J. CollierProject Leader - Water Corporation

I wanted to take a moment to express my appreciation for the excellent work your team did during the hot-tapping operations in Allanooka. The quality of work and professionalism exhibited by everyone on the team was truly impressive. We were particularly impressed with the care and precision with which all equipment was operated.
