Why Join Us

Effectively the 60th SWMM users group meeting, this is the 33rd meeting to be held in Toronto. The ICWMM brings together professionals from around the world to exchange ideas on current practices and emerging technologies in water management. Emphasis is on state-of-the-art computer modeling for resolving water quantity and quality problems in stormwater, wastewater, watershed and water distribution systems.

Presentations are of a very high standard and the atmosphere is informal and relaxed. And, by accepting abstracts up until the last minute, a spontaneity is achieved which gives the conference its special character.

You can earn up to 2 CEUs by attending this conference.

  • Civil and environmental engineers, landscape engineers and architects
