Composite wastewater sampler
Improve sampling accuracy with a composite wastewater sampler
A composite wastewater sampler is designed to collect multiple wastewater samples over a defined period, creating one representative sample for laboratory analysis. Instead of analyzing a single grab sample, composite sampling provides a more accurate reflection of wastewater quality by accounting for fluctuations in flow and pollutant concentrations throughout the day.
TEC42 develops advanced composite wastewater samplers that help industrial companies, municipalities and water authorities perform reliable wastewater monitoring while meeting environmental regulations.

What is a composite wastewater sampler?
A composite wastewater sampler automatically collects small volumes of wastewater at predetermined intervals or based on the flow rate. These individual samples are combined into one composite sample that represents the wastewater over a specific monitoring period. Because wastewater characteristics can change significantly during daily operations, a single sample may not accurately represent the actual discharge, while a composite sample provides much more reliable information. Composite wastewater samplers are suitable for:
- Industrial wastewater monitoring
- Municipal wastewater systems
- Wastewater treatment plants
- Environmental compliance programmes
Benefits of composite sampling
Using a composite wastewater sampler offers several advantages over manual or grab sampling. Composite sampling provides:
- More representative laboratory results
- Improved compliance with environmental regulations
- Reduced influence of short-term fluctuations
Because samples are collected automatically, organizations also benefit from improved consistency and reduced labour. For samples collected over several hours, combine composite sampling with a refrigerated wastewater sampler to preserve sample integrity.
