In most residential apartments in India, water billing works like this — the facility team reads a bulk meter at the main inlet, divides the total by the number of flats, and sends everyone the same bill. It does not matter if Flat 401 has four people and runs the washing machine twice a day, or if Flat 204 has one person who travels frequently. Everyone pays the same. Nobody knows how much they actually used. Nobody can prove anything. At Rainbow Vistas in Hyderabad, that system is over. EnSmart integrated 345 digital water meters — one for domestic supply and one for borewell supply in every flat — into the Smart Nova Water Billing and Management platform. Every flat now has its own consumption record. Every bill is based on actual usage. Every resident can see exactly what they used and exactly what they owe. Phase 1 is complete. More phases are coming.
Smart Nova Water Billing & Management. 345 digital meters. Domestic and borewell — both tracked. Phase 1 live at Rainbow Vistas, Hyderabad.

That is how water billing works in most residential apartments today. At Rainbow Vistas, the facility team faced exactly this problem. The building had a main water inlet, a borewell supply, and hundreds of flats consuming different amounts of water every single day. But there was no flat-level meter, no individual consumption record, and no way to know which flat was using 500 litres a day and which was using 5000. The facility team estimated. Residents disputed. Arguments happened every billing cycle. High consumers paid the same as low consumers. Low consumers felt cheated. The facility manager had no data to resolve any complaint. Water was being consumed, billed, and disputed — all without a single accurate number anywhere in the system.
The result:
Inside the full case study, you'll see:
| Year | Milestone |
|---|---|
| Phase 1 | Planning & Survey — All flats in Phase 1 mapped, 345 digital water meter locations confirmed, domestic and borewell supply points identified, Smart Nova architecture designed for the full phase |
| Phase 1 | Meter Integration — All 345 digital water meters connected to Smart Nova, domestic and borewell meters paired to individual flats, live readings verified for every unit |
| Phase 1 | Billing Configuration — Flat-wise billing set up in Smart Nova, unit rates configured for domestic and borewell supply separately, billing cycle and report templates built and tested |
| Phase 1 | Testing & Commissioning — Full billing cycle tested end to end across all 345 flats, consumption calculations verified, flat-wise reports generated and confirmed accurate |
| Phase 1 | Go Live — Facility team trained on Smart Nova Water Billing platform, first live billing cycle completed, residents receive flat-wise water bills for the first time — Phase 1 complete |
| Phase 1 | Coming soon — Smart Nova platform ready to onboard additional phases of Rainbow Vistas as they come online — same system, same accuracy, same transparency extended to every new flat |

Residents accepted estimated bills because there was no alternative. Facility teams absorbed the disputes because they had no data to resolve them. High consumers benefited at the expense of low consumers, and nobody could prove anything either way. Rainbow Vistas in Hyderabad chose to change that. By deploying Smart Nova across 345 flats — with separate domestic and borewell metering for every unit — they gave every resident their own water story. A story told in actual readings, actual consumption, and actual bills. No assumptions. No guesswork. Just clear visibility into one of the most basic and important utilities in a home. Phase 1 is complete. The data is flowing. The bills are accurate. And as more phases of Rainbow Vistas come online, Smart Nova will scale with them — bringing the same fairness, the same transparency, and the same accountability to every flat in the complex. That is what smart water management looks like. And Rainbow Vistas is leading it in Hyderabad.
