Water is crucial for our survival, but not all water is safe for drinking. One of the most important parameters of water quality is TDS, or Total Dissolved Solids. In regions like Morbi and Rajkot, where groundwater is heavily loaded with natural minerals and industrial by-products, understanding TDS is vital for protecting your family's health.

What is TDS and Why Does it Matter?

TDS refers to the concentration of dissolved inorganic salts and organic matter in water. Common constituents include calcium, magnesium, sodium, potassium, carbonates, bicarbonates, chlorides, and sulphates. A moderate amount of these minerals is necessary for human health and gives water its natural taste. However, very high TDS levels can make water hard, salty, and potentially hazardous over time.

Recommended TDS Level Guidelines

According to the Bureau of Indian Standards (BIS) and the World Health Organization (WHO), here is how water TDS is classified (measured in mg/L or ppm):

  • Below 50 ppm: Too low. Water of this level is highly acidic and lacks essential minerals like calcium and magnesium. It has a flat, bland taste and can strip minerals from your body.
  • 50 to 150 ppm: Ideal range. This is the sweet spot for drinking water. It is light, refreshing, safe, and retains a healthy mineral balance.
  • 150 to 300 ppm: Good. Safe for general consumption and has a standard taste.
  • 300 to 500 ppm: Acceptable. Safe to drink, but might feel heavy or slightly hard.
  • Above 500 ppm: Poor quality. Not recommended for drinking. Water feels hard, leaves white scales on utensils, and has a bitter/salty taste.
  • Above 1000 ppm: Unfit for consumption. Drinking this water long-term places heavy stress on the kidneys and can lead to kidney stones and digestive issues.

The Situation in Morbi & Rajkot

In Morbi (Ravapar, Vavdi, Lakhdhirpur) and parts of Rajkot, the raw groundwater TDS ranges between 800 ppm to over 2500 ppm. This makes domestic RO (Reverse Osmosis) purifiers a absolute necessity rather than a luxury. An RO membrane filters out up to 90-95% of these dissolved salts.

How to Maintain the Ideal TDS?

Modern RO systems from Shivam Water Solution are equipped with a TDS Controller (or Modulator). This valve allows service technicians to blend a tiny, safe amount of filtered water back into the RO water, calibrating the final output to the ideal 80-120 ppm range. This maintains both health benefits and the taste of your water.

Conclusion

Make sure to get your RO water tested regularly. If the water tastes different or feels heavy, your filters may be exhausted, causing the TDS to spike. At Shivam Water Solution, we provide free digital TDS testing for homes in Morbi.
