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

Prince Fawaz South is a densely built district close to the port and the heavy truck routes that run between the industrial city and the coast. The dust here is darker and oilier than elsewhere in Jeddah, a mix of diesel soot and workshop grit. Tank sediment accumulates as black oily matter that does not wash away with water alone. This requires cleaning that targets industrial pollutants before they enter the drinking water supply.
Dark diesel soot and workshop dust settle on exposed rooftop tanks, and the sediment here is not just grey but black and oily, requiring vigorous scrubbing and repeated rinsing. For the method itself, see our water tank cleaning service in detail.
The proximity to heavy truck routes and the industrial area means dust falling on tanks is mixed with diesel soot and grease, not simply airborne sand. These black oily deposits need firm manual scrubbing to remove, and they do not dissolve in water or respond to light brushing.
South Jeddah is close to the sea and humidity is high, so soot clings more stubbornly to tank walls. The combination of moisture and oily pollutants accelerates formation of hard black layers that resist rinsing.
Many apartment blocks in the district are older, with shared tanks that have served multiple households for years without regular cleaning. Sediment has built up in hard layers that are difficult and time consuming to break down.

The team inspects and assesses the proportion of black and oily sediment, and plans the cleaning according to the degree of industrial pollution.
Full drainage takes time because oily deposits are heavy and may have stuck to the floor over years.
Sediment vacuuming focuses on removing the black oily layer from floor and walls, with particular attention to corners where soot accumulates.
Scrubbing needs force to clear the oily black coatings from tank walls, particularly around areas exposed directly to outside air.
Disinfection follows complete removal of oily deposits, and the agent helps prevent bacterial regrowth in a polluted environment.
Final rinsing takes extra time to clear all traces of soot and oily matter, and the lid is checked to ensure it seals completely.
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.
Prince Fawaz South sits about 1 km from Prince Fawaz North and about 1 km from Al Shifa.

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.
South Jeddah runs from the port and the industrial city down towards Al Khumrah, and homes here sit between the sea and the heavy goods roads. The dust is darker and oilier than in the north, a mix of diesel soot and workshop grit, and it clings to net curtains, window sills and the tops of kitchen cupboards. Floors in the older low rise housing are often plain cement or ceramic tile that darkens where soot is walked in. Humidity from the coast adds mildew in bathrooms and a musty smell in stored fabrics.
We provide these in Prince Fawaz South too, and more than one can share a single visit.
