Why the job is different in Al Nahdah

Sea humidity is high throughout the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround villa plots and hold water. The method is set out in full on our Water tank cleaning service.

The first reason

Sea humidity speeds up algae and mould growth

Al Nahdah sits very close to the sea and humidity is high year round. Tanks face low light, damp soil and salt air. This combination speeds up green algae and black mould on walls and floors. Bacteria grow much faster than they would in dry areas.

The second reason

Irrigated greens create a damp environment round the tanks

Gardens and lawns round the corniche and round villa plots are watered continuously. Excess water gathers round tanks and their foundations. Standing water and constant moisture create a perfect home for insects, rodents and bacteria to breed.

The third reason

Closed chalets and rest houses harbour insects

Along the creek are rest houses and chalets that stand empty for long spells. The tanks inside sit idle and untouched. Standing water, damp air and darkness create perfect shelter for insects and rodents. They settle and breed in weeks.

Landmarks of Al Nahdah

Al Nahdah sits between King Abdulaziz Road and Prince Sultan Road along Hira Street, and closeness to the corniche and the park makes access straightforward. Hira Plaza and Al Nahdah Park provide clear local landmarks.

Before treatment

The condition of the tank decides the method

Al Nahdah runs between King Abdulaziz Road and Prince Sultan Road along Hira Street in northern Jeddah, a short distance from the sea. It is residential in its inner blocks with villas and apartment buildings, while the main streets carry dense trade in shops and eateries.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer holds wet mould and organic sediment, and constant humidity makes cleaning harder and more important.

Light and algae

Green algae, black and brown mould and fungi grow fast because low light, damp and nutrients are always available.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls are coated thickly with green and black algae, brown mould, grey and black fungi.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Cement render is cracked from continuous damp and thermal expansion and contraction, and cracks let dirty water seep in from soil.

The lid of a water tank on a building roof

The lid and the access hatch

Metal tank lids are heavily rusted and hinges may not work. The lid may be heavy and unsafe from rust and decay.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The air vent and overflow pipe are clogged with mould and sea algae, and foul smell signals fast bacteria growth.

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 Obhur Sub-Municipality

Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.

Questions about this district

Does tank water in Al Nahdah taste salty?

If the tank has cracks or sits very close to the sea, salt water may seep in slowly. Strange taste or saltiness calls for close inspection for cracks.

High sea humidity means more frequent cleaning?

Yes, very much so. Humidity helps algae, mould and bacteria grow fast. We recommend cleaning every one and a half to two months.

Irrigated gardens beside the tank: do they harm it?

Yes, continuous watering raises humidity and water may seep into the tank from outside if it has cracks. Regular inspection matters.

Empty chalets and rest houses next door: do insects spread to the house?

Yes, empty chalets are shelters for insects and rodents. Nearness may mean they spread to neighbouring homes especially if tank water is contaminated.

Dense shopping streets feed the insects?

Yes, restaurants and shops are food sources. Cockroaches, flies and ants find endless supply, and tanks are their shelter from drying.

Is living further into the district enough to avoid sea problems?

No, humidity is high all through the district and affects every tank. Distance does not fully shield from salt and damp air.

How much does water tank cleaning in Al Nahdah 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 Nahdah.
