Agricultural Wastewater Treatment Market Report 2026

The agricultural wastewater treatment market size has grown strongly in recent years. It will grow from $2.99 billion in 2025 to $3.25 billion in 2026 at a compound annual growth rate (CAGR) of 8.8%. The growth in the historic period can be attributed to rising agricultural intensification, growing water contamination incidents, expansion of livestock farming, early regulatory awareness, increasing surface runoff pollution.

The agricultural wastewater treatment market size is expected to see strong growth in the next few years. It will grow to $4.59 billion in 2030 at a compound annual growth rate (CAGR) of 9%. The growth in the forecast period can be attributed to stricter environmental regulations, rising focus on sustainable farming, increasing groundwater protection initiatives, growing demand for safe irrigation water, expansion of wastewater treatment infrastructure. Major trends in the forecast period include increasing adoption of biological wastewater treatment solutions, rising focus on groundwater and soil protection initiatives, growing need for efficient wastewater reuse in farming, expansion of large-scale livestock and dairy waste management practices, strengthening regulatory enforcement on agricultural pollution control.

The increasing demand for agricultural water is anticipated to drive the growth of the agricultural wastewater treatment market in the coming years. Agricultural water refers to water used for cultivating crops and supporting livestock. Treated wastewater can be utilized by farmers either directly for irrigation or indirectly by recharging aquifers, especially as food production must increase to meet the needs of a growing global population. For example, in October 2024, according to the United States Department of Agriculture (USDA), a US-based federal agency, groundwater extracted from on-farm wells accounted for 54% of the irrigation water used on open-field acres, and in 2023 the average well depth reached 241 feet. As a result, rising agricultural water demand is contributing to the expansion of the agricultural wastewater treatment market.

Leading companies in the agricultural wastewater treatment market are concentrating on developing innovative solutions, such as decentralized wastewater treatment plants for agricultural reuse, to address the growing need for sustainable water management, climate resilience, and efficient irrigation in water-stressed farming areas. Decentralized wastewater treatment plants are modular systems designed to treat wastewater near its source rather than relying on large centralized facilities; their key characteristics include smaller installation footprints, reduced infrastructure requirements, and the ability to convert wastewater into water suitable for irrigation, providing a resilient alternative to conventional centralized sewage systems that often involve extensive pipelines and higher energy consumption. For instance, in November 2025, the United Nations Development Programme (UNDP), a US-based organization, inaugurated the Zibdeen Wastewater Treatment Plant in Eastern Ghouta, Rural Damascus. This model facility can treat more than 4,000 cubic meters of wastewater per day and convert it into safe irrigation water for approximately 50,000 people, supporting sustainable agriculture and environmental conservation. The plant incorporates rehabilitated sewage networks and irrigation canals, improves sludge processing for reuse, and strengthens resilient water resource management and livelihoods in agricultural communities. This strategic initiative not only tackles immediate water scarcity issues but also establishes a benchmark for scaling similar climate-resilient water solutions in agricultural regions affected by climate-related stress.

In May 2023, Xylem Inc., a US-based water technology company, acquired Evoqua Water Technologies Corp. for about $7.5 billion. Through this acquisition, Xylem sought to build a more comprehensive and advanced portfolio of water and wastewater solutions to enhance its market leadership, accelerate growth prospects, and more effectively address critical global water challenges across utility, industrial, and commercial end markets. Evoqua Water Technologies Corp. is a US-based provider of water treatment solutions and services, specializing in advanced water and wastewater treatment products, services, and digitally enabled mission-critical systems for industrial, municipal, and commercial customers.
