LONDON, GREATER LONDON, UNITED KINGDOM, September 18, 2025 /EINPresswire.com/ -- What Is The Estimated Industry Size Of Wastewater Treatment Plant Market?
In the recent past, the wastewater treatment plant market has witnessed solid growth. The market size, which stands at $134.46 billion in 2024, is projected to expand to $141.65 billion in 2025, delivering a Compound Annual Growth Rate (CAGR) of 5.3%. The significant growth observed in the historical period can be traced back to several factors such as increased investment in water infrastructure, booming industrialization and industry expansion, population growth and swift urbanization, the enforcement of strict environmental laws, and a worldwide surge in Public-Private Partnerships (PPPs) for water and sanitation.

In the upcoming years, the market size for wastewater treatment plants is projected to experience robust growth, expanding to a whopping $173.31 billion by 2029 at a compound annual growth rate (CAGR) of 5.2%. This growth during the forecasted period is largely due to rising levels of water pollution, stringent controls on industrial emissions, a booming population and urban development leading to increased need for purified water, rigorous governmental rules on wastewater emissions, and a growing consciousness about water preservation and reutilization requirements. The forecast period will also witness key trends such as progressive technological developments, adoption of decentralized and modular systems for wastewater treatment, extended initiatives for water recycling and reuse, biogas production in wastewater treatment plants, and the rise of wastewater treatment 4.0.

What Are The Major Trends That Will Shape The Wastewater Treatment Plant Market In The Future?
Key players in the wastewater treatment plant market, like Evac Oy, are implementing new strategies such as the introduction of innovative solutions like the Membrane Bioreactor (MBR) wastewater treatment plants. These innovative MBR systems combine membrane filtration and activated sludge process to treat wastewater effectively. In September 2022, Evac Oy, hailing from Finland and specializing in a suite of management systems for waste, wastewater, and freshwater, took a major step forward by introducing a medium-sized version of their Evac MBR wastewater treatment plant. This plant, designed to serve a range of vessels, not only meets but also exceeds the current wastewater treatment standards. The updated MBR Mid-range by Evac can purify up to 99% of microplastic particles and enables nutrient removal. The superior effluent quality allows the treated water to be reused or processed further while onboard. Among Evac's array of sustainability flagship products, the Evac MBR plays a crucial role for their innovative wastewater treatment system. The inclusion of a nutrient removal unit allows the vessels to function in delicate environments, effectively processing all wastewater from passengers and crew without causing harm to human health or the marine ecosystem.
