A system collects fluid waste within a closed waste vessel where a waste disposal cycle is determined based upon the pressure level within the waste vessel. In the preferred embodiment, a closed liquid waste vessel accepts waste solutions through conduits having valves controlling conduit fluid communication with treatment vessels. A pressure sensor determines the level of pressure within the waste vessel. A pressurizing device reduces the level of pressure within the vessel. When the pressure within the vessel is lowered to a predetermined level, the valve is opened. When the pressure sensed within the liquid waste vessel then rises above an appointed value, the valve is closed, completing the waste collection of a treated sample. This corresponds to the point in time when the treatment vessel is empty, allowing a sudden rush of air into the waste vessel, raising the vessel pressure to ambient and closing the valve. When the pressure in the waste vessel does not rise to the appointed value after the lapse of a preset length of time, a warning signal is provided advising that the system is not working properly.
