Why the job is different in Al Tandabawi

Tanks in Al Tandabawi suffer extreme seasonal pressure in Hajj and Umrah seasons, consumption spikes from a few people to thousands daily within weeks, then drops to nothing, stressing the system repeatedly. The method is set out in full on how we approach Water tank cleaning.

The first reason

Intense seasonal pressure cycling

Al Tandabawi sits beside the Haram with many small hotels, during seasons tanks serve thousands of pilgrims daily then stand nearly empty, cycling repeatedly. This stress accelerates wear and corrosion far faster than constant use.

The second reason

Old dense construction and trapped pipes

Al Tandabawi is very old with medieval street patterns, plumbing is intricate and ancient, tanks may be built into lane foundations. Repair or replacement is extremely difficult and sometimes impossible without demolition.

The third reason

Hillside ground and difficult drainage

Al Tandabawi sits on sloping ground with groundwater potentially very close. Old drainage may not handle seasonal flood loads or excess water from rainfall on the hillside.

The character of Al Tandabawi

Historic district: close-set buildings, narrow lanes and ageing services

Old quarters near the Haram mean tanks under extreme seasonal pressure, with unique challenges from ongoing demolition and rebuilding around Jabal Omar and the central development zone.

Before treatment

The condition of the tank decides the method

An old suburb near the central zone and the Grand Mosque, lanes tightly packed with old buildings and new additions, small hotels and cafes, very old drainage networks, on sloping hillside ground.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment on tank floors is thick and coated with bacterial biofilm and minerals, accumulation accelerates fast during seasons from intense use.

Light and algae

Algae may develop during quiet periods when water sits still, red algae may appear in abandoned tanks between peak seasons.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls carry thick deposits of biofilm and minerals from seasonal cycling and high mineral water drawn repeatedly.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are present in most old tanks, repeated pressure cycling and hillside ground stress accelerates fracturing.

The lid of a water tank on a building roof

The lid and the access hatch

Tank covers may be rusty or loose from repeated pressure cycling and may leak from vibration and stress.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent and overflow openings clog from dust and mineral crusts, repeated pressure may damage overflow pipes.

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 Ajyad Sub-Municipality

Ajyad sub municipality takes in the districts that press against the Grand Mosque from the south and west: Ajyad, Al Hajlah, Al Shubaikah, Al Tandabawi and Al Mansour. Hotels and rented apartment blocks for Umrah visitors stack up along Ajyad Street and Ibrahim Al Khalil Street, with kitchens and restaurants running aday and night in season. Behind them, Al Shubaikah and Al Tandabawi keep narrow old lanes on hillside ground where buildings and drains are ageing, and demolition and construction sites are a constant presence around Jabal Omar and the central zone.

Questions about this district

How often should an Al Tandabawi tank be cleaned?

Al Tandabawi is highly seasonal. Cleaning immediately before Hajj and Umrah seasons is essential for water safety and occupant health.

Does water foul quickly under heavy seasonal use?

Yes. During seasons tanks serve thousands daily and sediment and bacteria accumulate extremely fast from the intense load.

The tank sits empty outside season. Does that damage it?

Empty tanks suffer corrosion from humidity and bacteria grow in stagnant water. Regular cleaning is necessary even during light seasons.

Do small hotels in Al Tandabawi need special cleaning?

Small hotels use water very heavily and rapidly, needing cleaning every month or two to maintain quality for guests.

The tank smells foul at season start. Why?

Empty humid tanks develop specialised bacteria growth. Intensive cleaning and disinfection before season is essential.

Does hillside ground affect the tank?

Yes. Moisture from soil and close groundwater can cause seepage from tank sides and base, especially after rain.

How much does water tank cleaning in Al Tandabawi 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 Tandabawi.
