Why the job is different in Harat Al Yaman

Tanks here show algae and sediment layers sooner than elsewhere because water moves sluggishly through stone-bound lanes and the air holds persistent damp. The method is set out in full on the full Water tank cleaning page.

The first reason

Roof tanks in older masonry buildings

Most tanks here sit atop stone houses shaded by neighbouring buildings, reducing direct sunlight and encouraging anaerobic bacteria that produce odour and discoloration. The enclosed environment accelerates biofilm formation on walls.

The second reason

Narrow lanes and manual access

We carry equipment by hand up interior stairs and across rooftops because the alleys between packed stone houses cannot fit a vehicle. The tank itself may be structurally integrated into the old building, complicating safe drainage.

The third reason

Old pipework and corrosion

Aged iron pipes leak rusty water into the tank or introduce sediment after disturbance. Neighbour tanks may cross-contaminate yours through shared masonry voids or fractured joints that have never been replaced.

Before treatment

The condition of the tank decides the method

Stone houses pressed shoulder to shoulder along alleys leave no room for heavy equipment, so the work relies on manual handling up interior stairs and across connected roofs.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer here is thicker than in newer areas because water drains slowly through shaded, damp tanks and sediment particles take longer to settle completely.

Light and algae

Green and black algae grow rapidly on the walls of these older tanks because narrow alleys cut off direct sunlight and the surrounding stone stays perpetually moist.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The brown or white film on walls is often calcium carbonate from hard water mixed with rust oxide from corroded iron pipes and fittings that have exceeded their useful life.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Cracks in the old masonry allow moisture penetration and water from outside to enter, and any tank lining present is thin and has fractured in many places.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids in historic houses are often crude concrete with poor seals, and the maintenance hatch is small and difficult to reach safely without disturbing the old roof structure.

The vent and the overflow pipe

Vent openings and overflow pipes often lack insect screens or are clogged with rust deposits because the tank infrastructure has not been updated for decades.

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 Harat Al Yaman

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

In a historic quarter like this, the tank is inseparable from the age of the building around it. Cracks, moisture and corroded pipework embedded in old walls directly affect water purity, so cleaning must address the architectural context alongside the tank itself.

Questions about this district

Is washing alone enough or must we disinfect tanks here?

Disinfection is essential in these old lanes where humidity and shade harbour dormant bacteria on walls that washing cannot reach. Chemical disinfection kills pathogens mechanical washing leaves behind.

Our tank is inside the building on the roof, does that change the work?

Yes. Shaded, sheltered tanks accumulate pathogens faster than those in sunlight. The enclosed space means anaerobic organisms thrive, requiring more frequent cleaning and stronger disinfectant action.

How do you access the tank in an old house like ours?

We climb interior stairs and cross rooftops with portable equipment suited to old buildings and tight spaces. We work around existing structure rather than bringing in heavy machinery.

Water cloudiness returns shortly after cleaning, why does this happen?

Decades old pipes may leak from neighbours into yours, or corroded iron inside shared walls releases sediment when water moves. Hairline cracks in old masonry can admit contaminated water from surrounding soil.

How often should a tank be cleaned in Harat Al Yaman specifically?

We recommend every six months instead of annually because humidity, shade and the age of these buildings accelerate sediment and bacterial growth compared to newer districts.

We find small insects and mould around our tank, are these connected?

Yes. Dampness and darkness in old buildings attract insects, and cracks in aged masonry let them shelter near the tank. Cleaning and disinfecting helps, but you may also need to seal structural gaps.

How much does water tank cleaning in Harat Al Yaman 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 Harat Al Yaman.
