The method additionally includes evacuating at least some of any gas within the receiving structure through at least one gas outlet opening to create a vacuum within the receiving structure. The method further includes receiving a flow of at least one liquid through at least one fluid inlet opening of the receiving structure, and into the receiving structure. The method further includes discharging at least a portion of the liquid from the receiving structure through at least one liquid outlet opening of the receiving structure.
