The purpose of WEF’s Industrial Wastewater Committee (IWWC) is to be a resource on industrial wastewater treatment, design, management, operation, and maintenance, as well as the promotion and improvement of industrial treatment technologies.

The IWWC was established in 1943; revised October 1994; revised in 1998, merged with Hazardous Wastes Committee and became Industrial Wastes in September of 2002; and changed their name to Industrial Wastewater in January 2010.

The Committee is involved in a number of activities to improve the technology of industrial water and wastewater treatment, recycle and reuse. The committee meets in person twice a year at: the WEF Mid-year meeting in February and at WEFTEC in October, in addition to having bi-monthly conference calls to continue progress throughout the year. The committee provides technical information exchange; professional networking opportunities; communication of regulations, and policy and guidance. Programs addressing industrial water, wastewater and hazardous wastes treatment, disposal, prevention, remediation, reuse, and minimization are developed by the committee.

The Committee’s overall charge includes the following:

  • Development and support of conferences, workshops, seminars, training, and technical sessions.
  • Development and support of publications related to industrial wastewater treatment topics.
  • Development and support of awards in the industrial wastewater treatment area.
  • Development of public outreach materials expressing technical industrial wastewater treatment issues.
  • Partnering with other organizations and committees in development of industrial wastewater treatment activities.

Newly Released "Pulp and Paper: Temperature Modeling in Large Basins" Factsheet!

The WEF IWWC Chemicals and Manufacturing Subcommittee is excited to announce the release of their "Pulp and Paper: Temperature Modeling in Large Basins" factsheet.  

60+% of wastewater produced by the Pulp & Paper industry is treated using large basins. Temperature impacts performance.  This factsheet presents two existing basin thermal models, compares the strengths and weaknesses of both and provide guidance for selection depending on project specifics.
