Water tank sterilization in Al Harah Al Janubiyah Jeddah
Al Harah Al Janubiyah is Thuwal's southern quarter where simple residential houses open onto empty land and farms. Tanks here are exposed to wind-blown dust and sand from neighbouring vacant ground. Cleaning requires special care because of heavy sand deposits and earth accumulation on tank walls.

Why the job is different in Al Harah Al Janubiyah
Homes here are surrounded by low-density agricultural land and open space, and wind carries dust and sand into tanks that remain partially open. The method is set out in full on how we approach Water tank sterilization.
Dust and sand from neighbouring vacant ground
The quarter is surrounded by empty land and unbuilt fields. Strong winds carry fine dust and sand onto exposed rooftop tanks. Sand deposits accumulate faster than in dense quarters.
Simple popular housing and basic tanks
Homes here are modest and tanks are old and poorly sealed. Small gaps and cracks allow dust and small insects to enter.
Surrounding farms increase moisture and salinity
Neighbouring farms provide natural moisture and air from the nearby sea carries salt. This increases tank wall corrosion and builds up salt deposits and algae.
The character of Al Harah Al Janubiyah
Mixed district: shops at street level with homes above them
An open-edge residential quarter means tanks exposed to wind and dust. Treatment must first seal gaps and cracks, then deep clean sand and salt deposits that enter from the air.
What we read inside the tank before anything starts
The southern part of coastal Thuwal, simple popular housing on inner streets with open edges facing farms and empty ground. The quarter slopes south toward Dhahban and Jeddah.
Sediment on the floor
Sand sediment removal from the floor is essential because wind from vacant ground carries fine sand that settles rapidly on tank floor.
The slime film on the wall
Pressure washing walls removes salt layers and brown algae that grow quickly in the damp coastal environment.
Light and heat
Sterilizing lines from the furthest tap is necessary because fine sand enters pipework and blocks small openings.
The lining and any cracking
Moisture from farms and the nearby sea increases fungal and algal growth on exposed tank walls.
The lid and the openings
A basic tank may need repair of small openings and cracks before cleaning to prevent new dust entry.
What shows up at the tap
Orange or brown cloudiness in water may mean metal oxide and salt buildup, and sterilization works after these deposits are 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 sand deposits from vacant ground affect cleaning?
Yes. Heavy sand deposits need longer pressure wash cycles. Fine sand easily penetrates soft walls and pipework.
Why are partially open tanks here harder to sterilize?
Unsealed tanks allow continuous dust and insect entry. Sterilization is less effective if the tank remains partially open.
Does sea salt in the air affect the tank?
Yes. Salt accelerates metal corrosion and builds salt deposits on internal walls. Cleaning must remove these salt layers.
How often should a tank be cleaned if surrounded by empty ground?
Three times yearly is better than twice because dust and sand enter constantly from the air.
Is pressure washing enough for heavy sand deposits?
High-pressure washing is necessary but may take longer. Some fine sand may need specialist cleaning agents.
Does sterilization stop new dust entering from the air?
Sterilization kills bacteria but does not prevent dust entry. Sealing the tank and closing cracks must happen before sterilization.
How much does water tank sterilization in Al Harah Al Janubiyah 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 Al Harah Al Janubiyah.
