Registration is not required at «My DEYAR». Once you log in using your Taxisnet credentials, any water meters already registered under your VAT number will appear. You will need to update the details for the meters where you are the user and reject the meters where you are not the user. If a water meter does not appear, you will need to «add it manually». Once you have completed the process of updating your details, you will have access to the «My DEYAR» applications.
