TDS of water in Bangalore by area — Rajajinagar, Whitefield, HSR & more (2026)

If you live in Bangalore, the quality of water reaching your tap depends almost entirely on your area. Cauvery water is relatively soft, but most apartments and independent houses also rely on borewell water — where TDS (Total Dissolved Solids) can swing dramatically. Here's a practical, area-wise guide based on what our service team sees every week across Bengaluru.

What is TDS and why does it matter?

TDS is the total amount of dissolved minerals, salts and metals in your water, measured in parts per million (ppm). BIS recommends drinking water under 500 ppm. Above 1,000 ppm you start tasting it; above 2,000 ppm it's hard on your kidneys and appliances.

Do you need an RO purifier?

• < 150 ppm — Excellent quality. An RO system is unnecessary; opt for a UV or UV+UF purifier.
• 150–300 ppm — Good quality. Still safe to consume without an RO.
• 300–500 ppm — Acceptable, but high in minerals. An RO+UV or RO+UF purifier is recommended to improve taste and reduce hardness.
• > 500 ppm — Poor quality. An RO system is essential.

Typical TDS by Bangalore area

These are ranges we measure during free demos — yours can differ borewell to borewell.

• Rajajinagar, Malleshwaram, Basavanagudi — 250–600 ppm (Cauvery dominant)
• Jayanagar, JP Nagar, BTM Layout — 300–700 ppm
• HSR Layout, Koramangala, Indiranagar — 400–900 ppm
• Whitefield, Marathahalli, Bellandur, Sarjapur — 800–1,800 ppm (heavy borewell)
• Electronic City, Bommanahalli — 700–1,500 ppm
• Yelahanka, Hennur, Thanisandra — 600–1,400 ppm
• Hebbal, RT Nagar, Banaswadi — 400–1,000 ppm

Which Aqua Kline model suits your TDS?

• Up to 500 ppm → M Series or L Series (RO + UV)
• 500–1,200 ppm → H+ Series (RO + UV + UF + Alkaline + Copper)
• 1,200+ ppm or commercial → S / S+ / S Pro Series
