My organization is already member, how do I get access to private contents?

National Associations members of EWJI have up to 10 users, included with their membership.

Specialized companies members of EWJI have up to 5 users, included with their membership.

If your organization (association or company) is already member of EWJI (see the member list), contact your delegate to request a user.

Why do I have to pay?

EWJI is a non-profit organization, but to develop its activities needs resources.

These resources come from the membership fees and any other sources of income, including subscriptions to the private contents of the website.

If you are an independent professional or part of a specialized organization related with the water jetting applications mentioned above, you can support EWJI through membership or a paid subscription.

If you are a professional from a Public Administration or from another organization not linked directly to water jetting, we also offer partnership agreements. When you become a partner of EWJI, you will receive one Premium Subscription free of charge.


Can I purchase access only to a specific content?

Sorry, but no.

Technically it is very complicated to give specific user access to specific contents, so we decided to create user levels.

Once registered as free user,  you will be able to upgrade your level and have access to the EWJI contents, as listed on this page.

If you want any of the EWJI printed publications, buy them directly (while we have stock).
