Canadian Water &
Wastewater Association

THE national voice for Canada’s Municipal Water Sector




Canadian Water and Wastewater Association

The association for Canada’s water professionals

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.

Window on Ottawa & Canadian Water Summit

Ottawa – June 10-12, 2020

 The Window on Ottawa is like no other event.  It is a day focused entirely on federal water policies, programs and legislation.  We refer to it as “everything you ever wanted to know about water at the federal level.”  This year we are teaming up with Water Canada magazine and the Canadian Water Summit to create a full 3 days of water industry dialogue.

National Water & Wastewater Conference

Niagara Falls – Nov 8-11, 2020

 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.
