Abstract
The present invention provides a method and apparatus for wastewater sampling in all climates. The wastewater sampling apparatus pulls a sample from a stream or other body of water based on flow or time maintaining a consistent, repeatable, and accurate sample size. The present invention includes an all-weather housing. An integrated touchscreen control provides the ability to specify the volumes of water and program times and/or flow intervals to collect samples. Controls also allow control of the temperature within the sample compartment, both from the unit directly or from an external device. The present invention includes arcuate sample chamber and pivoting sample tube for accurate wastewater volume samples. The present invention may pull samples with vertical lifts of up to 29 feet or more and provide consistent accurate sampling exceeding current EPA transport velocity.
