The Niersverband was founded by Prussian law of July 22, 1927 with the aim of regulating water runoff, limiting or avoiding frequent floods, and purifying wastewater in the association area . At that time, the Niersverband area belonged to the Rhine Province of Prussia . The model for the establishment of the Niersverband was the Emschergenossenschaft , which existed since 1904. The Ruhrverband and the LINEG drainage cooperative on the left bank of the Rhine were also founded based on this model, as well as the Lippeverband in 1925 and later the Wupperverband (1930).
With the Niers Association Act (NiersG) of December 15, 1992, the state of North Rhine-Westphalia reformulated the legal basis of the association. The tasks of the Nierverband were specified and expanded to include the management of groundwater and the renaturation of water bodies. In addition, self-administration was reorganized.
The Niersverband is a self-governing body under public law . It represents the interests of its members within the framework of the legal requirements. Organs of the Niersverband are
- the association assembly
- the association council

The members send the delegates elected by electoral groups to the association assembly, which meets at least once a year. The elected delegates are complemented by members of the Chamber of Agriculture.
The association council has the function of a supervisory body. It consists of 15 members. Five of these members are employee representatives.
The board takes care of the day-to-day administration and is the legal representative of the association.
