A vacuum sewage system includes a sump pit for receiving sewage, a valve pit, a valve, a sensor-controller, a first sensor pipe, a sump breather and a second sensor pipe. The sensor-controller activates the valve so as to discharge sewage from the sump pit. The first sensor pipe communicates pressure to the sensor-controller as the level of sewage rises within the sump pit. The second sensor pipe communicates pressure to the sump breather to move the sump breather from a first state to a second state to prevent sewage from entering the sensor-controller and valve. Alternatively, the system may be provided with a single sensor pipe that communicates pressure to both the sensor-controller and to the sump breather.

A controller for a vacuum sewage system includes a housing having multiple chambers. Certain chambers are maintained under atmospheric pressure or vacuum prior to activation of the controller. Ports, valves, orifices and air flow paths located in the housing control the rate of air flow between groups of the chambers during activation of the controller.

A pipe coupling that clamps onto an area adjacent the ends of abutting pipes. The pipe coupling includes first and second clamp members, and a fastener. The first clamp member is hinged to the second clamp member. Both the first and second clamp members are configured to pivotally wrap around a pipe. Each of the first and second clamp members also includes an arched hub portion configured such that when each of the clamp members engages each other the arched hub portions form an arcuate hub. The fastener is configured to couple the arched hub portions together thereby preventing the clamp members from opening.
