Water tank sterilization in Harat Al Kanadirah Jeddah
Harat Al Kanadirah in Thuwal depends on water brought in by tankers from outside the town, which is then stored in household tanks for extended periods. The quarter is mixed, with older popular houses beside newer concrete homes, and tanks accumulate sediment and algae due to saline water and high coastal humidity.

Why the job is different in Harat Al Kanadirah
Residents receive water by tanker and store it in household tanks, and the saline water mixed with coastal humidity causes rapid sediment and algae buildup. The method is set out in full on Water tank sterilization in detail.
Long-term storage tanks for trucked-in water
Residents here bring water in by tanker and store it in elevated or ground-level tanks for weeks at a time. Saline water reacts with tank walls and leaves white mineral deposits and brown algae.
Older houses with confined small tanks
Traditional homes here have small tanks squeezed into corners or under roofs, hard to reach and prone to rapid fouling. Coastal humidity accelerates algae formation.
Coastal humidity and salinity speed contamination
Thuwal sits on the Red Sea coast and humidity is high year-round. Salt and moisture corrode tank walls and promote algae film growth rapidly.
The character of Harat Al Kanadirah
Mixed district: shops at street level with homes above them
The quarter is mixed: older popular houses with small confined tanks sit beside modern concrete homes with larger tanks. Treatment strategy adapts to tank size and accessibility, but all tanks face accelerated fouling from coastal salinity.
What we read inside the tank before anything starts
A residential quarter in Thuwal on the northern Red Sea coast of Jeddah governorate, bounded by Wadi Thuwal to the south and the new Jeddah-Madinah road to the east, with the university to the north, drawing all its water from external tankers.
Sediment on the floor
Saline water and coastal humidity cause rapid buildup of white mineral and sediment deposits on the tank floor and walls.
The slime film on the wall
Bacteria and brown or black algae flourish on walls due to humidity, light penetration and standing saline water.
Light and heat
Old confined tanks in popular homes make it hard to reach corners and far edges.
The lining and any cracking
Coastal humidity and salt corrode tank walls, creating small holes and stress cracks.
The lid and the openings
Sediment collects quickly on the floor because tanker water is mineral-rich and saline.
What shows up at the tap
Remote taps and lines far from the tank may hold more sediment and algae due to stagnant water residence time.
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
Why do deposits build up faster in Thuwal tanks than in other areas?
Tanker water contains mineral sediment and is saline. High coastal humidity then accelerates algae growth on the walls.
Is sterilization alone enough if the tank is years old?
No. Sediment must first be lifted from the floor and walls pressure-washed until algae film is gone. Only then does the sterilizing agent work.
What causes blackening of tank walls in the older homes?
Algae and bacteria grow fast in saline water under high humidity. Old tanks also have cracks that admit light and air.
How often must tanks be sterilized in Thuwal given the salt and humidity?
At least twice yearly. Coastal humidity and saline water accelerate fouling far faster than inland areas.
Do the small confined tanks in old houses need a different approach?
Yes. Narrow tanks make entry and washing difficult. We use specialist equipment and focus hard on scrubbing algae from corners.
Does white sediment buildup mean the last sterilization failed?
Not necessarily. It may be natural mineral accumulation from saline water. Mineral deposits need harder scrubbing than freshwater sediment does.
How much does water tank sterilization in Harat Al Kanadirah 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 Kanadirah.
