Water TDS Level: What It Is and Why It Matters for Safe Drinking Water

Published on June 23, 2024

Do you ever wonder what makes your drinking water safe? One of the most crucial factors is the water TDS level. TDS, or Total Dissolved Solids, indicates the concentration of dissolved substances like minerals, salts, and heavy metals in water. Monitoring this level ensures you and your family consume clean and healthy water.

If you live in cities like Mumbai or areas with hard water, high TDS levels can lead to health issues and appliance damage. This guide will help you understand TDS in water, how it affects your health, and how to manage it effectively.

What Is TDS in Water?

TDS stands for Total Dissolved Solids, representing both organic and inorganic substances dissolved in water. These include:

Heavy metals like lead and arsenic
Minerals such as calcium and magnesium
Salts, chlorides, and sulfates
Industrial and agricultural contaminants

Water naturally absorbs these elements from the environment, pipelines, and treatment processes. While some minerals are beneficial, excessive amounts can compromise water quality.

Ideal Water TDS Levels for Drinking

TDS is measured in PPM (Parts Per Million). Here’s a quick reference chart:

TDS Level (PPM)	Water Quality
50-150	Excellent (Ideal for drinking)
150-250	Good
250-300	Fair
300-500	Poor (Needs purification)
Above 500	Unsafe (Not recommended)

According to the Bureau of Indian Standards (BIS), the acceptable TDS limit is 500 PPM, while the World Health Organization (WHO) recommends less than 300 PPM for optimal taste and safety.

Why Is High TDS in Water a Concern?

Consuming water with a high TDS level can lead to:
✅ Health Risks: Exposure to harmful elements like fluoride, arsenic, and lead can cause long-term health issues.
✅ Unpleasant Taste and Odor: High TDS makes water taste salty or bitter.
✅ Appliance Damage: It causes scaling in kettles, pipes, and washing machines, reducing their efficiency.
✅ Stains on Utensils and Tiles: Mineral buildup leaves white spots and residue.

How to Reduce High TDS Levels in Water

The most effective solution to reduce TDS is installing an RO (Reverse Osmosis) water purifier. Here’s why:
🔹 RO Technology: Filters water through a semi-permeable membrane, removing up to 99% of dissolved solids.
🔹 Improves Taste and Odor: Removes contaminants that cause unpleasant flavors.
🔹 Suitable for High TDS Levels: Ideal for areas where TDS exceeds 500 PPM.

For example, borewell water often has TDS levels between 500-2000 PPM, making RO filtration essential.

Best TDS Level for RO Water

After RO filtration, the optimal TDS level for drinking water should be between 50-150 PPM. This range maintains essential minerals while removing harmful substances, providing you with water that’s both safe and pleasant to drink.

Why Choose an RO Water Purifier?

✅ Removes Harmful Contaminants: Eliminates arsenic, lead, nitrates, and other toxins.
✅ Improves Appliance Lifespan: Reduces scaling, protecting your kitchen appliances.
✅ Enhances Water Taste: Makes water more refreshing and enjoyable.
✅ Safe for Long-Term Consumption: Provides clean water without compromising essential minerals.

Frequently Asked Questions (FAQs)

🔎 What is the recommended TDS level for drinking water?
👉 The BIS recommends below 500 PPM, while WHO suggests less than 300 PPM for the best taste and safety.

🔎 Can low TDS levels be harmful?
👉 Extremely low TDS (below 50 PPM) can result in flat-tasting water but isn’t typically harmful.

🔎 Is RO purification necessary for municipal water?
👉 If municipal water has a TDS level above 250 PPM, using an RO purifier can improve taste and safety.

🔎 How often should I check the TDS of my water?
👉 It’s advisable to check the TDS every 3-6 months or whenever there’s a noticeable change in taste or clarity.

Final Thoughts

Your water TDS level directly impacts your health and the longevity of household appliances. Regularly testing and maintaining an ideal TDS range ensures safe, clean, and better-tasting water. Invest in a reliable RO purifier to keep contaminants at bay and enjoy peace of mind with every sip.
