Water tank sterilization in Jarwal Makkah
Jarwal is a dense quarter north west of the Sacred Mosque where old Makkan family houses have become budget hotels and seasonal pilgrim lodgings. Tanks here serve a constant stream of guests so they never rest, pipes are weak and contaminated from years of wear, and Jabal Qaiqaan rises to the east bringing dust and minerals in the wind and water.

Why the job is different in Jarwal
Tanks are under continuous pressure from heavy consumption by permanent and seasonal guests, and contamination accumulates faster than in quieter residential areas. The method is set out in full on Water tank sterilization in detail.
Budget hotel and apartment tanks serving large seasonal guest numbers
Budget hotels and apartment blocks in Jarwal host thousands of Hajj and Umrah pilgrims each season. Tanks drain rapidly and fresh water enters daily, sediment deposits accumulate with each new intake.
Old contaminated pipes from decades of intensive use
Pipes in Jarwal are very old and carry mineral and bacterial sediment from years of continuous operation. Modern pipes exist only in a few large hotels; the rest rely on pipes from the 1960s and 1970s.
Jabal Qaiqaan sends dust and minerals through the air
Jabal Qaiqaan rises directly above Jarwal to the east and winds carry fine dust and salts to ventilation holes and tank covers. Incoming water carries metal particles and salts from ancient soil deposits.
Landmarks of Jarwal
Access to Jarwal runs via Umm Al Qura Road and Al Taysir Road as main thoroughfares, with the historic Bir Tuwa well and commercial buildings as landmark anchors defining the district.

What we read inside the tank before anything starts
A densely occupied residential quarter north west of the Sacred Mosque with seasonal hotels and apartment blocks, Jabal Qaiqaan rising on the east, Al Amerah and Al Quran Road from the south, and Umm Al Qura Road and Al Taysir from the western side.
Sediment on the floor
Heavy mineral salts settle quickly at the tank base and in remote corners.
The slime film on the wall
Bacteria and algae live in pipes and on tank walls because water is warm and use is intensive.
Light and heat
Water intake from old pipes is laden with mineral and bacterial sediment accumulated from years of use.
The lining and any cracking
Humidity is very high because hotels and apartment blocks consume water intensively and leaks are common from old pipes.
The lid and the openings
The tank may contain heavy silt and salt deposits on the floor that do not dissolve easily, requiring mechanical removal and high pressure.
What shows up at the tap
Post-sterilization inspection includes taste and odour testing from multiple taps and water colour assessment from first and last outlets.
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 Ghazza Sub-Municipality
Al Ghazza sub municipality wraps around the north and west of the Grand Mosque, from Al Shamiyah, Al Qararah and Shaib Amir round to Jarwal and Al Taysir. Large tracts were cleared for the northern expansion and the Rua Al Haram scheme, leaving excavated ground and open construction sites beside ageing blocks that now serve as dense seasonal lodgings in Jarwal and Al Taysir. Old flood paths still fall from Jabal Qaiqaan and Jabal Khandamah towards the mosque, and markets and eateries crowd Al Masjid Al Haram Road and Umm Al Qura Road.
Questions about this district
Do seasonal hotel tanks need more frequent sterilization than permanent hotels?
Yes. Heavy rapid use brings more contamination sources. Seasonal hotels need sterilization before each Hajj and Umrah season.
Is the water in Jarwal harder than in other quarters?
Yes. Water here carries more mineral salts than other areas due to Jabal Qaiqaan and ancient soil.
Does tank sterilization improve the taste and smell of water?
Sterilization removes bacteria that cause strange odours. But heavy salts may remain and need additional treatment such as purification.
Do budget hotels need special sterilization cycles before the season?
Yes. Seasonal hotels need complete cleaning before opening to pilgrims. Pipes may have been dry for months before the season.
How many times should a budget hotel tank be sterilized in a year?
During Hajj and Umrah season it may need sterilization every month or two. Outside season, one annual sterilization may suffice.
Do dirty pipes affect the sterilization outcome?
Yes, heavily contaminated pipes retaminate the tank quickly after sterilization. Complete pipe flushing may be needed alongside tank cleaning.
How much does water tank sterilization in Jarwal 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 Jarwal.
