Water tank sterilization in Al Taawun Jeddah
Al Taawun is a new-development district on the southern fringe of Jeddah along the Al Laith road, with new housing schemes from the Ministry of Housing, Rawdat Al Taawun villas and open land. The tanks are relatively new but the groundwater in this location carries high salt and mineral content, and sediment accumulates rapidly in the tank bottom.
-
Potable-rated materials

Why the job is different in Al Taawun
Tanks here are newer than central Jeddah but the groundwater beneath the district carries high concentrations of calcium and salt. The method is set out in full on what Water tank sterilization involves.
High-salinity and mineral-rich groundwater
Water drawn from boreholes in Al Taawun carries salts, iron and heavy minerals. Deposits settle rapidly at the tank base and form a brown sediment layer quickly.
New tanks and model villas
Most tanks here were built with new housing schemes and are tightly sealed. But internal tank walls accumulate an oily film and fine algae from static water.
High consumption in villas and government projects
Villas have larger tanks and use heavy water volumes for irrigation and daily use. Government schemes contain multiple units and shared tanks with high consumption load.
The character of Al Taawun
New development: ongoing construction and vacant plots between the homes
New-development areas have modern sealed tanks but groundwater is highly saline. Sterilization must focus on removing salts and algae from tank walls and flushing the full network, as contaminants can return quickly in high-mineral water.
What we read inside the tank before anything starts
A new-development zone on the southern edge of Jeddah east of Al Khumrah and south of Al Sanabil along the Jeddah to Al Laith road, with Al Hussein ibn Ali Street and government housing schemes and vacant land.
Sediment on the floor
Brown sediment and sludge settle rapidly at the base because groundwater carries high salt and heavy mineral load.
The slime film on the wall
Oily film and algae coat the internal tank walls because static salty water creates ideal conditions for fine algae.
Light and heat
Small cracks in the tank floor may cause slow seepage into soil, and inspection must cover the floor closely.
The lining and any cracking
Moisture is high at the base and corners because standing water and decomposing minerals sustain continuous wetness.
The lid and the openings
Deep sediment settles at the lowest point, and washing must lift sediment from the base with force.
What shows up at the tap
Bacteria and fine algae reappear quickly after sterilization if flushing is incomplete, and lines may remain contaminated.
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 South Sub-Municipality
The South sub municipality runs from the edge of Old Makkah Road down to Al Khumrah and the southern corniche. Dense residential districts sit beside new subdivisions such as Al Sanabil and Al Taawun, warehouse fringes such as Al Saruriyah and Al Sarawat, and an old seaside settlement at Al Quzayn. Open stormwater channels cross the housing, and the warehouses, the vegetable and livestock markets and the nearby Islamic Port and Industrial City give pests shelter, food and year round humidity. Pressure is greatest in the older quarters, where drainage networks are ageing.
Questions about this district
Why does sediment accumulate so fast in an Al Taawun tank?
Groundwater in this zone carries high dissolved salt and mineral load. These minerals settle and accumulate rapidly at the tank base, especially if the tank remains static for long periods.
Does sterilizing a new tank differ from an old one?
Yes, new tanks are better sealed but need deeper washing to remove salts and fine algae that grow quickly in static new water.
How often must we sterilize tanks here?
Salty water speeds contamination, so sterilization must be more frequent than in other areas-every three months instead of four or five.
Are algae from groundwater dangerous?
Algae and fine bacteria grow quickly in salty static water, and sterilization must reach tank walls with force to remove them completely.
Does tank washing alone suffice or do we need line treatment too?
Washing alone is not enough, as salts and algae may remain in pipes and taps. We must flush lines from the furthest outlet.
Do government projects have special sterilization needs?
Yes, large shared tanks need deep washing and full network flushing because consumption load is very high and water sits longer.
How much does water tank sterilization in Al Taawun 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 Taawun.
