Water Tank Cleaning in Al Mahjar, Jeddah
Al Mahjar is a district south west of Al Waziriyah toward the coast, near King Abdulaziz Hospital and other medical facilities and Petromin Souq. King Faisal Road and Al Mahjar Street cut through it. South Jeddah carries diesel soot and workshop dust from heavy traffic and the refinery, and water picks up all of this. Tanks here hold industrial sediment and faint salt from coastal humidity. The pressure of industry and sea meet in one neighbourhood.

What changes about water tank cleaning in Al Mahjar
A shared tank in Al Mahjar may hold diesel dust and faint salt from coastal humidity and heavy traffic at the same time. For the method itself, see the full water tank cleaning page.
-
The first reason
Heavy King Faisal Road carries diesel soot and the refinery is near
King Faisal Road passes through Al Mahjar with heavy vehicles every day, and the refinery is very close. Smoke, soot and oily dust from diesel and refinery operations float in the air. The tank draws this polluted oily air continuously.
-
The second reason
Salty coastal humidity damages seals and covers and enters the tank
Al Mahjar is close to the shore and salt-laden humidity is high. Covers and seals deteriorate quickly from salt and moisture, so the tank may not seal completely. Salt enters the tank through openings and damaged seals.
-
The third reason
Hospitals and the market around the tank mean intensive mixed use
Al Mahjar holds hospitals, Petromin Souq and residential housing all together, so water is drawn for medical, commercial and domestic use. Pressure fluctuates constantly and the tank carries heavy uneven demand.
What water tank cleaning covers in Al Mahjar
Al Mahjar is a south Jeddah district west of Al Waziriyah toward the coast, home to King Abdulaziz Hospital and other hospitals and Petromin Souq, with King Faisal Road and Al Mahjar Street cutting through it.
-
Tank checked before we start
Tank inspection in Al Mahjar reveals dark brown sediment mixed with a metallic layer from salt and industrial soot on the walls.
-
Old water drained out
Draining old water from a tank in Al Mahjar produces dark brown water with a faint diesel and salt smell.
-
Sediment vacuumed from the bottom
Sediment vacuumed from the floor removes a thick layer of industrial deposits and salt that is difficult to extract completely.
-
Walls and floor scrubbed
Manual scrubbing of walls and floor removes oily and salty layers mixed with ordinary sediment that has stuck to the surfaces.
-
Interior surfaces disinfected
Disinfecting interior surfaces in an Al Mahjar tank requires strong treatment to kill bacteria from industrial sediment and salt.
-
Final rinse and lid check
Final rinse and lid check ensures the tank is sealed tight against further entry of salt and soot from King Faisal Road and the nearby refinery.
Not included

How a tank is actually cleaned
-
1
Isolate and drain fully
The supply into the tank is shut and the tank is drained completely.
-
2
Remove the sediment by hand
The sludge on the floor is scooped and pumped out first.
-
3
Scrub walls and floor bare
The biofilm on the walls is physically scrubbed off.
-
4
Disinfect the bare surfaces
With the walls and floor clean, a disinfectant made for drinking-water storage is applied and given time to act on every surface.
-
5
Rinse and pump clear
The disinfectant and any loosened residue are rinsed down and pumped out, so the first tank of water after us is not carrying it.
-
6
Check the lid, then refill with you
We check the cover seal and inlet before refilling, so dust and insects stay out, then start the refill while you watch it run clear.

Why us for this job in particular
A team, done in one visit
We send a team, not one person, so a tank is drained, cleaned, disinfected and refilled in a single visit rather than left open for days.
We check the cause, not just the tank
We look at the lid seal and inlet, because a tank that got dirty fast usually has a way in.
You watch it refill clear
Nothing is closed until the tank is refilling and you have seen the water run clean.
From our work
Photographs from real jobs carried out by the crew.
The job is not closed before you approve it
The commitment is simple enough to actually keep: we do not leave until the tank is disinfected, refilling, and you have seen it for yourself.
What is different about South Jeddah
South Jeddah runs from the port and the industrial city down towards Al Khumrah, and homes here sit between the sea and the heavy goods roads. The dust is darker and oilier than in the north, a mix of diesel soot and workshop grit, and it clings to net curtains, window sills and the tops of kitchen cupboards. Floors in the older low rise housing are often plain cement or ceramic tile that darkens where soot is walked in. Humidity from the coast adds mildew in bathrooms and a musty smell in stored fabrics.
Questions about water tank cleaning in Al Mahjar
Does salt from the sea enter an Al Mahjar tank directly?
Salt enters indirectly through air, humidity and damaged seals. Salt may not be obvious in the water but it damages pipes and seals.
Does dust from the refinery and heavy roads contaminate water in Al Mahjar?
Yes, oily dust and diesel float in the air and enter the tank. Water may carry colour and taste from this contamination.
Does a tank in an industrial and coastal zone need more frequent cleaning?
Yes, much more frequently. Every four to six months instead of yearly. Industrial pollution and coastal salt accelerate sediment build-up rapidly.
Does cleaning take longer in Al Mahjar than in other districts?
It may take three to four hours. Industrial sediment and salt may be difficult to remove completely and require careful treatment.
Is water after cleaning in Al Mahjar safe for medical use in hospitals?
After full disinfection and final rinsing, yes, water is safe. However, hospitals may have special quality standards requiring separate testing.
Are pipes in Al Mahjar affected by salt and industrial soot?
Yes, salt and rust deposit in pipes faster than elsewhere. Pipe replacement may become necessary periodically.
Can you clean a rooftop tank with a small opening?
Usually yes. A tight rooftop unit with a narrow hatch takes more care and time than a wide ground tank, but the cleaning is the same. Access is one of the things we ask about up front so the price and duration are right before we come.
How often should a tank be cleaned?
On a regular cycle rather than once and forgotten, and sooner if you notice grit, a taste or a cloudy tint.
How much does water tank cleaning in Al Mahjar cost?
It is set after the inspection, because it follows the size of the job, the materials involved and their condition. Send photos on WhatsApp and we will give you an estimate before we reach Al Mahjar.
