Water tank sterilization in Harat Al Amir Jeddah
Harat Al Amir is one of Thuwal's inner quarters, with low buildings and small tanks. Water comes from old wells and the tanks collect thick sediment and earth deposits. Deep cleaning and sterilization requires complete emptying and pressure washing the tank walls to remove the slime film.

Why the job is different in Harat Al Amir
Residents here rely on small collection tanks fed from the central municipal well, and sediment and dust accumulate quickly because groundwater here is deep and slow-moving. The method is set out in full on the full Water tank sterilization page.
Small old tanks on rooftops
Most residential buildings are low and their tanks are small and tight on rooftops. Old tanks have not been cleaned in years and sediment covers the floor in thick layers of earth and sand.
Slow groundwater and rapid buildup
Thuwal sits on the Red Sea coast where groundwater moves slowly. Tanks remain unflushed for long periods and sediment and algae accumulate on walls and floor.
Seasonal demand peaks in summer
Summer brings higher water use and the quarter receives visitors from Jeddah and neighbouring towns. Small tanks cannot meet demand and sterilization becomes essential to ensure safe water.
The character of Harat Al Amir
Mixed district: shops at street level with homes above them
A small residential quarter means small tanks on low-rise rooftops. Treatment requires a team able to access low rooftops safely and work in tight spaces around small tank installations.
What we read inside the tank before anything starts
A small residential quarter inside coastal Thuwal town, surrounded by low buildings and small shops on inner streets, near the municipality building, the mosque and schools serving the whole town.
Sediment on the floor
Sediment removal from the floor is essential because slow groundwater here deposits earth and sand rapidly on the floor of small tanks.
The slime film on the wall
Pressure washing walls removes the brown slime layer and fine algae growing on internal walls in the coastal environment.
Light and heat
Sterilizing lines from the furthest tap is necessary because small tanks have short pipe runs but sediment easily enters the pipework.
The lining and any cracking
High humidity and summer heat increase fungal and algal growth on tank walls exposed on low rooftops.
The lid and the openings
A small tank allows additional manual cleaning after pressure washing to ensure all sediment and earth residue is gone.
What shows up at the tap
Foul smell or cloudy water means bacteria buildup, and sterilization only works after all internal sediment is removed.
How we work
-
1
Inspect and record the condition
We open the hatch and work through what the tank is made of and how big it is, how deep the sediment lies, the state of the lining, whether the lid and the overflow seal, and whether there is a crack that has to be repaired before any sterilizing.
-
2
Drain and lift the sediment out
The water goes out, then the silt and sand are lifted off the floor by suction rather than pushed toward the outlet, because pushing them sends them into the house pipework and the heater.
-
3
High pressure wash
Walls, floor, corners and the area around the outlet, until the slime film is completely gone. This is the step that makes the sterilizing after it mean anything.
-
4
Sterilize, rinse, then return to service
The sterilizing agent goes onto the walls, the floor and the underside of the lid and is left for its contact time, then we rinse, refill and run the furthest tap until the whole line is clear.
What water tank sterilization includes
-
A recorded inspection
Material, capacity, sediment depth, the state of the lining, the lid and the overflow, all before any work begins.
-
Draining and sediment removal
The water out, and the silt and sand lifted off the floor instead of being pushed into the outlet and the house pipework.
-
High pressure washing
Walls, corners and around the outlet, until the biofilm that no disinfectant penetrates has gone.
-
Sterilizing the internal surfaces
A sterilizing agent meant for drinking water tanks, applied to the walls, the floor and the underside of the lid, and left for its contact time.
-
Line flush and aftercare
Rinse, refill and a flush from the furthest tap, when the water is usable again, and what to change in the filter afterwards.
-
The next cycle
We agree the right interval for your tank from how it is filled, how much sun it takes and the condition of the lid.
What is different about Thuwal Sub-Municipality
Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.
Questions about this district
Do thick sediments on the tank floor affect water safety?
Yes. Sediment and earth provide a growth medium for bacteria and fungi. Deep cleaning and complete sediment removal is necessary before sterilization.
Why do small tanks in Harat Al Amir need frequent cleaning?
Small tanks hold stagnant water longer and sediment accumulates fast. Cleaning every six months is advisable.
Does pressure washing walls remove algae and slime film?
Yes. High-pressure washing removes the slime film and algae layer from walls and floor efficiently. This is a necessary step before sterilization.
Is one sterilization enough for a small tank?
One treatment may not suffice if sediment is very thick. Sterilization only succeeds after complete cleaning and total sediment removal.
What is the difference between a polluted tank and a clean tank needing sterilization?
A clean tank needs preventive sterilization, a polluted one needs complete emptying and deep washing first. Quarters here usually need the second type.
Does cleaning and sterilization stop the strange smell from water?
Yes. The smell usually comes from sediment and bacteria. Deep cleaning and sterilization remove it permanently if the tank is sound.
How much does water tank sterilization in Harat Al Amir 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 Amir.
