A water ATM is an RO plant with a dispensing kiosk that sells purified water by the litre against a prepaid card, coin or UPI payment. It lets a housing society, village, campus or municipality provide purified drinking water and recover the running cost from users instead of from a maintenance fund.
It has three parts: the purification plant (sized in litres per hour to the daily demand), the storage tank, and the dispensing unit with its payment and metering system. The purification side is a standard RO plant with UV; the dispensing side is where water ATMs differ — card management, tariff setting, remote monitoring and anti-tamper design.
Plan capacity from expected daily litres, not from the number of users: peak hours (morning and evening) decide tank size and dispensing points.
What to specify
- Payment method: RFID card is the most common for societies; coin and UPI suit public locations.
- Tariff control and user management from the operator's dashboard.
- Hygiene: UV after storage, food-grade tanks and a closed dispensing nozzle.
- Water quality display (TDS) at the kiosk builds user trust.
Installation, commissioning and service response
Commercial buyers are buying uptime, so the commercial terms matter as much as the equipment specification. Insist on these being written into the purchase order rather than discussed verbally.
- Site survey and feed-water analysis before the final quotation — never accept a specification produced without a water report.
- Defined commissioning scope: civil and electrical prerequisites, who supplies what, and a documented performance test at handover.
- Written service response times, with escalation, and clarity on whether spares are held locally.
- Operator training and a laminated SOP left on site, so routine flushing and cartridge changes do not depend on one person.
- Warranty terms stated separately for membranes, pumps, vessels and instrumentation, because they differ.
What a quotation includes
- Daily demand and peak-hour assessment
- RO + UV plant sized in LPH
- Treated-water storage
- Dispensing kiosk with card / coin / UPI payment and metering
- Remote monitoring, AMC and operator training
Why specify with us
Low total cost of ownership
High-rejection membranes, correctly sized pre-treatment and efficient pumps reduce power draw, consumable spend and reject volume. We quote five-year operating cost alongside capex, because that is the number that actually matters.
Heavy-duty SS-304 / SS-316 build
Corrosion-resistant stainless chassis and wetted parts engineered for continuous 24/7 duty, with SS-316 specified where chlorides or process chemistry demand it.
Rapid on-site servicing & AMC
Pan-India installation and service, with written response times and escalation in the AMC rather than verbal assurances — because plant downtime, not the repair, is your real cost.
Custom TDS tuning
Systems engineered against your actual water analysis — brackish groundwater, municipal supply or heavy borewell input, including high-TDS configurations for 3,000+ ppm feed.
Treatment architecture
- 1
Pre-treatment module
Multigrade sand and activated carbon filtration strips suspended solids, turbidity and chlorine that would otherwise oxidise the RO membrane.
- 2
Softening / antiscalant dosing
Protects membranes from calcium and magnesium scaling. On hard feed water this stage is not optional — it determines membrane life.
- 3
High-pressure RO module
Heavy-duty booster pumps drive feed water through industrial spiral-wound membranes at 12-18 bar in an array sized for your recovery target.
- 4
Post-treatment disinfection
UV disinfection and ozonation, with mineral dosing where potable taste and consistency matter.
- 5
Microprocessor / PLC controls
Auto start-stop on tank level, dry-run protection, high and low pressure cut-offs, and timed membrane flushing — with data logging on industrial plants.
