Water Events

CWWA Events

A major part of CWWA’s mandate is to facilitate national dialogue and information sharing.  We achieve this through our publications, the work of our committees, and our national events.

NWWC 2021


Going Virtual
January 11 – February 3, 2022

This is CWWA’s flagship event and THE national conference for Canada’s water leaders.

We attract over 500 delegates from Canada’s water utilities, our private sector partners, provincial and federal governments, academia and the not-for-profit sectors.

While CWWA has hosted specialized events for over 30 years, this ‘consolidated’ event has merged all of the former events into ONE, all-encompassing national event focused on what the senior water manager needs to know.

This annual conference offers a wide-ranging technical program covering almost all aspects of the municipal water sector, while offering the best networking environment for Canada’s water leaders.

As THE national conference for the water utility sector, this event offers the best opportunity for sponsorship and exhibiting your products and services to Canada’s most senior water managers.

The 2021 event will be hosted virtual. We’re still working with our technical committees to figure out exactly how that will look, but we guarantee it’ll be the excellent technical content you’re used to seeing from CWWA.

We are planning on hosting webinars every Tuesday and Thursday from January 11 – February 3, 2022. Topics will be varied, allowing delegates to tune in to just the events they are interested in. Registration and more information on topics, scheduling and sponsorship will be coming soon.

In the meantime members are invited to watch recordings from our 2020 NWWC webinar series.

Window On Ottawa

2022 dates coming soon

The “Window” is CWWA’s signature policy workshop.

Window on Ottawa is CWWA’s signature event focused on federal water policy. It is a unique event where you learn about everything you ever wanted to know about water at the federal level…and were afraid to ask.

The most senior national policymakers from each federal department and agency are invited to the event—not to tell us what they’ve already released, but to tell us what they’re working on now and what is coming next.

The Window on Ottawa is a fascinating forum to engage with these policymakers at a very early stage and leave with an understanding of what to expect as a water leader.


CWWA Workshops & Webinars

Much of our work is very specialized within specific streams that require a focus on specialized topics. Learning and information sharing can sometimes be best achieved though workshops.

In an effort to reach more of our members, and allow more to access critical information in an affordable and timely manner, we will be offering more webinars and electronically-accessed workshops.

A listing of such webinars and all related details can be found here:
