Water tank cleaning in Al Shati Jeddah

Al Shati is a coastal northern district on Jeddah Corniche with seafront hotels and landmarks facing the Red Sea. Salt laden air and high humidity and mineral salts from the sea water penetrate tanks and cause rapid metal and seal corrosion. Your tanks here need special care because coastal conditions accelerate every type of corrosion.

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.

Why the job is different in Al Shati

Tanks on the shore are exposed to very high humidity and constant sea salt, and seals and metals rust much faster than in inland districts. The method is set out in full on Water tank cleaning in detail.

The first reason

Salt laden air enters every opening and accelerates all corrosion

Air from the sea is saturated with salt and moisture, entering through vent openings and small cracks and depositing on tank walls. All metals corrode from sea salt much faster than in any other location.

The second reason

High humidity year round prevents any drying time

Unlike inland areas where surfaces dry in the sun, the shore stays damp all year. Continuous moisture causes unceasing corrosion of seals, metals and tank linings.

The third reason

Mineral salts crystallise and block openings

Salt crystallises on surfaces and vent openings and caps, blocking airflow and stressing seals. The crystallisation causes cracking in metals and rubber seals.

Before treatment

The condition of the tank decides the method

A coastal district on the corniche between King Abdulaziz Road and the sea, with seafront hotels, the floating Al Rahmah Mosque, Red Sea Mall and the open air Al Shati Market, with villas and hotel apartments behind the seafront.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment here contains sea salt and rust particles, is more stubborn and harder to remove than inland sediment.

Light and algae

Algae grows fast because of moisture and salt content, and water may turn green much faster than in inland locations.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall deposit forms from crystallised salt and light rust, and washing walls releases a strong salt smell.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks widen as salt crystals form inside them, causing internal pressure that spreads cracks.

The lid of a water tank on a building roof

The lid and the access hatch

Metal lid seals corrode fast from salt and moisture, and you may see water trickling at edges or red rust staining around vent openings.

The vent and the overflow pipe

Vent and drain pipes corrode both inside and outside, and may crack from salt crystallisation inside them.

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 Shati

Coastal area: high humidity and salt air through the year

A coastal area means the tank faces constant attack from salt and humidity on every surface. Cleaning alone is not enough. You need extra protection, regular inspection and frequent replacement of seals and metals to give the tank a reasonable working life.

Questions about this district

Why do metal lids rust so fast on the shore?

Salt and moisture attack metals together, and the moisture never dries on the coast. You may need to replace metal lids every six months instead of annually.

Does the water sometimes taste salty?

Yes, especially after strong coastal winds. Salt enters tank openings and the water may acquire a faint salty taste.

Does plastic tank lining survive salt and humidity?

Plastic lining degrades quickly from sunlight and salt. You may need to replace lining every three to four years on the coast.

Why do vent openings clog so fast here?

Salt crystallises on openings and high humidity makes the crystallised salt stick hard. You may need to clean vents every month.

Does frequent cleaning help reduce salt problems?

Yes. Regular cleaning removes salt before severe buildup occurs. You may need cleaning every three to four months instead of annually.

Do we need extra protection for coastal tanks?

Yes. A protective coating for metals or a shade cover over the tank can help. Regular inspection and seal cleaning is essential.

How much does water tank cleaning in Al Shati 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 Shati.
