Why the job is different in Al Quzayn

Tanks in Al Quzayn carry a thicker white salt deposit and rust layer on their walls than any other neighbourhood in Jeddah, even through the wet winter months. The method is set out in full on the full Water tank cleaning page.

The first reason

Salt and humidity erode tanks from within

Salty sea air enters the tank through ventilation and with the incoming water supply, salt settles on the walls and traps moisture beneath it, accelerating corrosion of steel reinforcement if the tank is concrete with metal frame reinforcement.

The second reason

Permanent humidity prevents tank drying

In Al Quzayn humidity never falls, even after thorough cleaning, so the tank never fully dries and new water enters a very damp environment. This rapidly encourages salt loving algae and bacteria unique to coastal districts.

The third reason

The nearby iron factory sends fine metal particles into air

Fine iron particles from the factory enter the tank through ventilation and vents, react with salt and moisture to form an orange rust layer on walls and stain the water an amber colour.

Landmarks of Al Quzayn

Tanks in Al Quzayn stand between the very close Al Seef Beach and the Southern Corniche where access routes run, and work here demands care to protect all equipment and pipes from the intense salt spray throughout the year.

Before treatment

The condition of the tank decides the method

The location sits directly beside Al Seef Beach, a sewage treatment works and an iron factory, with extremely high salty humidity that attacks every metal and concrete surface continually.

Fine brown sediment beneath shallow water

The layer on the floor

The layer on the floor in Al Quzayn tanks is damp and often firmly bonded, mixing salt, silt and moisture together into a resistant paste.

Light and algae

Light is dim in coastal tanks and high humidity speeds the growth of salt loving algae on walls and floor.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls bear a white salt layer, red iron deposits and green algae all together, and need deep chemical cleaning and scrubbing to remove fully.

A concrete surface with a fine hairline crack

The lining and hairline cracks

The concrete lining cracks from salt crystallisation and constant moisture, and the hairline breaks let more salt and damp penetrate deeper into the tank structure.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and access ports in Al Quzayn are often stuck fast from salt and humidity buildup, making opening and servicing very difficult.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent and overflow openings in the coastal zone offer no protection from salt, as salty air drives straight through even simple vents.

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 South Sub-Municipality

The South sub municipality runs from the edge of Old Makkah Road down to Al Khumrah and the southern corniche. Dense residential districts sit beside new subdivisions such as Al Sanabil and Al Taawun, warehouse fringes such as Al Saruriyah and Al Sarawat, and an old seaside settlement at Al Quzayn. Open stormwater channels cross the housing, and the warehouses, the vegetable and livestock markets and the nearby Islamic Port and Industrial City give pests shelter, food and year round humidity. Pressure is greatest in the older quarters, where drainage networks are ageing.

Questions about this district

Water from our tank in Al Quzayn has a very strong salt smell from the sea. Is the tank contaminated?

The salt smell comes from salty sea air entering through ventilation openings, not from sea water intrusion into the tank. Cleaning removes accumulated salt but the smell returns unless ventilation and filters are improved.

Water runs slightly reddish from the tap in summer. Where does that come from?

Fine iron particles from the nearby iron factory enter through air and water supply, and iron deposits on tank walls increase in heat and high humidity during the summer months.

Humidity around the tank is very high even after cleaning. Is that normal?

In Al Quzayn salty humidity never drops, and the tank exterior stays damp even on dry days. This is normal in coastal zones but demands more frequent maintenance than inland neighbourhoods.

Is water from our tank safe to drink with all this salt in the air?

Salt on the walls does not enter the water in dangerous amounts if the tank is well sealed, but regular cleaning is essential in Al Quzayn to keep water quality safe.

The tank has reddish deposits on the walls that do not wash off easily. What is the remedy?

The red residue is iron oxide bonded with salt, and needs stiff brushing and special chemical cleaners to remove completely. Tank cleaning in Al Quzayn is harder work than in inland districts.

When is the best time to clean the tank in Al Quzayn?

Spring and autumn are best because humidity is slightly lower and the tank dries faster after cleaning. Summer and winter humidity runs so high that cleaning takes much longer to complete.

How much does water tank cleaning in Al Quzayn 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 Quzayn.
