Why the job is different in Al Ammariyah

In the oldest quarters of Jeddah here, the rooftop tank leaks water from all sides, humidity on the walls is extremely high, and rats and insects live around the old building. The method is set out in full on our Water tank cleaning service.

The first reason

Nearness to the port and sea raises salt, humidity and marine bacteria

The Islamic Port and the sea are very close. Salt laden humidity rises year round and enters the tank through cracks and small holes. Salt deposits rapidly on walls and pipes and causes fast rust. Tiny marine bacteria enter on humid air. Disinfection here must be strong and frequent because marine bacteria resist ordinary measures.

The second reason

Very old building and ancient pipes leak and draw in contaminated water

Ancient pipes leak continuously and pressure is very low. Contaminated water from open drains enters through cracks and holes in pipes and tank. The tank itself is cracked from the cycles of heat and cold and changing humidity through the year. Cracks grow wider over time.

The third reason

Open drains around the old building bring foul air, rodents and insects

The narrow alleys around the building have open sewers, food waste and dead animals. The smell is intense and rats and cockroaches nest in the ground and around the openings. These contaminants enter the tank through simple vents and hairline cracks. Frequent cleaning is only a temporary fix.

Before treatment

The condition of the tank decides the method

Al Ammariyah is a very old central district around the Eve Cemetery, with ancient apartment buildings on extremely narrow streets near Makkah Road, very close to the sea and the Islamic Port, which keeps humidity high all year.

Fine brown sediment beneath shallow water

The layer on the floor

The floor collects a thick layer of red and black rust from ancient pipes and marine bacteria that grows over years.

Light and algae

Walls bear green and black algae from high humidity, salt and weak light seeping through cracks.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The deposit on the walls is a mix of rust, salt and bacterial colonies that stick hard and need strong chemical cleaning.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Weak lining and cracks in the old tank allow moisture, salt and bacteria from outside to seep inward easily.

The lid of a water tank on a building roof

The lid and the access hatch

The simple tank cover and wide vents allow insects, rodents and dust from the surrounding alleys to enter freely.

The vent and the overflow pipe

Overflow and vent pipes are completely corroded and weak, leaking bacteria laden water, and may need full 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.

What is different about Al Balad Sub-Municipality

Al Balad sub municipality covers the historic core of Jeddah and the districts that first grew outside its wall. Its building stock is the oldest in the city: heritage stone houses and apartment blocks from past decades, threaded with hotels, shops and crowded popular markets around Bab Makkah, Bab Sharif and the Kandarah Souq. Nearness to the sea, the Islamic Port and the Arbaeen lagoon keeps humidity high all year, water and drainage networks are old, and narrow lanes, dense eateries and commercial storerooms put food and shelter within reach at every corner.

Questions about this district

Water from the tap is black sometimes and cloudy at other times. What is the answer?

Black indicates bacteria and rust from very old pipes and the tank. Cloudy indicates mineral sediment and moisture. The root cause is the ancient pipes and weak tank, and cleaning alone cannot solve the permanent problem.

The building is old, the tank sits on the roof, and the roof seeps water. Is that normal?

It is not truly normal. A seeping roof means the building needs waterproofing repair. Seeping water can enter the tank through cracks if the tank sits near the roof edge. The roof structure may need rebuilding or the tank may need replacement.

The old tank and very damp walls. Is there a connection between the leak and the dampness?

Yes. The tank leaks water onto the walls and salt laden sea humidity seeps in from outside. Together these two make the walls extremely damp. Damp walls cause paint to peel, and algae and fungus spread everywhere.

Rats and cockroaches live around the building near the tank. Can they enter it?

Rats and cockroaches live in the open drains around the building and enter the tank through simple vents and small cracks. The old tank has no protection. Frequent cleaning and improved covers and vents are essential.

Does sea salt enter the tank and make the water taste salty?

Salt deposits on walls and pipes but does not usually reach the water in quantities large enough to taste salty unless the site is extremely close to the shore. But salt corrodes pipes and tanks, and this corrosion changes the water.

The street is very narrow and the building is old. How do you reach the tank on the roof?

The street is extremely narrow and shared staircases are tight and steep. Cleaning equipment must be carried up carefully by hand. The work takes much longer than in modern districts, and climbing ancient stairs and unstable roofs is hazardous.

How much does water tank cleaning in Al Ammariyah 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 Ammariyah.
