Drinking water systems
The kitchen is the one tap where chemistry matters more than feel. The shower can forgive imperfect water. The kitchen cannot.
From ₹15,000. Final price after free survey. EMI from ₹1,250/month via Bajaj Finserv / Snapmint.
The problem this solves
What changes when the water is right.
Bottled water bills run ₹12,000–18,000 a year. A kitchen system pays for itself in eighteen months.
RO when TDS runs high. UF with UV when it runs low. Same kitchen, different chemistry, different answer.
Wall-mounted, under-sink, or centralised. The plumbing decides where it goes.
Re-mineralisation matters. RO water that strips magnesium and calcium tastes flat and isn’t healthier.
How we solve it
Sized to the water, the house, and the people in it.
Every Uniwater drinking water systems starts with a free water test and a site survey. The chemistry decides the media. The household decides the capacity. The architecture decides where it goes.
Catalogue sizes are starting points, not the sale. Our 17-rule auto-suggest engine generates a bill of materials specific to your water analysis, pressure, and draw — not a generic SKU pulled off a shelf.
Engineered, not bought off a shelf.
TDS decides
Test the TDS first.
What’s included
Everything to put it in. Everything to keep it running.
Engineered vessel + media
FRP or SS316 vessel, sized to your draw and chemistry. Media chosen for the specific problem.
Controls & valves
Manual or automatic regeneration. Pressure gauges and flow meters where they matter.
Installation
Plumbing, electrical, mounting, and commissioning. Documented before handover.
Water analysis
Pre-install and post-install parameter readings. Filed with your quote.
One-year warranty
All system components covered. Replacement, not repair-by-letter.
One-year AMC included
Monthly preventive service on Comprehensive / Premium tiers. Standard tier gets quarterly.
Where it goes
The kitchen is the one tap.
Drinking water gets its own treatment, sized to your TDS. Wall-mounted, under-sink, or centralised — the plumbing decides where it goes.
below 200 ppm → UF + UV
Ultrafiltration with UV. Natural minerals stay. Pathogens go.
200–500 ppm → Test & consult
Borderline range. Hardness, iron, and use case decide RO vs UF.
above 500 ppm → RO
Reverse osmosis with post-RO mineral correction. Re-mineralised. Doesn’t taste flat.
Architectural patterns
How the system fits, on paper.
Section drawings of the install patterns we use most often for this system. Pre-tile, mid-construction, or as a retrofit — the right pattern is decided at survey, against the house.
05 · Under-basin
Point-of-use install under the kitchen vanity. Service via cabinet door, no impact on finishes.
Configurations
Three or four sizes. Decided by load, not by SKU.
We don’t expose part numbers. The configuration is decided at survey based on bathroom count, household draw, and water chemistry.
Kitchen RO
Wall-mounted or under-sink
For TDS above 200 ppm. With post-RO mineral correction.
Kitchen Non-RO (UF + UV)
Wall-mounted
For TDS below 200 ppm. Natural minerals stay; pathogens go.
Centralised 25–50–100 LPH
Plant room
For villas, offices, schools, clinics. Drinking-quality at scale.

The thinking behind this system.
Pieces from the Journal that cover the chemistry, the decision, and the practice this solution rests on.
TDS isn't a quality metric. Here's what is.
Low TDS is not purer. High TDS is not dirtier. What total dissolved solids actually measures, and the parameter that matters more.
Re-mineralisation after RO: why it matters
RO strips everything. Re-mineralisation adds back what the body and the taste need. The post-RO stage that turns flat water into real water.
How to read a water test report
TDS, hardness, iron, pH, FRC — five numbers that decide what your water needs. What each one measures, what the thresholds mean, and what to ask the tester.
