Water tank sterilization in Rashidiyah Makkah
Rashidiyah is a planned villa quarter far from the city centre, where each villa has its own deep underground tank and private pipes. The long distance from the main water station means low, slow pressure, and water travels through long pipes crossing Wadi Mudarraja. Tanks here are large and collect heavy sediment from the long journey.
-
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 Rashidiyah
Tanks here are large and relatively modern, but the long distance from the main water station causes low pressure and heavy sediment accumulation. The method is set out in full on Water tank sterilization in detail.
Very deep underground tanks in each villa
Each villa in Rashidiyah has an underground tank buried very deep, often two metres or more. Sediment collects on the floor and cleaning needs strong suction and large water drainage.
Long pipes accumulate sediment during transit
Pipes from the water station to Rashidiyah are very long, and low pressure means water moves slowly. Fine sediment travels with the water and settles in the tank.
Wadi Mudarraja affects incoming water quality
Wadi Mudarraja runs through the district and soil lies close to pipes. Seasonal moisture and small floods may cause dirt infiltration into pipes.
The character of Rashidiyah
Villa district: private plots, gardens and a boundary wall to every house
A villa quarter means deep, large tanks for each separate villa, and long distance from the main station means low pressure and heavy sediment. Cleaning needs strong suction equipment and large water drainage. Sterilization needs longer flushing than villas closer to the city.
What we read inside the tank before anything starts
The villa quarter in far east Makkah, bounded to the north by the Makkah to Taif expressway and on its western edge by King Abdulaziz Sports City. Wadi Mudarraja runs through it, and villas are laid out on a planned grid with Rashidiyah Park, a health centre, schools and private clinics.
Sediment on the floor
Heavy sediment accumulates on the very deep tank floor, especially iron and calcium from long pipes.
The slime film on the wall
Biofilms grow due to low pressure and slow water flow. Anaerobic bacteria thrive.
Light and heat
Long pipes from the station to the villa allow bacteria and sediment to settle along the route.
The lining and any cracking
Moisture from Wadi Mudarraja and close soil may allow dirt and bacteria to enter pipes.
The lid and the openings
Concrete tanks are relatively old and may contain fine cracks harbouring bacteria.
What shows up at the tap
Resistant bacteria multiply in the anaerobic environment caused by low pressure and slow flow.
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 take so long to reach villas in Rashidiyah?
Long distance from the main station and low pressure mean water moves slowly through very long pipes.
Does heavy sediment in Rashidiyah tanks come from the pipes or the tank itself?
Both. Water carries sediment from the station and long pipes, and the tank collects all of it on its floor.
Does Wadi Mudarraja cause tank problems?
It may, especially in autumn and winter during small floods. Moisture can cause dirt infiltration into pipes.
How does sterilizing a Rashidiyah tank differ from areas closer to the Haram?
Rashidiyah is farther so pressure is lower and sediment heavier, so sterilization needs longer flushing and stronger pressure.
How often should a villa tank in Rashidiyah be sterilized?
At least every six months, and twice yearly if incoming water quality is poor.
Is tank cleaning in Rashidiyah more expensive than villas closer to the city?
Yes, because tanks are deeper, sediment is heavier and drainage takes longer.
How much does water tank sterilization in Rashidiyah 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 Rashidiyah.
