Why the job is different in Al Sarawat

Water in Al Sarawat carries faint traces of machinery oils from workshops and warehouses, a metallic taste from nearby sea salt, a pattern unseen in purely residential neighbourhoods. The method is set out in full on the full Water tank cleaning page.

The first reason

Light oils from machinery and servicing

Workshops and warehouses around your tanks use machinery and industrial oils. Water may carry a faint oil smell and hydrocarbon traces. Stronger disinfection and repeated rinsing become necessary.

The second reason

Sea salt and high humidity stress

Al Sarawat sits near the Southern Corniche and the sea, where air carries high humidity and salt spray. Your tanks corrode faster than in districts far inland, and cleaning requires extra care.

The third reason

Wide spacing and isolation from the main network

Al Sarawat is scattered with large gaps between buildings, wide empty land and loading yards. Your tanks may sit isolated from the main supply line, and water may stagnate in long distribution pipes.

Al Sarawat sits about 4.5 km from Al Saruriyah and about 6 km from Al Taawun.

Before treatment

The condition of the tank decides the method

An industrial district between the Jeddah Industrial City to the north and the Southern Corniche to the west, dominated by warehouses and workshops on wide plots with large gaps between buildings.

Fine brown sediment beneath shallow water

The layer on the floor

A layer of light oils and warehouse debris accumulates on the floor, requiring full drainage and deep cleaning, and sometimes special solvents for heavy oil deposits.

Light and algae

Algae is rare in Al Sarawat because salt and oils discourage growth, but mould may appear from the high humidity and damp surroundings.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall layer is oil and salt combined, and pressure washing works well but heavy oils may need special degreasers to lift completely.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may appear from salt corrosion of the metal structure. Regular inspection for rust and cracks is more necessary than in inland districts.

The lid and the access hatch

Covers and hatches need protection from salt and oils. Seals need frequent replacement because salt speeds their decay much faster than in sheltered areas.

The vent and the overflow pipe

Ventilation and overflow openings may carry salt and oils. A strong filter on the vent is essential, and the overflow may need separate cleaning because oils accumulate there.

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.

The character of Al Sarawat

Industrial area: workshops, warehouses and loading yards

Al Sarawat tanks serve both workshops and homes, meaning heavy mixed use and diverse contaminants. Cleaning must focus on removing oils and salt together, not just fine sediment alone.

Questions about this district

Faint oil smell comes from workshop and residential water alike, is it safe to use?

Light oil traces from nearby machinery are normal in Al Sarawat. The water is safe but deep disinfection and repeated rinsing reduce the smell. Activated charcoal filters help considerably.

Water has a strong metallic taste from sea salt and the nearby corniche?

Al Sarawat is close to the corniche and open sea, where salt air enters the tank through ventilation openings. Disinfection reduces the effect but may not remove it completely.

Do high humidity and salt in the air damage the internal metal of an old tank?

Salt air and high moisture speed internal corrosion. Regular inspection for rust inside and outside is necessary more than in districts far inland.

Workshop water and residential water look different in colour sometimes, is it one tank?

If one tank serves both, workshop pipes may have lower pressure and release older water first. Checking consumption points and water pressure is essential to understand distribution.

First water from the tap after days without use is cloudy and smells strange?

Al Sarawat is scattered and pipes are long. Water may stagnate in the distribution lines, and running off the oldest water before use is wiser than using stagnant supply.

Should warehouses and workshops have a separate tank from the residential part?

Separation is preferable but rarely built in existing schemes for cost. Frequent cleaning and stronger disinfection is the working answer for a shared tank.

How much does water tank cleaning in Al Sarawat 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 Sarawat.
