How to read a water bill
The water field is straightforward: use metered water consumption in m³. Ignore charges and service fees.
Find the metered water consumption in cubic metres, map it to Water consumption (m³), and ignore wastewater fees or total EUR charges.
Exact mapping
What to extract and where it goes
Look for
- Metered water consumption in m³
- The billing period that matches the reporting year
- Any total or annual consumption summary line
Enter into
- Water consumption (m³)
Unit
m³
If missing
Leave Water consumption (m³) at 0 and continue.
Do not use
- Total amount in EUR
- Wastewater or sewage charge
- Service fees or other utility charges
Visual mapping
Find the line on the document, then place it in the right field
This is the exact behavior we want from both users and assistants: identify the operational quantity, ignore the money amount, and map the quantity into the matching field.

If the supplier issues multiple bills during the year, add the water consumption in m³ for the reporting year.
Recommended workflow
How to use this category correctly

Step 5
Ignore wastewater charges, service fees, and total price in EUR.
Assistant prompt support
How an assistant should guide the user in this category
Ask the user for the water bill or annual utility statement.
Extract the metered water consumption in m³.
Map that value to Water consumption (m³).
If there are multiple water bills, tell the user to sum the annual m³ values.
Ignore wastewater fees, service fees, and total invoice amount in EUR.
Structured FAQ
Questions an agent or user might still ask
What if the water provider issues several bills during the year?
Add the m³ values from all bills that belong to the reporting year and use that annual total in Water consumption (m³).
Can I use the total amount in EUR if the m³ line is missing?
No. If you do not have a defensible m³ figure, keep Water consumption (m³) at 0 until you have the actual usage value.
