The right gear for drinking water
Pumps to clear sludge, scrubbing to remove biofilm, and disinfectant meant for potable storage.

Al Jamiah is a dense, established apartment district in south Jeddah, with tall apartment blocks tightly stacked above shops, restaurants and small markets. Tanks here sit high on crowded rooftops and may hold complex mixed sediment: black dust from heavy traffic and diesel soot, sand from open ground inland, and salt from relative proximity to the coast. A team must move quickly and safely on extremely crowded rooftops and understand shared tank systems.
Tanks in Al Jamiah rise high on crowded old apartment block rooftops and may hold a mixture of black dust, sand and salt combined, requiring a strong team that knows how to work safely on very tight rooftops. For the method itself, see our water tank cleaning service in detail.
Al Jamiah is near busy heavy-use roads choked with trucks, and black oily dust enters the tank and leaves a black film on walls and floor. This dust mixes with salt from relative coastal proximity, so the sediment is coloured and oily. Deep cleaning and strong grease-cutting disinfectant are essential.
Tanks in Al Jamiah sit on rooftops of very large buildings housing many residents, and there may be more than one tank on the same roof. A team must move fast and with extreme care without disturbing residents, and the rooftop space is very tight. Coordination with you before arrival is essential.
Al Jamiah faces both heavy road traffic and coastal salt air at once, so the tank experiences both diesel soot and sea salt simultaneously. The sediment is mixed and complex, with no single solution to remove it. We need careful assessment first to identify the main contaminant, then specialised cleaning to address both.
Al Jamiah sits in south Jeddah on Old Makkah Road near Al Jamiah Roundabout and Andalusia Hospital. It has very high density, closely spaced apartment blocks with crowded rooftops, busy main roads and relative proximity to the coast and port.
In a dense established district in south Jeddah, the tank may hold mixed coloured sediment from soot, salt and sand combined, so we inspect closely with strong light and measure deposit depth.
Draining a tank above huge occupied apartment blocks requires safe disposal without running discoloured water onto other buildings, so we manage drainage with extreme care.
Sediment removal from the floor is difficult here because mixed sediment is compacted; we work with force and care to remove it all.
Scrubbing the walls takes considerable time because mixed contamination is rooted deep, and we use strong approved scrubbing compound safe for all surfaces.
Strong disinfection is essential because mixed contamination and high density have created diverse bacteria, so we use certified disinfectant approved for drinking water.
The final rinse takes a very long time because we must ensure no colour, smell or off-taste remains before handover.
The supply into the tank is shut and the tank is drained completely.
The sludge on the floor is scooped and pumped out first.
The biofilm on the walls is physically scrubbed off.
With the walls and floor clean, a disinfectant made for drinking-water storage is applied and given time to act on every surface.
The disinfectant and any loosened residue are rinsed down and pumped out, so the first tank of water after us is not carrying it.
We check the cover seal and inlet before refilling, so dust and insects stay out, then start the refill while you watch it run clear.
Apartment district: residential blocks, repeated floors and shared entrances
The dense residential character in Al Jamiah means tall apartment blocks on tight rooftops with tanks that may serve dozens of flats. Location between heavy traffic routes and relative coastal proximity means complex multi-source contamination.

We send a team, not one person, so a tank is drained, cleaned, disinfected and refilled in a single visit rather than left open for days.
We look at the lid seal and inlet, because a tank that got dirty fast usually has a way in.
Nothing is closed until the tank is refilling and you have seen the water run clean.

The commitment is simple enough to actually keep: we do not leave until the tank is disinfected, refilling, and you have seen it for yourself.
Al Jamiah Roundabout and Andalusia Hospital mark the location clearly within this busy dense district, and when we schedule your appointment we use these major landmarks to direct our team quickly to the correct building.
We provide these in Al Jamiah too, and more than one can share a single visit.
