Water tank cleaning in Al Thaghr Jeddah

Al Thaghr is a mixed use district north of Old Makkah Road, holding villas, apartment blocks and the long established Al Thaghr Model Schools. Tanks here serve buildings of different ages and use types, and the ongoing development around the school and hospital raises dust and fresh sediment continuously. The work is not heavy but the cleaning interval must account for external particles.

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 Al Thaghr

Al Thaghr tanks accumulate light but steady sediment because residential use here is stable but dust from school development and the hospital constantly adds new particles to the water. The method is set out in full on what Water tank cleaning involves.

The first reason

Mixed building types carry variable loads

Al Thaghr holds detached villas and residential apartment blocks, and a tank may serve one block or a single villa. Usage is less irregular than in commercial mixed districts but more varied than purely residential areas elsewhere.

The second reason

Dust from school and hospital is constant

Al Thaghr Model Schools and the hospital draw heavy daily traffic, and ground around both is under development. Dust enters tank vents and access points regularly, and sediment must be removed on a set schedule.

The third reason

Location near major roads and expressways

Prince Majid Road, King Khalid Road and Old Makkah Road all carry heavy traffic, and tanks near these arteries collect more dust and suspended particles from vehicle exhaust than tanks in quieter areas.

Landmarks of Al Thaghr

Al Thaghr is bounded by Prince Majid Road running through its centre and Old Makkah Road from the south, where Al Thaghr Model Schools and Al Thaghr Hospital sit at the district's heart, generating traffic and dust throughout the day.

Before treatment

The condition of the tank decides the method

A residential district between Al Jamiah Road and King Khalid Road, home to Al Thaghr Model Schools and Al Thaghr Hospital, with a mix of villas, apartment buildings and active redevelopment projects.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer holds light but steady dust from roads and projects around Al Thaghr, and needs removal every four months to prevent particle buildup.

Light and algae

Algae and green growth appear at moderate speed here because moisture from school and hospital grounds encourages it, though external dust reduces light penetration at the same time.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls carry a thin layer of fine dust and bacteria, and need moderate pressure washing and good disinfection to remove everything that clings to the surface.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are rare in Al Thaghr tanks because tanks here are smaller than in heavy use districts and carry less load pressure.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and access hatches need regular inspection because dust can block small openings, and the vents may need separate cleaning every two months.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The vent opening and overflow pipe may clog from accumulated dust, and need frequent attention because external particles enter continuously here.

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 Jamiah Sub-Municipality

Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.

Questions about this district

Why does water cloud quickly in Al Thaghr even after cleaning?

Dust from the school, hospital and surrounding roads enters the tank constantly. We clean every four months rather than six because external particles are always entering.

Does building work around the hospital and school really affect water purity?

Yes, excavation dust and particles from cranes and trucks enter the tank through vent holes and access points during construction phases.

Do villas need more frequent cleaning than apartment blocks?

A villa may use less water but its smaller tank accumulates sediment faster. We decide by tank size and usage pattern rather than building type alone.

Does humidity from the school gardens affect the tank water?

High humidity accelerates algae growth, but dust from gardens and sports grounds is the main effect on tank water quality here.

How often should a tank in Al Thaghr specifically be cleaned?

Every four months or so, because dust and medium residential use combine. Isolated villa tanks may stretch to five months if they stand alone.

Is the brown tint in the tank floor from pipes or from outside dust?

Iron particles come from old piping or from suspended matter entering from outside with dust loads from the surrounding areas.

How much does water tank cleaning in Al Thaghr 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 Thaghr.
