Water tank sterilization in Shaab Ali Al Jadid Makkah

Shaab Ali Al Jadid is a new development scheme south of Jeddah with new villas whose tanks have either never been used or were only recently filled. The water here is clean but new tanks need initial sterilization before regular service begins. Wadi Uranah crosses the district and the Fifth Ring Road marks its boundary.

    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 Shaab Ali Al Jadid

Most villas were built in recent years and their tanks are new or nearly new, with water supplied from the municipal network that is relatively clean. The method is set out in full on Water tank sterilization in detail.

The first reason

New tanks never used or used only recently

Most new villas here have tanks that have not yet entered service or have been used only for weeks. New tanks need initial sterilization before full operation and regular supply begins.

The second reason

Municipal water is clean but tanks need protection

The municipal water here is clean but new tanks may retain manufacturing dust from production and transport. Internal lines may need initial flushing and sterilization protects the water from contamination in the reservoir itself.

The third reason

Individual villas require independent tank maintenance from the start

Villas are dispersed across the scheme and owners are responsible for tank maintenance individually. Initial sterilization establishes correct maintenance habits from day one.

What we read inside the tank before anything starts

A modern residential development scheme south-west of Jeddah with new villas and registered plots, bounded by Al Falaq Al Jadid on one side and Shaab Amer Al Jadid on the other.

Fine wet sand seen close up

Sediment on the floor

Sediment in new tank floors is white or grey dust from manufacturing and transport, removed entirely by mechanical lift and pressure wash.

A concrete wall carrying a damp green layer

The slime film on the wall

Biofilm has not yet formed in new tanks but modern tank walls may retain fine layers of oils and dust requiring high-pressure washing.

Light and heat

Water lines from tank to the furthest taps in the villa may contain air and pipe debris from installation; flushing removes these.

A concrete surface carrying fine cracks

The lining and any cracking

Moisture inside the tank after washing requires control: sterilization is applied to clean, relatively dry walls before the tank is filled.

Nesting sites do not exist in new tanks because they have never been in service, but walls may have weak points from manufacturing.

Seasonal activity is irrelevant here as tanks are new and owner control begins from day one.

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 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.

Questions about this district

Does a new tank need sterilization if it has never been used?

Yes. New tanks may retain manufacturing dust and dust from transport and storage. Initial sterilization cleans the internal surface and protects the water from contamination.

Does clean municipal water eliminate the need for sterilization?

Municipal water is clean but the tank itself may introduce contaminants. Sterilization ensures the tank does not compromise the water quality.

How often should a new tank be sterilized in its first year?

Initial sterilization before regular service is sufficient. After that, routine maintenance every six months or based on water quality.

Do algae and bacteria grow in new tanks?

Yes if the tank is left uncovered or in direct sunlight. Initial sterilization removes any bacterial spores present from manufacturing.

Does sterilization kill everything in the tank or does it leave protective residue?

Sterilization kills current contaminants then leaves trace disinfectant to protect the water for a period. Final flushing removes sediment.

Does the length of water lines in the villa affect sterilization coverage?

Yes. Longer lines need more flushing to ensure the disinfectant reaches the furthest tap in the house.

How much does water tank sterilization in Shaab Ali 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 Shaab Ali Al Jadid.
