Environmental and Water Resources Institute


The Environmental and Water Resources Institute (EWRI) was created on April 6, 1995 as a technical subcommittee of the Arizona Society of Civil Engineers (AzSCE).

Committee’s Mission:

“Provide an open forum for discussing technical water resource issues within Arizona.”

Objectives of the EWRI include:

  • Conducting technical education programs on water resource topics
  • Sponsoring activities that serve the need of water resource professionals
  • Furthering public understanding of the field of water resources, hydraulics, and environmental engineering
  • Coordinating local water resource related functions with other related organizations
  • Review and comment on state and local legislation related to water resource issues


The Arizona Chapter of EWRI meets the third Thursday of most months to hear presentations and discuss technical water resource issues, studies, and projects.

Currently, all presentations are virtual, but we are working towards having at least one in-person meeting throughout the year. 

To attend a virtual meeting, please sign up below to become a free member of EWRI.
