Water tank cleaning in Al Qararah Al Jadid Makkah

Al Qararah Al Jadid is a new scheme south of Makkah within the Crown Prince developments, granted residential plots and scattered new villas on flat open ground. Tanks here face unique challenges: bare earth raises dust and moisture, Wadi Uranah carries flash floods after rain, scattered building means ongoing dust entry, and new tanks may sit deep and be hard to access. Each clean reveals what the next bare patch will bring.

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 Qararah Al Jadid

Tanks fill quickly from strong new networks but water carries dust and earth from excavation and bare ground, since there is no vegetation to hold the soil or reduce wind blown dust. The method is set out in full on our Water tank cleaning service.

The first reason

Bare earth and dust and high moisture

Wide vacant plots without plant cover release dust easily on wind, and moisture from flood water stays in low ground around tanks. Tanks draw mould and damp from every direction in this open bare zone.

The second reason

Wadi Uranah and flash floods after rain

The wadi cuts through the scheme and carries floods after rain, water carries soil and silt and microbial growth from low ground and the wadi channel itself. Ground tanks risk seepage when the wadi fills and raises water pressure around the foundations.

The third reason

Deep tanks and scattered building and access

Some tanks are built deep for larger capacity, so cleaning needs special equipment and trained access. Scattered building means excavation continues, the tank risks damp and dust from an adjacent building site.

Before treatment

The condition of the tank decides the method

A new subdivision on flat open land, granted plots and scattered new villas, crossed by Wadi Uranah with hills around it, building incomplete and networks still under development.

Fine brown sediment beneath shallow water

The layer on the floor

The floor is light fine earth and gravel from excavation and bare ground, needing high pressure and firm brushing to clear completely before it hardens and bonds to the lining.

Light and algae

Light and algae are low in new sealed tanks, but high moisture from surrounding bare ground encourages fungi in vent openings and screened sections.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls carry a light film of fine cohesive earth that needs warm water and circular brushing to remove without scratching the fresh concrete surface beneath.

A concrete surface with a fine hairline crack

The lining and hairline cracks

New concrete absorbs disinfectant easily, and hairline cracks from rapid drying in hot weather trap bacteria, so deep penetration of the disinfectant is essential for lasting protection.

The lid and the access hatch

The cover seals well and is new, but we check for moisture buildup under the rim and remove any dew or light mould on surfaces in this high humidity zone.

The vent and the overflow pipe

Vent and overflow are critical because pressure rises from moisture and wadi flood risk, so we open both fully during cleaning and ensure the overflow pipe runs clear of earth and silt.

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 Al Jadid

New development: ongoing construction and vacant plots between the homes

In a newly built scheme, the new tank faces pressure from ongoing construction and bare exposed ground: dust, earth, moisture and flash floods. Cleaning here needs more frequent cycles than in finished, settled districts.

Questions about this district

The tank is new but the water is cloudy with dust and earth. How do we prevent this?

Dust enters from air and excavation around you. First cleaning is essential, and protecting vent openings with clean screens stops most dust entry from wind.

After heavy rain the water is very cloudy and smells of silt. Normal?

Yes. Floods carry soil and silt into the network. Wait one week after heavy rain then clean the tank, you may need a second clean to clear until water stabilises.

Should we clean the tank before or after seasonal rain?

Clean one month before seasonal rain, then again two weeks after heavy downpours. The scheme needs frequent cleaning because dust and floods are ongoing.

The whole district water is cloudy at the same time after rain. Is it the shared tank?

If there is a communal tank, yes. If tanks are separate, cloudiness comes from floods entering the distribution network everywhere at once. Cleaning the tank and pipework together is essential.

The tank is very deep. How do we clean it safely without falling risk?

Deep tanks need specialist equipment and trained teams. Never enter a deep tank without ventilation and safety gear, always use professional contractors with full safety equipment.

Are new tanks strong enough to take high pressure cleaning?

Yes, new tanks are very strong. But pressure must match wall thickness, using excessive pressure on thin walls can damage them.

How much does water tank cleaning in Al Qararah Al Jadid 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 Al Jadid.
