About STM Mineral Water
Purity You Can Trust
A Local Name You Can Trust
STM Mineral Water started with a simple promise: every household and office in our service area deserves clean, safe drinking water at a fair price, delivered on time, every time.
What began as a single delivery van serving a handful of neighbourhoods in Kolkata has grown into a full-fledged distribution network covering 40+ areas across the city and its suburbs. We manufacture and pack our own 20 litre jars and bottled water at our RO-purification facility, so every step — from purification to your doorstep — stays under our control and our quality standards.
Today we serve homes, offices, schools, hospitals and event caterers with daily, alternate-day and weekly subscription plans, backed by a team of trained delivery staff and a support desk that actually picks up the phone.
Our Mission
To make safe, purified drinking water accessible and affordable for every home and business in our service area, through reliable delivery and honest pricing — no hidden charges, no compromises on quality.
Our Vision
To become West Bengal's most trusted water delivery brand by combining modern purification technology with the personal touch of a neighbourhood service you can call by name.
Our Quality & Purification Process
1. Sediment Filtration
Raw water passes through multi-layer sediment filters to remove suspended particles, sand and rust.
2. Reverse Osmosis (RO)
A high-pressure RO membrane removes dissolved salts, heavy metals and impurities, correcting TDS to the safe range.
3. UV Sterilisation
UV chambers neutralise bacteria and viruses without adding any chemicals, preserving natural taste and minerals.
4. Ozonation & Testing
Ozone treatment before filling keeps jars contamination-free; every batch is lab-tested before dispatch.
