- Rinsing the tank fully to remove all trace of the solution before refilling
- Returning the tank to use after confirming no trace of the sanitising agent remains
From your call to refilling
- 1
Tell us about the tank
Call or message us on WhatsApp and tell us about your tank type, what you notice in the water, and whether it was cleaned recently.

Emptying and cleaning the tank
Before sanitising the tank must be fully clean and free of sediment, as the sanitising agent cannot work on a surface covered by a layer of dirt.
- 3
Treating the inner surface
The sanitising solution is applied to the walls, base and lid of the tank and left long enough for it to act on the germs clinging to the surface.
- 4
Rinsing and refilling
Once sanitising is done the tank is rinsed thoroughly to remove any trace of the solution, then refilled and returned to use.

The service in Al Ahsa
Tanks in homes in a city like Al Ahsa are exposed to contamination from salty groundwater, dust and dirt that enter during filling and distribution. After the tank is drained and mechanically cleaned, a thin layer of sediment and salt remains on the base and inner walls, and this layer harbours bacteria and mould. The technician visits to inspect the tank inside and out and chooses the sanitising treatment that suits its condition. The treatment removes suspended matter, salt and microorganisms to achieve clean water.
Al Ahsa is a city in Al-Ahsa governorate in the Eastern Province, close to As Saifa District, Ayn Najm District and Al Muhammadiyah District.
Groundwater in Al Ahsa carries high salt content, so sanitising after cleaning removes the salt that settles on the tank walls.

Questions about Tank sanitising in Al Ahsa
Cleaning removes visible sediment, algae and dirt from the walls and base. Sanitising follows it and treats the bacteria and germs that cling to the surface after rinsing. The two steps are different, and the second cannot replace the first or come before it.
Not necessarily every time, but sanitising is advisable when the water still smells or looks different after cleaning, when a long time has passed since the last sanitising, or when algae growth was found inside. In these cases cleaning alone does not fully treat the tank.
While the sanitising solution is applied and during the treatment period water from the tank should not be used. After rinsing and refilling the water returns to normal use. It helps to let the household know in advance so they can prepare for a short break in supply.
If the smell comes from bacteria or algae on the tank walls, sanitising after cleaning treats the source. But if it comes from elsewhere, such as the pipes or the water source itself, sanitising alone will not remove it. That is why describing the smell and when it appears helps when you call us.
The principle is the same in both cases: the inner surface is cleaned first, then treated with the sanitising solution and rinsed well. The difference is in how the inner walls are reached and in the size and shape of the tank. This affects how the job is done but not what sanitising is for.
Cleaning removes visible sediment, but bacteria, salt and mould remain on the walls and base. Sanitising removes what you cannot see and ensures drinking water is safe.
Tell them the tank size, depth and material, whether the water changes colour or smell between cleanings, and if there are visible leaks or cracks, and send a photo on WhatsApp if you can.
