The wastewater treatment plant market has seen considerable growth due to a variety of factors.
• The market size for the wastewater treatment plant has seen considerable growth in the past few years. It's projected to surge from $134.46 billion in 2024 up to $143.61 billion in 2025, with a compound annual growth rate (CAGR) of 6.8%.
This upsurge in the historical term is due to increased investments in water infrastructure, amplified industrialization and expanding industries, population growth and swift urbanization, the enactment of strict environmental laws, and a global rise in water and sanitation Public-Private Partnerships (PPPs).
The wastewater treatment plant market is expected to maintain its strong growth trajectory in upcoming years.
• The market size of the wastewater treatment plant sector is projected to experience significant expansion in the immediate future, growing to a staggering $178.38 billion in 2029 at a compound annual growth rate (CAGR) of 5.6%.
The adoption of stringent regulations about industrial emissions, escalating levels of water pollution, the population surge and urbanization leading to an increased need for clean water, strict governmental rules on wastewater discharge, and heightened awareness around water conservation and recycling can all be seen as drivers of growth for this forecast period. Notable trends for this period include technological advancements, the utilization of decentralized and modular wastewater treatment systems, an increased focus on water reuse and recycling initiatives, the production of biogas in wastewater treatment plants, alongside wastewater treatment 4.0.
The growth of the wastewater treatment plant market is predicted to be fueled by escalating water pollution levels. The contamination of water bodies with detrimental substances makes them toxic to both humans and the environment. The global community needs to join forces to address this escalating problem of water pollution effectively, which can involve methods like enhanced water monitoring and wastewater treatment. Wastewater treatment plants are crucial in tackling water pollution as they help manage and treat wastewater, promoting the protection of water quality and sustainable water management practices. As per the 2022 data of the United Nations, a US-based intergovernmental organization, 2.2 billion individuals still didn't have access to reliably controlled drinking water services, and there was a lack of safely managed sanitation services for 3.5 billion people, demonstrating a surge from the prior year. Thus, the rising water pollution levels are promoting the expansion of the wastewater treatment plant market.

Leading players in the wastewater treatment plant market are concentrating on the deployment of progressive and innovative solutions, such as the Membrane Bioreactor (MBR) wastewater treatment plants, as a strategy to boost their market earnings. MBR wastewater treatment plants represent advanced technology combining a membrane filtration unit with a suspended growth bioreactor like an activated sludge process. For instance, in September 2022, Evac Oy, a Finnish company specializing in integrated waste, wastewater, and freshwater management systems, unveiled a new medium-sized model of its Evac Membrane Bioreactor (MBR) wastewater treatment plant designed for different vessel types. The ground-breaking Evac MBR Mid-range not only meets but also surpasses existing wastewater treatment regulations, offering optimal treatment results by filtering up to 99% of microplastic particles and facilitating nutrient removal. The resultant effluent quality is so excellent that the treated water can be recycled or subject to further processing onboard the vessel. Evac MBR is a critical element of a state-of-the-art wastewater treatment system and is among Evac's main sustainability products. Having a nutrient removal unit within the system allows vessels to function in ecologically delicate areas, offering clean and safe discharge of all wastewater from passengers and crew without posing risks to human health or marine ecology.
