Our companies

Shared vision, resources, and expertise

We believe in a culture of front‑line autonomy paired with best‑in‑class shared resources.

A group effort

Our team approach

Our front-line teams are empowered with high levels of autonomy, accountability, and authority. Each geographical area we serve, with its distinct feed water sources, end-user industry types, and adherence to local policies and regulations, presents unique high purity water challenges. To proactively serve our thousands of customers and their mission-critical high purity water systems – no two of which are identical – a culture of decentralized decision-making authority is vital.

Complementing this commitment to local autonomy, East Range Group companies benefit from centralized resources in applications engineering, finance, accounting, HR, legal, IT, and software, as well as key supplier relationships, that are shared across the companies.

Pairing front-line empowerment with expert shared services is critical to delivering the highest quality high purity water services in the industry.
