Water tank sterilization in Al Taqwa Makkah
Al Taqwa is a new quarter on the southern hillside along the old Yemen road, with government housing schemes and buildings under construction. Tanks here are usually new but receive water from an old mixed network. Dust and sediment from new and old pipes contaminate water in the first months of use.
-
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 Al Taqwa
Tanks here are newly built but receive water from very old mixed network pipes. Dust and sediment from new pipes and old sources contaminate water in the early months of use. The method is set out in full on the full Water tank sterilization page.
New tanks receiving water from old pipes
New buildings in Al Taqwa have modern tanks but connect to very old network pipes. These old pipes carry years of accumulated sediment, and when connected to the new tank, they contaminate it quickly.
Construction dust and debris from new pipes
Building and installation work leaves dust and particles trapped in new pipes. In the first year of use, these particles settle in the tank causing cloudiness and odour.
Housing projects need multiple tanks
Large residential compounds in Al Taqwa may have a main tank and branch tanks in each building. Sterilization requires coordination across multiple tanks and their connecting lines.
The character of Al Taqwa
New development: ongoing construction and vacant plots between the homes
Al Taqwa is a new development quarter with modern buildings and new tanks, but the key difference is that main network pipes are very old. Sterilization must focus on contamination arising from old pipes and construction sediment, not long-term buildup.
What we read inside the tank before anything starts
A newly developed quarter on the southern slopes of Al Misfalah around Qawz Al Nakasah, with housing projects, new buildings and popular markets threaded by Al Taqwa Street. It lies on the old Yemen road after slum clearance.
Sediment on the floor
Fine dust and particles from new pipes and construction settle quickly on the tank floor.
The slime film on the wall
Old main network pipes introduce mineral sediments and aged algae into the new tank.
Light and heat
Distribution lines from the main tank to branch tanks in each building may contain construction sediment.
The lining and any cracking
Heat and humidity in Al Taqwa are moderate compared to the city centre but bacterial growth remains rapid in contaminated water.
The lid and the openings
The primary contamination source is the junction between old network pipes and the new tank, where pressure drops and sediments settle.
What shows up at the tap
Signs of contamination include metallic taste, slight cloudiness or odour of earth and rust.
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 Misfalah Sub-Municipality
Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.
Questions about this district
Why did new Al Taqwa tanks become contaminated on first use?
They connect to old pipes from the main network and the new pipes contain construction sediment from assembly and installation.
Does construction dust decline over time?
Yes, but may take months. Early sterilization and good flushing reduce this period.
What is the difference between sterilizing a new and old tank?
A new tank may need strong mechanical washing to remove construction dust before sterilization. An old tank may need deeper sterilization because sediment is aged and harder to remove.
Does one housing scheme need one tank or multiple?
Large schemes typically have a main tank and branch tanks in each building. Each tank requires separate sterilization.
When should a new building tank be sterilized, before or after occupancy?
Best practice is immediately after building completion and before occupancy to avoid residents using contaminated water. Then sterilize again after the first month of use.
Does water from the old network affect water quality after sterilization?
Sterilization kills bacteria and pathogens but does not remove mineral sediment from old pipes. If old pipes remain, mineral contamination may return over time.
How much does water tank sterilization in Al Taqwa 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 Al Taqwa.
