Understanding the water quality in Patna is critical for every household. If you live in Patna, you might have noticed a reddish tint in your bucket, a white layer on your taps, or a slightly metallic taste in your glass. You aren't imagining it.

While the municipal supply (Nal Jal Yojana) has improved access, the groundwater in many localities—especially Kankarbagh, Danapur, and Boring Road—is facing serious contamination issues.

Is it safe to drink directly from the tap? Do you really need an RO? Let’s look at the data.

3 Hidden Dangers Affecting Water Quality in Patna

According to recent reports from the Bureau of Indian Standards (BIS) and local testing, Patna's groundwater suffers from three main enemies:

1. High TDS (Total Dissolved Solids)

In areas like Kankarbagh and Hanuman Nagar, TDS levels often spike above 800-1200 ppm. Safe drinking water should be below 500 ppm. High TDS affects the water quality in Patna significantly, making it taste salty and potentially leading to kidney stones over long-term consumption.

2. Iron Contamination (The "Red Water" Problem)

Residents in Danapur and Patliputra frequently report yellowish or reddish water. This is due to excess Iron. While iron is a nutrient, in high doses, it damages your hair, skin, and digestive system—not to mention it ruins your RO membrane quickly.

Locality Check: What’s in Your Water?

Based on our service visits across the city, here is what we typically find regarding the water quality in Patna neighborhoods:

• Boring Road / SK Puri: Moderate TDS (500-700 ppm), but high hardness (scaling). Requires RO + Antiscalant.
• Kankarbagh / Rajendra Nagar: Very High TDS (1000+ ppm). Requires a heavy-duty RO membrane.
• Danapur / Khagaul: High Iron content. Requires an extra Iron Remover pre-filter.
• Patna City / Didarganj: Risk of bacterial contamination due to old pipelines. UV protection is mandatory here.

The Solution: Which RO is Best for Patna?

Given the high TDS and Iron content, a simple UV or Gravity filter is not enough for Patna. You need a machine that offers:

1. RO Technology: To remove Dissolved Solids and Arsenic.
2. UV / UF: To kill bacteria and cysts.
3. TDS Controller: To ensure the water doesn't become too acidic (a common issue with cheap ROs).

Our top recommendation for Patna homes is the Kent Supreme Plus. It handles high TDS exceptionally well and its "Zero Water Wastage" tech is crucial for Bihar.

How to Test Water Quality in Patna at Home?

You don't need a lab to know if your water is safe. Here are two simple ways to check the water quality in Patna right now:

• The TDS Meter Test: You can buy a digital TDS meter online for under ₹300. Dip it in your tap water. If the reading is above 500, you need an RO. If it's above 1000, the water is "Hard."
• The "Soap Test": Try to lather soap in a bucket of water. If it doesn't foam easily and leaves a sticky scum, you have "Hard Water" (High Calcium/Magnesium), which ruins appliances and hair.

Don't Ignore Your RO Service

In Patna, because the water has high sediment and iron, your RO filters choke faster than in other cities. If you don't change your Sediment Filter every 3-4 months, the iron will destroy your expensive RO Membrane.
