On your water bill

A briefing note on tap water quality is attached annually to the water bill.

Depending on the billing method of your accommodation, this invoice can be sent directly to the tenant or to the syndic of co-ownership.

If you are a tenant and you do not receive the water bill, you can obtain this note from your landlord or the trustee. If you do not know the trustee, his contact information is usually displayed in the common areas of the building.
