Water tank cleaning in Al Falaq Al Jadid, Makkah

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 Falaq Al Jadid

Tanks here are new but surrounded by deep foundation trenches and damp soil. Ground water may rise sharply after heavy rain and cause problems in tanks. The method is set out in full on what Water tank cleaning involves.

The first reason

Wadis, flooding and water held by low ground after rain

Wadi Uranah crosses the area and its tributaries carry floods. Low ground holds water for days after rain. Continuous damp raises the water table sharply around tanks.

The second reason

Deep excavation pits and ongoing building work near tanks

Deep foundation trenches surround tanks. Ongoing construction changes the path of underground water. The tank may shift slightly as new trenches are dug.

The third reason

Surrounding hills that direct water towards low ground and tanks

Jabal Aghzul and surrounding hills channel water towards the low points and tanks. Water from the hills collects at certain points and may seep into tanks from the side or below.

Landmarks of Al Falaq Al Jadid

Our teams reach tanks via the Fifth Ring Road from north or south, and tanks are located among new villas and apartment blocks below Jabal Aghzul which marks the project boundary.

Before treatment

The condition of the tank decides the method

A newly developed district on open ground south of the city with construction projects and large vacant plots, a wadi running through it that holds water after rain.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is dark sandy and wet from ground water and flood silt. Removal requires care because sediment clings under continuous moisture.

Light and algae

Algae, fungi and black mould grow fast from continuous high humidity. Ground water carries bacteria that speed fungal growth.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall coating is grey from sandy sediment and mould together. Cleaning needs special technique to clear deep fungal growth.

A concrete surface with a fine hairline crack

The lining and hairline cracks

New lining may crack from water pressure from below or from soil movement caused by nearby deep trenches.

The lid of a water tank on a building roof

The lid and the access hatch

Lids and openings are new but may leak from water pressure from below. Mould may appear on metal parts quickly.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Air vents and overflow pipe may clog with sandy sediment and mould. Insects and rodents from building pits may enter through unguarded openings.

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 South Makkah Sub-Municipality

South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.

Questions about this district

Is water leaking from the tank side caused by ground water or building excavation?

It may come from rising ground water or water flow from the hills. Deep trenches change the path of water and increase leaks.

Does ongoing construction on the project affect existing tanks?

Yes. Excavation and building change the path of ground and surface water. Existing tanks may experience higher than expected water pressure.

Do nearby wadis cause flooding that reaches the tank directly?

Floods may come close to the tank depending on its location. Indirect seepage through the water table is a bigger risk.

Do new tanks need extra protection from dampness and ground water?

Yes. New tanks in damp areas need strong external sealing and geological study before installation.

Can rodents and reptiles living in building pits enter the tank easily?

Open building trenches shelter rodents and reptiles. Nearby tanks may be at risk if not well protected.

How often must a tank in a new scheme like this with wadis and flooding be cleaned?

Tanks here need cleaning at least every two months. After major flooding an urgent inspection and cleaning if needed.

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