The global water and wastewater treatment equipment market is experiencing significant growth, driven by increasing environmental awareness, stringent regulations, and the pressing need for sustainable water management solutions. Valued at approximately USD 53.15 billion in 2021, the market is projected to reach USD 84.43 billion by 2030, expanding at a compound annual growth rate (CAGR) of 5.4% from 2022 to 2030.
Market Overview
Water and wastewater treatment equipment encompasses a wide array of technologies designed to treat, purify, and recycle water. These solutions remove biological, chemical, and physical contaminants, making water suitable for industrial, agricultural, and domestic use or compliant with environmental discharge standards. The sector includes solutions such as sedimentation tanks, membrane filtration technology, UV disinfection, aeration systems, and sludge treatment systems.
Growing urbanization, rising industrial output, and increasingly stringent water quality regulations across both developed and emerging economies are key accelerators of market growth. Climate change and depleting freshwater sources are further driving the global urgency for sustainable water infrastructure.
Market Segmentation
The water and wastewater treatment equipment market can be segmented based on equipment type, application, and end-use sector.
By Equipment Type
Filtration Equipment: Includes sand filters, multimedia filters, and activated carbon systems. These are commonly used in pre-treatment and primary stages of purification.
Membrane Separation Equipment: Technologies such as reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF), and microfiltration (MF) fall under this category. These systems are widely adopted in both municipal and industrial sectors.
Disinfection Equipment: Includes UV systems, chlorination units, and ozonation devices that are essential for pathogen removal.
Sludge Treatment Equipment: Solutions for thickening, dewatering, and digesting sludge, making it safer for disposal or reuse in energy production.
Others: Includes aerators, screens, and sedimentation tanks used in early stages of treatment.
By Application
Municipal Water Treatment: For supplying potable water and treating urban sewage.
Industrial Effluent Treatment: Used across manufacturing, mining, chemical, and food sectors for managing process water and waste streams.
Agricultural and Rural Systems: Used for irrigation water recycling and treating agricultural runoff.
By End-Use Sector
Residential
Industrial (Chemicals, Food & Beverage, Pulp & Paper, Oil & Gas)
Commercial and Institutional (Hospitals, Schools, Government Buildings)
