Water tank sterilization in Tarwiyah Makkah
Tarwiyah is a new residential quarter east of Al Sharai between Al Sharai and Al Rashidiyah, with new apartment blocks, villas and residential plots on a regular grid. Tanks here are new but groundwater in Jeddah carries heavy minerals and forms thick sediment layers quickly. Regular cleaning and sterilization is essential because tanks fill from local wells beneath the district.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
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 Tarwiyah
Most buildings were constructed within the past five years and tanks have filled from local wells; the groundwater carries visible mineral sediment. The method is set out in full on our Water tank sterilization service.
New tanks and shallow wells
Tanks in the villas and new apartment blocks draw from local wells beneath the district. Shallow wells provide water but carry silt and red clay from local soil. Sediment accumulates rapidly at the tank base.
New water network and clean pipelines
Pipelines and tanks are relatively new but sediment and bacteria begin to grow from the first filling. Exposed rooftop tanks face sun, air pollution and bird droppings. Sterilization is necessary every one to two years.
Ongoing development and new construction
The quarter is still under development and new foundations and excavations disturb the ground. Soil particles and contaminants enter tanks during construction. Tanks in newly occupied buildings need sterilization before residents move in.
Landmarks of Tarwiyah
Tarwiyah is bounded to the north east by King Abdulaziz Sports City and to the east by the channel of Wadi Mudarraja, with Al Sawwat Mosque within the district serving as a navigation landmark to define the service zone.

What we read inside the tank before anything starts
A new residential development quarter south of King Faisal Road, between Al Sharai and Al Rashidiyah, with apartment buildings and villas on low ground. It is bounded to the north east by King Abdulaziz Sports City and to the east by the channel of Wadi Mudarraja.
Sediment on the floor
Silt and iron from local wells settle at the base forming thick layers that need high-pressure cleaning.
The slime film on the wall
Algae and bacteria grow on exposed rooftop tank walls due to sun and moisture.
Light and heat
Relatively new pipelines still accumulate sediment from the tank, reducing flow and causing deposits.
The lining and any cracking
Moisture and sun heat on rooftops encourage algae and bacterial growth.
The lid and the openings
Underground tanks are protected but sediment builds up at the base and in internal pipelines.
What shows up at the tap
New tanks in apartment blocks and villas need sterilization before first filling because construction leaves dust and mineral particles.
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 Al Sharai Sub-Municipality
Al Sharai is the eastern growth front of Makkah along King Faisal Road and the Taif road. Settled quarters sit beside recently renamed schemes where plots are still vacant and buildings are going up, so construction sites, fill and open excavations lie next to occupied homes. Wadi channels such as Wadi Mudarraja, Wadi Al Sharai and Wadi Al Mughammas carry flash floods after rain and dry out to damp silt, while dust blows off the open hills. Roadside shops, restaurants and warehouses line the Taif road, and to the east the area shades into villages, palm farms and springs.
Questions about this district
Why does a new tank need sterilization if it is brand new?
New tanks fill from local wells that carry sediment and minerals. Bacteria and algae begin to grow from the first filling even if the tank looks clean.
Is groundwater in Tarwiyah contaminated?
It is not dangerously contaminated but it carries silt and iron from local soil. This sediment settles at the base and encourages bacterial growth.
How often should a tank be sterilized per year?
New and sun-exposed tanks need sterilization every one to two years. Closed underground tanks may need it less often.
Does sterilization remove all sediment?
Sterilization kills microbes but does not remove chemical sediment. We need high-pressure washing before sterilization to remove sediment from the base and walls.
Are closed underground tanks better than open ones?
Yes, underground tanks protect from sun, air pollution and birds. But sediment and bacteria still grow in them and they need regular sterilization.
Does tank sterilization affect resident health?
Sterilization with approved agents is safe and necessary. It removes harmful bacteria and algae that can cause health issues or foul taste and odour.
How much does water tank sterilization in Tarwiyah 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 Tarwiyah.
