IWA Membership and HIC/LIC Classification

Authors do not need to be members of IWA to participate in the conference. However, IWA members have access to a range of benefits including significant registration discounts. IWA members also receive The Source Magazine and benefit from additional discounts on IWA publications and all IWA events.

IWA operates a High / Low Income Country classification for its membership and registration fees. The HIC / LIC classification is based on your country of residence and not on your country of origin.

Participants having their habitual residence in low and middle-income countries receive a discount on the registration fee.

Please visit the 2025 Country Classification Table to confirm your HIC, UMIC, LMIC or LIC status according to IWA’s four-tier country classification based on the World Bank classification. Delegates from UMIC, LMIC and LIC countries will be regarded as Low Income Country (LIC) delegates for ecoSTP2027 registrations.
