Abstract

An example apparatus is for use in a system that includes a sewage pit, a suction pipe in the sewage pit, and a valve between the suction pipe and a vacuum pipe that connects to a sewer system. The apparatus includes a controller configured to perform operations that include: detecting a vacuum pressure in the vacuum pipe, determining that the vacuum pressure in the vacuum pipe is below a predefined pressure, and preventing the valve from opening in response to determining that the vacuum pressure in the vacuum pipe is below the predefined pressure.
