A Service-Driven Water Treatment Partner
Over a decade in business. A century of combined team experience. Millions of gallons of water saved. RW Water Services was built on a simple premise: facilities deserve a water treatment partner that shows up, does the work, and tells the truth.
Who We Are
Built on Technical Expertise and Honest Service
RW Water Services is an industrial water treatment company serving commercial, institutional, and industrial facilities throughout the New York metro area. Over more than a decade in business, we have protected thousands of water system assets — from cooling towers and closed loops to domestic water distribution systems and boilers — across hundreds of unique clients ranging from single-building property managers to large healthcare systems and industrial operators.
The experience behind RW goes far deeper than our company's history. Our team brings over a century of combined field and technical experience to every engagement — knowledge earned across thousands of facilities, water systems, and treatment challenges that no textbook covers. That depth is what allows us to diagnose problems quickly, design programs that actually work, and give clients straight answers.
We work with building owners, property managers, facility directors, and mechanical contractors who need a water treatment partner they can rely on — not a vendor who shows up to drop off chemicals and disappear. Our clients stay with us because we understand their systems, communicate clearly, and deliver results.

How We Work
What Sets Us Apart
Service Over Sales
We are a service company first. Our technicians are water treatment professionals, not salespeople. Every recommendation we make is driven by what your systems actually need — not by what generates the most chemical volume.
Technical Depth
Water treatment is a discipline that sits at the intersection of chemistry, microbiology, mechanical engineering, and regulatory compliance. We invest in the technical expertise to get it right — and to explain what we're doing and why.
Accountability
When we take on a client, we take on responsibility for their water systems. That means showing up consistently, communicating clearly, and standing behind our work — not disappearing between service visits.
Long-Term Partnerships
The best water treatment outcomes come from long-term relationships where we understand a building's systems, history, and quirks. We build programs designed to last — and we work to earn the trust that keeps clients with us for years.
Industries We Serve
Expertise Across Every Facility Type
Our programs are tailored to the specific water systems, regulatory requirements, and operational demands of each industry we serve.
