Clean and Safe water is a basic necessity and the core of healthcare, sanitation, and even comfort. Throughout the UAE, the water tanks play a major role in storing and distributing water in homes, residential buildings, and commercial properties. Still, many people do not understand the importance of water tank cleaning. Apart from these things, there are dirt, sediment, algae, bacteria, and other contaminants that can build up inside the tank and affect the quality and cause serious health risks.
So, how do you know when your water tank needs cleaning? Sky MAK Technical Services tells you the key warning signs, risks, and best practices to stay proactive and protect your water supply below.
1. Dust particles in water
One of the clearest indications that your water tank requires cleaning is water looks dirty. Whenever you fill a glass or bucket, if you see any particles, rust flakes, or floating debris, it is a clear indication that sediment has built up in the tank.
If the tanks are not cleaned properly, the sediments settle at the bottom, and this totally spoils the water quality every time the tank is refilled.
2. Unpleasant smell or taste
Clean water does not smell or taste good. If your water gives off a metallic, musty, or rotten odour, or if its taste is peculiar, it could be the result of bacterial growth or algae inside the tank. The very hot UAE environment promotes the growth of microbes, particularly in the tanks that are not cleaned regularly.
It is a sign that must not be ignored as it can lead to stomach troubles, skin irritation and other health issues, especially for children and old people.
3. Change in Water Colour
Discoloured water is yet another primary indicator and a strong warning sign. The appearance of yellowish, brown, greenish, or cloudy water could be due to many reasons, like rust, algae, or suspended impurities in the tank. Algae’s colour is usually green, which is displayed in the water; the tanks need immediate cleaning.
As such, any colour change in the water should be considered an emergency, and professional tank cleaning should be done.
4. Slime or Algae Inside the Tank

If you see layers of slime on the walls or at the bottom, when inspecting your tank, that’s a clear sign of biofilm formation. Bacteria and pathogens form biofilm, and their removal requires not only cleaning but also proper disinfection.
Algae becomes a problem in tanks that are either not well-designed or have no proper lids. Periodic cleaning is all that is needed to maintain the tank in a hygienic state and prevent contamination.
5. Frequent Plumbing or Filter Issues
Are water filters usually clogging more frequently? Is debris blocking the taps? These plumbing troubles can be a concealed indication that there is dirt in your water tank. The dirt and contaminants, when passing through the system, filter and strain pipes, cutting down water flow, hence increasing maintenance costs.
Getting the water tank cleaned saves the plumbing fixtures and filtration systems.
6. It’s Been More Than 6 Months Since the Last Cleaning
The majority of health and safety guidelines suggest water tank cleaning at least every six months. In places such as apartments, villas, restaurants, hospitals, and labour accommodations where water is used a lot, cleaning might be done even more often.
If you can’t remember when your tank was last cleaned, it is probably time to make an appointment.
7. Health Issues Among Occupants
In many cases, water contamination is the underlying reason for stomach infections, skin rashes, or frequent health issues among family members. Water tanks that have not been cleaned properly are one of the reasons where bacteria like E. coli and Legionella are commonly found.
8. Presence of Insects or Foreign Objects
The presence of insects, rodents, or foreign objects in the tank implies inadequate sealing and poor hygiene. The infiltration of contaminants compromising water safety is through holes or damaged lids. Contaminating even a small bug can be sufficient for large amounts of stored water.
A professional will conduct a thorough inspection and cleansing that will fix the problem, and then confirm proper sealing of the tank.
