Most of us do not take the trouble of getting our water tanks cleaned periodically but this casualness can prove fatal.  Even if we use filtered water for drinking or cooking purpose, there are many places where we use unfiltered water such as bathing, washing dishes and clothes, brushing our teeth, washing fruits and vegetables etc. and hence we do consume it in some form or the other.

These days, water is stored in underground and overhead water tanks. Although these areas remain covered, foreign objects, pests, and other organisms such as algae and bacteria can still find their way into these tanks if not maintained properly. It may result in the formation of typhoid, typhus, dysentery, cholera and diseases such as hepatitis in our body. Additionally, the sand and rust particles in water tanks damage our purifier, laundry and dishwashing machines. In the water tanks that are not periodically cleaned, rodents, dead pests, worms, maggots, and plates of mud, rust and fungi form. The only way to avoid this is to disinfestation and cleaning of the water tanks with special chemicals and high pressure machines produced for tanks periodically at least once a year by the trained professionals.

Know the symptoms of unclean water in your water tanks

Foul smell

Water stored for long periods can give off a repugnant smell – indicative of formation of bacterial colonies on top of your stored water and sediments and minerals reacting to water and hydrogen. The most common culprit of the foul odour is hydrogen sulphide – a gas released by bacterial colonies due to change in temperature of the water.

Although the foul odour doesn’t necessarily mean the water is harmful to your health, the smell might keep you from drinking the water.

Bad taste

Iron gives water a metallic taste and is one of the most important and dominant minerals found in water. This metallic taste can change over time, indicating the mixture of alien minerals into your water due to improper cleaning of your water tank. 

While most of these extra minerals are harmless and exit naturally from the body, sometimes heavy metals such as lead, arsenic, cobalt, etc., can also mix in water and can lead to heavy metal poisoning. If you notice bad taste in your water, you should immediately clean your water tank.

Different colour:

Water is supposed to be clear and once you set it stationary in a glass, you should be able to see sediments settle down at the bottom. If, however, you find that your water is slightly rusty or any other colour and is leaving stains on your glass, it might mean excess iron in your water.

Colours other than rusty might mean there is some other impurity in your water. Green, for example means formation of algae in your water tank. You should immediately get your water tested.


Causes of Water Tank to Get Dirty

There are numerous reasons why a water tank can get dirty, including poor plumbing, cracks in the tank, or even some sort of opening allowing dust into the tank.


Algae can form in water tanks if water is left undisturbed for too long or if there is little to no sunlight in the tank. 


If left uncleaned for long, water tanks can accumulate sediments which dissolve into water each time you refill it. Although the amount is minute at the start, it can add up to finally be extremely hazardous to the human health.

Insects, Droppings, & Larvae

Insects can find their way into your water tank regardless of how many preventive measures you take. These can be ants, mosquitoes, spiders, or other insects. Once settled, they are bound to lay droppings and eggs in the water which can increase so much in number over the long run that they will start flowing through your taps.

Dead Animals

If your water tank isn’t completely sealed, it is bound to draw animals. Crows, pigeons, cats, and other animals can come to drink from your water tank and fall into the water, ultimately getting trapped inside. If they die inside the tank, their body starts disintegrating in the tank and can lead to chemical reactions that can render the whole water supply toxic.
