Water tank sterilization in Ghulail Jeddah
Ghulail is an old popular quarter in south Jeddah next to the former Al Mahjar quarantine district. The quarter was blighted by failed drainage, uncollected refuse and severely fouled tanks. The entire district has been cleared under the South Jeddah redevelopment programme and its land now awaits rebuilding. Old household tanks were never serviced and have been left abandoned in the rubble.
-
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 Ghulail
Buildings and tanks that were demolished were fifty years old or more, with sediment and deposits in tanks so thick they were mixed with sand and gravel. The method is set out in full on Water tank sterilization in detail.
Abandoned tanks exposed in rubble without covers
Old tanks left uncovered in demolition rubble after buildings came down. Dust, debris, animals and sewage seep in, causing comprehensive contamination.
Failed sewage system and continuous seepage
Broken old pipes leaked sewage into tank walls and floors. Moisture and foul odour indicate sewage has mixed with drinking water.
High humidity and organic decay
High moisture, sewage failure and complete neglect created perfect conditions for bacteria and fungal growth. Tanks contain rotting organic matter.
The character of Ghulail
New development: ongoing construction and vacant plots between the homes
A district under complete demolition means old tanks will not be used in the future. Sterilization is undertaken more for safe disposal documentation than for long-term preservation.
What we read inside the tank before anything starts
An old popular quarter in south Jeddah beside the former Al Mahjar quarantine zone, with narrow worn streets plagued by sewage failure and accumulating refuse. The district has been completely demolished under the South Jeddah redevelopment programme and the land now awaits reconstruction.
Sediment on the floor
Heavy deposits of sand, gravel and silt accumulated on the floor over years without cleaning and direct exposure to pollutants.
The slime film on the wall
Algae, fungi and bacterial colonies spread across walls and floor because humidity was very high and organic matter abundant.
Light and heat
Sewage lines and pipes are thoroughly contaminated and likely mixed with human waste.
The lining and any cracking
Moisture is very high because sewage infrastructure failed and contaminated water sat in soil around the tank.
The lid and the openings
Main accumulation lies on the tank floor, corners and pipes-zones that cannot be easily accessed for cleaning.
What shows up at the tap
Visual inspection and odour reveal comprehensive contamination: water is black, grey or emits very strong foul smell.
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 Jamiah Sub-Municipality
Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.
Questions about this district
Can old Ghulail tanks be sterilized or must they be replaced?
If tank structure is sound it can be sterilized, but demolition and replacement is better. Old tanks here are not worth preserving.
Why are Ghulail tanks more contaminated than quarters with functioning services?
Sewage infrastructure failed for years and tanks were never cleaned. The quarter was under-resourced and maintenance never occurred.
What drives the high cost of sterilizing a Ghulail tank?
Heavy sediment, organic contaminants and sand and gravel require intensive manual removal and very deep cleaning.
Does sewage mixing make sterilization unsafe?
If sewage contamination is suspected, sterilization alone is insufficient and the tank should be replaced.
Do abandoned tanks in rubble need cleaning before reuse?
Yes, thorough cleaning is essential. Years of exposure and external contamination demand complete sterilization.
Should old Ghulail tanks be reused in new construction or replaced?
Old tanks are not recommended for new building. Purchasing a new tank is better than attempting to restore the old one.
How much does water tank sterilization in Ghulail 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 Ghulail.
