Welcome to the IRWA

***Registration is STILL OPEN  for our Water Institute***

IRWA has provided over 50 years of service to Indiana Utilities!

Indiana Rural Water Association has many workshops and events throughout the year.  Please visit our EVENTS page to see a complete listing of upcoming Dates and Locations.

Indiana Rural Water Association (IRWA) has a long history of dedication and commitment to addressing the needs of Indiana’s small systems.


In addition to the educational opportunities we offer to operators, managers, and those in responsible charge of utilities, we also have a mutually beneficial teaming arrangement with the American Water Works Association, Indiana Section and the Indiana Department of Environmental Management that has enabled us to serve our industry in new and exciting ways.

IRWA is a membership supported organization. Your dues and fees fully fund our staff and our programs. Our Board of Directors, consisting of seven utilities and two associate members, answer only to you, our membership. Please keep in touch with us regarding ideas for educational topics, how we can better serve the industry, news to be posted on this website, etc.

IRWA recognized the need to enhance communications between utility operators and their boards regarding rules, responsibilities, etc. Our “IRWA Utility Manual for Board Members and Other Decision Makers” is a unique publication that can assist in creating a better understanding of these items and much more. Please click here for more information (PDF).

IRWA has established a water and wastewater operator education fund in honor of the late Marilyn Gambold and her husband, Jack.  Their vision was to provide quality educational opportunities for operators, and this endowment will help ensure their dream lives on.

A number of individuals and companies have given generously to the Gambold Education Fund thus far. Please refer to the Gambold Education Fund button of this website for a listing of those who are helping Marilyn and Jack’s legacy remain strong.
