Why the job is different in Al Malik Fahd

Mixed-use tanks need different care because pressure and consumption shift hour by hour between shops and residents, and deposits form in uneven patterns rather than settling uniformly. The method is set out in full on the full Water tank cleaning page.

The first reason

Shops and homes with variable water pressure

The tank serves retail, restaurants and flats, with consumption varying throughout the day. Pressure rises at night and drops during peak hours when shops operate, causing rapid sediment formation in certain tank zones and uneven distribution of suspended particles. The settled layer at the floor keeps lifting and resettling as pressure changes.

The second reason

Prince Nayef Road and underground pipes

Pipes run beneath Prince Nayef bin Abdulaziz Road and the Fourth Ring Road. Heavy traffic vibration and road construction cause small cracks and seepage in the lines. This affects incoming water clarity and allows dirt and particles to enter the tank from fractures in aged pipe work beneath the street.

The third reason

Jabal Umm Jurfan and elevated terrain

The district borders a rocky hill and sits on relatively high ground, altering how water distributes and pressure builds inside the tank. The elevation changes how sediment settles and when groundwater mixes with tank water during seasonal shifts, introducing mineral-rich water that deposits quickly.

The character of Al Malik Fahd

Mixed district: shops at street level with homes above them

A mixed district means one tank serves shops, restaurants and homes together, making water consumption uneven and pressure rise and fall hour by hour. This accelerates sediment formation and complicates both cleaning and disinfection routines.

Before treatment

The condition of the tank decides the method

The district sits west of the city on the Jeddah expressway and Fourth Ring Road, bordered by the rocky Jabal Umm Jurfan. Pipes run beneath Prince Nayef bin Abdulaziz Road, complicating tank access and maintenance routes.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment builds faster and denser in tanks serving shops because high consumption constantly lifts particles from the floor, creating a thicker grey-brown layer than residential-only tanks.

Light and algae

Algae grow rapidly in mixed-use tanks because pressure, temperature and consumption fluctuate, creating unstable conditions where cells thrive. Sunlight reaches the water during low-use periods when pipes are not full, accelerating green growth.

The deposit on the wall

The wall deposit is a thick brown film of bacteria and minerals because water sits still at times and flows fast at others, causing particles to bind more firmly than in tanks with steady consumption.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks appear from constant pressure swings and vibrations from the nearby road. The lining endures pressure that varies throughout the day, stressing the concrete and weakening old lining edges.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and hatches need regular inspection for leaks from below because night pressure forces water out through overflow and drain openings. Seals that held tight at moderate pressure may weep when pressure rises.

The vent and the overflow pipe

Vent and overflow pipes need shielding from odours and insects attracted by food preparation smells from nearby shops and restaurants. Commercial cooking vapours travel down ventilation paths and draw pests to the tank area.

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

Why does water in the shops become cloudy faster than in the apartments?

Retail outlets and restaurants consume water in large sudden bursts, stirring up settled material from the tank floor. Intermittent consumption causes pressure swings that re-suspend particles in the water, making it persistently hazy during business hours.

Do underground pipes beneath the road contaminate the water?

Yes. Pipes running under Prince Nayef Road and the Fourth Ring Road face traffic vibration and excavation, creating hairline cracks and seepage. Water enters the tank carrying dirt and particles drawn from the soil beneath the street where pressure dips inside the old pipe.

How often must a tank serving a shop or restaurant in Al Malik Fahd be cleaned?

More often than apartment-only tanks, typically every two months because high consumption constantly lifts settled material from the floor. A tank serving retail should be cleaned before a tank serving flats alone.

Does rapid pressure change cause cracks in the tank?

Repeated fluctuations may speed the growth of existing hairline cracks but do not cause new fractures directly. However, older tanks in Al Malik Fahd may already be stressed from years of high consumption and need inspection.

Should shops below flats need stronger disinfection than plain residential water?

Yes. Shops and restaurants prepare food and drink, so disinfection must be more thorough and stronger. A shared tank must be treated as a commercial tank, not a domestic one, because one end serves food preparation.

Does high night pressure cause old tanks to leak from below?

Yes. Pressure rises at night when consumption is low, forcing water out through drainage and overflow openings. Older tanks in Al Malik Fahd may show active leaks from the lower hatch or pipe joints when pressure builds after hours.

How much does water tank cleaning in Al Malik Fahd 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 Malik Fahd.
