Water tank cleaning in Al Murjan Jeddah

Al Murjan is a small coastal district on Jeddah's northern corniche between King Abdulaziz Road and the waterfront, west of Al Basatin. Low density development of villas, apartment buildings and gated residential compounds face the sea across Al Murjan Street and the corniche road. Salt laden sea breezes and high humidity persist year round, soaking everything in moisture. Tanks corrode at an accelerated pace and water may carry a salt taste.

Why the job is different in Al Murjan

Coastal tanks in Al Murjan need far more frequent washing than inland neighbourhoods because salt deposits combine with sediment to create hard, difficult-to-remove layers that form much faster than in protected areas. The method is set out in full on our Water tank cleaning service.

The first reason

Sea salt particles permeate every tank

Salt particles from the sea air enter tanks through vent openings and settle with normal sediment to form a hard, salt-bonded crust on interior surfaces. This is entirely different from sediment in inland areas and requires specialised treatment to dissolve before pressure washing can move it.

The second reason

Year round high humidity accelerates corrosion

Humidity remains high throughout the year and causes metal and concrete to deteriorate rapidly. Copper pipes develop green patina quickly. Iron tanks rust from inside and outside simultaneously. Rust discolours water reddish and gives it a metallic taste that affects every tap in the property.

The third reason

Irrigated gardens create excess moisture around tanks

Gardens and lawns around villas and along the corniche are irrigated constantly. Irrigation water seeps around tank foundations and raises humidity. Excess moisture feeds fungal and bacterial growth, accelerates corrosion, and makes the tank need stronger washing and disinfection than simple cleaning achieves.

Before treatment

The condition of the tank decides the method

The neighbourhood sits directly on the Red Sea coast east of Al Basatin. King Abdulaziz Road borders it inland. Al Murjan Street runs along its spine. The north corniche is its waterfront face. Sea winds are constant and salt air is present throughout the year, from summer through winter.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment on the floor is a mixture of ordinary silt and crystallised sea salt. This creates an exceptionally hard layer that requires light acid treatment to dissolve before pressure washing can remove it.

Light and algae

Algae grows very rapidly in coastal tanks because of high humidity and light penetration. Growth may be faster and thicker than in inland neighbourhoods because salt and moisture accelerate the life cycle.

The deposit on the wall

The wall deposit is salty, extremely hard and bonds very strongly to concrete. It may need specialised acid spray treatment before pressure washing can lift it completely without damaging the substrate.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are very common in coastal concrete tanks because salt penetrates the material and breaks it down. Repairs require specialists and salt resistant compounds to prevent rapid re-opening.

The lid and the access hatch

Access lids and maintenance hatches may be severely rusted and seals may be damaged. Full replacement may be necessary to ensure humidity and salt cannot enter, and to restore watertight integrity.

The vent and the overflow pipe

Vent and overflow pipes may be blocked with crystallised salt and corrosion products. They need specialist cleaning and may require dedicated marine grade air filters to exclude particles and salt spray.

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

Water is red and has a strong metallic smell. Is the sea to blame?

Rust from pipes and an iron tank discolours water and the salt air accelerates rusting dramatically. Strong disinfection may reduce odour but will not eliminate it. Applying a protective internal lining to the tank may be necessary.

The water smells directly of sea salt. What is the cure?

Salt enters from the air and cannot be prevented entirely. Regular disinfection can reduce odour. Upgrading vent openings with marine grade air filters may help, but will not remove salt already in the tank.

The old stone tank leaks water from the walls. What is the answer?

Salt penetrates stone deeply and breaks the material down. Minor leaks may be sealed with chemical sealant, but serious seepage may need external lining replacement or full tank reconstruction.

Is an exposed rooftop tank in need of extra protection?

Yes. Exposed tanks face direct humidity, salt and sun. A strong, tight fitting lid is essential, and an external protective coating against marine corrosion is strongly recommended to slow deterioration.

How often must a coastal tank be cleaned?

Coastal tanks may need cleaning monthly or every two months. Salt, humidity and rust accumulate far faster than in inland neighbourhoods, far from the sea influence.

Could garden irrigation water enter the main tank?

If irrigation piping runs close to clean water lines, backflow and contamination may occur. Valve isolation and regular inspection of pipe separation is essential to prevent cross connection.

How much does water tank cleaning in Al Murjan 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 Murjan.
