1. A method for wastewater sampling comprising:
radially positioning, by a controller, a first end of a sample tube within a sample chamber to receive a wastewater sample volume;
directing, by the controller, a vacuum/pressure pump to initiate a vacuum cycle to pull a vacuum on the sample chamber to draw the wastewater sample into the sample chamber; and
energizing, by the controller, the vacuum/pressure pump to pressurize the sample chamber upon receiving a predetermined oversample volume of the wastewater sample to force the oversample volume from the sample chamber.
