Wastewater Treatment Plant Market Size, Value And Growth Trajectory Through 2030
The wastewater treatment plant market has experienced significant growth over the past few years. Projections indicate it will expand from $141.65 billion in 2025 to reach $149 billion by 2026, exhibiting a compound annual growth rate (CAGR) of 5.2%. Historically, this growth can be linked to the development of urban wastewater infrastructure, increased generation of industrial effluent, more stringent environmental discharge rules, the implementation of biological treatment approaches, and the expansion of municipal sewage networks.
The wastewater treatment plant market size is projected to experience robust growth in the upcoming years. It is anticipated to reach $182.19 billion by 2030, demonstrating a compound annual growth rate (CAGR) of 5.2%. This projected expansion during the forecast period is driven by increasing investments in sophisticated wastewater treatment, a rising demand for decentralized treatment solutions, the broadening of water reuse applications, the growing implementation of digital plant management, and an escalating focus on energy-efficient treatment processes. Key developments expected in the forecast period include the wider deployment of advanced treatment technologies, increased adoption of smart monitoring systems, a stronger emphasis on water reuse and recycling, the expansion of membrane and hybrid treatment processes, and an elevated focus on operational efficiency.

Wastewater Treatment Plant Market Growth Catalysts And Demand Drivers
The escalating levels of water pollution are projected to boost the growth of the wastewater treatment plant market. Water pollution arises when detrimental substances contaminate water bodies, rendering them harmful to humans or the environment. Addressing this issue necessitates global collaboration to tackle the growing problem and develop remedies such as enhanced water monitoring and wastewater treatment. Wastewater treatment plants are essential in combating water pollution by managing and processing wastewater to protect water quality and ensure sustainable water management practices. For instance, according to the Environment Agency, a UK-based government department, in August 2025 it was reported that in 2024, the total number of pollution incidents from sewerage and water supply assets increased by 29% compared with 2023, an rise considered unacceptable. Hence, the increasing prevalence of water pollution is a key driver for the expansion of the wastewater treatment plant market.

Wastewater Treatment Plant Market Trends Shaping Long-Term Demand
Leading firms within the wastewater treatment plant market are creating advanced solutions, including high-strength peracetic acid (PAA) antimicrobial control systems, to effectively manage microbial populations. These high-strength PAA antimicrobial control systems represent chemical formulations employing concentrated PAA to quickly disinfect and restrict microbial proliferation across water and wastewater treatment operations. For example, in September 2025, Enviro Tech, a U.S.-based specialty chemical producer and an Arxada subsidiary, introduced Peragreen 26WW. This product is an inventive antimicrobial control solution designed to boost wastewater treatment efficiency and improve operational sustainability. Peragreen 26WW incorporates a biodegradable peracetic acid formula, which swiftly diminishes microbial contaminants, seamlessly integrates into current infrastructure without requiring significant modifications, and helps facilities reduce their overall chemical consumption and maintenance expenditures.
