Tank leak repair in Harat Al Amir Jeddah

Harat Al Amir is a small residential quarter inside Thuwal town, with small and old tanks scattered across rooftops and rear courtyards. Slow leaks are common because metal tanks corroded by salt and heat, and old pipes are cracked. We close the float valve and outlet together, then watch the water level to pinpoint the exact source of loss.

  • 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 Harat Al Amir

Most tanks here are old metal or simple concrete, many dating back more than twenty years. The method is set out in full on Tank leak repair in detail.

The first reason

Metal tanks corroded by salt

Metal tanks in the quarter suffer rust and corrosion from Thuwal's proximity to the Red Sea and salt in the air. Rust starts inside and outside together, creating tiny holes that leak slowly.

The second reason

Old pipes and broken connections

Tank inlet and outlet pipes are very old and metal fittings have corroded or cracked. Many leaks occur at the join between pipe and tank.

The third reason

Small tanks and difficult monitoring

Tanks here are small and roofs are tight, making them hard to reach and inspect. Families only notice the leak when they see the water bill or damp appearing on walls.

The character of Harat Al Amir

Mixed district: shops at street level with homes above them

Harat Al Amir is a small quarter with low buildings and small tanks, meaning repair work requires precision in tight spaces and limited rooflines. Treatment must account for old fittings and narrow connections.

Before treatment

Where the water leaves decides how it is repaired

A small residential quarter in the centre of Thuwal town near the municipality building, mosque and schools serving the whole town, with low buildings and small shops lining inner streets.

A concrete wall marked with damp and a white salt bloom

Damp and salt on the outside wall

Metal tanks leak from rust and holes caused by corrosion, especially in areas near the sea.

A fine crack running across a concrete surface

The kind of crack

The pipe inlet or connection between pipe and tank is a very common leak point due to wear and corrosion.

The corner where a concrete floor meets a wall

The wall to floor junction

The float valve and drain valve need checking as they may leak or fail to seal properly.

Water pipes passing through a concrete wall

Pipe entries

Small cracks in concrete tanks widen with heat and drying, so continuous monitoring is needed.

A blistered and peeling layer on a concrete surface

The condition of the old lining

Tank floor may collect sand and sediment that blocks the outlet or causes leaks from below.

What the tank is made of

Slow leaks cause dampness beneath the tank and wet ground around the roof, an early warning sign.

How we work

  1. 1

    Inspect and locate the leak

    We close the float valve and the outlet, mark the water level and watch it fall, then check the fittings and the wall beside it. That separates a tank leak from a pipe leak or a float valve that never shuts.

  2. 2

    Drain, clean and dry

    We empty the tank, lift the sediment off the base, wash back to sound concrete and let the surface dry. No repair holds on a damp or dusty face.

  3. 3

    Repair the cracks and the entries

    We cut the crack open, fill it with a non-shrink mortar, inject anything still weeping and rebuild around the pipe sleeve. A joint that moves takes a flexible detail, not a rigid one.

  4. 4

    Refill, test, then sterilise

    We refill, read the level again to confirm the drop has stopped, then sterilise before the water is used, because the tank has been open with tools and hands inside it.

What tank leak repair includes

  • A technician inspecting with a flashlight

    A marked level test

    A reading before and after with everything shut, which establishes that the loss is the tank and not the plumbing.

  • A metal floor drain

    Draining and sediment removal

    Water and silt out of the base, so the floor and the walls can be seen as they really are.

  • A spray nozzle in close detail

    Pressure wash and dry back

    The weak layer and the dust come off, because a repair only holds on sound concrete.

  • A gloved hand applying bait into a joint

    Cracks opened and filled

    The crack is cut open and filled with a non-shrink mortar, and anything still weeping under water pressure is injected.

  • The visit report being written on a clipboard

    Refill and a recorded test

    We refill, read the level again and write the reading down, so the result is not a matter of opinion.

  • A clean kitchen counter after treatment

    Sterilised and back in service

    A wash and a sterilisation once the material has cured, and guidance on running the first fill off before the water is used.

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

How do I know if the leak is the tank itself and not the pipes?

We close both the float valve and outlet together and watch the water level. If it drops, the leak is in the tank. If the level stays steady, the leak is in the pipes.

Does salt corrosion mean I must replace the whole tank?

Not always. If corrosion is surface-level and the leak is from one spot, we repair that spot and seal it. If corrosion is deep and widespread, replacement may be needed.

Do concrete tanks leak less than metal ones?

Concrete is stronger against corrosion but leaks through cracks and pores. Metal leaks from rust. Each type has different problems.

Is draining and cleaning the tank necessary before repair?

Yes. We drain all water and sediment, clean and dry the tank completely before repair. The repair surface must be clean and dry.

After repair, do you coat the tank with a protective layer?

Yes. After repairing the crack or pipe entry, we apply a protective layer against future rust and leaks.

How long does it take to repair a small tank like the ones here?

Usually between four and six hours from draining to drying to repair and sealing. It depends on the leak size and tank volume.

How much does tank leak repair 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.
