The International Water Association (IWA) uses an anniversary year membership system which means:
- when you join the Association, your membership starts from the day in which the payment for your membership fee is received.
- when you renew your membership, the new cycle starts from the day on which your previous membership period ended.
If you are a new member and the payment for 1-year membership is received on 6 January 2019, your anniversary date will be 6 January therefore your membership will run until 6 January 2020. When renewing your membership, the new membership cycle will also start on 6 January. This means that if you renew after your anniversary date, your membership as well as your benefits will be backdated to your anniversary date.
