Dadra & Nagar Haveli and Daman & Diu

Dadra & Nagar Haveli and Daman & Diu averages about 298 ppm across 11 covered cities and towns, which puts much of the state in a moderate hard-water range for household appliances. That is enough to create visible scale, slower heating, and higher maintenance needs even when the water looks normal.

In this dataset, Diu is currently the highest covered city in Dadra & Nagar Haveli and Daman & Diu at about 320 ppm. That level is strong enough to justify more aggressive descaling for geysers, kettles, and washing machines.

In lower-TDS parts of Dadra & Nagar Haveli and Daman & Diu, appliances usually need periodic rather than constant descaling, but regular maintenance still matters because repeated heating leaves deposits behind over time.

Yes. Dadra & Nagar Haveli and Daman & Diu is not one uniform water market. In this dataset the range runs from about 278 ppm in Naroli up to about 320 ppm in Diu, which is why city-level pages matter more than broad statewide assumptions.
