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

Al Mawaddah is a small residential district in east Jeddah within a cluster of simple neighbouring quarters, where popular housing predominates. Tanks here may be old and shared across a rooftop, grey sediment from the road and coarse dust accumulates rapidly. A team must understand the challenges of old pipework, shared tank systems and a dry environment.
Tanks here may be old and inlet pipes may be corroded, so water entering may carry grey sediment from old pipes, and deposits accumulate quickly on the floor. For the method itself, see our guide to water tank cleaning.
Old simple housing and worn pipes mean water entering the tank may carry rust particles from the lines or gravel from old excavations. Grey sediment accumulates quickly on the floor, and water after drainage may run cloudy. Cleaning the tank alone may not solve the problem if the pipes themselves are contaminated.
In simple residential clusters there may be one tank serving several small adjacent homes, with complex inlet and outlet pipework. Pre-drainage inspection is essential because we must know which homes are connected and never cut water to one inadvertently.
The area is dry and far from the sea, and dust is coarser and paler than on the coast. Dust and fine gravel enter the tank easily through weak gaps in the lid. Heavy grey sediment settles quickly on the floor and needs strong suction and deep scrubbing to remove.
Al Mawaddah lies in east Jeddah toward Asfan close to University of Jeddah Road, a simple residential area in a group of small adjacent quarters. The air is drier and the dust coarser and paler than on the coast, infiltrating under doors and settling on every surface overnight.
In a simple residential district in east Jeddah, the tank may hold thick grey sediment from old pipes, so we inspect closely with strong light and measure deposit depth.
Draining a tank that serves multiple houses requires coordination with you and the other households to set a suitable time.
Sediment removal from the floor takes considerable time because grey deposits are heavy and gravel is compacted deep.
Scrubbing the walls is more straightforward here because sediment is not sticky like algae, but the floor and corners need hard scrubbing.
Tank disinfection is essential here because limited humidity and old pipework have allowed bacteria to thrive, so we use strong approved disinfectant.
The final rinse takes time because we must ensure no sand or cloudiness 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 simple dry environment in Al Mawaddah means the tank faces coarse dust and gravel from the road and corroded old pipes. Grey sediment and rust stains are the primary problems, not algae or salt or grease.
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.
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 Mawaddah too, and more than one can share a single visit.
