Abstract: 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.
