Hard Water in
Sikkim

Sikkim averages about 197 ppm across 19 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, Singtam is currently the highest covered city in Sikkim at about 212 ppm. That level is strong enough to justify more aggressive descaling for geysers, kettles, and washing machines.

In lower-TDS parts of Sikkim, appliances usually need periodic rather than constant descaling, but regular maintenance still matters because repeated heating leaves deposits behind over time.

Yes. Sikkim is not one uniform water market. In this dataset the range runs from about 170 ppm in Lachen up to about 212 ppm in Singtam, which is why city-level pages matter more than broad statewide assumptions.
