Water tank cleaning in Al Khalidiyah Jeddah

Al Khalidiyah is a villa and gated compound district near the northern corniche, with each villa set on its own plot surrounded by a boundary wall. Irrigated gardens and green spaces surround each home and hold moisture at higher levels, and soil from the gardens may enter the tank through leaking irrigation lines or seepage from the surrounding ground.

Why the job is different in Al Khalidiyah

Tanks in villas receive water of high quality but high humidity from irrigated gardens and surrounding soil may speed the growth of bacteria and algae. The method is set out in full on Water tank cleaning in detail.

The first reason

Irrigated gardens and green spaces raise humidity continuously

Every villa has a garden watered constantly, and green spaces hold moisture. Leachate from irrigation may reach the tank, and air around tanks stays very damp from continuous garden watering.

The second reason

Garden soil and fertiliser may seep toward the tank

Garden excavation and repeated irrigation can create pressure on villa foundations, and soil and fertiliser may seep slowly toward the tank. Bacteria from soil may enter if small cracks exist.

The third reason

Gated compounds may have shared water systems

Large compounds often have a shared main tank and internal distribution pipes, so a problem in the main tank affects all villas. Cleaning one villa tank may not be sufficient if the main network is contaminated.

Before treatment

The condition of the tank decides the method

A villa district north of Jeddah between King Abdulaziz Road and Saud Al Faisal Road, with large villas and gated compounds with private gardens, bordering Al Andalus, Al Rawdah, Al Salamah and Al Zahra.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment may contain traces of garden soil and fertiliser if seepage has occurred, and is stickier than normal sediment.

Light and algae

Algae grows very quickly because of high humidity, sunlight and nutrients from the surrounding soil.

The deposit on the wall

Wall deposits may be green from algae growth and contain traces of minerals and fertiliser.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may serve as a path for irrigation water seepage from outside to inside the tank.

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 Khalidiyah

In Al Khalidiyah, tanks are located in the private gardens of walled villas, each villa having its own separate space. Access is usually from the roof or a side courtyard of the villa after passing through the compound or villa gate, and some villas may be distant from the main road.

Questions about this district

Can irrigation water from the garden enter the tank?

Yes if the tank is close to the garden and small cracks exist. Leachate may seep in when tank pressure changes.

Why does water turn green so fast in Al Khalidiyah?

High humidity from gardens and green spaces provides ideal conditions for algae growth. Sunlight, moisture and nutrients from soil accelerate it.

Can garden fertiliser contaminate the tank water?

It can if it seeps from surrounding soil. Organic fertiliser can cause rapid bacterial growth in the tank.

In compounds, who is responsible for cleaning the main tank?

Usually the management or the residents' council, but neglect is common. Make sure the main tank is cleaned regularly.

Do we need to protect our tank from the adjacent garden?

Yes. Make sure the tank is protected from irrigation water seepage. Checking seals and cracks is crucial in villas.

Is frequent cleaning necessary because of high humidity?

Yes. You may need cleaning every six months instead of annually. Humidity and nutrients mean faster algae and bacterial growth.

How much does water tank cleaning in Al Khalidiyah 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 Khalidiyah.
