Water tank cleaning in Al Muntazahat Jeddah

Al Muntazahat stretches along Old Makkah Road in south eastern Jeddah, a mixed district of villas, apartment buildings and commercial shopfronts. It neighbours Al Adl, Al Farouq and Al Fadl, with Al Muntazahat Park, schools and health centres. Tanks here face seasonal pressure swings: school holidays and public holidays cut consumption sharply, while term time and weekdays spike demand. This makes sediment unstable and floating rather than settled.

Why the job is different in Al Muntazahat

Tanks in Al Muntazahat sit very close to the main Makkah Road, meaning that vibration from car traffic affects the tank continuously, and road dust causes leaks in ventilation openings. The method is set out in full on the full Water tank cleaning page.

The first reason

Pressure swings from seasonal and school calendar variations

In Al Muntazahat, where state schools and residential blocks dominate, consumption changes sharply between term time and holidays. During long holidays consumption drops steeply and may stop altogether in some empty flats. This pressure swinging cracks the tank lining repeatedly.

The second reason

Vibration from heavy traffic on the Old Makkah Road immediately adjacent

Tanks in Al Muntazahat sit right beside the main Makkah Road, where school buses and heavy trucks cause constant vibration. This shaking widens cracks in the tank and speeds up corrosion of lining and pipes.

The third reason

Road dust enters the tank through ventilation openings continuously

Old Makkah Road is a constant dust source, especially in summer and dry seasons. Dust enters the tank through ventilation openings or wall cracks, builds up in pipes and clouds water quickly. Frequent cleaning may be needed even in summer.

Before treatment

The condition of the tank decides the method

Al Muntazahat sits along Old Makkah Road in south eastern Jeddah, with villas and apartment blocks alongside schools and health services, the main road carrying very heavy traffic throughout the day.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment consists of fine sand and brown dust from the Makkah Road, not just ordinary mineral deposits.

Light and algae

Light and algae may grow but dust coats walls with a brown layer that masks growth; cleaning reveals black algae beneath.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls are covered with brown dust and mineral film, and high pressure washing may pull dust out of cracks.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings crack from constant road vibration more than tanks in quiet districts.

The lid of a water tank on a building roof

The lid and the access hatch

Lids and hatches may be broken because maintenance in apartment blocks is not always regular, and vibration loosens fasteners.

Ventilation openings may be clogged with road dust and sand, causing air and moisture to trap inside.

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 Umm Al Salam Sub-Municipality

The Umm Al Salam sub municipality covers the east and south east of Jeddah along the Old Makkah Road and the Haramain Road. It pairs recently planned districts such as Al Wahah, Al Nakhil and Al Shuruq with popular districts that grew outside formal planning, including Al Harazat, Al Mahamid and Umm Al Salam. The older areas have ageing drainage, unpaved streets and vacant plots where building waste collects, conditions that suit rodents, cockroaches and ants. The newer areas are ringed by half built subdivisions and open excavations.

Questions about this district

Our water is very cloudy on the first day back to school after a long holiday, why?

During long holidays, consumption drops and water stagnates in the tank and pipes. When school starts and consumption suddenly rises, stagnant water and accumulated sediment are pushed through the system. Draining and flushing before school starts solves this.

Does the vibration from the heavy traffic really affect the tank?

Yes, significantly. Constant vibration widens cracks and speeds lining corrosion. If the tank sits right beside the road, frequent preventative maintenance is essential.

Our water contains dust and brown sediment, especially in summer, why?

Dust from Old Makkah Road enters the tank through ventilation openings or small cracks. In the dry summer, dust is more abundant. Covering vent openings with fine filters and sealing cracks is necessary.

How often should a tank in Al Muntazahat really be cleaned?

Given seasonal pressure swings, traffic vibration and road dust ingress, every two to three months is recommended. In summer, more frequent cleaning may be needed.

Is a larger tank better than a smaller one here for reducing sediment problems?

Yes. A larger tank means less water stagnation during low consumption periods, and sediment settles better. But cleaning remains necessary.

Should we install filters on our taps because of this dust and heavy sediment?

Yes, strongly recommended. Simple tap filters on main points reduce dust entering daily use. This improves water quality in the kitchen and bathroom.

How much does water tank cleaning in Al Muntazahat 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 Muntazahat.
