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

Al Aziziyah is a densely packed district in central Jeddah, with apartment blocks stacked above ground floor shops, restaurants, popular markets and Tihama Park. The dust here is dark from main roads and commercial activity, and tanks may hold coloured sediment from a mix of diesel soot, grease and salt combined. A team here must move quickly and safely on congested rooftops and understand the complexity of mixed residential and commercial pipework.
Tanks above shops and restaurants in Al Aziziyah hold thick dark coloured sediment from a mixture of diesel, grease and salt, and require a strong team that knows how to work safely on narrow crowded rooftops. For the method itself, see what water tank cleaning involves.
Al Aziziyah sits on busy main roads choked with trucks and cars, and dark dust is laden with diesel soot and oil. This enters the tank through ventilation gaps and pipes, leaving a black oily film on the walls. Deep cleaning is essential, and grease-cutting disinfectant must be strong enough to remove both oil residue and the bacteria it harbours.
Apartment blocks built over shops mean complex pipework: mixed water and drainage lines, with one tank possibly serving multiple flats and different flats potentially connected to different tanks. Pre-drainage inspection is essential because we must know all connections and never allow our drainage to flow accidentally into shop pipework below.
Al Aziziyah is extremely dense, with buildings very close together. Rooftops are narrow and tanks may be very tightly spaced or surrounded by other tanks. A team must move with extreme care without disturbing neighbouring residents or accidentally draining water onto adjacent buildings.
Al Aziziyah sits north east of central Jeddah, dense and tightly built, with main roads running through it, popular markets and closely spaced apartment blocks. Dust entering from main roads is dark and oily, and salt and grease accumulation in tanks is faster than in quieter areas.
In the dense district on the main road, the tank may hold thick dark sediment from a mixture of diesel, salt and grease, so we inspect closely with strong light and measure deposit depth.
Draining a tank surrounded by other buildings requires safe disposal without running black oily water onto adjacent buildings, so we manage drainage with extreme care.
Sediment removal from the floor is difficult here because dark oily deposits are thick and matted; we work with force and care to remove all of it.
Scrubbing the walls takes considerable time because grease and diesel are rooted deep in the surface, and we use strong approved scrubbing compound safe for all tank types.
Strong disinfection is essential because the polluted main road environment and commercial activity 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 soot residue, no oily smell and no diesel 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.
Mixed district: shops at street level with homes above them
The mixed commercial and residential character of Al Aziziyah means tanks sit above shops, restaurants and markets alongside residential flats, all on a heavily trafficked main road.
Pumps to clear sludge, scrubbing to remove biofilm, and disinfectant meant for potable storage.
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.
Central Jeddah is the old heart of the city: Al Balad with its coral stone houses, and the dense apartment quarters around it with shops beneath the flats. Floors here are often terrazzo or older ceramic tile, worn smooth and easily stained by cooking grease that drifts up from the street. Older kitchens and bathrooms carry heavy scale on taps and around drains, and pipework in the older blocks leaves rust marks in basins. Rugs and curtains take on the fine black dust of the main roads, so they need washing more often than elsewhere.
We provide these in Al Aziziyah too, and more than one can share a single visit.
