pressure from shops using water for cleaning, cooking and drainage throughout the day, with additional load from residents at night, and contamination comes from repeated washdowns by small shops and food preparation. The method is set out in full on how we approach Water tank cleaning.

The first reason

Double usage means double contamination pathways

Shops use tank water constantly for cleaning, washing and cooking, with many small eateries on site. Labour is dense and water runs all day, then the same tank serves residential needs at night. System pressure is high and sediment accumulates faster than in areas with single use, residential tanks only.

The second reason

Shared vertical pipes carry bacteria from the shops

Vertical pipes pass through both shop walls and apartment blocks, and water leaks from commercial repairs introduce humidity and bacteria into the pipework. Tank cleaning alone does not solve the problem if shared pipes are drawing contamination from shop maintenance work and seepage from the floors below.

The third reason

Old metal pipework corrodes and deposits rust particles

The old residential blocks in Al Mansour still carry corroded metal pipes from decades past, and rust flakes into the water. These metal particles accumulate on the tank floor and need deep cleaning, not just rinsing, to remove the caked layers.

Before treatment

The condition of the tank decides the method

The old commercial district mixes ground floor shops and small markets with multi storey apartment buildings, and the tanks must serve both the retail use in working hours and domestic needs in the evening and night.

Fine brown sediment beneath shallow water

The layer on the floor

The floor accumulates metal sediment from corroded pipes and congealed fats from shop and restaurant use, requiring deep scrubbing that surface washing cannot provide.

Light and algae

Light and algae are less of a problem here as tanks are usually covered, but bacteria grow rapidly from moisture and constant usage from commercial and residential sources.

The deposit on the wall

Wall deposits build up from heavy use of hot water and soap by the shops and eateries below, and the grease layer is thicker than in domestic tanks.

The lining and hairline cracks

Plastic linings in old blocks may show cracks from repeated pressure surges caused by doubled usage and thermal expansion of the old metal components.

The lid and access hatches are under constant use from frequent maintenance checks and high throughput, raising the risk that hatches are left partly open and contaminants enter.

Vent openings and overflow pipes clog quickly from sediment and grease due to the heavy water usage by shops, restaurants and residential occupants.

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 Mansour

Commercial area: offices, showrooms and small stores

In a commercial zone, the tank carries diverse and intense usage from shops, offices and homes at once.

Questions about this district

Do the commercial shops on the ground floor pollute the tank more?

Yes, shops use tank water heavily for cleaning, cooking and drainage, and wastewater from small eateries may enter the network. The shared tank carries doubled usage pressure different from residential-only housing.

Why does the water sometimes contain shiny metallic particles?

Old corroded metal pipes shed rust flakes into the tank water. Deep cleaning removes the metallic sediment layers, but complete resolution may need old pipes to be replaced.

Should we clean the tank more often because of the shops?

Yes, doubled usage and continuous demand raise sediment accumulation rates. Commercial use increases water demand and higher consumption means more frequent planned cleaning is needed.

Can we separate the shop tank from the residential tank?

Some buildings have separate tanks, but older ones share a single system. Separating them reduces pressure, but regular cleaning solves the problem if separation is not possible.

Does water from the shops below mix with water for residents above?

Pipes carry water from the tank to all locations, and pressure controls direction. But maintenance work and leaks in shops can introduce contaminants into the entire network.

Can bacteria from restaurant use enter the tank through the pipes?

Small restaurants may discharge dirty water into the network if a valve leaks or breaks. Cleaning and disinfection are essential, and pipe inspection may also be needed.

How much does water tank cleaning in Al Mansour 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 Mansour.
