James Clifton

James (Jim) Clifton holds a Bachelor of Arts and Master of Science in biology. He was initiated into the wastewater field in 1980 by starting up a facility upgrade in Seaford, Delaware. In 1985 Mr. Clifton joined the staff at the University of Florida’s Center for Training Research and Education for Environmental Occupations (TREEO), shortly after he obtained his Florida Class A Wastewater Treatment Operator certification. Initial responsibilities involved providing training and technical assistance to small non-compliant municipal wastewater treatment facilities throughout Florida. The position evolved to developing and delivering new continuing education training programs for wastewater personnel.

In 1997 Mr. Clifton left TREEO to assume the superintendent position in Manchester, Connecticut. In 2000, with the prospect of participating in the design, construction, and operation of a nitrogen removal facility, he accepted the superintendent position at the Simsbury, Connecticut facility. Mr. Clifton retired from day-to-day operations in 2013. While in Connecticut he obtained a Class IV Wastewater Operator Certification and served on the Connecticut Department of Environmental Protection’s Certification Advisory Committee as the Educator for 14 years.

In 2013 Mr. Clifton received the William D. Hatfield award from the New England Water Environment Association and the Wastewater Treatment Plant Operator Excellence Award from the New England EPA.

However, Mr. Clifton has not been able to fully relinquish participation in a profession and organization he loves and stays involved by contributing to TREEO’s mission as a trainer.
