Secondary treatment dominates the process segment with nearly 46% share in 2024. This stage removes high organic loads and supports regulatory compliance. Municipal plants depend on secondary systems to meet discharge norms. Biological treatment upgrades rise due to tougher nutrient limits. Tertiary treatment grows as reuse projects expand in drought-prone states. Primary treatment remains essential for solids removal before advanced steps. Federal and state funding for modernization drives adoption of efficient secondary systems.
By Application
Municipal use leads the application segment with around 58% share in 2024. Cities invest heavily in network repair, plant expansion, and reuse programs. Rising population and aging water systems push local bodies to adopt advanced treatment. Industrial demand grows in food, chemicals, and power sectors needing high-quality processed water. Strict discharge rules accelerate industrial recycling systems. Municipal spending remains the core growth driver as utilities adopt modern, energy-efficient solutions.
Key Growth Drivers
Rising Regulatory Pressure on Water Quality
Stricter national and state-level standards drive major upgrades in US water and wastewater systems. Utilities face tighter limits on nutrients, pathogens, PFAS, microplastics, and emerging contaminants. The EPA’s evolving compliance rules push cities to adopt advanced filtration, biological treatment, and high-efficiency disinfection. Municipal operators also invest in modern monitoring tools to reduce violations. Growing public concern about water safety raises pressure on local governments to improve system reliability. Many older treatment plants run beyond design capacity, forcing modernization. Large federal programs, including infrastructure funding, accelerate plant expansion and upgrades. These regulatory shifts keep demand strong across equipment, chemicals, and digital solutions.
For instance, Evoqua Water Technologies has multiple documented projects in Michigan involving granular activated carbon (GAC) and ion-exchange (IX) systems. A notable project in Muskegon, MI, used mobile GAC filtration to treat 21 million gallons (~79 million liters) of water over two months.
Aging Water Infrastructure and High Replacement Needs
Most US treatment plants, pipelines, and pumping stations are several decades old and require urgent renewal. Frequent pipeline failures, leakage, and operational inefficiencies push utilities to invest in rehabilitation and replacement. Aging assets raise maintenance costs and energy use, increasing pressure to shift toward modern, automated systems. Municipalities replace outdated clarifiers, sludge equipment, and disinfection units with compact, efficient technologies. Population growth adds more load on old networks, prompting expansions to meet rising demand. Federal and state financing supports large-scale upgrades in rural and urban regions. This long-term replacement cycle creates steady demand for advanced treatment solutions, engineering services, and performance-enhancing components.
Growing Water Reuse and Resource Recovery Focus
Water-scarce states adopt large reuse programs to reduce dependence on freshwater sources. Wastewater is increasingly seen as a recoverable resource rather than a liability. Municipalities implement tertiary and advanced treatment stages to support irrigation, industrial reuse, and indirect potable reuse. Technologies like membrane separation, reverse osmosis, and UV-advanced oxidation gain strong adoption. Sludge management shifts toward energy recovery and nutrient extraction, offering cost savings for utilities. Industrial users recycle more water to reduce discharge fees and improve sustainability. Federal funding promotes reuse systems in drought-prone regions, boosting demand for related technologies and services.
Key Trends & Opportunities
Expansion of Digital Water Technologies
Utilities adopt smart sensors, real-time monitoring, digital twins, and AI-based predictive tools to improve plant performance. Digital platforms help reduce energy consumption, optimize chemical dosing, and extend equipment life. Remote monitoring supports small and rural utilities with limited technical staff. Predictive analytics lower failure risks and enhance regulatory compliance. Rising cybersecurity solutions also support secure operations. Vendors offering integrated digital and mechanical solutions gain strong growth prospects. As data-driven decision-making expands, digital water technologies open new opportunities for equipment suppliers, software providers, and engineering firms.
For instance, Xylem deployed its digital monitoring and analytics platform at the Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C., which treats roughly 1.4 billion liters of wastewater per day. The system integrates thousands of real-time sensor inputs across aeration, nutrient removal, and pumping operations. The deployment supports predictive maintenance and operational optimization across one of the largest treatment facilities in North America.
Rising Adoption of Advanced Treatment for Emerging Contaminants
PFAS, pharmaceuticals, personal-care chemicals, and microplastics push demand for specialized treatment systems. Utilities adopt granular activated carbon, ion exchange, UV-AOP, and high-pressure membranes to meet evolving limits. States set their own strict PFAS standards, increasing equipment needs across drinking water and wastewater plants. Growth in industrial pretreatment systems also accelerates adoption of advanced solutions. Research funding boosts innovation in low-cost removal technologies, creating new opportunities for suppliers. As public awareness rises, advanced contaminant removal remains a major investment focus.
For instance, The GWRS uses a “three-step” advanced process: microfiltration, reverse osmosis (RO), and advanced oxidation (ultraviolet light with hydrogen peroxide) to purify treated wastewater.
Growth in Decentralized Treatment Systems
Small communities, remote areas, and new developments adopt decentralized systems to avoid high pipeline and plant construction costs. Modular units offer scalability, faster installation, and lower operating cost. Developers use decentralized treatment for housing projects and commercial sites where municipal access is limited. Industrial parks install compact reuse systems to reduce freshwater withdrawals. Growing interest in resilient infrastructure boosts adoption of stand-alone systems that continue operating during power outages or extreme weather. This shift opens opportunities for manufacturers offering containerized, plug-and-play technologies.
Key Challenge
High Capital and Operating Costs
Treatment plants require major investment for construction, modernization, and advanced technologies. Smaller utilities struggle to fund membrane systems, reuse upgrades, digital tools, and PFAS removal equipment. Rising energy and chemical costs increase operational burdens. Many municipalities face budget constraints, delaying essential rehabilitation. Skilled labor shortages raise wages and slow implementation of complex projects. High initial cost limits adoption of advanced systems, especially in smaller communities. Financing gaps remain a major barrier despite federal support. Vendors must offer cost-efficient designs, modular systems, and long-term service packages to overcome these constraints.
Workforce Shortages and Operational Skill Gaps
The US water sector faces a large retiring workforce and a limited pipeline of new operators. Treatment processes require skilled staff to manage biological systems, membrane operations, and digital tools. Utilities struggle to fill operator, maintenance, and instrumentation roles. Limited training budgets make it difficult to adopt advanced technologies. Workforce shortages increase the risk of regulatory violations and plant downtime. Smaller utilities face the biggest challenge due to lower salaries and restricted training programs. Addressing skill gaps through automation, remote support, and operator-training programs remains essential for sustained system reliability.
