Shelbyville Celebrates Superintendent Shelly Higdon’s Major Professional Achievement
Shelbyville, IN — The City of Shelbyville proudly congratulates Shelly Higdon, Superintendent of our Water Resource Recovery Facility (WRRF), on passing the Indiana Department of Environmental Management’s (IDEM) Class D Wastewater Operator Certification Exam on June 20, 2025—a significant professional milestone that benefits our entire community.
This is not just a personal achievement—it’s a win for our city.
The Class D certification is the highest level of licensure for industrial wastewater professionals in Indiana. It requires years of experience, in-depth technical knowledge, and a strong grasp of environmental regulations and water treatment science. The exam covers topics such as advanced treatment processes, lab testing, equipment operation, safety procedures, and environmental compliance—critical areas that ensure our city's wastewater systems operate safely and efficiently.
To pass, candidates must demonstrate a mastery of highly complex material and meet strict experience and educational qualifications. It is widely regarded as a difficult and prestigious certification—with only a limited number of operators in the state achieving this level each year.
Our wastewater recovery facility plays a crucial role in protecting public health, preserving our environment, and maintaining clean waterways. Every time you flush a toilet, drain a sink, or run your washing machine, that water is cleaned and safely returned to nature—thanks to a carefully managed, highly technical process that few people ever see.
Shelly’s certification means that Shelbyville is now led by one of the top wastewater professionals in the state, ensuring that our city remains at the forefront of environmental responsibility and regulatory compliance.
“This is more than just a test—it represents years of hard work and a deep commitment to keeping our city safe and sustainable,” said Mayor Scott Furgeson. “We are incredibly proud of Shelly’s achievement, and we know Shelbyville is in good hands.”
With this new credential, Shelly joins an elite group of Class D-certified professionals who are helping Indiana communities run smarter, cleaner, and more efficiently. Her leadership ensures that our facility will continue to innovate and meet the growing needs of our city, all while protecting our natural resources for future generations.
