Why the job is different in Al Zumurrud

Al Zumurrud tanks experience very rapid corrosion from salt and marine moisture, even when brand new. The method is set out in full on Water tank cleaning in detail.

The first reason

High marine humidity and salt penetrating concrete and metal relentlessly

Direct salt-laden air penetrates tanks very rapidly. Metals rust and concrete develops salt-driven cracks. External condensation is very heavy year-round, moisture sitting on tanks constantly. Protective coating must be very strong and reapplied every year. Standard inland tank coatings fail rapidly here.

The second reason

Chalets and resort use with intense seasonal occupancy cycles

Villas and chalets fill and empty with seasonal tourism. Tanks may be full then sit unused for weeks. Water standing in the tank for long periods can develop odour and off-taste. Cleaning before the peak season is absolutely essential.

The third reason

Algae and mould from constant humidity and light exposure

Some chalets have open or poorly protected tank openings. Constant humidity, direct light and salt encourage rapid algae and mould growth. Strong disinfection and frequent cleaning are essential. Algae can bloom within days in these conditions.

Before treatment

The condition of the tank decides the method

A coastal zone on the Red Sea itself, with very salty sandy soil, very high humidity constantly, and winds carrying salt and sea minerals throughout the year. Direct beach proximity means exposure to marine humidity without relief.

Fine brown sediment beneath shallow water

The layer on the floor

Settled matter may contain salt and bacteria from marine moisture, and needs special cleaning and multiple rinsing cycles to remove fully.

Light and algae

Light enters some rooftop tanks, and very high humidity plus salt deposits encourage algae growth at an accelerated rate.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits mix salt, calcium and algae and mould, requiring strong chemical treatment beyond standard pressure washing.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Concrete lining erodes rapidly from salt penetration, and small cracks allow seawater-mineral seepage from the surrounding salty soil.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and openings often accumulate thick white salt crusts from sea spray and need aggressive cleaning to clear.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent and overflow openings rust very rapidly and require frequent replacement with heavy-duty marine-grade salt-resistant materials.

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.

Landmarks of Al Zumurrud

Al Zumurrud tanks cluster near Omar bin Siddiq Attar Mosque and Al Khair Mosque, the district's main religious landmarks by the waterfront. Villas and chalets face the Red Sea directly, and from these two mosques most of the modern resort and coastal home tanks are easy to locate and access from the main beachside roads.

Questions about this district

Why does a brand new tank rust so quickly despite being new?

Marine salt air penetrates metals very rapidly, even new tanks. Standard protective paint may be insufficient if not marine-grade salt resistant. We recommend strong protective recoating every year and additional surface treatment.

Water standing in the chalet after travel has an off taste and is not clear. Why?

Water standing for weeks can develop bacteria, mould and small algae blooms. Pre-season cleaning and strong disinfection are essential. After long absence, complete tank drainage and full cleaning are advisable.

Do algae grow faster in Al Zumurrud than elsewhere?

Yes, much faster. Constant humidity, salt and direct light encourage algae blooms very rapidly. Strong disinfection and cleaning every month or two is necessary, not every six months.

The tank leaks through the walls from salt and moisture. Is this normal?

Some seepage occurs as salt penetrates concrete, but large cracks must be checked. Strong protective coating and external sealing reduce leakage. A new protective lining may be needed if damage is advanced.

How do we protect the tank from the sea between cleanings?

Very strong external sealing and marine-grade salt-resistant coating are essential. Mesh on openings reduces direct salt exposure. Annual cleaning and recoating are necessary to extend tank life.

Should we replace the tank instead of repeated repair?

Strong modern marine-grade tanks may justify the investment in Al Zumurrud. Standard tanks may not withstand the coastal environment long-term. We assess condition first, then recommend the best economic option.

How much does water tank cleaning in Al Zumurrud 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 Zumurrud.
