How the system works
Each subscriber is issued a smart card. They load credit onto the card and present it to the meter; the credit transfers to the meter and decreases with consumption. When it runs out, the motorised valve shuts off the water automatically.
Reserve credit
Before credit is fully exhausted the system switches to a reserve amount and briefly reopens the valve, so no subscriber is cut off without warning.
What management gains
- Collection problems and overdue receivables disappear
- No more door-to-door index reading
- Leaks and unauthorised use are logged
- Consumption reports make water loss traceable
