Borewell water TDS in Indiranagar: is it safe to drink?
A plain-English read on Indiranagar's water — how hard it typically is, what that means for TDS and drinking safety, and how to check your own supply.
Indiranagar typically has moderately hard water
Homes around Indiranagar draw mostly treated Cauvery supply (medium-confidence area estimate). TDS is usually within — or close to — the BIS acceptable limit of 500 ppm.
This is a directional, area-level signal — not a measurement of your building's water. Boreholes vary street to street.
What TDS is safe to drink? (BIS limits)
| TDS (ppm) | What it means |
|---|---|
| Under 300 | Excellent — soft, good-tasting. |
| 300 – 500 | Good — within the BIS acceptable limit. |
| 500 – 2000 | Above the acceptable limit; BIS permits it only where no better source exists. Hard, often tastes off — filtering helps. |
| Over 2000 | Beyond the BIS permissible limit — not recommended for drinking without treatment. |

Indiranagar water — frequently asked
Is borewell water in Indiranagar safe to drink?
Homes around Indiranagar typically have moderately hard water from mostly treated Cauvery supply. TDS is usually within — or close to — the BIS acceptable limit of 500 ppm. Hardness and TDS are directional area signals, not a measurement — test your own supply before deciding, and treat or filter if it reads above the BIS acceptable limit.
What TDS level is safe for drinking water in India?
Under the BIS standard (IS 10500), a TDS of up to 500 ppm is acceptable for drinking water. Between 500 and 2000 ppm is permissible only where no better source exists; above 2000 ppm is not recommended for drinking. By palatability, under 300 ppm is excellent and 600–900 ppm is only fair.
Do I need an RO purifier in Indiranagar?
If your supply tests above ~500 ppm TDS or runs hard, an RO or a hardness-appropriate filter helps with taste, scaling, and appliance life. In moderately hard-water areas an RO is often worthwhile — but confirm your reading first; over-purifying already-soft water isn't necessary.
Why is Indiranagar water moderately hard?
It is mostly treated Cauvery supply. Bengaluru's Cauvery-supplied core runs softer, while borewell-dependent peripheral and IT-corridor zones draw hard groundwater with higher dissolved minerals.
