The implementation of tariffs and fees in water resources management is subject to numerous requirements, which result on the one hand from water-legal and on the other hand from statutory regulations. Supporting municipalities and water associations in the development of models for the allocation of costs in the calculation of fees and tariffs, we focus in particular on the distribution of burdens according to the polluter-pays principle.
The scientific support of the development and optimization of water tariffs and fees begins with an analysis of the current situation and the determination of the need for action. For this purpose, existing data are specifically processed and evaluated. It is necessary to investigate whether water management, technical or legal requirements and framework conditions and thus cost and usage structures have changed. We suggest fee and tariff models, in particular for the areas of wastewater disposal and water management, and support municipalities and water associations by conducting working groups and informing citizens and members.
A regular review of the assessment models against the background of a polluter-pays cost allocation can make a valuable contribution to an overall sustainable water management.
