Why the job is different in Al Rawdah

Upmarket villas have irrigated gardens and air conditioning that consumes water heavily, while nearby residential blocks use less. The imbalance in demand affects water quality in shared tanks. The method is set out in full on how we approach Water tank cleaning.

The first reason

Garden irrigation causes sudden heavy demand spikes

Luxury villas have large gardens and automated watering systems that consume large water volumes at set times. Rapid demand changes stir floor sediment and destabilise the settled layer.

The second reason

Mixed demand between villas and apartment blocks

A single tank may serve both luxury villas and residential blocks, creating large consumption swings between properties. Pressure fluctuations break up sediment layers and cloud the water.

The third reason

Cooling and humidity systems draw additional water

Upmarket villas have central air systems and humidifiers that use water for misting. This extra consumption affects salt and sediment ratios in the tank and alters water chemistry.

Before treatment

The condition of the tank decides the method

A central northern district on Madinah Road, with spacious upmarket villas and modern apartment buildings, commercial streets and public parks.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is grey from fine sand and sediment, easily stirred by pressure swings, needing regular maintenance cleaning.

Light and algae

Green algae grows moderately because modern tanks are shaded, but darkness and reduced light favour bacterial growth instead.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits are white or grey salt and fine sand, easy to remove but return quickly as consumption fluctuates.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are rare in modern tanks but pressure spikes may initiate small ones.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and access door are usually well maintained, though slow seeps from pipe joints can occur.

The vent and the overflow pipe

The vent opening is typically sound in modern tanks, though the overflow pipe may be narrower than ideal.

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 Rawdah

Mixed district: shops at street level with homes above them

Ground floor shops beside the villas increase water movement and consumption, and may leave traces from drainage systems that affect sediment patterns in shared tanks.

Questions about this district

Why does water cloud when irrigation starts at dawn?

Morning watering draws large volumes suddenly, raising pressure on the tank floor and re-suspending sediment and fine particles.

Should villas and flats have separate tanks?

Ideally yes, but if they share one, a larger tank and more frequent cleaning are needed to handle the consumption swings.

Do air conditioning and humidity systems pollute the tank?

Not directly, but they consume extra water. In a small tank, this raises salt and sediment ratios.

How often should shared tanks be cleaned?

Every two to three months, because consumption swings constantly stir the floor layer.

Does water run out faster in summer?

Yes. Watering and cooling increase consumption sharply in summer, and tank levels may drop very quickly.

Does Al Rawdah Park affect the tank nearby?

The park may shelter small insects but large trees reduce dust settling around the area slightly.

How much does water tank cleaning in Al Rawdah 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 Rawdah.
