Water tank sterilization in Harat Al Bahr Jeddah
Harat Al Bahr is among Jeddah's oldest historic quarters, overlooking the sea directly behind Bab Al Bunt. The ancient coral stone houses close to the harbour and docks mean that water, moisture, salt and seawater directly affect the tanks. Tanks here need strong regular sterilization because water from old wells carries mineral deposits and saltine sediment.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.
-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Harat Al Bahr
Groundwater here is saline and hard and carries mineral deposits, and sediment layers of algae and salts accumulate on tank floors and walls faster than in other quarters. The method is set out in full on the full Water tank sterilization page.
Tanks in old coral stone houses
Houses here were built from ancient coral stone and tanks are buried under ground floors or on exposed roofs. Coral stone is porous and allows salt and moisture to seep into the tank interior.
Saline water and mineral sediment
Water from old wells here is very hard and highly saline. Deposits accumulate rapidly on tank floors and walls, increasing the need for deep cleaning.
Moisture and the coastal marine environment accelerate decay
Proximity to the sea and harbour means very high humidity and salt-laden air. Tanks corrode and degrade faster, and algal films and biofilm layers grow more quickly.
The character of Harat Al Bahr
Historic district: close-set buildings, narrow lanes and ageing services
Old coral stone houses mean tanks may be buried or integrated into ancient masonry. Cleaning and sterilization require care not to damage the coral stone itself, and access may be limited in some houses.
What we read inside the tank before anything starts
An ancient coastal historic quarter south-west of Al Balad with coral stone houses near the harbour and quays. It contains Dar Radwan and the commercial Qabil Street, and its ground lies low at the waterfront edge.
Sediment on the floor
Salts and heavy minerals settle on the tank floor due to the high salinity and hardness of groundwater.
The slime film on the wall
Biofilm and algae grow on tank walls rapidly due to very high humidity, salt-laden air and hard water.
Light and heat
Supply lines from tank to taps need regular flushing because sediment can clog pipes quickly.
The lining and any cracking
Very high humidity in the quarter due to harbour proximity makes exposed tanks an ideal environment for biological growth.
The lid and the openings
Tank location in old coral houses may be beneath ground floors or on roofs, affecting access and cleaning ease.
What shows up at the tap
Post-sterilization tank inspection must focus on remaining biofilm, salt and mineral deposits, not just clarity.
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 Historic Jeddah Municipality
The Historic Jeddah municipality covers the quarters of Al Balad inside the old wall: Al Mazloum, Al Sham, Al Yaman and Al Bahr. The buildings are tall houses of coral limestone and timber rawashin, centuries old, standing shoulder to shoulder on narrow lanes that see little sun, many under restoration or partly vacant. The ground is low and close to the sea and the harbour, humidity stays high through the year, and popular souqs and eateries trade late into the night. Old timber, voids between walls and goods stores create conditions favoured by termites, cockroaches, rodents and wood boring beetles.
Questions about this district
Why do tanks in Harat Al Bahr foul faster than in other quarters?
Groundwater here is very saline and hard and carries minerals. High humidity and salt-laden air increase the rate of film and sediment formation.
Is one sterilization per year enough for tanks here?
No. Tanks here need sterilization every 3-4 months at minimum. Deposits and salt accumulate much faster than in other areas.
Does coral stone construction affect the sterilization method?
Yes. Coral stone is very porous and allows salt and moisture to seep through. Cleaning must be strong but careful not to damage the stone itself.
What causes the thick films on tank walls?
High humidity and saline water create an ideal environment for algae and salt-loving bacteria. Films form very quickly.
Is pressure washing the tank enough or do we need extra treatment?
Pressure washing removes sediment and films, but salt and mineral deposits return fast. Strong sterilization and line flushing from the furthest tap are essential here.
Is the old well water itself the problem or the tank?
Both. Saline water from the well starts the problem, but the tank allows sediment and film to accumulate. Sterilization fixes the tank, but saline water returns.
How much does water tank sterilization in Harat Al Bahr 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 Bahr.
