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

Al Hamdaniyah is a dense residential sprawl east of the airport, with tall apartment blocks, villas and major commercial streets along Al Hamdaniyah Street and Al Masurah Street. Tanks here are elevated to serve multiple floors, so water moves fast but leaves thick lime deposits from the very hard water that the area sits on.
Tanks here are elevated on buildings of varying heights and serve multiple floors, so scale deposits from hard water build up thickly and unevenly, requiring powerful suction and deep scrubbing. For the method itself, see our water tank cleaning service in detail.
In Al Hamdaniyah, the tank sits on a roof or upper floor and pumps water down through several storeys. Changing pressure leaves scale deposits uneven on the walls. Drainage needs a planned approach because the tank may be difficult to reach and the roof risky to work on.
Al Hamdaniyah sits on limestone. The water is hard and deposits accumulate rapidly on every surface. Powerful suction and deep scrubbing are needed to remove these solid crusts from walls and floor.
Al Masurah Street and Al Hamdaniyah Street are major market streets with constant traffic and commercial dust. Grit enters the tank through a loose lid or through gaps around fittings. Disinfection matters more here than in residential quarters.
A dense urban spread east of King Abdulaziz Airport, with hypermarkets and apartment buildings, villas and major commercial streets, bordered by Al Haramain Road on the west and serving tens of thousands of residents.
In Al Hamdaniyah we inspect the tank on the roof or top floor first, checking access, safety and the lid condition before we begin draining.
Draining takes longer because the tank is elevated and water may need a powerful pump to empty it completely.
Scale deposits here are thick limestone crusts from hard water, requiring repeated powerful suction followed by vigorous manual scrubbing.
Scrubbing the walls and floor removes brown algae and biofilm built up from the hard water over months of accumulation.
Disinfection is especially important here because major markets nearby deposit dust and grime that enters through a worn lid.
Final rinse and inspection confirm water clarity and test the lid and filter screen before we refill and sign off.
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
Mixed district here means elevated tanks on apartment building roofs amid large commercial markets. Dust and grime from the busy streets enter easily through poorly sealed lids. The very hard water leaves stubborn, thick deposits.
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.
Tanks in Al Hamdaniyah often sit on rooftops near Al Masurah Street or Al Hamdaniyah Street, and reaching them needs knowledge of how each building is laid out. We coordinate with you at the time to identify the safest and most direct route to the tank.
We provide these in Al Hamdaniyah too, and more than one can share a single visit.
