“I have been honored to work with such a great group of people and commissioners at TVWD,” said DiLoreto. “I couldn’t think of a better way to finish up my 37 years in the public sector. I leave the district in good hands, and I’m confident they will continue to be a leader in the water industry.”

DiLoreto has worked in the public works field for 34 years, 17 years as a public works director and city engineer. He holds a bachelor of science degree in civil engineering from Oregon State University and a master’s degree in public administration from Portland State University. DiLoreto is a fellow in the ASCE, and was named the 2005 ASCE Government Engineer of the Year. In 2003, he was inducted into the Oregon State University Academy of Distinguished Engineers.

The TVWD Board of Commissioners named Mark Knudson as the new CEO.

“I look forward to taking the reins and leading TVWD during the addition of a new water supply for the district and the region,” said Knudson. “Greg has been an excellent CEO and is leaving the district as a respected and award-winning organization — I have large shoes to fill.”
