Water tank cleaning in Bathaa Quraish, Makkah

Why the job is different in Bathaa Quraish

Tanks here serve mixed use (residential, commercial and government), and irregular consumption patterns produce varied and discoloured sediment layers. The method is set out in full on Water tank cleaning in detail.

The first reason

Shops, homes and government offices sharing one tank

One building may hold restaurant and clothing shops, apartments and even government departments. Each use leaves different sediment: cooking oils from restaurants, fibres and dust from shops, and mineral traces from government water use.

The second reason

Jabal Thawr rock face and arid exposure

The rocky Jabal Thawr slope close by raises ambient temperature and dryness around the tank, concentrating minerals rapidly and salts accumulating on walls. Night time condensation and heat cycling cause rapid oxidation of metals.

The third reason

Fourth Ring Road traffic and vibration stress

The busy fourth ring road nearby creates constant vibration. Small cracks develop in tank piping and joints, and exhaust dust enters through vent openings.

The character of Bathaa Quraish

Mixed district: shops at street level with homes above them

In a mixed use neighbourhood like this, the tank is not simply domestic infrastructure but shared among residential, commercial and government users.

Before treatment

The condition of the tank decides the method

The Fourth Ring Road cuts through linking the holy sites eastward to the Jeddah expressway westward. Jabal Thawr separates it from Al Hijrah, and the district houses the Grand Mosque Library, courts and government offices.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer is mixed and discoloured with varied sediments: brown from oils, white from minerals, grey from dust and fibre.

Light and algae

Algae is present but mixed with anaerobic bacteria. Darkness and odour indicate damp heat and stagnation together.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits are a mixture of white and brown from calcium and oxides, firmly bonded by heat and dry air.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Concrete lining may have small stress cracks from vibration and thermal cycling, and may leak slowly.

The lid of a water tank on a building roof

The lid and the access hatch

The lid gets very hot in summer and undergoes rapid expansion and contraction, and the maintenance hatch may be hard to clean of baked deposits.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent openings are clogged with road dust and cooking oil fumes, and need stainless mesh filters.

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 Shawqiyah Sub-Municipality

Al Shawqiyah sub municipality runs south from the Third Ring Road to the city's edge on the Al Layth road and the Jeddah expressway. Planned districts such as Al Shawqiyah, Al Malik Fahd and Bathaa Quraish have wide streets, villas and apartment blocks, while schemes in Wali Al Ahd are being built out and informal housing in Al Ukayshiyah and Al Zuhur is being cleared. The vegetable market and livestock auction at Souq Al Halaqa, open construction sites, the rocky slopes of Jabal Thawr and sewers still being laid through the southern fringe offer exposed food, shelter and moisture.

Questions about this district

Does a tank serving shops and flats together get dirtier water?

Yes. Cooking oils from restaurants, fabric dust from shops and mineral traces from varied commercial use each add different sediment types, making the water complex.

There is a cooking oil smell from the restaurant below, does this affect our water?

Oil fumes may enter through shared vent openings. You may need to separate air ducting or fit fine mesh filters on vent grilles.

Does the heat from Jabal Thawr nearby affect our tank?

Yes. Heat accelerates oxidation and mineral concentration. The tank may benefit from thermal insulation or a shade structure in summer.

Does the ring road traffic vibrate our tank and pipes?

Yes. Vibration from heavy vehicles may cause small cracks in joints that leak slowly. Regular inspection is necessary.

How often should a mixed use tank like ours be cleaned?

Every two to three months because of varied usage, different sediment types, heat from the surrounding rock and vibration stress.

Should we separate the tank serving the shop below from ours?

If oil smell persists, separate plumbing for shop and residential may help. But mesh filters on shared air vents may solve the problem more cheaply.

How much does water tank cleaning in Bathaa Quraish 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 Bathaa Quraish.
