The JCUD hosts several working groups around the major teams of research in the field of Urban Drainage. These working groups organise events including international conferences and (online) workshops, write position papers, and enable international collaborations in the respective fields. Below, more information can be found via the respective website and links to contact the committees are provided.
IWGDM aims to further research and disseminate knowledge and technology related to data collection and modelling of urban drainage systems. This working group organizes a conference known as the International Conference on Urban Drainage Modelling (UDM).

Its aim is to help the international advances in the field of Real Time Control (RTC) by disseminating knowledge and technologies. The IWGRTC will organise workshops during international events and create a platform where a quick overview of RTC in the field of Urban Drainage can be found.

The Sewer Systems and Processes Working group aims to disseminate information about sewer systems and coordinate research and development activities relating to the physical aspects, physical, chemical, and microbial processes, and interactions with sources and destinations (treatment plants or the environment). Every three years, the working group organises an international conference (SPN).

The Urban Drainage Asset Management working group has its roots in the series of European research workshops, but has expanded to the rest of the world since. The working group continues to organize these EURO-SAM workshops, but also produces position papers and organize dedicated sessions on asset management at international conferences. It aims to further the research and disseminate knowledge, tools and practices relating to the asset management of all urban drainage assets, that is to say mostly (but not limited to) storm water control measures and pipes. Asset management encompasses approaches such as monitoring, condition and performance assessment, deterioration modelling, decision support, operation, maintenance and rehabilitation techniques and planning.

The International Blue Green Infrastructures Working Group (iBGi) has its roots in the previous WSUD/SOCOMA. The iBGi aims to continue this legacy and bridge state-of-the-art storm water control measures with contemporary perspectives and multidisciplinary efforts. Our mission is to unite the urban drainage and climate adaptation community—comprising both practitioners and researchers—to foster stronger connections, exchange innovative ideas, integrate educational initiatives and generate and transfer new knowledge collectively at a global level, providing consistency and stronger guidance in a field that has been fraught with ambiguity. The iBGi will strive to ensure that the latest research findings and ongoing efforts promote a unified understanding of this rapidly growing field.

The International Working Group on Emerging Contaminants (IWGEC) aims to exchange research results, knowledge, data, and guidelines on emerging contaminants (micropollutants, microplastics) in urban water systems. The working group focuses on the following research areas: contaminant characterization, monitoring and data reporting, contaminant sources and levels in urban systems, contaminant management and treatment (blue-green and grey systems), and environmental and health risk assessment.

The international working group on Urban Rainfall (IGUR) aims to disseminate knowledge, technology, and existing procedures relating to the measurement and processing of rainfall and snow data in urban hydrology to practitioners and researchers. It also aims to coordinate and pursue activities related to all aspects of rainfall-related phenomena and urban hydrology.
CHAIR

The International Working Group on Urban Streams (IWGUS) aims to promote joint research and academic exchange among the JCUD community. This includes the dissemination of knowledge and technology related to urban stream restoration, including urban watershed environmental planning and management, urban runoff control, and LID BMPs.
