Water tank cleaning in Al Wurud Jeddah

Al Wurud is a residential district between King Fahd Road and Prince Majid Road, mixing villas with mixed residential and commercial apartment blocks. The district grew on the site of Jeddah's old airport, which means the soil beneath it is unusual and may affect water tanks, especially where shallow foundations from the original construction remain.

Why the job is different in Al Wurud

Al Wurud tanks show sediment related to the inherited soil character from the old airport site, and may contain unusual metal particles from cement and old metal debris left behind. The method is set out in full on Water tank cleaning in detail.

The first reason

Old airport ground leaves unusual traces

Al Wurud stands on old airport land, and soil under tanks may contain heavy metals and broken cement from the original buildings. These particles may enter the tank through soil seepage around foundations.

The second reason

Shallow foundations from the old buildings remain unstable

Tanks on old airport foundations may sit on unstable bases. This can cause tank vibration and small cracks that allow soil particles to enter, introducing contamination not seen in standard neighbourhoods.

The third reason

Unusually high moisture persists around the old site

Soil at the old airport site may retain moisture because old concrete layers below obstruct drainage. This makes humidity around Al Wurud tanks higher than in other neighbourhoods.

Before treatment

The condition of the tank decides the method

The district sits on relatively flat ground but with a different history beneath: soil moisture patterns differ from normal ground, and the water table near tanks may be higher because earth from the old airport retains moisture differently.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in Al Wurud tanks contains heavy metal particles and old cement from the airport site, not standard metal deposits like other areas.

Light and algae

Light and algae grow at moderate rates, but high moisture from the soil may encourage unusual coloured algae species.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls hold both white and dark layers of salt and heavy metal deposits, more difficult to remove than standard sediment.

The lining and hairline cracks

Linings may be damaged by vibration and cracks from unstable base movement, and may need replacement rather than repair.

Tank lids and access hatches may be stuck from old cement and debris, opening may need extra force.

The vent and the overflow pipe

Vent holes and overflow pipes may contain heavy metal particles and old cement and need very thorough cleaning beyond standard screening.

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.

The character of Al Wurud

Mixed district: shops at street level with homes above them

In Al Wurud on the old airport site, the tank faces unusual stresses from a weak foundation and anomalous soil, so cleaning must account for heavy metal particles and old cement not found in standard residential neighbourhoods.

Questions about this district

Does old airport ground affect water quality?

Yes, soil may contain heavy metals and old cement, some of which seep into the tank. Regular cleaning helps but you may need an additional filter.

The tank seems to shift slightly. Is that dangerous?

Yes, weak foundations can cause vibration and the tank may shift slowly over time. This causes cracks and leaks. Engineering inspection is needed and the base may need reinforcement.

Humidity around the tank stays high even in summer. Why?

Soil at the old airport site retains moisture because concrete layers below block drainage. You may need an improved drainage system around the tank base.

Water smells like soil and chemicals mixed. What causes this?

May be heavy metal particles from old soil entering through seepage, or soil bacteria. Full cleaning and disinfection help.

Do Al Wurud tanks need regular engineering inspection?

Yes, the unusual site demands regular inspection of the base, cracks and leaks. Annual inspection at minimum is necessary for safety assurance.

Does tank cleaning improve the chemical and soil smell?

Good cleaning helps, but if the smell comes from the soil itself you may need a carbon filter on the outlet or additional water treatment.

How much does water tank cleaning in Al Wurud 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 Wurud.
