Why the job is different in North Obhur

High sea humidity and salt laden winds keep walls and pipes damp most of the year, and the irrigated lawns round houses hold standing water around the tanks themselves. The method is set out in full on how we approach Water tank cleaning.

The first reason

Irrigated grounds round villas and resorts stay wet

Villas and resorts in North Obhur have large gardens watered continuously by drip lines and sprinklers. Excess water collects round tanks and foundations, and humidity stays high all year, which helps algae, mould and bacteria grow rapidly.

The second reason

Salt air and damp attack tanks from outside

Sea air is salty and damp, and salt settles on metal and the outer faces of the tank. Moisture penetrates fine cracks and joints, and seawater or brackish water may seep in from outside toward the tank.

The third reason

Closed chalets and vacant resorts shelter insects

Along the shore are rest houses and chalets that stand closed for long spells, and the tanks inside them sit idle. This emptiness lets insects and rodents settle and colonise the tank, and standing water becomes the perfect place for them to breed and thrive.

Landmarks of North Obhur

North Obhur sits directly on the Sharm Obhur seafront and North Obhur Beach runs along the full length of the shoreline. Prince Abdullah Al Faisal Street crosses the district and makes access to homes and resorts straightforward.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer holds mineral sediment and salt, and deposits are thicker in tanks close to the sea.

Light and algae

Green algae and black mould grow fast in damp conditions rich in nutrients from salt water and the humid air.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls are coated with white salt and green algae from sea mould and damp fungi.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Cement render is attacked by salt and damp and cracks faster than renders on inland tanks, and cracks allow salty water to seep in.

The lid of a water tank on a building roof

The lid and the access hatch

Metal tank lids are heavily rusted and hinges fail from salt and corrosion. The lid may be heavy and unsafe from rust.

The vent and the overflow pipe

The air vent and overflow pipe are clogged with salt and sea algae, and foul smells signal rapid sea 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 Dhahban Sub-Municipality

Dhahban sub municipality is the northern coastal strip of Jeddah, running from the north bank of Sharm Obhur up to the old village of Dhahban and Salman Bay. Its districts are recently built, with owner occupied villas and apartments, beach resorts and chalets on the shore, and land subdivisions still being developed. Nearness to the sea keeps humidity high all year, irrigated lawns in villas, resorts and district parks hold water, Wadi Obhur and the vacant plots between buildings give rodents and reptiles shelter, and the old fishing village of Dhahban gives the far north a rural edge.

Questions about this district

Does tank water get salty from the sea?

Yes, if the tank is close to the sea and has cracks, salty or brackish water may seep in. Strange taste or smell signals a leak from outside.

Do the irrigated grounds round the tank raise the humidity?

Very much so. Continuous watering raises humidity round the tank and its foundations. Underground tanks may leak because of this high moisture.

Chalets closed for long spells: does the tank inside get dirty?

Yes, standing water and insects that enter the tank during the long closure cause pollution. We recommend cleaning the tank before a chalet opens again.

Does salt get in the tank from the air or through cracks?

Salt settles on the outside of the tank from the air. But if the tank has cracks, damp and murky water may enter through them.

Sea humidity all year means frequent cleaning?

Yes, we suggest cleaning every two or three months. Continuous damp speeds up bacterial and algal growth.

Should we check the outer walls and foundations when cleaning?

Yes, damp walls and leaking foundations may be the source of infiltration. Inspection is important and we may recommend repairs to the structure.

How much does water tank cleaning in North Obhur 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 North Obhur.
