Water tank cleaning in Al Faisaliyah Jeddah

Al Faisaliyah is an older central district of northern Jeddah where dense apartment buildings dominate with villas between them. King Fahd Road runs through it, and Sari Street is its commercial spine lined with restaurants and banks. Bugshan Hospital and a University of Jeddah campus are among its landmarks. Tanks here are old and serve crowded apartment blocks filled with furnished flats and permanent residents. The water and sewerage networks are very old and require continuous maintenance and specialist attention.

Potable-rated materials

Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
You get the downtime first

How many hours the tank is out of service, told before we start rather than after we finish.
A first-draw flush

We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
Ground and roof tanks

Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Al Faisaliyah

A single block may hold twenty flats or more, usage is uneven and very high, and tanks in the upper floors run low and slow as lower flats draw more than the ageing tank can sustain. The method is set out in full on the full Water tank cleaning page.

The first reason

Dense blocks and old tanks endure constant pressure

One block may house twenty or more flats with hugely variable consumption patterns and total demand far above what the old tank was designed for. Sediment buildup reduces effective capacity further, creating a cycle of declining pressure and service.

The second reason

Furnished flats and restaurants below carry different contaminants

Furnished flat districts surround markets, restaurants and bars. Steam and light oil vapours rise towards tanks, and hot water from kitchens leaves salt deposits on pipe walls and tank surfaces.

The third reason

The very old network rusts internally and carries scale

Very old pipes rust internally, iron particles enter tanks with incoming supply, and the water emerges tasting of metal and sometimes carrying a faint reddish tint.

Before treatment

The condition of the tank decides the method

One of the oldest established districts north of Jeddah with residential blocks built decades ago. Water and sewerage networks are old and in continuous decline. Sari Street and its surroundings host dense restaurants and popular markets that place constant pressure on utilities.

Fine brown sediment beneath shallow water

The layer on the floor

Tank floors in Al Faisaliyah carry thick black silt from iron particles and metal oxides from the old network. Repeated powerful flushing removes this silt, but it returns quickly.

Light and algae

Light is limited in tanks inside old buildings, but poor moisture and ventilation speed bacterial growth and biofilm on walls.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls carry thick iron oxide layers built up over decades. High pressure washing removes surface layers, and mild acid treatment may be needed for deep deposits.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are common in very old tanks from repeated expansion and contraction. Careful inspection is essential before pressure cleaning, as re lining may be required.

The lid and the access hatch

Tank lids and access hatches in old blocks may be rusted and weak. Cleaning includes inspection of these parts and replacement of gaskets and weak components.

The vent and the overflow pipe

Vent and overflow openings in old buildings may be blocked with debris and insects. Cleaning includes full clearing of these openings and installation of fresh insect screens.

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 Airport Sub-Municipality

The Airport sub-municipality covers some of the oldest established districts of northern Jeddah, gathered around King Abdulaziz International Airport between Madinah Road, King Fahd Road and Prince Majid Road. The stock is villas, single family houses and apartment blocks built decades ago, many served by ageing water and sewer lines. Commercial streets such as Quraish, Sari and Sultan bin Salman are lined with restaurants, furnished flats and popular markets. Dense commercial kitchens, worn pipework and the gaps in older buildings give cockroaches and rodents steady food and shelter, and the high resident population keeps that pressure constant through the year.

Questions about this district

The Al Faisaliyah flat has water cuts on the fifth floor every day?

The block tank is old and undersized for current consumption. Sediment reduces capacity further. Cleaning restores some lost capacity and pressure improves slightly.

Water from the flat has a very strong metallic smell?

Old pipes rust internally very fast, and rust particles enter the tank with incoming supply. Tank cleaning removes accumulated rust, but the root cause lies in the pipes themselves.

A restaurant sits below the flat and the water sometimes smells of cooking?

Steam and light oil vapours from the kitchen enter the tank via vent openings. Cleaning cleans the tank but the problem returns. Protection from cooking smoke and steam is better.

The flat is on the third floor and hot water runs very slowly?

Rising pipes are old and narrowed by rust, and the tank may run at low pressure. Cleaning helps slightly, but the real cure is pipe replacement.

Black water runs from the tap in the morning after supply cuts?

Old pipes trap black sediment of rust and metal oxides. When supply cuts the sediment settles, and pours out on restart. Cleaning reduces this effect.

The Al Faisaliyah building is very old and so is the tank. Will it withstand high pressure cleaning?

Very old tanks may have weakened walls. Cleaning with moderate, careful pressure is necessary. Inspection before cleaning reveals the tank's true condition.

How much does water tank cleaning in Al Faisaliyah 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 Faisaliyah.
