Water tank sterilization in Al Murjan Jeddah
Al Murjan is a small coastal district on the north corniche, with villas, apartment buildings and gated compounds directly overlooking the waterfront. Water tanks here accumulate sea salt, marine residue and algae from proximity to the sea. Sterilization must account for the coastal environment's direct impact on water quality and require deep cleaning of salt deposits and biofilm.
-
Potable-rated materials

-
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 Murjan
Buildings here are relatively modern and tanks face very high humidity with direct exposure to sea winds and salt spray. The method is set out in full on what Water tank sterilization involves.
Tanks exposed to sea wind and salt spray
Villas and buildings on the waterfront face salt-laden sea breezes and high humidity. Rooftop tanks receive continuous saltwater mist, leaving salt deposits on interior and exterior walls.
Algae and biofilm from the coastal environment
High humidity and moderate heat on the coast create ideal conditions for algae and bacteria growth. Biofilms form rapidly on tank walls and contaminate water supplies.
Easy access and regular monitoring
Villas and apartment buildings in Al Murjan have clear tank access points, and residents here monitor water quality closely because they maintain high health and hygiene standards.
Landmarks of Al Murjan
Access to tanks in Al Murjan runs via Al Murjan Street and the north corniche road. Al Murjan Mall and rooftop tank sites are clear landmark anchors in the district.

What we read inside the tank before anything starts
A low-density coastal district on the north corniche between King Abdulaziz Road and the sea, west of Al Basatin. Its main axes are Al Murjan Street and the north corniche road, with Al Murjan Mall serving local retail.
Sediment on the floor
White and yellow salt deposits accumulate on floor and walls due to direct sea spray and high humidity exposure.
The slime film on the wall
Green algae and biofilm grow rapidly on walls and floors due to light and very high moisture.
Light and heat
Cracks and joints in tank walls provide entry routes for seawater and suspended salts.
The lining and any cracking
Continuous humidity from the sea prevents tank drying and promotes microbial growth and bacterial slime.
The lid and the openings
Cavities and old gaps in the tank floor trap heavy sediment and salt deposits.
What shows up at the tap
Marine microorganisms and fine algae become visible after periods of high humidity and direct sea exposure.
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 Obhur Sub-Municipality
Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.
Questions about this district
Does sea salt leave permanent deposits inside the tank?
Yes, salt forms white and yellowish layers on walls and floor. Pressure washing removes most of it, but repeated treatment may be needed if exposure continues.
Why do algae and biofilm grow faster in Al Murjan than inland districts?
The coast provides very high humidity, moderate temperature and natural light. These conditions are ideal for algae and aerobic bacteria growth.
Is annual tank sterilization enough for Al Murjan?
It may not be sufficient due to the coastal environment. We recommend sterilization every six months at minimum to keep water free of salt and algae.
Does tank sterilization protect against future contamination from sea spray?
Sterilization removes current pollutants but does not prevent future contamination. Good ventilation and a tight tank cover reduce salt and moisture ingress.
How do we handle heavy salt deposits at the tank floor?
We use mechanical suction to remove floor deposits, then pressure-wash the floor and walls to remove accumulated layers.
Do villas and apartment buildings need different treatment approaches?
Yes. Villas have smaller tanks and roofs exposed directly, while apartment buildings may have larger tanks that are relatively protected.
How much does water tank sterilization in Al Murjan 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 Murjan.
