Future-oriented Technologies and Concepts for an Energy-efficient and Resource-saving Water Management (ERWAS)

Joint Research Projects

Within the framework of the ERWAS funding measure, the BMBF is supporting twelve joint research projects with more than sixty partners from science and practice. Approaches to solutions for a more efficient and economical use of energy are to be developed, and ways smoothed to making better use of existing resources for generating energy in the water management sector. In order to ensure the transfer of the project results into practice and to align the research and development work to the needs of users, stakeholders from science, business as well as from the municipalities and states work together in all joint research projects.

In addition to the joint research projects the network and transfer project ERWASNET is being carried out.

Project coordination:
Anett Baum
DWA - German Association for Wastewater, Water and Waste

Tuttahs & Meyer Ingenieurgesellschaft mbH

ERWASNET supports the Federal Ministry of Education and Research and the Project Management Agency Karlsruhe in realizing the funding measure. Main tasks of the networking and transfer project are to support internal communication and networking of project participants, identification and development of cross-cutting issues and to support the joint research projects in realizing their dissemination obligation. Furthermore, ERWASNET is to develop tools for knowledge transfer in order to support the implementation of research results into practical use.
