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

Al Safhah is a simple residential neighbourhood in east Jeddah near Asfan and the University of Jeddah, one of a cluster of small quarters with modest housing. Road dust enters the tank easily from the dry air, and grey sediment builds faster than in enclosed areas. Stale water carries road dust and the surrounding dryness together.
Tanks here carry grey sediment from road dust, and need regular cleaning because dust enters easily through air vents. For the method itself, see what water tank cleaning involves.
Al Safhah is close to University of Jeddah Road and Asfan Road, main roads with heavy traffic and dust. The dry air of east Jeddah carries fine and coarse road dust. This dust enters the tank through air vents and settles on the base as a grey layer.
East Jeddah is far from the sea and the air is dry. Dry dust floats easily and enters the tank without resistance, unlike humid coastal air which weighs dust down slightly. Grey sediment may accumulate quickly in Al Safhah.
Small neighbourhoods may have unpaved or narrow old roads. Sand and gravel enter the tank with dust. Suction may find layers of sand alongside natural sediment.

Tank inspection in Al Safhah reveals a thick grey layer of road dust and sand on the base.
Full draining removes grey heavy water loaded with sand and dust from the roads.
Sediment suction carefully removes sand, gravel and fine dust to avoid entering the pipes.
Wall scrubbing removes any emerging algae and a fine dust layer that may be clinging to surfaces.
Disinfection kills bacteria and microorganisms from humidity and stagnation.
Final rinsing repeats several times to remove the last sand and dust particles and ensure water clarity.
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.

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.
East Jeddah lies furthest from the sea and closest to the open ground and hills beyond the ring roads, so the air is drier and the dust is coarser and paler than on the coast. It comes in under doors and settles on every flat surface overnight, making sofas, mattresses and curtains the heaviest part of the routine. Floors are mostly ceramic tile in the apartment districts and marble in the villa areas, both scratched by grit that is mopped rather than swept. Roof tank water leaves a grey film of sediment in baths and basins.
We provide these in Al Safhah too, and more than one can share a single visit.
