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 and the benefits that come with it will be backdated to your anniversary date.
