IWA Specialist Groups
The International Water Association (IWA) is a professional membership association dedicated to the advancement of the science and practice of water pollution control and water quality management worldwide. IWA Specialist Groups provide a sound structure of networks for specialists from around the world to share information and skills, and make good professional and business contacts. Members of IWA can join up to five Groups.

News: The 6th international conference on sewer processes and networks has been announced. The conference will held in Surfers Paradise, Australia, 7-10 November 2010. More info can be found at the conference webpage.

Sewer Systems & Processes Working Group
This Working Group was formed in 1997 under the umbrella of The International Water Association (IWA) and The International Association for Hydraulic Research (IAHR) Joint Committee on Urban Drainage (link), as a group with activities regarding physical, chemical and biological aspects of sewers.

Objectives and Scope
To disseminate information about sewer systems, in particular to coordinate research and development activities relating to physical aspects (structure and layout), physical processes (hydraulics and transport of solids), chemical and microbial processes (pollutant occurrence, transformations and interactions), and interactions where appropriate with sources and destinations such as environment (via overflows) and treatment plants. Activities will relate to system design, operation, rehabilitation/renovation, maintenance and control, and will overlap to some extent with IWA specialist groups. However, the group will act as a focus for (in-sewer) process activities. See also the SS&PWG statutes.

Committee
The Committee comprises of up to two members from each country who are actively involved in some aspect of sewer systems and processes. The requirement for membership of the committee is to be active within the area of the SS&PWG and that the committee member truly represents his or her country; i.e. knows what goes on. A member can be practitioner as well as university employed. Ideally one member should be working with the physical aspects of transport and one with chemical and microbial processes in sewer systems.
