Water tank sterilization in Al Zumurrud Jeddah
Al Zumurrud is a modern coastal district on the Red Sea with high-rise apartment blocks, new villas and large residential developments. Water here passes through high and ground tanks and is exposed to sea salt, coastal moisture and intense heat. Regular sterilization cuts algal growth and sediment build-up, which accumulates rapidly in the coastal climate.

How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush

-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Zumurrud
Most buildings and villas in Al Zumurrud were built in the last twenty years. Tanks are modern but subjected to high water pressure due to proximity to the sea and high elevation of some buildings. The method is set out in full on what Water tank sterilization involves.
High tanks in residential towers and hotels
Large residential projects and hotels in Al Zumurrud rely on very tall rooftop tanks. These are exposed to intense sun heat and coastal moisture, which accelerates algal and mineral sediment formation.
Humidity and salt affect water quality
The coastal climate in Al Zumurrud is very humid and salt seeps into tanks through condensation. Modern villas and apartment buildings require regular sterilization to prevent mineral deposit and marine algae accumulation.
Pump systems and long piping need regular flushing
Large developments in Al Zumurrud have long pipe runs from high tanks to individual units. These pipes trap silica and calcium deposits, and sterilization must include flushing from the furthest outlet.
The character of Al Zumurrud
Coastal area: high humidity and salt air through the year
Al Zumurrud is a modern coastal district with villas and new apartment buildings. Most tanks are recent plastic or exposed reinforced concrete. Treatment focuses on removing algae and salt films with high-pressure washing and deep flushing of long piping runs.
What we read inside the tank before anything starts
A modern coastal district in northern Jeddah on the Red Sea with recent villas and apartment buildings, residential and commercial plots and mixed use developments. It is bordered by the sea to the west, Al Lulu to the south and Al Sawari to the east.
Sediment on the floor
Mineral sediment accumulates rapidly on tank floors because of hard water and seawater salt.
The slime film on the wall
Green and brown algae grow on the walls of high exposed tanks facing sun and heat.
Light and heat
Black sludge and sediment collect in tank corners and beneath inlet pipes.
The lining and any cracking
Coastal humidity and salt cause wall corrosion and create a thin biofilm layer requiring pressure washing.
The lid and the openings
Small cracks in concrete trap water and sediment and become sources of repeated contamination.
What shows up at the tap
Water lines from high tanks to horizontal runs contain mineral deposits requiring deep flushing.
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 Dhahban Sub-Municipality
Dhahban sub municipality is the northern coastal strip of Jeddah, running from the north bank of Sharm Obhur up to the old village of Dhahban and Salman Bay. Its districts are recently built, with owner occupied villas and apartments, beach resorts and chalets on the shore, and land subdivisions still being developed. Nearness to the sea keeps humidity high all year, irrigated lawns in villas, resorts and district parks hold water, Wadi Obhur and the vacant plots between buildings give rodents and reptiles shelter, and the old fishing village of Dhahban gives the far north a rural edge.
Questions about this district
Why do algae grow faster in Al Zumurrud tanks than in inland areas?
Coastal humidity, intense heat and direct sunlight accelerate algal growth. High exposed tanks receive more sun and heat than buried or ground-level tanks.
Is annual tank sterilization once a year enough in a coastal climate?
It may not be. Coastal areas may need twice-yearly sterilization because humidity and salt speed up contamination.
What is the difference between sediment in coastal tanks versus inland tanks?
Coastal sediment contains more salt and mineral compounds, and algae grow faster due to higher moisture.
Are modern plastic tanks in Al Zumurrud easier to sterilize?
Yes, plastic is smooth and does not trap deposits like concrete. However, high-pressure washing is still needed to remove algae films from the interior.
How often must piping be flushed of sediment in large projects?
Piping is flushed with each sterilization, especially long runs and high risers that trap sediment.
Does salt entering the tank from coastal air affect water safety?
Yes, condensation introduces salt and mineral compounds into the tank. Sterilization must remove these deposits from walls and the tank floor.
How much does water tank sterilization in Al Zumurrud 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 Zumurrud.
