Water tank sterilization in Harat Al Yaman Jeddah
Harat Al Yaman occupies the southern section inside the wall, south of Al Alawi Street toward Bab Sharif, and contains very old coral stone houses and popular souqs. Historically the quarter of builders, carpenters and perfumers, its tanks here handle multiple water sources and very high consumption loads. Humidity and perfume vapours plus chemical compounds in the air cause rapid tank and pipe fouling.

Why the job is different in Harat Al Yaman
The quarter is famous for perfumers, timber merchants and other traders. Residents and shopkeepers observe rapid staining and discoloration layers building up in tanks. The method is set out in full on the full Water tank sterilization page.
Tanks beneath perfume shops, carpentry workshops and small retail
Many tanks sit below perfume shops, carpentry workshops and small commercial units. Dust, sawdust and aromatic compounds enter the tank through cracks and open spaces.
Perfume oils, cooking fats and chemical compounds contaminate the water
Perfumers and carpenters use oily and chemical compounds in their workshops adjacent to tanks. Vapours and particles seep into the tank via pipe leaks and wall gaps.
High consumption and low pressure cause backflow contamination
Souqs, workshops and shops consume very large volumes of water especially during working hours. Pressure drops and the tank draws water back from surrounding soil and contaminants.
Landmarks of Harat Al Yaman
Harat Al Yaman occupies the southern section inside the wall south of Al Alawi Street toward Bab Sharif. Access runs through tight alleys from Souq Al Alowi past Nasseef House, Jamjoom House and Al Shaarawi House, landmarks that both define the quarter's boundaries and mark its history as a craftsmen's centre.

What we read inside the tank before anything starts
An old historic quarter to the south inside the wall, south of Al Alawi Street toward Bab Sharif. Historically known for craftsmen, builders and perfumers, it holds heritage houses such as Nasseef House, Jamjoom House and Al Shaarawi House along Souq Al Alawi. Alleys are extremely narrow and stone houses are tightly packed.
Sediment on the floor
Dust particles, sawdust, perfume and oil compounds from workshops enter the tank and accumulate on the base, discolouring the water.
The slime film on the wall
Bacteria and algae multiply rapidly on organic deposits from perfumes, oils and chemical compounds that pool in the tank.
Light and heat
Broken pipes and open gaps around the tank allow contaminants to enter from soil and shallow well layers.
The lining and any cracking
Low pressure during peak usage hours causes backflow that draws contaminants from external soil into the tank.
The lid and the openings
Tanks located near workshops and shops absorb odours and chemical vapours from the surrounding environment.
What shows up at the tap
High humidity and heat in souqs and workshops accelerate microbial and algal growth inside the tank.
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 Yaman emit strange odours?
Perfume oils, cooking fats and chemical compounds from adjacent workshops and shops seep into the water. Treatment requires deep cleaning and isolating the tank from external contaminants.
Does dust and sawdust from workshops harm the tank and water?
Yes very much. Particles enter the tank and accumulate at the base and on walls. Cleaning must be frequent and all openings checked for leaks.
Why does low pressure cause tank problems?
When pressure drops, water inside the tank draws outward instead of inward. This allows contaminants from soil and broken pipes to enter.
Is tank treatment alone sufficient or must we inspect surrounding shops and workshops?
Treatment and sterilization are essential but isolating the tank from pollution sources matters more. We may need to inspect walls, pipes and openings around the tank.
How often per year must tanks be sterilized in a high-consumption commercial quarter?
At least every two to three months due to high usage and workshop pollutants. Peak trading seasons may require even more frequent sterilization.
Does the historic quarter's past as a builders' and craftsmen's hub still affect current water quality?
Yes. Residues of materials, perfumes and oils from centuries past left deposits in soil and foundations. Old contaminants may still enter the tank through leaks.
How much does water tank sterilization in Harat Al Yaman 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 Yaman.
