Water tank cleaning in Wali Al Ahd Makkah

Wali Al Ahd is a new scheme being built gradually south of Al Shawqiyah within the Haram boundary. Three storey apartment blocks sit among residential plots still being built, and new schemes are activated in stages. Your tank endures constant pressure swings from phased construction and absorbs dust from ongoing excavations and building work across the neighbourhood.

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.

Why the job is different in Wali Al Ahd

Tanks here suffer from variable pressure caused by ongoing construction, and dust from excavation and fill operations enters tanks easily. The method is set out in full on what Water tank cleaning involves.

The first reason

Phased building creates uneven pressure on the network

The scheme builds plot by plot and construction never stops, so pressure on the water system changes constantly. Tanks in completed sections face very high pressure then sudden drops when new building phases begin nearby.

The second reason

Excavation and fill operations kick up dust clouds

Continuous digging and building work raise waves of fine dust and soil particles. Tanks absorb this dust with every new construction phase starting around the scheme.

The third reason

New pipes may carry building contaminants in the water

Newly installed pipes may hold cement dust and building debris inside, and this enters the tank when water first flows through. Flushing new pipes before connecting to the supply is essential.

Before treatment

The condition of the tank decides the method

Wali Al Ahd is a newly developing scheme south of Al Shawqiyah on residential land still under construction, with mid rise apartment buildings and surrounding building activity.

Fine brown sediment beneath shallow water

The layer on the floor

The floor accumulates fine dust from ongoing excavations and construction, and cement particles from newly installed pipes.

Light and algae

Light and algae may appear in exposed tanks due to the unstable environment and airborne dust.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits build from dust and cement debris from the continuous building activity around the tank.

A concrete surface with a fine hairline crack

The lining and hairline cracks

The new plastic lining may crack from variable pressure caused by phased construction.

The lid and the access hatch

The lid and access hatches collect dust and soil from excavations and building work nearby.

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.

What is different about Al Shawqiyah Sub-Municipality

Al Shawqiyah sub municipality runs south from the Third Ring Road to the city's edge on the Al Layth road and the Jeddah expressway. Planned districts such as Al Shawqiyah, Al Malik Fahd and Bathaa Quraish have wide streets, villas and apartment blocks, while schemes in Wali Al Ahd are being built out and informal housing in Al Ukayshiyah and Al Zuhur is being cleared. The vegetable market and livestock auction at Souq Al Halaqa, open construction sites, the rocky slopes of Jabal Thawr and sewers still being laid through the southern fringe offer exposed food, shelter and moisture.

Questions about this district

Why does water discolour so fast in a developing scheme?

Dust from excavations and building enters the tank easily, and changing pressure causes disturbance in the water. Ongoing construction means continuous changes in water quality.

Can new pipes carry building material into the supply?

Yes, newly installed pipes may hold dust and cement debris from construction. Flushing both pipes and tank together is essential at the start.

Do we need more frequent cleaning because of ongoing construction?

Yes, active building means constant dust and variable pressure. Cleaning needs to be more frequent than in settled neighbourhoods.

Does constant pressure change cause tank cracks?

It may place stress on the tank and pipes. Regular inspection for leaks and cracks is needed.

When will building and development finally finish in this scheme?

The scheme will develop over several years. Until building ends, regular cleaning is necessary.

Is there a safe period for use while building is ongoing?

Regular cleaning and inspection keep water safe even during construction, but caution is needed.

How much does water tank cleaning in Wali Al Ahd 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 Wali Al Ahd.
