The IAWR operates independent measuring networks in bodies of surface waters through its members:
- ARW Arbeitsgemeinschaft der Rheinwasserwerke e. V.,
- AWBR Arbeitsgemeinschaft Wasserwerke Bodensee-Rhein and
- RIWA Vereniging van Rivier Waterbedrijven
Based on these results, independent scientific studies and research projects are carried out regarding issues related to the protection of resources and drinking water in the Rhine basin area. International experts from individual waterworks cooperate closely in expert committees.
The IAWR’s demands – formulated in memoranda and standpoints – are aimed at representatives and decision makers in industry and politics at EU and national levels. Additional external contacts are government bodies as well as decision makers in the field of water management.
