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

Abu Jaalah is a small residential quarter in south Jeddah with mid rise apartment blocks, and tanks here are shared among several flats per building. Continuous property turnover means new residents who do not know the tank's history and may not know each other, making coordination difficult. The tank may go uncleaned for years because no single owner takes responsibility, and decision making requires agreement among people with conflicting interests.
Flats in Abu Jaalah change hands regularly due to property activity, and shared tanks often go neglected because no resident knows when it was last cleaned or takes ownership of the problem. For the method itself, see what water tank cleaning involves.
One building may have ten or more flats, each owned or rented by a different person. No one owns the tank alone, and no one takes responsibility for cleaning it. Group decisions are difficult, and the tank may remain dirty for years because collective action is hard to organise.
Abu Jaalah is active in flat sales and rentals, and new residents may not know each other yet. A cleaning request may come from a single resident suffering from cloudy water, whilst other households do not know there is a problem or do not want to pay.
Tanks on the roofs of closely packed buildings collect street dust and grit continuously. Roofs may not be well covered, and tanks may sit in open air with loose or damaged lids.
A simple neighbourhood centred on Safad Street and Technical College Street, with flat terrain and closely packed buildings. Rooftop tanks collect street dust and neighbourhood grit continuously from the surrounding area.
Tank checked before we start: in apartment buildings, we need permission from owners or building management. We assess location, size and initial condition from outside first.
Old water drained out: neglected apartment tanks may hold very old, black water. Safe rapid evacuation prevents spillage onto flats below.
Sediment vacuumed from the bottom: neglected tanks often have thick black sludge of algae and bacteria on the floor. Deep powerful suction removes all of it.
Walls and floor scrubbed: walls may be black with algae and grime. Thorough manual scrubbing takes longer in neglected tanks than in regularly maintained ones.
Interior surfaces disinfected: strong disinfectant kills accumulated bacteria and fungi. Very old tanks may require stronger treatment.
Final rinse and lid check: multiple rinse passes may be needed to clear all black water. The cover is inspected carefully, as old tanks often have large openings or damaged seals.
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.
Abu Jaalah lies near Safad Street and Technical College Street, and identifying buildings and their rooftop tanks requires knowledge of narrow side streets and the closely packed urban layout.
We provide these in Abu Jaalah too, and more than one can share a single visit.
