Water tank cleaning in Al Misfalah Makkah

Al Misfalah is the low ground that falls away south of the Grand Mosque along Ibrahim Al Khalil Street, where closely packed old apartment blocks and hotels lodge Hajj and Umrah visitors. Tanks here sit on rooftops of very old buildings, reached through narrow interior stairs. The low-lying position brings poor drainage and water pooling, and tanks suffer relentless ground moisture and contamination from the dense surroundings. Water arrives at the tap already compromised by its passage through ageing lining.

Why the job is different in Al Misfalah

Tanks here crown very old buildings, humidity is very high because the district is naturally low lying and poorly drained, and water often arrives cloudy even before taps open. The method is set out in full on how we approach Water tank cleaning.

The first reason

Low lying position, poor drainage and flooding

Al Misfalah is naturally low, and drainage is extremely poor. When rain falls, water pools in streets and lanes. Tanks close to ground level suffer seepage from the waterlogged soil, and floods can reach the tanks themselves. This brings continuous contamination from soil water and polluted runoff. The tank cannot be cleaner than the water surrounding it, and that water is perpetually dirty.

The second reason

Relentless humidity, fungal growth and mould

The low ground holds moisture all year. Tanks endure continuous seepage from surrounding soil and saturated air. This drives rapid fungal growth and mould blooming on internal walls. Water often carries a strong smell from fungal colonies. Disinfection after cleaning may help temporarily but fungal re growth is rapid in this environment.

The third reason

Extremely old buildings and failing tanks

Al Misfalah buildings are among Makkah's oldest stock. Tanks may be metal from past decades or very weak concrete. Linings may be entirely failed, foundations may be eroded from continuous moisture. Cleaning alone may not suffice: structural repair or complete tank replacement may be necessary to restore the system.

The character of Al Misfalah

Apartment district: residential blocks, repeated floors and shared entrances

Apartment district status in the old Al Misfalah means your tank supplies very old buildings and pilgrim hotels. The low lying position adds persistent moisture and flooding challenges. Tank cleaning is necessary but may not be sufficient without external moisture control and continuous maintenance.

Before treatment

The condition of the tank decides the method

Al Misfalah is low lying ground along Ibrahim Al Khalil Street south of the Haram, with closely packed old apartment blocks, hotels and dense shops, old flood paths and very narrow lanes and passages between buildings.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer at the bottom of low lying tanks is a mixture of minerals, soil particles and contaminants from the wet soil pressing against the tank.

Light and algae

Algae may be black or green from relentless moisture and mould that grows rapidly on walls in the high damp.

The deposit on the wall

Wall deposits may be black mould or brown algae from the high humidity and poor ventilation throughout the district.

The lining and hairline cracks

Tank linings in low lying tanks corrode very fast from continuous moisture, salt and dissolved minerals in the water.

Covers are often missing or entirely failed, and access hatches are sealed shut by mud and mould growth.

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 Misfalah Sub-Municipality

Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.

Questions about this district

The water runs cloudy even after we clean the tank. What is the answer?

If continuous moisture is seeping from surrounding soil, tank cleaning alone may not solve it. The tank may need external moisture barriers, or replacement if the structure is severely compromised.

The ground floor hotel floods when rain comes. Is it the tank?

It may be. If the tank is overflowing or seeping, it can cause flooding in the flat below. Tank inspection and sealing of leaks is essential.

The water smell from fungal growth is very strong. Is cleaning enough?

Cleaning and disinfection may reduce it but not eliminate it if fungal colonies are in the soil and foundations. External moisture treatment is also needed.

The tank is leaking water toward the stone walls of the house. What is the cure?

Leaking from an old tank destroys the historic stone walls. Tank replacement or major lining repair is absolutely necessary.

Will cleaning the tank improve water pressure in this old building?

It may help slightly if sediment is blocking pipes. But if the piping itself is extremely old, cleaning alone will not restore good pressure.

The whole area suffers from moisture. Is there a permanent answer?

A lasting answer requires district level work: improved drainage, foundation raising, collective humidity treatment. Tank cleaning is only part of a larger solution.

How much does water tank cleaning in Al Misfalah 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 Misfalah.
