Clean Water as a Service
Stop buying water plants. Buy water outcomes.
Uniwater designs, funds, owns, installs, operates and maintains the entire treatment system. You pay one predictable fee for water held to specification. Zero capital, zero downtime, zero operational burden.
Who CWaaS is for
Three audiences. Three contracts. One model.
Clean Water as a Service is sold to commercial buyers, industrial buyers, and residential society management committees. Not to individual homeowners — for that we install BathSoft, HomeSoft, or a kitchen drinking-water system instead.
Commercial
Offices, hospitality, healthcare, education.
Drinking water on every floor that meets IS 10500. Soft water for hotels and laundries. The plant is ours; the building is yours.

The model
Three things change when water is a service.
01
Zero capital outlay.
We design, fund, own and install the plant. Nothing lands on your capex sheet. You start paying when the water meets spec.
02
Guaranteed to spec.
An agreed water-quality standard, backed by an SLA. Iron, hardness, TDS, conductivity — held to the line that matters for your application.
03
Fully managed.
Monthly preventive engineer visits, consumables, media, membranes, repairs — all included. The system is ours to keep running.
The five lines
One contract. Five water lines, sized to what you need.
Drinking, iron-free, soft, RO process, and DM — each carries its own SLA, sized at survey to your demand and your supply chemistry.

How it works
Survey to running water, one decision at a time.
Free water survey.
We test source water and map real demand on site. No quote without it.
We design and install.
The right plant for your readings, funded and engineered by Uniwater.
Water to spec.
Metered, monitored, delivered to the agreed standard from day one.
We keep it running.
Monthly engineer visits; media, membranes, and repairs all covered.
Already running
10 live sites, 2 countries.
Every site below is a real deployment under contract. Soft, drinking and DM lines have running references; the iron-free and RO-process lines are signing their first deployments now and will appear here once commissioned — we don’t name reference sites that don’t exist yet.
Homes on managed soft water
Soft water delivered per day
Students on managed drinking water

What makes it a service
A named engineer visits every month.
The same person, on the same schedule, doing preventive work before anything fails. Backwash verification, parameter testing, salt and media top-up, membrane checks, a written report you keep. The plant stays in spec because someone whose job is to keep it in spec is on site every month.
Owning a plant is a project. Subscribing to water held to spec is a decision.
Your next step
Get a free water survey for your site.
One business day to an engineer assignment; five working days to a site survey and water analysis. The survey is free; you only pay if you decide to subscribe.
