The composition of waste water from food processing and other plants varies with time. A composite sample composed of smaller samples taken at different times will represent an average condition of these flows. The sampling system described in this paper will gather subsamples over a 24‐hour or longer period and keep the composite sample frozen until ready for laboratory analysis. This system will work equally well on pressurized pipelines or ponded water. The parts cost per controller is approximately $80.00 plus the price of a freezer, associated plumbing, and a pump if the water sample is not in a pressurized pipeline.
