WHO Guidelines for TDS in Drinking Water: Health Standards Explained
Published by RO Care India - Your trusted water purification experts
Clean drinking water is not just about taste – it's about your family's health. When we talk about water quality, TDS (Total Dissolved Solids) becomes a crucial factor that directly impacts what flows from your tap to your glass. But what exactly does the World Health Organization say about safe TDS levels? Let's dive deep into understanding these vital health standards.
What is TDS and Why Does WHO Care About It?
Imagine your drinking water as a clear soup. While it looks transparent, it contains invisible minerals, salts, and other dissolved substances. TDS for drinking water as per WHO measures these dissolved particles in parts per million (ppm). Think of it like this – if you dissolved a teaspoon of salt in a large pot of water, that salt becomes part of the TDS count.
The WHO TDS level guidelines exist because these dissolved substances can significantly affect your health. Too little, and your body misses essential minerals. Too much, and you might face various health complications.
WHO Recommended TDS for Drinking Water: The Complete Breakdown
The WHO recommended TDS for drinking water sets clear boundaries for safe consumption:
Primary WHO Standards:
- Acceptable Range: 300-600 ppm
- Maximum Permissible Limit: 1000 ppm
- Optimal Health Range: 150-300 ppm
But here's where it gets interesting – these numbers tell a story about your water's journey and quality.
Understanding the TDS Categories:
Low TDS Water (0-150 ppm):
- Often from RO purification systems
- May lack essential minerals
- Can taste flat or bland
Ideal TDS Water (150-300 ppm):
- Perfect balance of minerals and purity
- Healthy TDS for drinking water range
- Tastes fresh and clean
Acceptable TDS Water (300-600 ppm):
- Still safe for daily consumption
- May have slightly mineral taste
- Generally well-tolerated
High TDS Water (600-1000 ppm):
- Approaching upper WHO limits
- May taste salty or bitter
- Requires attention
Dangerous TDS Water (Above 1000 ppm):
- Exceeds WHO safety standards
- Not recommended for regular consumption
- May cause health issues
The Science Behind Healthy Water TDS
Dr. Priya Sharma, a leading water quality researcher, explains: "The TDS of drinking water as per WHO isn't just a random number. It's based on decades of health studies across different populations worldwide."
Why These Numbers Matter:
For Your Kidneys: High TDS forces your kidneys to work overtime filtering excess minerals and salts. Over time, this can lead to kidney stones and other complications.
For Your Heart: Excessive dissolved salts can contribute to high blood pressure, especially in sensitive individuals.
For Your Digestive System: Very high TDS water can cause stomach upset, while very low TDS might not provide necessary electrolytes.
For Growing Children: Kids need the right mineral balance for proper bone and teeth development.
Real-Life Impact: A Mumbai Family's Story
The Patels from Mumbai discovered their bore well water had TDS levels of 1200 ppm – well above the drinking water TDS as per WHO standards. Mrs. Patel noticed her family frequently complained of stomach issues and metallic taste in their morning tea.
After installing a quality water purification system from RO Care India, their water TDS dropped to 250 ppm – right in the healthy TDS of water range. Within weeks, the family reported better taste, improved digestion, and peace of mind about their water quality.

RO Care India's Approach to Optimal TDS
At RO Care India, we understand that healthy water TDS isn't one-size-fits-all. Our water experts analyze your specific water source and recommend solutions that maintain WHO-compliant TDS levels while preserving essential minerals.
Our advanced purification systems ensure your family gets water that meets WHO TDS level guidelines without compromising on taste or health benefits.
Regional Considerations for Indian Households
India's diverse geography means water TDS varies dramatically:
Northern Plains: Often high TDS due to groundwater mineral content Coastal Areas: May have salt water intrusion affecting TDS Urban Areas: Municipal treatment but may need additional purification Rural Areas: Groundwater with varying TDS levels
Understanding your region's typical TDS helps in choosing the right purification approach.
Making the Right Choice for Your Family
Remember, the WHO recommended TDS for drinking water is a guideline, not a rigid rule. Factors like your family's health conditions, local water quality, and personal preferences all play a role.
The key is finding that sweet spot where your water is pure enough to be safe but mineral-rich enough to be healthy.

Frequently Asked Questions (FAQ)
Q1: What is the WHO recommended TDS level for drinking water? A: The WHO recommends TDS levels between 300-600 ppm as acceptable, with a maximum limit of 1000 ppm. The optimal healthy range is considered to be 150-300 ppm.
Q2: Is TDS below 50 ppm safe for drinking? A: While not immediately harmful, very low TDS water (below 50 ppm) may lack essential minerals. WHO suggests that extremely low TDS water should be remineralized for optimal health benefits.
Q3: Can high TDS water cause health problems? A: Yes, consistently drinking water with TDS above 1000 ppm can lead to kidney stones, digestive issues, and may contribute to high blood pressure over time.
Q4: How often should I check my water's TDS level? A: For households with water purification systems, monthly testing is recommended. If you rely on municipal or bore well water directly, weekly testing helps ensure safety.
Q5: Does boiling water reduce TDS levels? A: No, boiling water does not reduce TDS levels. It only kills bacteria and viruses. To reduce TDS, you need filtration systems like RO purifiers.
Q6: What's the difference between WHO and Indian standards for TDS? A: Indian standards (BIS) allow up to 2000 ppm in the absence of alternate sources, while WHO maintains 1000 ppm as the maximum. WHO standards are generally more stringent.
Q7: Can I drink RO water with very low TDS daily? A: While safe short-term, long-term consumption of very low TDS water may require mineral supplementation. It's best to maintain TDS in the 150-300 ppm range.
Q8: How does TDS affect the taste of water? A: Low TDS water tastes flat, while high TDS water may taste salty, bitter, or metallic. The ideal TDS range provides a fresh, clean taste.
