Water Treatment Plant Engineer intern

“I most enjoyed hands on learning with the employees. The expectation was learn through making your own graphs and do your own research. I decided to work on the plant. On the plant, I assisted in preventative maintenance duties and aided in crucial tasks such as rewiring a motor from low voltage to high voltage, putting the parts together to replace old valves and light fixtures, and learning about projects that are currently being built on the plant. ”
