Uniwater in Kolkata.
Our home city. Treated municipal in central Kolkata; borewell augmentation common across the EM Bypass suburbs.

The water
What Kolkata water actually looks like.
Salt Lake, Rajarhat, and New Town run on a mix of municipal and borewell. Arsenic risk in some suburban borewells — testing matters. Central Kolkata is largely treated supply; hardness moderate, iron usually low.

Systems we install here
What goes into a Kolkata home, typically.
The right answer comes from the survey, not the catalogue. These are the four systems most commonly specified in Kolkata, in order of how often they appear on installation invoices.
Whole-house filtration
One softened, filtered supply for the whole house. Every shower, every sink, every appliance.
Bathroom water filters
A bathroom filter has to do three things at once: treat the water, fit the space, not announce itself.
Drinking water systems
The kitchen is the one tap where chemistry matters more than feel. The shower can forgive imperfect water. The kitchen cannot.
Iron filter
Borewell-fed homes have it. Old galvanised mains have it. Orange grout. Faint stains under the WC rim.
Charnock Hospital
Drinking-water RO at point of use, building inlet WTP, monthly AMC.
Service is the system
Most water companies show up when something breaks. We show up every month.
Automated.
Backwash, regeneration, flush — the system handles routine cycles on a schedule. No valves to turn.
Verified by an engineer.
Monthly site visit. Pressure check, media inspection, hardness/iron spot test, written report.
Owned by us.
If something needs replacement or recalibration, we do it. No customer chasing parts.
The discipline that decides year four.
