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

Petromin is a popular quarter in south Jeddah, named after the refinery next door. Construction is simple and tanks may be small or retrofitted by residents. The quarter is undergoing replanning with new building alongside older housing, so tanks vary in age and condition.
Tanks here are very mixed: some are new from modern construction, some are very old from the original housing. Tank size may be small because the housing is modest, or there may be more than one tank on the same property. For the method itself, see our water tank cleaning service in detail.
Simple popular housing may have very small tanks, five hundred to a thousand litres. Cleaning requires care to avoid damage, and suction may be more delicate than on larger tanks to prevent wall stress.
Petromin has new building next to old housing. One property may have a tank from the nineteen eighties, and beside it a new apartment building with a modern tank. Each needs different handling.
On some properties in Petromin there are two tanks: one for drinking, one for general use, or a rooftop tank plus a basement tank. We need to identify the number and separate them before booking.
A popular quarter in south Jeddah beside the Jeddah oil refinery from which it takes its name, part of the old quarantine area. Low income housing built up to a main street facing the refinery fence was included in the city's slum clearance and replanning programme.
Tank inspection in Petromin requires entry and access to the roof or basement to confirm tank size and condition.
Full draining may produce cloudy water if the tank has been neglected, and we may need extra drainage capacity.
Sediment suction on small tanks is more careful to avoid damage to thin metal walls.
Hand scrubbing of walls removes biofilm and algae from tank surfaces, especially in tight corners.
Disinfection before rinsing ensures all bacteria and microorganisms are killed.
Final rinsing repeats until water runs clear, and the lid and pipework are inspected.
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.
Petromin lies between the Jeddah Refinery and Al Falah Road, with Al Nujoom Roundabout as an inner landmark. We reach the tanks through narrow streets, using the Jeddah Refinery and the roundabout as main navigation points.
We provide these in Petromin too, and more than one can share a single visit.
