Abstract
The present disclosure is directed generally to waste water vessels with multiple valved chambers, and associated systems and methods. A method in accordance with a particular embodiment includes drawing waste water into a first chamber under vacuum while the first chamber and a second chamber have at least approximately the same internal pressure. The method further includes allowing the waste water to pass from the first chamber to the second chamber while the first chamber and a second chamber have at least approximately the same internal pressure, releasably sealing the first chamber from fluid communication with the second chamber, and simultaneously adding waste water to the first chamber and removing wastewater from the second chamber while the first chamber is sealed from fluid communication with the second chamber.
