As stated on the website:

The Irrigation Show is a program of the Irrigation Association, a non-profit 501(c)(6) organization dedicated to promoting efficient irrigation.

Unlike for-profit trade shows, proceeds from the Irrigation Show support IA initiatives to benefit members and the irrigation industry by:

• Improving industry proficiency through continuing education.
• Recognizing and promoting experience and excellence with professional certification.
• Serving as a centralized clearing house for irrigation research and innovations.
• Educating the public on sound irrigation practices and water management.
• Lending expertise to water-use public policy at the local, state, regional and national level.
