Global Market Size, Forecast, and Trend Highlights Over 2025-2037
Industrial Wastewater Treatment Market size was valued at approximately USD 18.3 billion in 2024 and is projected to reach USD 40.4 billion by 2037, growing at a CAGR of 6.5% during the forecast period from 2025 to 2037. In 2025, the industry size of industrial wastewater treatment is assessed at USD 19.3 billion.
The industrial wastewater treatment market is largely influenced by strict regulatory frameworks set forth by organizations like the U.S. Environmental Protection Agency (EPA). The EPA's Effluent Guidelines Program, which the Clean Water Act requires, sets national standards for wastewater discharges from approximately 45,000 industrial facilities that directly release effluents into U.S. waters, in addition to another 130,000 facilities that discharge into municipal sewage systems. These regulations, driven by technology, compel industries to implement advanced wastewater treatment solutions to comply with the designated discharge limits. As regulatory demands intensify, industries are increasingly adopting innovative, efficient, and cost-effective treatment technologies, which significantly boost industrial wastewater treatment market demand and stimulate growth across the sector.
The factors related to supply chains and the economy have a profound effect on the field of industrial wastewater treatment. The EPA’s Municipal Wastewater Treatment Plant Operation and Maintenance Cost Index offers critical insights into the comprehensive cost structures involved, which include labor, chemicals, energy, and maintenance costs. At the same time, the Clean Water State Revolving Fund (CWSRF) has been instrumental in providing more than $154 billion in funding to support essential infrastructure initiatives aimed at enhancing wastewater treatment systems nationwide. These economic factors, in conjunction with regulatory mandates, stimulate investments in advanced wastewater treatment technologies. Together, they shape industrial wastewater treatment market dynamics by fostering technological progress and expanding treatment capacity across the United States.
