Water tank sterilization in An Nawwariyah Makkah
An Nawwariyah is a relatively modern northwest district near the main Madinah road, a mix of villas, apartment blocks and wide undeveloped tracts. Water comes from the main network but pressure is unstable and tanks range from old to new. Water quality is affected by organic growth and sediment accumulation during periods of outage or low pressure.

Why the job is different in An Nawwariyah
Residents in An Nawwariyah are mixed between modern villa owners and older apartment dwellers, with tanks ranging from new to old and water resources unstable. The method is set out in full on how we approach Water tank sterilization.
Modern villas and old apartment blocks with different tank sizes and types
The district mixes modern villas with large fibreglass tanks and older apartment buildings with small iron tanks. Different tank types require different treatment approaches.
Unstable water pressure causes dirt to be sucked into the tank
The main Madinah road passes near the district and pressure fluctuates. When pressure drops, dirt and moisture can be drawn from pipes into the tank.
Wadi An Nawwariyah and high humidity accelerate bacterial growth
The district lies near Wadi An Nawwariyah and humidity is high especially in winter and spring. Bacteria and algae grow rapidly in the moist environment.
Landmarks of An Nawwariyah
Access to An Nawwariyah is via the main northern Madinah road, with Mohammed Saleh Basharahil Hospital as the central landmark. The district is bounded by Wadi An Nawwariyah to the east and the tomb of Maymunah bint Al Harith to the south, defining the service zone.

What we read inside the tank before anything starts
A northwest district near the main Madinah road, mixed with villas and apartment blocks and open land, home to Mohammed Saleh Basharahil Hospital, a pilgrim grouping centre, An Nawwariyah Park and the tomb of Maymunah bint Al Harith. It is bounded by Wadi An Nawwariyah to the east.
Sediment on the floor
Dirt and sediment enter the tank when main network pressure drops sharply.
The slime film on the wall
Brown and green algae grow rapidly on tank walls, especially in older exposed tanks.
Light and heat
Full pipeline flushing is essential because air may have entered pipes during outages.
The lining and any cracking
High humidity from Wadi An Nawwariyah and proximity to open land accelerates bacterial growth.
The lid and the openings
Iron sediment from old metal tanks accumulates on the floor quickly.
What shows up at the tap
Cloudiness and metallic taste appear after water outages or sharp pressure drops.
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 Umrah Sub-Municipality
Al Umrah sub municipality covers the north west of Makkah along the Madinah road and the old Jeddah road, from At Tanim and Masjid Aisha to An Nawwariyah. Its districts are the city's newest, villas and apartment blocks raised on wide schemes where large tracts in Al Umrah Al Jadidah, Al Fayha and Al Buhayrat remain vacant or under construction. Wadi Saraf and Wadi At Tanim run through it and rainwater gathers on unfinished schemes, ihram shops, restaurants and coach stops along the Madinah road serve a constant flow of pilgrims, and villas fill Al Hamra and Umm Al Jud.
Questions about this district
Why is our water sometimes cloudy after periods of outage?
When water stops, air enters pipes and dirt accumulates. When water returns, dirt is pushed into the tank.
Do old tanks in apartment blocks need different treatment than villas?
Yes. Old iron tanks may contain rust deposits. Fibreglass is cleaner but needs protection from light and heat.
How do we deal with high humidity and algae growth?
High humidity means faster algae growth. Regular sterilization and good tank insulation are essential.
Does sterilizing the tank solve the problem of low pressure?
No. Sterilization removes bacteria and algae. Low pressure is a separate issue requiring intervention from the water company.
Should villa and apartment building tanks be sterilized the same way?
No. Villas with large tanks need deeper cleaning. Apartment buildings with small tanks may need faster turnaround.
What is the difference between preventive and active sterilization?
Regular sterilization prevents bacteria from building up. Active sterilization treats the problem after symptoms appear.
How much does water tank sterilization in An Nawwariyah 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 An Nawwariyah.
