Water is most important for our health, but only clear looking water is not safe to drink. Many types of minerals and dissolved things are found in water, which are called TDS i.e. Total Dissolved Solids. TDS means minerals, salts and metals dissolved in water. The correct TDS level of drinking water is very important for your health. In this blog we will understand the Normal TDS Level in Drinking Water and all the important things.
What is TDS?
TDS i.e. Total Dissolved Solids means the total amount of all solid things dissolved in water. These minerals can be calcium, magnesium, sodium, potassium, chloride, sulfate and other salts. TDS is usually measured in ppm (parts per million).
The right amount of TDS provides essential minerals to our body. But if TDS is too high or too low, then the taste, health and purity of water can be affected.

What should be the normal TDS level in drinking water?
Normal TDS for drinking water means the ideal TDS level of drinking water should be between 50 ppm to 250 ppm. According to the Bureau of Indian Standards (BIS), the TDS limit for drinking water can be up to 500 ppm.
- 0 – 50 ppm: Very less minerals, taste bland
- 50 – 150 ppm: Good and ideal (Ideal TDS for Drinking Water)
- 150 – 250 ppm: Normal and safe for health
- 250 – 500 ppm: Drinkable, but taste a bit heavy
More than 500 ppm: Not drinkable, filter required
Minimum TDS for Drinking Water
Many people think that RO filtered water with very low TDS is the best, but it is not so. The minimum TDS for drinking water should be 50 ppm, because water with a TDS lower than this does not provide the body with the necessary minerals and can affect health in the long run.
RO Water TDS Range
Nowadays, most homes use RO (Reverse Osmosis) water purifiers. The TDS of RO water is usually very low. It is best to keep the RO Water TDS Range between 50–150 ppm. In this range, the taste of water remains good and the essential minerals are also retained.
Best TDS Level for Drinking Water in India
Water from different places in India has different TDS levels. Generally, the best TDS level for drinking water in India should be between 100 ppm to 250 ppm. This water is neither too hard nor too soft, and it is best for health.
Disadvantages of high TDS
If the TDS of water is very high, then it also contains more dissolved salts and metals. This can make the water taste salty or bitter and can be harmful to health. Water with high TDS can affect the kidneys and problems like blood pressure can increase if consumed for a long time.
Disadvantages of low TDS
Water with very low TDS is also not good for the body. Very pure (0–20 ppm) water has almost no minerals. Drinking such water for a long time can cause a deficiency of minerals in the body, which can affect the strength of bones and teeth.
Ways to maintain normal TDS
- Correct setting of RO purifier: Use the TDS controller in your RO purifier and set it to 80–150 ppm.
- Check TDS regularly: Measure the TDS of your water every month with a TDS meter.
- Install a mineral cartridge: If the TDS of RO water is very low, then use a mineral cartridge or re-mineralization filter.
- Take water from the right source: If possible, take water from a natural source like borewell or municipal corporation whose TDS is already balanced.
Why is the Normal TDS Level in Drinking Water important?
- Supplies minerals to the body.
- Improves the taste of water.
- Maintains the electrolyte balance of the body.
- Protects health in the long term.
Important Tips
- Keep the TDS of drinking water between 50–250 ppm.
- Do not drink water with TDS more than 500 ppm.
If your water tastes strange, get a TDS test done immediately.
Conclusion
The purity of water depends not only on its clear appearance, but also on its TDS level. Normal TDS Level in Drinking Water is considered best between 50–250 ppm. Drinking Water TDS Limit can be up to 500 ppm, but water with higher TDS should be avoided. While using RO purifier, it is important to keep the RO Water TDS Range between 50–150 ppm. Remember, water with very low or very high TDS can cause harm to health. So always check the TDS of your drinking water and give safe and healthy water to your family.
