Water ATM Software

Run a Water ATM network like one connected business

Hydrotec built the software behind its own Arosia Water ATM product line — RFID, coin and digital-payment dispensing units deployed across India. The same platform manages machine health, sales, water quality and maintenance for any Water ATM fleet, from a single kiosk to a citywide network.

The problem

A fleet of kiosks is hard to run without software

A Water ATM is simple for the person filling a bottle. Running dozens or hundreds of them — profitably, safely and with consistent water quality — is an operations problem most hardware vendors don't solve.

  • No visibility into which machines are online, low on stock, or down for maintenance
  • Cash and digital payments reconciled manually across sites
  • Water quality checked in person instead of continuously
  • Maintenance requests that arrive by phone call, if at all

The Hydrotec approach

Fleet management built specifically for Water ATMs

Every Arosia Water ATM reports machine status, dispensing activity, revenue and (where sensors are fitted) water quality back to Hydrotec's platform. Operators get one console for the entire fleet — the same console model applies to third-party Water ATM hardware integrated over Hydrotec's Water ATM API.

From the field

An Arosia Water ATM in the field. Hydrotec's software runs the machines behind this hardware — dispensing, payments, quality readings and maintenance state all report back to the same platform documented on this page.

Features

What's included

Fleet status

Online/offline state, tank level and dispensing activity for every machine, updated in real time.

Payments & revenue

RFID card, coin and digital payment transactions reconciled automatically across machines.

Water quality

pH and TDS readings tied to each machine where quality sensors are installed.

Location & mapping

See every deployment on a map, grouped by city, region or operator territory.

Maintenance tracking

Faults and service requests logged against each machine with resolution history.

Alerts

Automatic alerts for offline machines, low tank levels or out-of-range quality readings.

Architecture

From the dispensing unit to your operations console

Each Water ATM connects to Hydrotec's cloud platform, which powers the operator dashboard, the customer and operator mobile apps, and any system you integrate through the Water ATM API.

Use cases

Where this fits

Municipal drinking water access

Public-facing kiosks in parks, transit hubs and civic spaces — see our NDMC, New Delhi deployment.

Solar & off-grid deployments

Machines running on solar with battery backup in areas with unreliable grid power, as deployed in Konark, Odisha.

Community & institutional access

Schools, bus depots and community centers where a fixed refill point serves daily demand.

Technical detail

How machines connect

Arosia units and integrated third-party hardware report over standard connectivity to Hydrotec's ingestion layer.

  • Dispensing events, tank levels and payment transactions synced from each machine
  • Water quality sensors (pH, TDS) reporting on a scheduled or continuous basis
  • RFID, coin and digital payment modes supported on Arosia hardware
  • Solar and battery-backed power configurations supported for off-grid sites

Why it matters

Benefits

One console, every machine

Stop chasing status updates by phone or site visit.

Faster maintenance response

Know a machine is down before customers do.

Reconciled revenue

Cash, RFID and digital payments in one ledger per machine.

Quality accountability

A continuous record of water quality, not a one-time certificate.

FAQ

Common questions

Is this software tied to Arosia hardware only?

The platform was built to run Hydrotec's own Arosia Water ATM units, and that's where it has the deepest integration today. The same data model and Water ATM API are designed to support other Water ATM hardware — talk to us about your specific machines.

What payment methods does the Arosia Water ATM support?

RFID card-based dispensing, coin-based dispensing and digital payment dispensing, per Hydrotec's current product specification.

Can machines run off-grid?

Yes. Arosia units support grid electricity, solar power and lithium-ion battery backup — as deployed at the solar-powered kiosk near Konark, Odisha under a government renewable energy scheme.

How is water quality monitored on a Water ATM?

Where quality sensors are fitted, pH and TDS are logged and reported through the dashboard alongside daily, weekly and monthly usage reports.
