The challenge is simultaneously creating major investment opportunities in membrane bioreactors, smart pumping systems, and digitally automated wastewater treatment infrastructure. Utilities are increasingly replacing conventional activated sludge systems with membrane-based treatment technologies that improve effluent quality and support wastewater reuse applications. For instance, Integrated water services partnered with CROM in 2026 to launch the NXT|MBR™ modular wastewater treatment platform for municipal and water reuse projects, targeting long-life decentralized treatment infrastructure investments . Municipalities are also investing in automated flow-control systems and predictive maintenance platforms to modernize aging wastewater networks.

The opportunity is expanding further through federal infrastructure funding and long-term resilience planning initiatives across North America. For instance, BluMetric Environmental secured a USD 1.5 million contract in 2026 for a membrane bioreactor wastewater treatment plant in Florida, designed for residential wastewater reuse expansion. The project includes scalable treatment capacity for future infrastructure growth .

Calgon Carbon announced a nearly USD 100 million investment in 2026 to expand drinking water and PFAS treatment infrastructure capacity at its Ohio facility ahead of future EPA compliance deadlines. Utilities are increasingly prioritizing decentralized wastewater reuse facilities, advanced sludge treatment systems, and energy-efficient pumping technologies in capital planning strategies. As regulatory compliance requirements tighten, investments in advanced membrane filtration and wastewater transfer infrastructure are expected to increase steadily.

Segmentation Analysis

Municipal Utilities as Centralized Demand Hubs Accelerating Membrane-Based Water and Wastewater Infrastructure Expansion

Municipalities are the leading end-users for membrane-based wastewater treatment with a market share of 43% because wastewater generation is inherently centralized, regulated, and continuously increasing in urban systems, while membranes are one of the few technologies that can reliably meet tightening discharge and reuse standards at scale.

Municipal wastewater streams are highly variable and heavily contaminated, including domestic sewage, stormwater, and small industrial inputs. Therefore, conventional treatment alone often cannot meet modern discharge norms, especially for nutrients (nitrogen, phosphorus), pathogens, and emerging contaminants. Membrane systems (UF/MF/RO) solve this by providing a physical barrier that ensures consistent effluent quality regardless of inflow variability, which is critical for city-scale operations where water quality cannot fluctuate.

Municipal systems manage continuous and high-volume wastewater streams from entire urban populations, requiring consistent treatment reliability and strict compliance with discharge standards under frameworks such as the U.S. EPA Clean Water Act regulations. This makes membrane technologies, especially MBR, UF, and RO, critical for achieving stable effluent quality and meeting tightening nutrient and contaminant limits.

In addition, rising water scarcity and increasing emphasis on water reuse have transformed municipal wastewater from a disposal challenge into a resource recovery opportunity. Projects across major cities are integrating advanced membrane systems to produce reclaimed water for industrial use, irrigation, and potable reuse, further strengthening demand. For instance, the City of San Diego Public Utilities Department is building one of the largest membrane-based wastewater reuse systems in the U.S. It converts treated wastewater into drinking water using membrane filtration and reverse osmosis with UV advanced oxidation , showing how municipalities adopt membranes for potable reuse at scale.

Combined with large-scale government funding and the urgent need to upgrade aging treatment infrastructure, municipalities consistently invest at a higher and more sustained rate than any other end-user segment. This structural dependence on regulation, population-scale demand, and reuse-driven water strategies ensures that municipalities will continue to dominate membrane-based wastewater treatment adoption in North America. By end user type, the market is classified into:

• Municipal
• Pulp and Paper
• Chemical
• Food and Beverage
• Healthcare
• Power
• Other

This project plays a critical role in demonstrating the scalability of membrane-based systems for high-population urban regions, with the plant serving wastewater treatment needs for approximately 1.4 million residents.

Therefore, Polymeric membranes benefit from long-term municipal procurement cycles, infrastructure replacement demand, and increasing reuse initiatives. Ceramic membranes remain limited due to high cost, while thin-film composites and spiral wound configurations are more specialized in RO applications. As the government and industries continue upgrading aging wastewater infrastructure and expanding reuse capacity, polymeric membranes maintain structural dominance due to their economic and operational alignment with large-scale public water systems. By membrane material, the market is further segmented into the following categories:

• Polymeric
• Ceramic
• Thin-film composite
