What is the Best TDS Value For Drinking Water? [2022]

The Best TDS Value for Drinking Water can offer you a new insight into healthy drinking water. TDS, or the ‘total Dissolved Solids’, is an analysis of all the inorganic elements like Potassium, Sodium, Chloride, Sulfate, bicarbonates, and Magnesium. The value of the TDS gives the idea of how safe a certain portion of drinking water is. Interestingly, the TDS of a water body changes constantly according to the geographical area it travels through. Usually, the origins of drinking water are steam, a river, or even sewage and wastewater. Hence, it is all the more important to ensure you have the right kind of TDS value of the water when you are consuming it for your daily purposes.


There are times when we experience a bad taste or odour from our drinking water. Did you know that this is due to the presence of inorganic salts in it? The ‘safe levels’ of the TDS, according to the Indian Authorities, are recommended to be around 500 mg/l. Hence, if you need to check the TDS levels for water you have been obtaining from nearby natural sources, be sure that the TDS levels are well within the recommended levels.

The BIS: Bureau of Indian Standards has also warned that if the TDS values cross the recommended levels, one can expect the taste to be ‘funny’ and lead to gastrointestinal irritations. However, if there are no other alternatives nearby, one can settle for a relaxed TDS value of 2000 mg/l.

The Water TDS Value for Drinking

Let’s take a look at the acceptable TDS values of the water:

TDS Level (mg/litre)


Less than 300





Not exactly fit for drinking

900 – 1200

Not fit for drinking

Beyond 1200


The Normal TDS Value For Drinking: How To Understand The Table

Let us have a better understanding of the various TDS levels and what makes a certain water body safe or unfit for consumption:

TDS Level (mg/litre)


Less than 50 mg/l

The water with much less TDS is not considered fit for drinking as it does not include essential minerals.

50-150 mg/l

Can be consumed. However, ensure that if you are utilizing an RO it should have a TDS value maintained below 80 mg/l

150-250 mg/l

This is considered to be perfect for people suffering from certain cardiovascular issues.

250-350 mg/l

This is the acceptable TDS value for most urban Indian homes.

350-500 mg/l

According to the BIS, the TDS values below 500 mg/l are perfect for consumption.

500-900 mg/l

This is not recommended, and it is advised to use an RO with a Mineralizer or a TDS controller.

900-1200 mg/l

Not safe, use RO with TDS controller or Mineralizer.

1200-2000 mg/l

Not safe, use RO with TDS controller or Mineralizer.

More than 2000 mg/l

Dangerous for consumption. Avoid at all costs.

The Accepted TDS Level For Drinking Water: How To Maintain It

While the TDS might be an issue in nature, nevertheless, you need not have to suffer from the horrific health hazards due to the same. Here are some tips and tricks on how to maintain the right level of TDS in the water you consume:

  1. One of the best ways to maintain the right levels of TDS is to install a nice RO system in your home and residence. These comprise in-built features that function to maintain the TDS of the water you are consuming. The RO comprises a semipermeable membrane with pores of 0.0001 microns. This ensures that the water seeps across the membrane, and the harmful particles and microbes remain behind on the membrane. Certain models of the RO comprise an additional filter membrane as well, which is used to eliminate the larger particles from the water, making it all the fitter for consumption.
  2. Using the TDS meter is yet another great method to check the TDS of the water you plan to consume. To use it, you need to:
    – Take off the protective cap from the TDS meter.
    – Locate the ON/OFF switch and switch it ON.
    – Now, immerse the TDS meter into the water up to the immersion level prescribed.
    – Allow the reading to stabilize; this can take about 10 seconds to do so.
    – Now, press the HOLD button located on the surface of the device to view the reading.
    – There are times when the reading will display the ‘X10’ symbol; this essentially implies the fact that you will have to multiply the reading with 10 to get the accurate one.
    – Once you have got the reading, shake off the excess water from the device, wipe dry and store it back for future use.

How Does The TDS Effects Our Overall Health?

Now that you know the ideal TDS value for drinking water, let us see how it affects our everyday health:

The Taste: You can know that the water you are consuming comprises a ‘questionable TDS’ simply by the taste of it. This water usually has a salty taste and can alter the taste of the food used in cooking.

The Health: Unless above 1000 ppm, the TDS levels are considered safe for consumption. Nevertheless, the presence of certain microorganisms, Copper, and lead can be a major health concern.

The Scaling: There are chances that the high TDS water might cause scaling of the utensils it is used for storage and other utility purposes. There are also chances that the high TDS water can ruin your geysers, dishwashers, washing machines, and more. This will lead to the long-term damages and replacement issued of the appliances.

Best Tds Value For Drinking Water?: The Conclusion

So, there you have it, people; these are a few aspects, facts, and features about the TDS of the water you consume. Water is life, and you must take care of the quality of the water you are consuming. The TDS value offers a direct idea about how safe your water is for you to be able to consume safely.
