Why the job is different in Al Kandarah

Tanks in this zone carry thick layers of brown and black sediment, not just green, because fine dust from neighbouring warehouses and food service finds its way in through gaps and broken covers. The method is set out in full on how we approach Water tank cleaning.

The first reason

Heavy sediment from commercial activity

Al Kandarah tanks are not merely exposed to ambient humidity but to fine dust and particles from surrounding warehouses, restaurants and hotels. These particles penetrate cracked covers and settle faster than natural sediment alone. A tank here fills with both mineral scale and industrial dust, requiring stronger mechanical removal.

The second reason

Bacterial load from food and water reuse

Restaurants and shops draw water directly from tanks for cooking and cleaning, introducing bacteria from food handling and commercial sanitation. Disinfection here is not a luxury but a health requirement. Regular testing is often needed to confirm bacterial counts have fallen after cleaning.

The third reason

Stress on tank structure from intensive use

Commercial activity draws water around the clock, subjecting the tank to constant pressure swings, repeated draining and refilling. This accelerates lining decay and encourages seeping and corrosion. Tanks here show visible damage earlier than residential equivalents and may need structural assessment.

Landmarks of Al Kandarah

In Al Kandarah, tanks crown the hotels and commercial buildings along King Fahd Road and near the Kandarah Souq. Access is through the main entrances of hotels and commercial premises, and we orient ourselves using Jeddah National Hospital as a reference point in this congested district.

Before treatment

The condition of the tank decides the method

Al Kandarah sits on King Fahd Road and Old Makkah Road, a mix of hotels, older apartment blocks and dense shops and small warehouses, all experiencing high humidity from nearness to the Islamic Port and the refinery.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer at the bottom of Al Kandarah tanks is heavier and darker than others, a mixture of natural minerals and fine industrial dust from the surrounding commercial activity.

Light and algae

Algae is less common here than bacteria, because intensive use and organic food wastes feed bacterial colonies faster than algae growth.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The deposit on walls contains minerals, salts and dust particles, not just algae, requiring high pressure and strong mechanical removal rather than chemical washing alone.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Tank linings in commercial settings suffer stress faster than residential ones do, and hairline cracks appear sooner from the heavy and constant use.

The lid of a water tank on a building roof

The lid and the access hatch

Covers and access hatches here are often entirely missing rather than merely damaged, allowing dust, insects and birds unrestricted entry.

The vent and the overflow pipe

The vent opening and overflow pipes may be completely blocked by industrial dust, causing overflow floods when the tank fills quickly during peak demand hours.

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 Balad Sub-Municipality

Al Balad sub municipality covers the historic core of Jeddah and the districts that first grew outside its wall. Its building stock is the oldest in the city: heritage stone houses and apartment blocks from past decades, threaded with hotels, shops and crowded popular markets around Bab Makkah, Bab Sharif and the Kandarah Souq. Nearness to the sea, the Islamic Port and the Arbaeen lagoon keeps humidity high all year, water and drainage networks are old, and narrow lanes, dense eateries and commercial storerooms put food and shelter within reach at every corner.

Questions about this district

The hotel tap water smells odd. Is it coming from the tank?

Often yes. Commercial hotel tanks draw activity from kitchens and cleaning. Full tank cleaning and disinfection removes the smell and protects the hotel's reputation with guests. This is a financial issue as well as a hygiene one.

How often must a restaurant tank be cleaned?

Commercial restaurants and hotels need cleaning far more often than residential homes. Every two or three months is common, rather than every six. Intensive use drives faster sediment and bacterial buildup.

Must the shop shut down while we clean the tank?

Yes, we drain the tank completely, so there is no water for hours. Cleaning is best done in closing hours or very early morning to minimise loss of business.

The new tank water turned cloudy within days. Why?

New tanks may contain manufacturing residues: fibres and sand left from the factory process. High pressure washing on the first service strips these out, and water stays clear afterwards.

Does cleaning the tank improve water pressure at all?

Slightly, if heavy sediment was partly blocking the outlet. Clearing it does ease flow a little. But if the pump itself is weak, cleaning alone will not restore strong pressure.

Do nearby warehouses mean the tank stays dirty faster?

Yes, fine dust from warehouses penetrates broken covers and gaps. A secure lid and sealed openings after cleaning keep dust out and extend the interval until the next service.

How much does water tank cleaning in Al Kandarah 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 Kandarah.
