Water tank sterilization in Al Ghazzah Al Jadid Makkah

Al Ghazzah Al Jadid is a new quarter developing along Al Laith Road south west of Jeddah, now filling with villas, apartment buildings and retail shops. Tanks here are newly installed but require periodic sterilization because water leaves sediment quickly and new pipelines may retain construction debris. Tank sterilization ensures clean water from the first day in a new home.

  • 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 Ghazzah Al Jadid

The zone is entirely new with buildings and villas still under construction and initial occupation, and tank installations are recent with the projects themselves. The method is set out in full on Water tank sterilization in detail.

The first reason

New tanks and fresh pipework

Metal tanks are newly fitted and may not have been properly washed before use. New copper and steel pipes may retain rust flakes and debris from installation and first-fill testing.

The second reason

Rapid sediment buildup in raw water

Al Laith water quality is not high, and sediment accumulates fast in new tanks. Sterilization requires complete removal of the bottom layer before agent application.

The third reason

High demand for pre-occupancy sterilization

Families moving to new villas and apartment blocks request tank sterilization before moving in. Finish-out and occupancy season peaks in autumn and winter.

The character of Al Ghazzah Al Jadid

New development: ongoing construction and vacant plots between the homes

Al Ghazzah Al Jadid is a fast-developing zone where tanks are newly installed and pipework has not yet been in service long. Sterilization here focuses on removing installation and testing debris more than cleaning heavy sediment layers.

Before treatment

What we read inside the tank before anything starts

A new development zone on Al Laith Road near the junction of the Fourth Ring Road and Al Laith, west of Al Ukayshiyah, with Ahmad Al Barqi Street as the main spine and plots zoned for shops and housing.

Fine wet sand seen close up

Sediment on the floor

Inspection of the tank exterior reveals installation marks and surface rust on fresh metalwork.

A concrete wall carrying a damp green layer

The slime film on the wall

Inspection of the first and last taps shows whether pipework still holds debris from installation.

A plastic water tank standing on a rooftop

Light and heat

Inspection of the tank floor after emptying reveals white and grey sediment and oxidation from water and pipes.

A concrete surface carrying fine cracks

The lining and any cracking

Moisture inside a new tank is high from standing water and first wash, so ventilation is essential after sterilization.

A metal cover over a water tank opening

The lid and the openings

Bacteria and algae are rare in very new tanks but may form in corners and gaps during testing phases.

What shows up at the tap

Chlorine smell persists for hours after sterilization, and full flushing from the furthest tap removes it completely.

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 Makkah Sub-Municipality

South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.

Questions about this district

Does a brand new tank need sterilization?

A new tank may look clean outside but pipework and fittings leave debris and oxidation. Initial sterilization removes everything left by installation and first testing.

When should I sterilize the tank after moving in?

Best before or during the first week of occupancy. Sediment starts building from day one, and delay means harder removal of the bottom layer.

Does Al Laith water need different treatment?

Al Laith water carries more sediment than other sources. Sterilization requires stronger wall and floor washing.

What if the tank is new but water has turned cloudy?

Cloudiness comes from sediment and oxidation in new pipework. Sterilization must include opening the furthest tap and flushing all lines fully.

Is one sterilization enough for a new tank?

One proper sterilization is enough if done correctly. After that routine cleaning every six months to a year maintains it.

Does a new tank take a long time to sterilize?

New tanks are faster because sediment is light. Sterilization takes three to four hours including emptying, washing and application.

How much does water tank sterilization in Al Ghazzah Al Jadid 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 Ghazzah Al Jadid.
