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

Al Balad is the historic heart of Jeddah, a UNESCO World Heritage district of coral stone houses and wooden rawashin lattice. The tanks here are old or mounted in century-old buildings, and the pipework is ageing brass and iron. Corrosion leaves visible rust marks, and sediment from the ancient pipework settles heavily on the tank floor. We drain the tank fully, vacuum the brown rust deposits and debris, scrub the walls thoroughly to remove mineral scale and sediment, disinfect with drinking-water safe products, and rinse repeatedly until the water runs clear again.
The old brass and iron pipes leave visible rust stains in basins and bathroom tiles, and the tank itself collects these iron particles from the corroding pipework that feeds it. For the method itself, see the full water tank cleaning page.
Corroded copper and iron in the old pipework release fine rust particles that travel in the water column and settle on the tank floor. Water drawn immediately after opening the taps sometimes runs brown or cloudy with iron oxide as sediment is stirred up.
Settlement and movement in century-old foundations crack pipes occasionally, allowing fine dust and cement particles from the building fabric to enter the tank along with the water. The sediment here is more diverse in composition than in modern districts.
Heritage buildings have become crammed apartment houses, and the old tanks are mounted in confined spaces between walls. Accessing and cleaning them requires care and careful planning to avoid disturbing old structures.
The historic commercial heart of Jeddah with a dense old city fabric of coral limestone tower houses and wooden lattice screens, narrow lanes and ageing services and pipework throughout.
Tank inspection in old Al Balad focuses on the condition of ancient brass and iron pipework and the brown rust deposits visible on the tank walls and floor.
Draining water from a tank in a historic building requires care with narrow pipework and confined spaces surrounding the tank installation.
Sediment vacuumed from the floor is predominantly brown rust and mineral deposits from corroded copper and iron pipes feeding the tank.
Wall scrubbing targets brown staining, scale and rust marks, repeated several times to ensure complete removal of the mineral buildup.
Disinfection uses drinking water safe products to kill bacteria that colonise the sediment and corrosion deposits accumulated over decades.
Final rinsing is repeated until the water runs completely clear and free of brown discolouration from iron oxide.
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.
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.
Al Balad is the historic quarter centred on Nassif House and Al Shafi'i Mosque, and your tank sits in one of the narrow old souq lanes where access requires knowledge of the tight pathways of the old city.
We provide these in Al Balad too, and more than one can share a single visit.
