Why the job is different in Harat Al Sarahin

Harat Al Sarahin tanks carry sea salt in the air, lids and joints rust at terrifying speed, and bacteria thrive far faster here than in inland districts. The method is set out in full on Water tank cleaning in detail.

The first reason

Very old houses with tanks decades old

Harat Al Sarahin holds mud built and heritage construction very old, and its attached tanks carry the same age and wear. Rust, leakage and bacterial growth happen at terrifying speed.

The second reason

Salt and very high sea humidity always present

Thuwal sits directly on the coast, and salt laden air enters every corner of the quarter. Tank lids and pipes rust at terrifying speed, and water tastes of salt.

The third reason

Coastal life leaves permanent humidity in tanks

Humidity never drops in Harat Al Sarahin even in summer, and bacteria and algae grow year round without pause. Salt air and permanently high moisture create perfect conditions for growth.

Before treatment

The condition of the tank decides the method

An old coastal quarter in Thuwal, mud built and popular houses, clustered families in the manner of coastal villages, near Thuwal Harbour and Thuwal Corniche.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer in Harat Al Sarahin tanks is heavy and contains salt, rust and bacteria, and needs full removal every two months or so.

Light and algae

Algae grows very rapidly here because sea humidity is very high all year round, and light entering through old openings accelerates growth.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls carry a thick layer of salt, bacteria and rust, and need very high pressure washing and strong disinfection.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Plastic lining in very old tanks may already be cracked, and needs close inspection that may lead to tank replacement.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and joints corrode at terrifying speed from salt and humidity, and may need replacement every year.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The vent opening and overflow pipe are caked with salt, rust and algae, and need vigorous repeated cleaning and may require replacement.

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.

The character of Harat Al Sarahin

Mixed district: shops at street level with homes above them

A mixed district in an old coastal quarter means the tank serves clustered families in old mud built and popular houses. Salt and permanently high humidity are the main factor, and frequent cleaning is necessary to prevent tank failure.

Questions about this district

Is salty taste in the water normal here on the coast?

Salt itself may not enter water easily, but salt and humidity cause pipe and tank rust, and this changes the taste. Frequent cleaning is necessary.

Why do tank lids rust at such terrifying speed here?

Salt carried directly from the sea causes very rapid rust. Replacement may be needed every one to eighteen months rather than five years.

Is water quality worse in Harat Al Sarahin than other parts of Thuwal?

Harat Al Sarahin sits very close to the shore and the harbour, and salt and humidity are highest here. Water needs more intensive cleaning than inland areas.

Will a plastic tank lining survive the salt and humidity?

Plastic is better than metal, but constantly high salt and humidity may cause cracks after a few years.

How often should a tank in such a coastal quarter be cleaned?

Every two to three months at least, because salt, humidity and bacteria grow at terrifying speed. Inland areas might go six months.

Can sudden pressure loss be salt blocking the pipes?

Salt and rust may eventually block small piping. If pressure drops suddenly, the supply line may need inspection.

How much does water tank cleaning in Harat Al Sarahin 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 Harat Al Sarahin.
