Wastewater Treatment Service Market Size

Global Wastewater Treatment Service Market size was valued at USD 58.6 billion in 2023 and is poised to grow from USD 62.64 billion in 2024 to USD 106.83 billion by 2032, growing at a CAGR of 6.9% during the forecast period (2025-2032).

The rapid population growth and urbanization, the high-water treatment standards, the increasing demand for new sources of water, the increasing importance of public health and water quality, and the increasing incidence of waterborne diseases are some of the drivers of the global wastewater treatment service market growth. Furthermore, freshwater scarcity has heightened the need for recycling and reuse of wastewater, triggering demand for high-level treatment services like membrane filtration, biological treatment, and chemical processing.

To address water scarcity, the Council on Energy, Environment, and Water (CEEW), in association with the 2030 Water Resources Group, is predicted to improve wastewater management in India and enhance private investments in building wastewater treatment plants. Moreover, another key trend driving the growth of the wastewater treatment service market include the growing investment in wastewater plants, particularly in emerging economies where the rapid growth of cities is swamping existing water treatment facilities. There are nearly 1,944 municipal wastewater treatment plants in China's cities and 1,599 municipal wastewater treatment plants in China's counties. The plants have treatment capacities of 140 and 29 million cubic meters per day, respectively.

How is IoT Revolutionizing Wastewater Treatment?

By continuously monitoring water quality parameters, flow rates, and plant performance, the Internet of Things (IoT) and smart monitoring technologies are revolutionizing wastewater treatment services. Preemptive detection of anomalies, minimizing manual interventions, and maximizing chemical dosage and energy efficiency are facilitated by cloud platforms and smart sensors. Data-driven decision-making enables this not only to enhance operational performance and regulatory conformance but also to prolong equipment life and minimize environmental footprint.

• For instance, Veolia North America implemented an Internet of Things-based remote monitoring system at numerous United States municipal wastewater treatment plants in March 2024. The system monitors flow rates, chemical dosing, and pollutant levels in real-time via cloud-linked sensors and predictive analytics. The rollout proved the practical benefit of intelligent monitoring in raising wastewater treatment effectiveness and sustainability through lowering operating expenditures by 12% and promoting regulatory compliance through facilitating immediate overflow or contamination breach alerts.
