Water tank sterilization in Al Quzayn Jeddah

Al Quzayn is the southernmost coastal strip of Jeddah, beginning as a small fishing village and developing into a quiet seaside resort. Coastal villas, rest houses and small resorts line an open beach. Tanks here sit very close to the sea and salt-laden humidity corrodes metal fixtures and pipes. Sterilization requires special care for rust and salt deposits left by the sea air.

  • Potable-rated materials

    Linings and disinfectants cleared for drinking water tanks, not general-purpose products.

  • 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.

  • Ground and roof tanks

    Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Al Quzayn

Villas and cottages sit very close to the sea and salt humidity is very high. Small resorts and marine reserves lie close to the sewage treatment works and an iron factory. The method is set out in full on our Water tank sterilization service.

The first reason

Salt humidity and rapid rust

Salt-laden sea air is constant and causes rapid rust on pipes and metal tanks. Salt deposits coat interior walls in thick layers of mineral residue and moisture.

The second reason

Villas and small resorts with individual tanks

Coastal villas and small resorts have old private tanks. Tanks hold marine algae, salt deposits and minerals from sea air.

The third reason

Treatment plant and factory affect water and the environment

A sewage treatment works and iron factory stand very close to homes. Water may carry traces of environmental pollutants and may need stronger disinfection.

The character of Al Quzayn

Coastal area: high humidity and salt air through the year

The coastal location means tanks are constantly exposed to salt humidity and mineral deposits. Rapid rust and salt accumulation need very deep mechanical cleaning, and sterilization must be stronger than in inland areas.

Before treatment

What we read inside the tank before anything starts

The southernmost coastal strip in south Jeddah on the Southern Corniche, began as a small fishing village. King Faisal Road bounds it to the north and Southern Corniche Street runs along its western shore directly by the sea.

Fine wet sand seen close up

Sediment on the floor

Salt deposits from sea air coat tank walls and pipes in thick layers requiring very deep cleaning.

A concrete wall carrying a damp green layer

The slime film on the wall

Marine algae and seawater bacteria grow rapidly in old tanks with very high humidity.

Light and heat

Line flushing needs special care because pipes may be heavily rusted and water may carry rust and salt particles.

A concrete surface carrying fine cracks

The lining and any cracking

Salt humidity is very high and sea breezes keep temperatures moderate, promoting marine algae and bacteria growth.

The lid and the openings

Bacterial colonies form on the tank floor around salt deposits and mineral sediment, with marine algal layers on walls.

How we work

  1. 1

    Inspect and record the condition

    We open the hatch and work through what the tank is made of and how big it is, how deep the sediment lies, the state of the lining, whether the lid and the overflow seal, and whether there is a crack that has to be repaired before any sterilizing.

  2. 2

    Drain and lift the sediment out

    The water goes out, then the silt and sand are lifted off the floor by suction rather than pushed toward the outlet, because pushing them sends them into the house pipework and the heater.

  3. 3

    High pressure wash

    Walls, floor, corners and the area around the outlet, until the slime film is completely gone. This is the step that makes the sterilizing after it mean anything.

  4. 4

    Sterilize, rinse, then return to service

    The sterilizing agent goes onto the walls, the floor and the underside of the lid and is left for its contact time, then we rinse, refill and run the furthest tap until the whole line is clear.

What water tank sterilization includes

  • A technician inspecting with a flashlight

    A recorded inspection

    Material, capacity, sediment depth, the state of the lining, the lid and the overflow, all before any work begins.

  • A metal floor drain

    Draining and sediment removal

    The water out, and the silt and sand lifted off the floor instead of being pushed into the outlet and the house pipework.

  • A spray nozzle in close detail

    High pressure washing

    Walls, corners and around the outlet, until the biofilm that no disinfectant penetrates has gone.

  • A spray nozzle in close detail

    Sterilizing the internal surfaces

    A sterilizing agent meant for drinking water tanks, applied to the walls, the floor and the underside of the lid, and left for its contact time.

  • A clean kitchen counter after treatment

    Line flush and aftercare

    Rinse, refill and a flush from the furthest tap, when the water is usable again, and what to change in the filter afterwards.

  • The visit report being written on a clipboard

    The next cycle

    We agree the right interval for your tank from how it is filled, how much sun it takes and the condition of the lid.

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

Why do tanks in Al Quzayn rust so quickly?

Salt-laden sea air causes very rapid rust on metal. Salt deposits on inner and outer surfaces accelerate metal decay.

Does sterilization protect the tank from future rust?

No. Sterilization only disinfects water. Tank protection from rust requires protective coating or replacement with salt-resistant tanks.

Do salt deposits from sea air reduce disinfectant strength?

Yes. Salts may slightly weaken the disinfectant. Deep cleaning must remove all salt deposits before disinfection.

Is water safe to drink after sterilization despite the plant and factory nearby?

Yes. After deep cleaning, complete disinfection and line flushing, water is safe. Additional tests may be needed if environmental pollution is evident.

Do coastal villas need special tank treatment?

Yes. Small villa tanks get dirty quickly and need more frequent sterilization than standard homes and large tanks.

How does the treatment plant affect water quality in Al Quzayn?

The plant may introduce environmental pollutant traces in water and air. Disinfection should be slightly stronger than in areas far from the plant.

How much does water tank sterilization 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.
