A vacuum sewage system includes a collection station, a vacuum pump, a sewage pump, a collection tank, a control system, a valve pit, a first conduit extending from the collection station to the valve pit, a second conduit extending from the valve pit and terminating in a closed end, a valve located in the valve pit for selectively permitting sewage and waste water to flow from the valve pit toward the collection station upon activation of the valve, an electric air admission controller or a solenoid for selectively opening and closing the valve, a first sensor associated with the electronic air admission controller or the solenoid and a second sensor located adjacent the closed end of the second conduit. The system may be utilized to monitor and remedy various undesirable operating conditions in the system and to perform routines to increase operating efficiency of the system.

Method for controlling a vacuum sewage system for a building or for a marine vessel, which includes a vacuum unit (11), vacuum piping (7), a source of sewage (91, 92, 93, 94), and a discharge valve (8) between each source of sewage and the vacuum piping, wherein the vacuum unit generates a predetermined vacuum level in the vacuum piping, in which method the operation of the vacuum sewage system is monitored. In order to ensure an efficiently operating vacuum sewage system, the running time of the vacuum unit is monitored and the vacuum level of the vacuum piping is monitored.

The method of the managed sewer is a Netcentric distributed process that is managed in real-time and implemented through several apparatuses that enable the low capital cost and low installation cost of a smaller diameter pipe (smaller than typically used in gravity flow systems). The apparatuses enable the method of managing the grinding, pumping and staging processes to optimize the effectiveness of the collection process through the small pipe and increase system efficacy by using the pumping and transport action of the material in the pipe as part of the process activity.

A wastewater sewage system is disclosed. The sewage system includes a flow control valve that controls the flow of wastewater through the sewage system such that the sewage pipes in the sewage system are substantially full.

A water diversion system for a job site in a streambed comprises a cofferdam in the streambed upstream of the job site, at least one, preferably two sections of substantially rigid pipe embedded in the cofferdam, a valve or plug in each pipe section to open or close water flow through the pipe, and at least one, preferably two flexible tubes connected to the downstream ends of the pipe sections, respectively. The flexible tubes are configured to lie on the natural streambed and traverse the job site, substantially without grading or otherwise disturbing the natural streambed. An optional positioning and pull straps can be installed on the flexible tubes to assist with moving the tubes and securing the tube in place under water flows. Water diversion paths around and through the job site can alternated or changed by flipping the valves and/or moving the flexible tubes.

Embodiments relate generally to a pump control system for a pressure sewer installation. The system comprises a controller arranged to control supply of power to a pump of the pressure sewer installation. The controller is arranged to receive an output signal from a sensor in a fluid reservoir of the pressure sewer installation, the output signal being indicative of a measured fluid level in the fluid reservoir. A memory is accessible to the controller and is arranged to store operation information pertaining to operation of the pressure sewer installation. A wireless transceiver is in communication with the controller to allow the controller to communicate with a remote server over a communications network.

Embodiments of the present disclosure generally provide a grey water interface valve liquid level sensor system. The liquid level sensor system may deliver information about the water level and the water movement that occurs in a water reservoir. A control unit may then activate a valve to open so that the water can be removed via vacuum.

An extraction valve and vacuum liquid collection system including the extraction valve. The extraction valve includes a valve body having an inlet port defining an inlet passageway, an outlet port defining an outlet passageway, and portions defining a valve seat generally located between the inlet port and the outlet port. A bonnet is mounted to the valve body and cooperates with the valve body to define a fluid chamber communicating the inlet port with the outlet port. The bonnet includes a valve member disposed within the fluid chamber and moveable between engaged and disengaged position with the valve seat. In the engaged position, the valve member prevents fluid communication between the inlet port and the outlet port. Also provided in the valve body is an induction port coupled to a source of ambient or greater pressure air and defining a passageway in fluid communication with the fluid chamber.
