Water tank sterilization in Al Mahamid Jeddah
Al Mahamid grew informally on Jeddah's eastern edge beside the Old Makkah Road. Buildings are low-rise and many streets remain unpaved; old drainage creates a humid environment. Tanks here face contamination from shallow soil and groundwater seepage.
-
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 Mahamid
Buildings here were built in the 1960s and 1970s without coordinated planning, and tanks sit close to ground level where they risk groundwater seepage. The method is set out in full on what Water tank sterilization involves.
Old drainage and contaminated soil
Drainage in Al Mahamid is very old and sometimes broken. Foul water seeps into soil and ground-level tanks lie close to surface, exposed to direct contamination.
Shallow unprotected tanks
Most tanks here are buried shallowly or sit directly above ground without solid bases. Small cracks in the tank allow contaminated water and insects to enter.
Shallow groundwater is a continuous contamination source
Groundwater in Al Mahamid sits very close to surface and carries salts and pollutants. Rainy periods raise the water table and multiply contamination risk.
Al Mahamid on the map
Al Mahamid sits about 4.5 km from Umm Al Salam and about 5.5 km from Al Harazat.
Open in Google MapsWhat we read inside the tank before anything starts
An unplanned residential area on Jeddah's eastern fringe beside the Old Makkah Road, accessed mainly from Harazat Road. Construction is informal, streets are narrow and drainage is very old.
Sediment on the floor
Silt and mud accumulate on the floor because the old drainage network leaks contaminated water around the subfloor tank.
The slime film on the wall
Algae and brown residue grow rapidly because groundwater is laden with minerals and nutrients.
Light and heat
Pipes hold silt and sediment because the groundwater is very cloudy and particle-heavy.
The lining and any cracking
Moisture and heat together create ideal conditions for bacterial bloom, especially in shallow tanks exposed to sun.
The lid and the openings
Biological and chemical contamination develops around unprotected tanks due to continuous soil seepage.
What shows up at the tap
Bacteria and viruses appear when taps run after rainy periods.
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.
The character of Al Mahamid
Mixed district: shops at street level with homes above them
Low-rise informal areas mean tanks are often simple and poorly sealed. Treatment must account for basic construction and verify the tank is not already leaking through its base before sterilization begins.
Questions about this district
Why does tank water turn cloudy during the rainy season in Al Mahamid?
Shallow groundwater rises in wet months. Unprotected tanks are exposed to contamination from wet soil and silt.
Is a below-ground tank in Al Mahamid more dangerous than a roof tank?
Yes, a subfloor tank sits closer to contaminated soil and groundwater. But an unshaded roof tank faces heat and pathogenic bloom.
Is sterilization enough or must the tank structure be improved too?
Sterilization removes current contamination but if the tank is cracked or unsealed, contamination returns. Repair or replacement may be needed.
Does cloudy water in Al Mahamid signal a drainage system failure?
The cloudiness may come from silt and sediment in the tank itself, or from drainage seepage. Technical inspection determines the cause.
Should a tank be sterilized before the rainy season?
Yes, sterilization just before the rains is wise. It reduces the risk of contamination from rising groundwater.
Is line flushing enough if contaminated soil surrounds the tank?
Line flushing clears the pipes. But if the tank itself leaks contaminated water, the tank sealing must be repaired first.
How much does water tank sterilization in Al Mahamid 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 Mahamid.
