Why the job is different in Al Ruwais

Al Ruwais tanks develop a strange metallic taste within weeks of cleaning because sea humidity encourages rapid bacterial growth and old pipes release minerals into stored water. The method is set out in full on Water tank cleaning in detail.

The first reason

Old tanks carry mineral sediment layers

Al Ruwais apartment blocks hold tanks from decades past, and stagnant water in them has deposited iron and calcium minerals over the years. Each new cleaning stirs these deposits again, adding colour and taste that younger tanks do not release.

The second reason

Sea humidity accelerates algae growth

Damp air from the sea enters the tank through vent holes and access points, and algae thrives far faster here than in inland districts. We need strong disinfection and frequent washing because humidity alone will regrow algae within weeks.

The third reason

Old pipework releases oxidised minerals

Water pipes and drainage lines in old Al Ruwais blocks are often very old, and rust particles enter the tank from connected piping. The water needs regular cleaning to remove these suspended particles, which no disinfection can eliminate.

Al Ruwais sits about 1.5 km from Al Sharafiyah and about 3.5 km from Al Wurud.

Before treatment

The condition of the tank decides the method

A district near the Corniche and the port, with old and new apartment blocks and quarters undergoing redevelopment. Salt laden air and high humidity persist year round, affecting everything metal and organic.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer in Al Ruwais tanks holds minerals and oxidised particles from old piping, and requires full drainage and repeated rinsing to clear the discolouration.

Light and algae

Algae grows much faster here because sea humidity is very high and limited ventilation in narrow quarters provides no natural drying that would suppress it.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls carry a thin film of bacteria and dead algae, and need strong disinfection after washing because humidity will regrow growth rapidly if disinfection is weak.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Plastic tank lining is affected by high humidity and salt laden air, and hairline cracks may appear faster here than in districts away from the sea.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids rust at terrifying speed here because salt and humidity are both present, and replacement may be needed every two years rather than every five.

The vent and the overflow pipe

The overflow pipe may clog from algae and sediment, and the vent opening needs repeated cleaning because humidity drives rapid bacterial growth on any surface.

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 Al Sharafiyah Sub-Municipality

The Al Sharafiyah sub municipality runs across central Jeddah from Al Ruwais near the Corniche eastwards through Al Sharafiyah, Al Wurud and Bani Malik to Al Naseem at the Haramain Road. It was among the first areas to grow beyond the old wall, and it is dominated by dense apartment blocks over shops along King Fahd Road and Palestine Street, with old popular quarters, the Bani Malik market, car workshops and storerooms. Ageing buildings, worn drainage and the refuse of restaurants and markets make cockroaches and rodents the most persistent pests, and humidity rises towards the sea.

Questions about this district

Our water tastes metallic and strange within a week of cleaning. Why?

Sea humidity and old piping add minerals and bacteria quickly. We must clean every two to three months here rather than six, because local conditions speed water degradation.

Does salt from the sea actually enter the tank water?

Salt itself does not penetrate easily, but the high humidity causes iron and copper pipes to rust, and this oxidation changes the taste and colour of the water.

Why do Al Ruwais tanks need more frequent cleaning than other districts?

Proximity to the Corniche raises humidity, old blocks hold older pipes, bacteria multiply faster here than inland, and redevelopment areas add dust loads to the air.

Do green algae in the tank come from light or from humidity?

Both contribute, but the high humidity here is the driving factor. Even well sealed tanks admit humid air when access hatches open, and that moisture carries the spores algae needs.

Our hot water is always worse quality than cold water from the same tank. Why?

Electric heater tanks in old Al Ruwais blocks are often themselves very old, and rust accumulates rapidly in the heating vessel. Cold water passes only through the main storage tank.

Does tank cleaning solve the metallic taste permanently?

Cleaning removes current sediment, but old pipes regenerate minerals within weeks. Solving this fully may require replacing sections of the older pipework that feeds the tank.

How much does water tank cleaning in Al Ruwais 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 Ruwais.
