Water tank sterilization in Umm Al Salam Jeddah
Umm Al Salam is a mixed residential quarter on the Old Makkah Road with apartment buildings, residential blocks and small shops. Tanks here accumulate sediment and algae due to high moisture, intense heat and heavy daily use. Sterilization requires thorough floor and wall cleaning followed by careful application of the sterilizing agent.

Why the job is different in Umm Al Salam
Most residential buildings are four to six storeys, and the tanks on roofs face direct sunlight and high temperatures year-round. The method is set out in full on Water tank sterilization in detail.
Thick sediment in base of simple residential tanks
Tanks in modest apartment buildings accumulate sediment quickly because water pressure is low and water stands for long periods. The base becomes coated with mineral deposits and green algae to a depth of several centimetres.
High roof temperatures accelerate algal and bacterial growth
Tanks in Umm Al Salam sit in direct sun on rooftops; temperatures exceed 50 degrees Celsius. Heat and light drive rapid algal reproduction and an oily film forms on tank walls.
Heavy use reduces water quality in storage
Dense residential buildings consume large volumes of water continuously, day and night. The tank has no time for natural settling and sediment mixes with drinking water constantly.
The character of Umm Al Salam
Mixed district: shops at street level with homes above them
Umm Al Salam is a mixed quarter with simple residential blocks and a dense population. Tanks are usually on roofs with poor covers, exposed to sun, heat and dust. Treatment requires thorough sediment and algal removal before sterilization, because local climate conditions accelerate contamination growth.
What we read inside the tank before anything starts
A mixed residential quarter in south-eastern Jeddah on the Old Makkah Road, bordered by Al Harazat and Al Mahamid toward the main highway to Makkah, with the Umm Al Salam Health Centre, mosques and low-rise residential streets.
Sediment on the floor
Water entering the tank carries salts and minerals from pipes and earth; these settle at the base and form thick white or grey layers.
The slime film on the wall
Green algae and organic growth develop on walls and floor when the tank receives direct sunlight and intense heat from rooftop exposure.
Light and heat
Water lines from tank to taps may hold dried sediment and organic debris requiring separate pressure flushing.
The lining and any cracking
High moisture and heat inside the tank and around foundations create ideal conditions for microbial and anaerobic bacterial growth.
The lid and the openings
Settled sediment at the base may contain heavy metals and pollutants from the water network and surrounding earth.
What shows up at the tap
Sulphur smell and darkened water indicate accumulated organic matter and bottom bacteria requiring deep pressure cleaning and full sterilization.
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 Umm Al Salam Sub-Municipality
The Umm Al Salam sub municipality covers the east and south east of Jeddah along the Old Makkah Road and the Haramain Road. It pairs recently planned districts such as Al Wahah, Al Nakhil and Al Shuruq with popular districts that grew outside formal planning, including Al Harazat, Al Mahamid and Umm Al Salam. The older areas have ageing drainage, unpaved streets and vacant plots where building waste collects, conditions that suit rodents, cockroaches and ants. The newer areas are ringed by half built subdivisions and open excavations.
Questions about this district
Why does water in an Umm Al Salam tank discolour within days of sterilization?
If old sediment was not cleaned thoroughly or organic debris remains at the tank base, algae begin to reproduce again. Thorough pressure-cleaning of the base is critical in this quarter.
Does sediment build up faster in Umm Al Salam than other areas?
Yes, because tanks face high heat and direct light, and heavy use shortens natural settling time. You may need sterilization every six months rather than annually.
Is the water entering Umm Al Salam tanks contaminated by external pipes?
External pipes may carry some contamination, but pressure-cleaning the tank itself removes most accumulated sediment. Cleaning the supply lines from source to tank may be a useful extra step.
Is sterilization alone enough or do we need extra cleaning during the year?
Once-yearly sterilization may not suffice in Umm Al Salam due to heat and heavy use. Inspection every six months and additional cleaning helps extend cleanliness periods.
Do green algae come from inside the tank or from incoming water?
Algae grow from light, heat and nitrogen already present in stored water. Dark or sealed tanks significantly reduce reproduction.
How much sediment and algae is removed in one Umm Al Salam clean?
Thorough pressure-cleaning removes most sediment and algae if done correctly. Small algal traces may remain if embedded in walls, but the sterilizing agent kills remaining cells.
How much does water tank sterilization in Umm Al Salam 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 Umm Al Salam.
