De Watergroep is a member of the International Water Association, the worldwide network of water professionals. Within this organisation, De Watergroep is part of the specialist group on statistics and economics. 

Every 2 years, this working group compiles the brochure "International Statistics for Water Services". This brochure contains the results of an international study of water tariffs and tariff structures. It includes, among other things, an overview of tariffs, the origin of drinking water, consumption, population figures, regulations, etc. This study is fully coordinated within De Watergroep. Since 2016, the paper version has been replaced by a digital version. Click here to view the website with the 2016 statistics.
