Your meter reading indicates your water consumption in cubic metres (1 m³ = 1,000 l). The figures on a black background represent your consumption in cubic metres, while the red figures indicate your consumption in litres.
Only the figures on a black background are taken into account for your bill.
When you need to give us your annual meter reading, this number on a black background should be sent via your Customer Account or via the indexphone (automatic message service available 24 hours a day).
