Why the job is different in Al Safa

Old water network pipes in Al Safa may leak internally or carry mineral sediments, and water entering the tank may not be clean because of the condition of the supply network itself. The method is set out in full on how we approach Water tank cleaning.

The first reason

Older tanks and metal pipework corroded internally over decades

Tanks installed decades ago may contain old iron pipes corroded inside. Rust byproducts enter the water turning it cloudy, and old pipes may leak from outside without obvious signs.

The second reason

Ageing water network and shared lines may carry contamination

Al Safa's water network is among Jeddah's oldest and main pipes may contain sediment or leaks. Water from other tanks or nearby drainage may enter the network at weak points.

The third reason

High population density and constant commercial usage

Al Safa is densely populated with residents, traders and restaurants, putting heavy pressure on the network. Water may cut off or lose pressure during peak hours, potentially allowing contaminants to enter.

The character of Al Safa

Mixed district: shops at street level with homes above them

An old and large district with ageing tanks means the problem may not be the tank alone but the supply network feeding it. Regular cleaning is important but solving network problems may need intervention at a higher level than just tank maintenance.

Before treatment

The condition of the tank decides the method

One of the oldest and largest districts of northern Jeddah, with villas, family homes and apartment blocks and markets along Prince Majid Road, stretching between Prince Majid Road west and King Fahd Road east, with Souq Al Murjan, Al Safa Park and Abdul Latif Jameel Hospital among its landmarks.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment here may contain metals from old corroded pipes, is heavier and harder to dissolve than normal sediment.

Light and algae

Algae is rare because tanks in older homes are usually not exposed to direct sunlight, but bacteria may grow fast if chlorine levels drop.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits contain traces from old metal pipes and may be brown stained from rust.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may be relatively large in older tanks, and rust stained metal around cracks shows where corrosion has progressed.

The lid of a water tank on a building roof

The lid and the access hatch

Lid and opening seals may be worn from years of use, and water may leak around seal edges.

The vent and the overflow pipe

Vent openings may be old and clog from moisture that has accumulated over decades.

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

Why does water stay cloudy even after cleaning?

Old iron pipes in the network release mineral sediment. The water may be cloudy from the supply network itself before it enters your tank.

Can water from other tanks enter our tank through the network?

Yes, if tanks are connected to one network without isolating valves. In an old district like Al Safa, the network may have weak points in some sections.

Do old iron pipes leak water from the outside?

Yes. Internal rust in pipes can create small holes that leak water from outside the tank. You may not notice if they are very small.

Does pressure drop at peak times allow contaminants to enter?

Yes. A sharp pressure drop can create a vacuum that pulls contaminants from nearby pipes or the ground into the tank.

Do very old tanks in Al Safa need replacement instead of just cleaning?

Some tanks may be very old and might benefit from replacement. Regular cleaning can extend their life, but replacement may be cheaper in the long run.

Should we check the external supply line too or just the tank?

If water stays cloudy all the time, you may need to check the incoming water line too. A network problem may need action from the water authority.

How much does water tank cleaning in Al Safa 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 Safa.
