Water tank cleaning in Al Hamdaniyah Jeddah

Al Hamdaniyah is a dense mixed district east of King Abdulaziz Airport, with shops and apartment blocks spread along Al Hamdaniyah Street and Al Masurah Street, and hypermarkets on both roads. Tanks serve a wide mix of uses: large retail outlets and markets draw water continuously at high pressure, and seasonal wadis and airport drainage affect the local groundwater.

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 Hamdaniyah

Tanks here fill from mixed sources: local groundwater and the central network both feed the supply, and the groundwater carries higher salinity that deposits on walls and floors faster than piped water alone. The method is set out in full on how we approach Water tank cleaning.

The first reason

Large supermarkets draw water in bursts at high pressure

Big stores and markets pull vast quantities during trading hours, pressure drops suddenly, and sediment is mobilised and enters the mixed-use pipes. The pressure swing is much larger than in residential areas alone.

The second reason

Groundwater and piped supply mix in one tank

Al Hamdaniyah draws from two sources: local groundwater is mineral-heavy, the central network is cleaner. The mixing of high-salinity and low-salinity water increases precipitation and deposit formation.

The third reason

Airport and seasonal wadi drainage raise the water table

The airport and nearby seasonal wadis raise the local water table height. External groundwater pressure on the tank increases, forcing saline groundwater to seep into the tank through minor cracks.

The character of Al Hamdaniyah

Mixed district: shops at street level with homes above them

Mixed use means tanks serve heavy commercial demand and residential consumption simultaneously. Large retail stores draw water at pressures and flow rates very different from residential flats, and water mixed from different sources needs specialist cleaning protocols.

Before treatment

The condition of the tank decides the method

A dense commercial and residential spread east of the airport, with major supermarkets, wide streets, high groundwater, and the airport nearby raising ambient humidity through its drainage systems.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer collects red sand and clay from groundwater, thick and difficult to dislodge completely.

Light and algae

Algae grows rapidly in mineral-rich water, especially in tanks with roof exposure and light penetration.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall deposit is white and thick from calcium and magnesium salts crystallised from the groundwater.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks form from external groundwater pressure pushing on the tank shell from outside.

The lid and the access hatch

The lid and access hatch stay damp from groundwater seepage, so they need cleaning of moisture and mould.

The vent and the overflow pipe

The vent becomes clogged with moisture and mould from the damp conditions, and must be cleared from inside to restore air flow.

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.

Questions about this district

Does the shop water go cloudy after peak usage in the morning?

Large supermarkets pull huge flows fast, pressure collapses, and water heavy with sediment drops out of the pipes into the outlet.

Is the water saltier here than in flats on the same street?

Shops may draw from different groundwater sources than residential blocks. Local groundwater mineral content is very high, especially for shops on lower ground.

After seasonal rain, does the tank need extra cleaning?

Rain raises groundwater levels fast, so saline water enters the tank under higher pressure. Cleaning within a week of heavy rain is recommended to manage the spike in mineral load.

Are tanks in Al Hamdaniyah more likely to leak than in other districts?

Yes, high groundwater pressure pushes on tank walls from outside. Older tanks may develop seepage around the base or walls as external pressure overcomes the shell.

The water carries red sand from groundwater. Does it matter?

Sand and clay from groundwater settle on the floor. Regular cleaning removes it before it blocks pipes and restricts flow.

How many times a year should we clean a tank in Al Hamdaniyah?

Two to three times yearly, because salinity and groundwater mineral load deposit much faster than in districts with piped water alone.

How much does water tank cleaning in Al Hamdaniyah 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 Hamdaniyah.
