Wastewater Treatment Services Market to Reach $92.74B by 2030
The wastewater treatment services market is expected to grow from USD 66.53 billion in 2025 to USD 92.74 billion by 2030, reflecting a compound annual growth rate (CAGR) of 6.87%, according to the report “Wastewater Treatment Services Market by Service Type, End-Use Industry, and Region – Global Forecast to 2030.”
This growth is attributed to a rise in environmental concerns, rapid urban development in major economies, and the tightening of environmental regulations. As industrial activity expands in tandem with global population growth, the volume of wastewater from domestic, commercial, and industrial sectors is also increasing. This has created a strong need for advanced treatment services to prevent environmental damage and protect public health.
At the same time, awareness about water scarcity is encouraging greater adoption of wastewater recycling and reuse technologies. This transition is particularly vital in regions suffering from water stress, where circular water practices are becoming a necessity for long-term water resource management.
