Canadian Water &
Wastewater Association

THE national voice for Canada’s Municipal Water Sector

Advocacy

Events

Committees

CWWA is the professional association for Canada’s municipal water sector and we are THE voice for that sector at the national and international level.  We represent the municipal water and wastewater utilities and the private sector partners that work with them to provide safe drinking water and protect our water resources. 

 

CWWA exists to keep our members informed on national issues concerning our sector, facilitating national dialogue and information sharing, and advocating for our sector on the national and international scene.  We accomplish our mission by working closely with many other organizations and building working relationships with federal departments and agencies.

 

CWWA is a non-profit national body incorporated under the Canada Not-for-profit Corporations Act.  A board of directors, with representation from across the country, directs the mission and goals of the association and oversees the small staff at our headquarters in Ottawa, the nation’s capital.  While our ‘membership’ is at the corporate level, we represent the many thousands of water professionals that work for these member corporations (municipal utilities, consultants, service & product suppliers). The bulk of our work is conducted by these volunteer members through our technical committees and at our national events.

The e-Bulletin

Our national newsletter is produced monthly and distributed to over 5,000 water professionals.  We share our CWWA activity and relevant water news from across the country.

Water Events

See details of CWWA’s national events as well as a calendar/listing? of important water events for our sector.

Window on Ottawa

The Window on Ottawa offers a chance to hear from federal regulators and policy makers about federal programs and initiatives impacting the water and wastewater sector. Originally hosted as an in person event, we’ve started hosting the Window as a series of Lunch and Learn webinars. Watch our webpage for information on upcoming installments in this series.

National Water & Wastewater Conference

This is the flagship event for CWWA and is THE national conference for municipal water leaders.  This conference gathers hundreds of utility leaders, consultants, researchers and regulators to share their experience and innovation and to address the most pressing concerns of our industry.

New Fact Sheets on Cyanobacteria and Microplastics in Drinking Water

CWWA’s Drinking Water Quality Committee has produced two new fact sheets. The first Cyanotoxins In Drinking Water addresses concerns about the potential for cyanotoxins in drinking water, the impacts and health concerns. It provides a general overview of the issue with references to more detailed analysis. The second – Microplastics in Drinking Water will help members and their associated utilities prepare their own responses to questions about microplastics they may encounter from their customers, municipal leaders, political leaders, media, and other concerned stakeholders.
