Automatic Effluent Samplers Market Report 2026

The automatic effluent samplers market size has grown rapidly in recent years. It will grow from $1.83 billion in 2025 to $2.02 billion in 2026 at a compound annual growth rate (CAGR) of 10.7%. The growth in the historic period can be attributed to stricter environmental regulations, expansion of industrial wastewater treatment facilities, increasing monitoring of municipal discharge systems, growth of environmental testing laboratories, adoption of automated sampling technologies.

The automatic effluent samplers market size is expected to see rapid growth in the next few years. It will grow to $3.03 billion in 2030 at a compound annual growth rate (CAGR) of 10.6%. The growth in the forecast period can be attributed to increasing investments in smart water monitoring systems, rising demand for real-time pollution tracking, expansion of environmental compliance enforcement, growing adoption of IoT-enabled samplers, increasing focus on data accuracy and traceability. Major trends in the forecast period include increasing deployment of programmable sampling systems, rising integration of sensor-based monitoring, growing adoption of remote-controlled samplers, expansion of refrigerated composite sampling solutions, enhanced focus on regulatory compliance accuracy.

The increasing prevalence of waterborne diseases is expected to propel the growth of the automatic effluent samplers market going forward. Waterborne diseases are illnesses caused by consuming or coming into contact with contaminated water containing harmful microorganisms such as bacteria, viruses, or parasites. The rise in waterborne diseases is driven by factors such as poor sanitation, inadequate water treatment, and environmental pollution. Automatic effluent samplers improve water quality management by enabling efficient and accurate wastewater sampling. They facilitate timely detection of pollutants, supporting enhanced environmental monitoring and public health protection. For instance, in September 2024, according to the World Health Organization (WHO), a Switzerland-based intergovernmental organization, cholera cases rose by 13% and related deaths surged by 71% in 2023 compared to 2022. Therefore, the increasing prevalence of waterborne diseases is driving the growth of the automatic effluent samplers market.

Major companies in the automatic effluent samplers market are focusing on innovations such as autonomous water samplers to enable continuous, high-precision aquatic monitoring with minimal human involvement. An autonomous water sampler is an automated device that collects, preserves, and stores water samples according to programmed schedules to support environmental assessment and regulatory monitoring. For instance, in March 2025, NatureMetrics, a UK-based nature intelligence company, and Dartmouth Ocean Technologies, a Canada-based oceanographic instrument manufacturer, launched the DOT-NM Autosampler. The system autonomously collects sequential eDNA samples, preserves them onboard, and operates for extended periods without vessel-based sampling efforts. Engineered with configurable sampling routines, depth-rated deployment options, and integration with end-to-end eDNA analytics, the device provides scalable biodiversity insights while substantially lowering operational costs, safety risks, and carbon impact.

In May 2023, Xylem Inc., a US-based water technology company, completed the acquisition of Evoqua Water Technologies LLC for approximately $7.5 billion. This acquisition aims to establish a comprehensive platform to address critical water challenges on a larger scale by integrating Xylem’s innovative solutions with Evoqua’s specialized water treatment capabilities. Evoqua Water Technologies LLC, based in the US, is a clean technology company engaged in the production of automatic effluent samplers.
