Why Uniwater
The water company that stays.
Kent and Aquaguard sell a purifier for the kitchen tap. Industrial firms build plants for factories. We do the part in between: the whole house, every tap, tested and serviced by the same team.
The category
Between the purifier brands and the industrial firms.
India has two visible water-treatment categories: kitchen-purifier brands (Aquaguard, Kent, Zero B, Eureka Forbes) and industrial EPC firms. One sells a single-tap unit through dealers. The other runs projects with install teams you never meet.
Neither looks after the homeowner who wants every tap, every appliance and the next ten years of upkeep handled by one team. That’s the gap we work in.
We survey, we install, and we keep coming back for the life of the contract.
How we work
What we do differently.
01
We size it to your water.
Every system starts with a survey of your water, pressure, usage and space. Catalogue sizes are where we start, not what we sell you.
02
We hide it in the house.
False ceiling, plumbing shaft, behind a cabinet, under the counter or outside a window. We pick the spot at survey so nobody sees the system and our engineer can still reach it.
03
We come back every month.
An engineer visits every month for the life of the contract. The system runs its own backwash and regeneration; our engineer does the inspection, the calibration and anything unexpected.
System selector
Which Uniwater system does your water need?
Three branches, one for each kind of need. Every product at the end of a branch is a real Uniwater product. Under each branch we also name the cheaper option that may suit you better, because sometimes we aren’t the right answer.
Drinking water only
The kitchen tap only: the water you drink, not the water you bathe in.
One family, one kitchen
Test the TDS first.
Centralised drinking for an office, school, hotel, hospital
Daily volume decides the system.
For example, tap-mount and shower-head filters on Amazon (₹1K–4K). They don’t reduce TDS or hardness; they sequester it. You fit them yourself and change the cartridge every six months. Fine for what they are.
Whole bathroom, whole house
Soft water wherever it’s used: showers, basins, the geyser, the washing machine.
One bathroom, with high demand or a visible install
Sized to the bathroom’s load.
Whole house: villa, several bathrooms, borewell or variable supply
Sediment → iron → carbon → softener. Sized to the home.
For example, dealer-sold ion-exchange softeners from large home-appliance brands (₹15K–60K). Real softening. Service depends on the dealer. Often not tuned for borewell-fed homes or multi-stage treatment.
A building, a hotel, a hospital, a complex
Treated once at the inlet, so every flat and every floor gets the same water.
Sized for the load
Specified after site survey and water analysis.
Works if your in-house plant team will own service, resin, salt, and consumables for fifteen years. Stops working when the team turns over.
Why we’re different
How most water companies work, and how we do it.
Most companies sell you a box and leave. A system needs four things over its life: a proper survey, the right design, an install that fits the house and regular service from people who know it. We do all four.
Topic
What most sellers do
What Uniwater does
How they price
What most sellers do
They quote first and fit a catalogue SKU to the buyer. The water gets tested after the sale, if at all.
What Uniwater does
We survey first: test the water, map the plumbing, size for the household. The quote is for your water, not a generic SKU.
Who installs
What most sellers do
Local plumbers on commission, a different one each visit. The salesperson never sees the install.
What Uniwater does
A Uniwater engineer designs the system and the same team installs it. The person who quoted is on site at handover.
After handover
What most sellers do
A flat-rate AMC and a visit when something breaks, from an engineer who has never seen your system.
What Uniwater does
An engineer visits every month for the life of the contract. The same team looks after the system throughout.
When water chemistry changes
What most sellers do
Resin clogs in year two and output drops. You assume the unit failed and buy a new one.
What Uniwater does
The monthly report shows the drift. We swap media, adjust settings and check the sequence, all under the contract and not billed as extras.
How we compare
Which brand is right for which problem?
Uniwater isn’t the right answer for every household. Here’s who we’d send you to instead.
Single tap, drinking water only, municipal supply
For a single tap on a stable municipal supply, mass-market kitchen RO does the job. Don’t overspend.
Hair / skin / fittings problems, no kitchen drinking-water issue
Kitchen-purifier brands don’t treat bathroom water. Whole-house and bathroom treatment is what we do.
Borewell water with iron, hardness, and orange staining
Borewell chemistry needs sequence: iron first, then softening, then carbon. Kent / Aquaguard don’t sell this.
You want monthly service with documented reports
Eureka Forbes offers AMC tiers but doesn’t include monthly visits. Zero B services on demand. Monthly service is where we’re different.
Building / hotel / hospital / factory water requirement
We engineer up to 50,000 LPH RO, 10,000 LPH DM, 100 KLD WTP. For petrochemical-scale or municipal, the right answer is a tier-one EPC firm.
Lowest price, online order, no install or service expected
We don’t sell off-the-shelf. Every system is surveyed and sized first. That takes more of your time, and if you don’t want that, we’re the wrong company.
What we don’t claim
Things you won’t hear from us.
You’ll hear these from other water companies. Not from us.
- The cheapest.
We aren’t. A system sized for your water costs what it costs.
- The biggest range.
We have 100+ engineered configurations, but you only need the one your survey points to.
- Patented technology.
We use resin, media and membranes from named manufacturers, and we tell you which ones. No made-up acronyms.
- Number one in India.
We’re a Kolkata company working in nine cities. We don’t need the title.
Components from
The names on the parts.
We don’t make pumps, resin or membranes. We buy them from the manufacturers below and name them on every quote.
Pumps, resin, media, membranes and controls are specified for each system at survey. We don’t swap them after the quote.
