You can find your customer number in My Waternet for tap water, on your tap water bill or on your bank account statement for your tap water installments.

Are you moving to or out of Amsterdam? Then you need to take action for your tap water.

View our bank account numbers. Please use a different one for each service: your tap water and water authority tax.

You cannot change the name on the tap water account yourself. The new customer must register himself. After that you will automatically receive a final bill.

If you moved out of The Netherlands, you may still have to pay an outstanding amount. Please check what kind of bill you received: waterschapsbelasting (water authority tax) or drinkwater (tap water).
