Tertiary Water And Wastewater Treatment Equipment Market To Reach $48.6 Billion By 2033

Tertiary Water And Wastewater Treatment Equipment Market Growth & Trends

The global tertiary water and wastewater treatment equipment market size is anticipated to reach USD 48.6 billion by 2033, growing at a CAGR of 5.6% from 2026 to 2033, according to a new report by Grand View Research, Inc. The market growth is driven by factors such as rising urbanization, rapid population growth, the rising need for clean water resources, and the increasing frequency of waterborne diseases. Furthermore, the growing demand for energy-efficient and advanced technologies is anticipated to propel the market growth over the forecast period.

Tertiary treatment is used as the final cleaning step for water before it is reused, recycled, or discharged into the environment. The residual inorganic compounds and pollutants, bacteria, viruses, and parasites are eliminated during this procedure, making the water suitable for reuse.The market is expected to benefit from increasing demand for activated carbon for eliminating residual hazardous compounds in wastewater. These factors are expected to propel the growth of the industry in the coming years. For instance, in November 2020, Koch Separation Solutions acquired RELCO, which offers cutting-edge process technologies for the dairy and food & beverage industries. This strategy was intended to expand the company’s scope of capabilities in the dairy and food & beverage industries.

Furthermore, the Brihanmumbai Municipal Corporation invited tenders for its advanced tertiary treatment plant project in September 2022, with the goal of recycling and reusing effluent water for potable uses. Photocatalytic degradation methods have been extensively used in recent years to eliminate organic contaminants in wastewater and effluents. As a developing destruction technique, advanced oxidation processes (AOPs) have been developed, resulting in the complete mineralization of the majority of organic pollutants. These factors are expected to drive the demand for tertiary water & wastewater treatment equipment.

Moreover, stringent government regulations such as the U.S. EPA and Clean Water Act related to wastewater emission, coupled with the launch of innovative tertiary clarifiers, are expected to drive the demand. For the primary, secondary, or tertiary clarity processes, turbidity removal, softening, or thickening applications, Ovivo offers dependable and robust mechanisms, such as the bioreactor-clarifier, to assure optimal performance. The biochemical oxidation of organic molecules in a contact-weighted load can be intensified using bioreactors-clarifiers for tertiary treatment of urban wastewater using dissolved technical oxygen. This results in the increased efficacy of wastewater treatment by BOD and other components.

In addition, the launch of innovative tertiary water & wastewater treatment equipment, such as chlorinator systems to reduce water-related diseases, is expected to augment the growth of the market. With direct cylinder installation, gas pressure is rapidly reduced to a vacuum through the placement of the vacuum control valve at the source. All installations can benefit from its adaptability due to its capacity to handle all water treatment gases and its adaptable mounting options for manifolds, cylinders, or tone containers.

Tertiary Water And Wastewater Treatment Equipment Market Report Highlights

• Based on region, the Asia Pacific region led the market with the largest global revenue share of 35.7% in 2025. The urban population growth and rising disposable incomes in the region are expected to promote the housing sector growth on a domestic level. Therefore, improving the housing sector is expected to increase the penetration of municipal wastewater facilities, which, in turn, is likely to promote the demand over the forecast period.

• In terms of application, the municipal segment led the market with the largest revenue share of 65.1% in 2025. Several governmental initiatives, such as the National Mission for Clean Ganga, Community Drinking Water Schemes, Jal Jeevan Mission, and Atal Mission for Rejuvenation and Urban Transformation, led to the market growth.

• Based on application, the industrial segment is anticipated to grow at the largest CAGR of 6.0% from 2026 to 2033. Rapid urbanization, technological advancements, and a rising number of production units are resulting in high demand for fresh and processed water. These factors are, in turn, projected to promote the growth of the industry over the forecast period.

• In terms of equipment, the filter segment dominated the market with the largest revenue share of 35.1% in 2025. The total suspended particles, biological oxygen demand (BOD), nitrogen, and phosphorus in the final effluent are all reduced with tertiary filtering. In addition, filters primarily aid in the elimination of leftover suspended materials from wastewater.

• In May 2025, Veolia acquired CDPQ’s 30% stake in its Water Technologies and Solutions subsidiary, gaining full ownership. The acquisition supports Veolia’s strategy to strengthen its presence in water technology, particularly in the United States, and address growing demand for advanced water treatment solutions.
