At the same time, water scarcity is pushing governments to prioritize wastewater reuse and resource recovery.
Urbanization remains a major growth catalyst, especially in emerging economies where population expansion is placing heavy strain on existing water systems. The municipal segment currently dominates the market, supported by public investments in sewage networks and treatment facilities. Industrial wastewater treatment follows closely, particularly in sectors such as chemicals, pharmaceuticals, food processing, and power generation, where compliance and environmental stewardship are business imperatives.
Technological innovation continues to unlock new opportunities. Advanced oxidation processes, membrane bioreactors, and digital monitoring tools are improving operational efficiency while reducing environmental impact. However, high capital costs and complex regulatory frameworks in certain regions can still slow project implementation.
