Press Release

United States Secondary Water And Wastewater Treatment Equipment Market is Expected to grow at a robust CAGR of 3.89% through 2030F

The increasing United States secondary water and wastewater treatment equipment market is driven by rising adoption of membrane bioreactor (MBR) systems, increasing integration of automation and smart monitoring during the forecast period 2026-2030F.


According to TechSci Research report, “United States Secondary Water And Wastewater Treatment Equipment Market – By Region, Competition, Forecast & Opportunities, 2020-2030F”, The United States Secondary Water And Wastewater Treatment Equipment Market was valued at USD 19.71 Billion in 2024 and is expected to reach USD 25.00 Billion by 2030 with a CAGR of 3.89% during the forecast period. Membrane bioreactor (MBR) systems are gaining popularity across the U.S. due to their ability to deliver high-quality effluent in a compact footprint. These systems integrate conventional biological treatment processes with membrane filtration, allowing for enhanced removal of contaminants including suspended solids, bacteria, and pathogens. MBRs are especially attractive in densely populated regions and facilities where space is limited, yet the demand for stringent discharge standards is high. Many municipal utilities are upgrading from conventional activated sludge systems to MBRs to comply with stricter wastewater discharge regulations. Additionally, these systems are seen as essential in advanced reuse applications such as indirect potable reuse and industrial recycling. With improvements in membrane durability and reductions in fouling rates, operational efficiency has significantly improved, lowering lifecycle costs. This trend is further supported by rising concerns around water scarcity and the need for more effective wastewater recycling solutions.

Digital transformation is reshaping the wastewater treatment landscape in the U.S., with secondary treatment facilities increasingly integrating automation and smart monitoring systems. Advanced technologies like IoT sensors, SCADA systems, and AI-based analytics enable real-time performance tracking, predictive maintenance, and data-driven decision-making. These capabilities reduce the need for manual oversight and increase operational efficiency. For aging infrastructure and decentralized systems, digital tools offer better reliability and control. Utilities are leveraging automated systems to monitor biological oxygen demand (BOD), total suspended solids (TSS), and other critical parameters continuously, helping meet compliance requirements more easily. The use of remote monitoring reduces manpower requirements, a critical advantage amid labor shortages. Furthermore, digital twins and simulation software allow facilities to test treatment process changes virtually before implementation. This trend is expected to continue as utilities prioritize resilience, operational efficiency, and cost-effectiveness.

Based on Equipment Type, Filtration Equipment is the fastest growing segment in the United States Secondary Water And Wastewater Treatment Equipment market during the forecast period, due to several critical factors. Filtration systems play a pivotal role in removing suspended solids, microorganisms, and other contaminants from wastewater, making them essential for meeting increasingly stringent water quality standards set by federal and state regulatory bodies such as the EPA. The rise in industrial activities and urbanization has led to higher volumes of wastewater requiring effective secondary treatment, pushing demand for advanced filtration solutions.

Technological advancements in filtration, including membrane filtration, microfiltration, and ultrafiltration, have enhanced treatment efficiency and reduced operational costs, encouraging wider adoption. These systems offer benefits like improved water reuse potential and compliance with environmental discharge norms, which are especially crucial in regions facing water scarcity or strict pollution control mandates. Furthermore, increasing investments in upgrading aging wastewater infrastructure in municipalities and industries drive the replacement or retrofitting of conventional systems with modern filtration equipment.

Quantitatively, with over 80% of municipal wastewater in the U.S. requiring secondary treatment involving filtration, the segment captures a significant portion of equipment spending. Industrial sectors such as chemical manufacturing, food processing, and pharmaceuticals also heavily rely on filtration to meet effluent quality requirements, adding to the segment’s growth momentum.

Based on region, West is the fastest growing region in the United States Secondary Water And Wastewater Treatment Equipment Market during the forecast period driven by several key factors. Rapid population growth and urbanization in states such as California, Washington, and Arizona have significantly increased water demand and wastewater generation, prompting expansion and modernization of treatment infrastructure. This growth is fueled by ongoing residential, commercial, and industrial developments, especially in drought-prone areas where water conservation and reuse are priorities.

Environmental regulations in the West are some of the most stringent in the country, pushing municipalities and industries to upgrade their secondary treatment systems to meet higher discharge standards. States like California have adopted aggressive water quality policies and water recycling mandates, creating strong demand for advanced wastewater treatment equipment that can support tertiary and reuse applications, with secondary treatment acting as a critical intermediary step.

Moreover, the Western U.S. faces unique challenges related to water scarcity and climate change, including prolonged droughts and reduced surface water supplies. These conditions drive investments in efficient, reliable secondary treatment technologies that enable water reuse and help mitigate stress on limited freshwater sources. Public and private funding initiatives focused on sustainable water management also boost equipment purchases and infrastructure projects.

The region’s technological innovation ecosystem supports the adoption of advanced secondary treatment solutions, such as membrane bioreactors and enhanced filtration systems, improving treatment efficiency and reducing operational costs. Additionally, many municipalities in the West are replacing aging infrastructure, further accelerating demand for modern secondary water and wastewater treatment equipment.
