Water tank sterilization in Khadra Makkah
Khadra is a new residential district on King Faisal Road, and apartment blocks are rising rapidly on a young grid. Water tanks in these new buildings receive water from the main distribution network, but the tanks themselves accumulate sediment and biofilm rapidly because the buildings are new and tanks are often delivered unclean. Sterilization means full emptying and pressure washing to remove silt and bacteria from tank walls and floor.
-
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 Khadra
New residents in the apartment blocks notice water colour changes and odd smells within weeks of moving in, indicating rapid bacterial growth in unclean tanks. The method is set out in full on how we approach Water tank sterilization.
New tanks never cleaned before handover
Most new buildings are delivered with tanks that have never undergone industrial cleaning. Silt and construction debris from initial pipework remain on the floor and walls.
High water pressure accelerates biofilm formation
The main distribution network supplies water at constant high pressure. This drives minerals and impurities into the tank, where they accumulate and form biofilm rapidly.
High temperature and sun exposure speed bacterial growth
Khadra is open and hot, and tanks on new building roofs face direct sun exposure. This speeds bacterial and algal growth in standing water.
Landmarks of Khadra
Khadra spans King Faisal Road as the main axis between Al Muaysim centre and Al Sharai, with the Haram boundary as a natural western limit. Key access and boundary landmarks mark the district:
- King Faisal Road
- Al Arifi Mosque
- Hajz Al Sharai Mosque
- Sheikh Musaad bin Mastour Al Lihyani Mosque
- Salaty Market and Bakery
What we read inside the tank before anything starts
A newly developed residential quarter on King Faisal Road between Al Muaysim and Al Sharai, straddling the Haram boundary and enlarged by the former Sharai scheme seven. Apartment buildings, commercial centres and street-level shops are rising together, though municipal services and schools lag behind the pace of construction.
Sediment on the floor
Mineral deposits and silt accumulate on floor and walls from impurities in the main network and debris from recent construction.
The slime film on the wall
Biofilm grows rapidly on walls and floor because temperature is high and tanks face direct roof exposure.
Light and heat
Supply lines from tank to units need complete flushing to remove bacteria and residual disinfectant.
The lining and any cracking
Internal moisture is high due to evaporation under heat, accelerating biofilm growth.
The lid and the openings
Biofilm accumulates on tank surfaces, especially in corners and joints where water slows.
What shows up at the tap
Cloudy or discoloured water signals advanced biofilm activity, and sterilization must be followed by comprehensive line flushing.
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 water colour change so quickly in new tanks?
New tanks contain silt and construction debris from initial pipework. Pressure and heat accelerate biofilm formation, which changes colour and smell.
Is one sterilization enough or do tanks need regular cycles?
Initial sterilization removes silt and bacteria. After that, tanks should be disinfected every six months to a year depending on incoming water quality.
What causes sediment buildup on the tank floor?
Minerals and impurities from the distribution network settle on the floor due to pressure and gravity. New pipework and fittings also release particles into the initial water.
Is sterilization safe for children and sick residents after treatment?
Yes, after full sterilization and line flushing, water is completely safe. We allow adequate time for any remaining disinfectant to clear.
Do individual apartment tanks need different treatment than shared building tanks?
Individual tanks are smaller but require the same steps: emptying, pressure washing, sterilization and flushing.
How many inspections confirm that a tank is fully clean?
We inspect after emptying, after pressure washing, and after sterilization and flushing. Three inspections usually confirm the tank is clean.
How much does water tank sterilization in Khadra 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 Khadra.
