Overview
Water & Wastewater Treatment Equipment Manufacturing covers the pumps, filtration and membrane systems, UV and disinfection equipment, and treatment technologies used to purify water and treat wastewater for municipal and industrial customers. It is led by water-technology majors (Xylem, Pentair, Veolia/Evoqua, Ecolab) supplying utilities, industry, and commercial buildings.
Demand is driven by aging water infrastructure, tightening regulation (PFAS, lead, nutrient limits), water scarcity and reuse, and industrial-process water needs — durable, regulation-backed growth. It is a consolidating, technology-rich segment and an active M&A arena (e.g., Xylem's acquisition of Evoqua) around water technology.
Market snapshot
Water-treatment equipment spans pumps, filtration, membrane, and disinfection across several NAICS codes (e.g., 333911/333999/333413) and is not separately disclosed by the Census Bureau, so the segment is not separately sized here.
