Water tank cleaning in Al Salihiyah Jeddah

Al Salihiyah is a new district in north Jeddah, east of Al Hamdaniyah and south of Al Falah and Al Rahmaniyah. Recent villas and apartments sit on subdivided plots with vacant land still lying between the buildings. Tanks here are new but they fill from water networks that are still under construction. Sediment accumulates at an unusual pace and the challenges are those of a developing area, not an established neighbourhood.

Why the job is different in Al Salihiyah

New tanks in Al Salihiyah need frequent washing in their first year because of particles released by new pipework and continuous dust from adjacent vacant plots that cannot yet be built or landscaped. The method is set out in full on the full Water tank cleaning page.

The first reason

Water networks still under continuous expansion

The main water mains themselves are not yet complete, and each new connection release welding particles and initial rust forming inside new pipes. Tanks fill faster than they should with contamination, and district water may arrive in different colours depending on which section of new pipe is in use.

The second reason

Vacant land between buildings releases dust

Bare plots around villas and apartments shed dust clouds in any wind. Even covered tanks draw this material in through vent openings. Water may become turbid within days, even in newly cleaned tanks, because the source of dust is constant and unobstructed.

The third reason

Large road expansion scheme underway nearby

Al Furusiyah Street is a recent upgrade and new road projects surround the district. Excavation and construction release enormous dust volumes and sand into the air. Tanks located near these projects become dirty far faster than tanks in quiet areas.

The character of Al Salihiyah

New development: ongoing construction and vacant plots between the homes

In a newly developed district, the new tank faces challenges entirely different from those of old areas. The problem is not age but emerging pipes, ongoing construction and vacant plots that send dust endlessly into the air without respite.

Before treatment

The condition of the tank decides the method

The district lies in the Taybah region east of Al Hamdaniyah, with spacious plots and a planned street grid. New building jumps from one plot to the next, leaving vacant land that collects dust and sand between structures.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment on the floor is a mixture of metal particles from new pipes and dust from vacant plots. This blend is lighter and easier to remove than the settled silt that accumulates over years in established districts.

Light and algae

Algae does not grow rapidly initially because water has not stabilised, but if the tank is not kept well covered, rapid growth can start because light and airborne dust both feed it in newly developing areas.

The deposit on the wall

The wall deposit in a new tank is thin and easy to remove, but may contain metal particles from pipes that can stain. Cleaning removes these easily and completely without abrading the concrete.

The lining and hairline cracks

Hairline cracks may appear in new concrete tanks after initial pressurisation or due to manufacturing defects. Close inspection before chemical treatment is essential to catch these before they enlarge.

The lid and the access hatch

The access lid and maintenance hatch in new villas are in good condition but may be covered in construction dust and cement powder. Cleaning the surrounding area is necessary before opening.

Overflow and vent pipes in new villas may be unobstructed but may not be correctly installed. Inspection and confirmation of proper function is required before signing off on any new 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 Salihiyah

Reaching Al Salihiyah tanks is straightforward via Al Furusiyah Street, which runs north through the district providing direct access. Abdulrahman bin Awf Mosque provides a central landmark, whilst Al Salihiyah Health Centre marks the eastern perimeter for precise navigation to individual properties.

Questions about this district

The new villa tap water has an odd colour. What causes it?

New water mains carry metal particles from the pipes themselves. The tank may be clean but the line from the main station carries contamination. Cleaning must include a complete flush of the district's main water lines, not just the tank.

Should the new villa tank be cleaned before we move in?

Absolutely essential. Even if the tank looks spotless, manufacturing and installation debris may be inside. One thorough cleaning before occupancy ensures water safety from day one, not after staining or illness occurs.

Vacant plots next to the villa kick up dust. Does this affect the tank?

Yes. Dust enters the tank through vent openings. If the vacant plots will remain bare for an extended period, fitting air filters to vent openings can significantly reduce dust entry and keep water clearer longer.

New apartment water is cloudy and smells metallic. Why?

New tanks and new pipes release metallic odours in the first weeks. High pressure washing may reduce this but the smell may take one or two weeks to disappear entirely as the pipes stabilise.

How often must the new villa tank be cleaned in year one?

It may need cleaning every two months in year one because of particles from new pipes and dust from surrounding vacant plots. After year one, frequency typically drops to three to four times yearly as the infrastructure stabilises.

Is Al Salihiyah tank cleaning different from an older district like Al Hamdaniyah?

Fundamentally different. Al Salihiyah is new with the challenges of fresh construction and new pipes. Al Hamdaniyah is older and its tanks and pipes have settled. The sediment profiles and problems are completely distinct.

How much does water tank cleaning in Al Salihiyah 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 Salihiyah.
