Water tank sterilization in Harat Al Mazloum Jeddah
Harat Al Mazloum is one of Jeddah's oldest quarters and contains ancient coral stone houses and narrow trading souqs such as Souq Al Jami. The buildings are extremely old and tanks may be buried beneath house floors or placed in cramped, hard-to-reach spaces. Coastal humidity and salt spray cause rust and sediment layers to accumulate rapidly in these heritage structures.

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 Mazloum
Residents and shopkeepers report discoloured water and salty taste especially in summer and high humidity months. The method is set out in full on the full Water tank sterilization page.
Buried or hidden tanks in old houses
Most tanks in Harat Al Mazloum are set beneath floors or in very cramped lower rooms. Access requires removing old wooden floorboards and navigating tight, deep spaces.
Coastal salt and humidity accelerate contamination
The quarter sits close to sea and saline humidity deposits on tank walls. Red and brown accumulations from iron oxide appear quickly and salty taste bothers residents.
Old pipework and porous coral stone piping
Pipes in these houses are very old, made from weak coral material or poor-grade metal. Pinholes and rust contaminate the water before it reaches the tank.
The character of Harat Al Mazloum
Historic district: close-set buildings, narrow lanes and ageing services
A very old historic quarter built in coral stone and raw timber. Tanks here are hidden in ancient houses and hard to reach, so treatment must account for the quarter's constrained heritage layout and requires patient navigation of buried tanks accessed through lower rooms and floor cavities.
What we read inside the tank before anything starts
A very old historic quarter inside the ancient city wall in the northeast, north of Al Alawi Street, with coral stone houses built over two centuries ago, traditional souqs and narrow alleys. It reaches east to Bab Makkah and is anchored by the historic Al Shafi'i Mosque.
Sediment on the floor
Red and brown iron oxide and salt deposits build up on the tank base, especially in corners and edge seams.
The slime film on the wall
Old houses carry permanent moisture in foundations and lower floors, and water seepage from surrounding soil contaminates the tank.
Light and heat
Coral and old metal pipes carry rust particles and metallic sediment that fall into the tank with running water.
The lining and any cracking
Coastal salt humidity is present year-round in the quarter, which sits very close to the sea.
The lid and the openings
Buried tanks beneath floors and lower rooms collect seeping water and debris from surrounding soil constantly.
What shows up at the tap
Algae and bacterial growth increase with humidity, heat and organic sediment deposits accumulating on walls and floor.
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
How do we access a tank buried beneath old wooden floorboards?
We carefully lift the flooring and clear soil and debris around the tank. Then we pump out water, lift sediment from the base and pressure-wash the walls.
Why does water in Harat Al Mazloum discolour faster than newer areas?
Coastal salt humidity deposits salts and iron on the tank. Old pipework made from weak materials causes continuous rust and contamination.
Does sterilization solve the salty taste problem in the water?
Treatment cleans the tank and removes sediment but does not fix old piping. Complete solution may require replacing the pipe network.
How often should a tank be sterilized per year in an old quarter?
Two or three times yearly due to humidity and salt spray. Priority timing is after summer heat and peak humidity months.
Do tanks in traditional souqs need different treatment than house tanks?
Yes. Souqs use more water and foul faster. Treatment requires more frequent cycles and deeper wall scrubbing.
Is tank sterilization alone enough if the pipes are corroded or contaminated?
No. Sterilization keeps the tank clean but corroded pipes degrade water during delivery. Pipe inspection is essential before final sign-off.
How much does water tank sterilization in Harat Al Mazloum 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 Mazloum.
