Why the job is different in Al Qararah Wa Al Naqa

Tanks here experience extreme pressure swings, cut off entirely during Hajj peaks then suddenly flooded when pressure rises, causing leaks and rupture cycles that rarely occur in areas with steady network pressure. The method is set out in full on our Water tank cleaning service.

The first reason

Modern polyethylene tanks beside old cement tanks on the same street

New villas in Al Qararah have brand new polyethylene tanks while old houses next door have corroded cement tanks coated in rust. This means two entirely different cleaning protocols operate within the same area: new tanks require gentle washing, old tanks demand scraping and deep disinfection.

The second reason

Pressure swings from the Grand Mosque network immediately adjacent

Tanks here sit almost directly on the Grand Mosque network lines, so during Hajj water cuts off entirely, then surges back when demand drops. This pulsing pressure fractures tank linings and makes thorough cleaning far harder than in areas with steady supply.

The third reason

Unstable ground and broken pipes from ongoing redevelopment work

The Rua Al Haram project and construction surrounding Al Qararah mean continuous excavation near tanks. This fractures inlet and distribution pipes, allowing sand from building sites and excavation dust to mix with water before it reaches the tank.

Before treatment

The condition of the tank decides the method

Al Qararah Wa Al Naqa lies directly east of the Grand Mosque where the Al Masjid Al Haram Road climbs toward Al Mualla, with land split between old structures, ongoing development work and excavation sites operated by contractors.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in old Al Qararah tanks is thick and hard, but new tanks may be completely sediment free in early months, then accumulation begins as the water ages.

Light and algae

Light and algae are not an issue in sealed tanks, but bacteria can multiply rapidly in warm summer water, especially after repeated pressure drops and outages.

The deposit on the wall

Old tank walls are rusty and coated with thick silt, while new walls are clean white or grey when first filled.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings in old tanks crack from pressure swings, and new tanks may leak at joint connections if not professionally installed.

The lid and the access hatch

Access lids and hatches in new villas seal very tightly, but old houses near the mosque may have loose or broken openings.

The vent and the overflow pipe

Ventilation openings in new areas may be missing or incorrectly installed, allowing air and moisture to trap inside the tank.

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 Qararah Wa Al Naqa

New development: ongoing construction and vacant plots between the homes

New development means some tanks are in early service and benefit from preventative cleaning before problems surface, especially where excavation is dragging building dust into the network. Early cleaning prevents construction sediment becoming a permanent layer later on.

Questions about this district

Water cuts off completely during Hajj then returns very cloudy, why is this?

Complete cutoff means the tank empties and air enters the pipes. When pressure returns, water drags everything accumulated inside the pipework into the tank. Cleaning before Hajj and safe tank drainage reduces this effect significantly.

Does the excavation and building work around the villa affect water purity?

Yes, very significantly. Digging can crush or crack distribution pipes, and dust and sand from building sites enter the network everywhere. Repeated cleaning may be necessary until construction finishes around the house.

Does the brand new tank in our new villa need cleaning after just one month?

This may be normal if construction work is still ongoing around the villa. New pipes can drag initial building dust. Once construction finishes around the site, cleaning frequency will reduce substantially.

Should we arrange extra tank cleaning just before Hajj in Al Qararah Wa Al Naqa?

Yes, strongly recommended. Hajj pressure is extreme and will empty tanks and may create vacuum. Cleaning and disinfecting two weeks before ensures clear water throughout the season.

Our brand new tank water smells of plastic, is this normal?

New polyethylene tanks may release a plastic odour in the first weeks. Full cleaning, good ventilation, disinfection and then running water through several times removes this completely.

Is cleaning a new tank completely different from cleaning an old one?

Yes, completely. New tanks are sensitive to scratching and need specialist cleaners, while old tanks need strong scraping and deep disinfection. Each type has its own protocol.

How much does water tank cleaning in Al Qararah Wa Al Naqa 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 Qararah Wa Al Naqa.
