Our history

How it all started

Each East Range Group company was founded as a regional high purity water systems and service company, focused on providing responsive, expert, and local services to facilities throughout their respective geographies. Pure Flow, the oldest of the four East Range Group companies, has built and maintained critical high purity water systems at facilities throughout New England since 1982. Our approach has been to keep the existing staff, brand, and service-centric regional focus of our companies intact. We’ve then invested heavily in our teams, operations, and shared capabilities, enabling each of the businesses to continue growing and thriving.

“If you’re lucky enough to excel at meaningful work you enjoy, you’re very fortunate. But if you do meaningful work you enjoy with people you love, you’ve truly won the lottery.”
