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

Al Adl is a small mixed district in south east Jeddah between Old Makkah Road and the Jeddah Makkah Expressway, with a hospital, mosque and busy commercial axes. Tanks here serve shops and flats together, and black dust from vehicles on the expressways settles on everything. The home sits between the sea and the heavy goods traffic, neither truly quiet.
The dust is darker and oilier than in the north, a mix of diesel soot and workshop grit that leaves a black mark in the water and sticks to everything. For the method itself, see our guide to water tank cleaning.
The Makkah Expressway carries heavy diesel trucks all day, and black dust enters the district from every direction. Tanks on rooftops collect diesel soot directly from the traffic flow.
Shops and restaurants on the commercial streets draw a lot of water and cooking fats may enter the drains. The tank serves busy commercial premises and residential flats at the same time.
Coastal humidity mixes with diesel soot and creates sticky residue on the walls. Cleaning needs more effort to remove the oily layer that forms.
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.
Initial inspection reveals a black layer of soot and dust on the tank floor and walls with oily residue marks.
Full drainage is essential because soot clings hard and needs thorough flushing to remove.
Vacuuming focuses on removing the black soot layer from the floor and oily sediment residue.
Manual scrubbing is strong because soot is sticky and clings; emphasis on upper walls where it settles.
Disinfection is very strong because of soot, oils and humidity that all encourage bacterial growth.
The final check confirms the lid is tight and protected from black soot dust returning.
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
In a mixed district in south Jeddah like Al Adl, the tank serves both commercial shops and residential flats on a busy heavy traffic road. Black soot and oily dust accumulate fast because of the expressway.
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.
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 Al Adl too, and more than one can share a single visit.
