Why the job is different in Harat Al Amir

Metal tanks rust quickly here from salt and moisture, and plastic tanks degrade faster than they would inland from salt spray and direct sunlight. The method is set out in full on Water tank cleaning in detail.

The first reason

Sea salt and moisture penetrate through every opening

Salt laden air enters through ventilation openings and small cracks, salt from the air deposits on tank walls and mixes with the water. High humidity all year causes faster corrosion of metal and metal seals than inland areas.

The second reason

Metal seals and lids corrode and perforate quickly

Sea salt attacks metal lids and corrodes them much faster than in inland locations. Rubber seals degrade from salt exposure and direct sunlight on exposed tank tops.

The third reason

Drain and vent pipes rust inside the tank from salt water

Metal pipes inside the tank rust from salt and humidity, with rust particles settling on the floor. Metal drain pipes may perforate from internal corrosion, causing water leaks at the base.

Landmarks of Harat Al Amir

In Harat Al Amir, household tanks are scattered between narrow homes close to the Thuwal Corniche and Al Shati Mosque. Access to most tanks is via the shared roof or a small back yard, and some tanks may be hidden beneath a stair or against the street side wall.

Before treatment

The condition of the tank decides the method

An old residential quarter in a small coastal town with low buildings and narrow streets near Thuwal Corniche and the fishing harbour, with high humidity year round.

Fine brown sediment beneath shallow water

The layer on the floor

The floor sediment here contains sea salt crystals and rust particles from metal surfaces, is more stubborn and harder to remove than normal sediment.

Light and algae

Algae grows fast because of the 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 walls carry a layer of crystallised salt and light rust, and cleaning metal pipes reveals rust underneath the visible surface.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks widen as salt crystals form inside them, and metal corrosion accelerates the widening of existing cracks.

The lid of a water tank on a building roof

The lid and the access hatch

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

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent and drain pipes corrode both inside and outside, restricting airflow and increasing humidity inside the tank.

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 Thuwal Sub-Municipality

Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.

Questions about this district

Why does the water look white or cloudy so quickly here?

Sea salt from the air enters the tank and settles with other sediments. Rusting metals release tiny particles that suspend in the water and turn it cloudy.

Is it normal for metal lids to rust this fast in a coastal location?

Yes. Salt and moisture accelerate corrosion many times faster than inland. You may need to replace metal lids every one or two years.

How do we protect the tank from sea salt entering it?

Check lid seals and openings regularly, and make sure vent openings have clean filters. Coating metal parts with a protective oil helps a little, but replacement is usually better value.

Why does the water sometimes taste salty?

Sea salt enters through openings and cracks, or rusting metals release mineral salts. This happens more in tanks that have not been cleaned for some time.

Can rust pipes perforate and leak from the inside?

Yes. Internal rust from salt and moisture eats through pipes, and you may see leaks from the tank base or access hatch after two or three years.

Does cleaning more often help reduce coastal tank problems?

Yes. Regular cleaning removes accumulated salt and emerging rust before it becomes severe. You may need cleaning every six months instead of annually in this location.

How much does water tank cleaning in Harat Al Amir 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 Harat Al Amir.
