🎉 Happy Retirement, Mark with Greene County Sanitary Engineering Department! 🎉

Greene County would like to congratulate the Director of Sanitary Engineering, Mark Chandler, on his retirement and celebrate an incredible 34½-year career in the public utility industry.

Mark’s journey began in 1991 with the Village of Byesville, following several years working in the coal mines of eastern Ohio. From there, he grew into a certified Ohio EPA water and wastewater operator and served as Wastewater Superintendent until 2009. He then spent 10 years as Operations Superintendent for the Delaware County Regional Sewer District before bringing his expertise to Greene County in 2019 as Deputy Director of Operations & Maintenance. In July 2023, Mark was promoted to Director, where he has led with knowledge, dedication, and integrity.

💬 What are you most proud of during your time with Greene County?
The start up and Ribbon Cutting Ceremony of the Northwest Regional Water Plant.

💬 What will you miss the most?
Working with my co-workers and customers.

💬 What are you looking forward to in retirement?
Relaxation, traveling, and spending more time with family.

Throughout his career, Mark has been passionate about mentoring others and sharing his knowledge in operations, budgeting, planning, and system design. Above all, he hopes his legacy is defined not just by the work he’s done, but by the relationships he’s built and the people he’s served.

We are so grateful for his service and all that he has contributed over the years, and we wish him the very best in his well-deserved retirement. Enjoy this next chapter, Mark—you’ve earned it! 💙

Greene County Sanitary Engineering would like to congratulate our Director, Mark Chandler, on his retirement. Mark has been in the public utility industry for 34 ½ years. He started in the Village of Byesville in 1991, after working several years in the coal mines of eastern Ohio.
As a certified Ohio EPA water and wastewater operator, Mark advanced to be Wastewater Superintendent for the Village until 2009. Aspiring to advance his career in the industry, he then accepted the role as Operations Superintendent for the Delaware County Regional Sewer District where he remained for 10 years.
He came to Greene County Sanitary Engineering in 2019 where he served as the Deputy Director of Operations & Maintenance. In July 2023, he was promoted to Director where he has served for the last 3 years.
Mark has a vast understanding of operating a public utility from the ground up. He has devoted much of his career to mentoring co-workers in operational processes, budgeting and planning, and designing collection systems, and O&M. Mark wants his legacy not to be for the work he has done throughout his career, but rather for his appreciation of the people he has served—employees and customers alike.
Thank you Mark for all of your service!
