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.

The system of claim 1, wherein the controller is configured to control and monitor operation of the pressure sewer installation and to send stored operation information to the remote server. 3. The system of claim 2, wherein the operation information includes measured fluid level information. 4. The system of claim 1, wherein the controller is configured to compare the fluid level to a fluid level threshold stored in the memory of the controller and to cause the pump to operate to pump fluid out of the fluid reservoir when the fluid level is greater than or equal to the fluid level threshold. 5. The system of claim 1, wherein the wireless transceiver is configured to communicate with the remote server using a mobile telephony standard protocol. 6. The system of claim 1, wherein the system is mains powered and comprises a backup power supply to power the controller and the wireless transceiver in the absence of adequate mains power. 7. The system of claim 1, wherein the controller is further configured to receive a float switch output signal from a float switch in the fluid reservoir indicative of a high fluid level, the controller being configured to operate the pump in response to the float switch output signal. 8. The system of claim 1, wherein the system further comprises one or more additional devices and one or more additional wireless or wired transceivers or receivers in communication with the controller, to allow the controller to communicate with or receive information from the one or more additional devices. 9. The system of claim 8, wherein the one or more additional devices include at least one flow meter or other instrument for monitoring part of a sewerage or water network. 10. The system of claim 1, wherein the pump control system transmits the measured fluid level to the remote server, and the fluid level threshold is determined by the remote server at least in part based on historical data, wherein the historical data comprises past measured fluid levels of the fluid reservoir. 11. A pressure sewer network monitoring system, comprising: a remote server; anda plurality of pump control systems, each pump control system comprising: a controller arranged to control supply of power to a pump of a pressure sewer installation, wherein the controller is arranged to receive an output signal from a sensor in a pressure sewer tank of the pressure sewer installation, the output signal being indicative of a measured fluid level in the pressure sewer tank, and wherein the controller is not configured to determine a fluid level threshold;a memory accessible to the controller and arranged to store operation information pertaining to operation of the pressure sewer installation; anda wireless transceiver in communication with the controller to allow the controller to communicate with the remote server over a communications network;wherein the remote server is in communication with the wireless transceiver of each of the pump control systems;wherein the remote server is configured to monitor operation of each pressure sewer installation based on messages received from each pump control system, to determine a changed fluid level threshold, and to affect operation of each pump control system by transmission of one or more commands from the remote server to each pump control system;wherein the commands comprise instructions to replace a fluid level threshold stored in the memory with the changed fluid level threshold, and wherein the instructions comprise the changed fluid level threshold. 12. The system of claim 11, further comprising a computerised user interface in communication with the remote server to allow remote user control of each pump control system. 13. The system of claim 11, wherein the remote server is configured to determine an alarm condition based on the messages received and to automatically transmit one or more alarm messages to one or more user recipients, the one or more alarm messages including an indication of the alarm condition. 14. The system of claim 11, wherein the remote server is operable to track and store historical data from the plurality of pump control systems, the historical data comprising measured fluid level in each pressure sewer tank, and wherein the fluid level threshold determined by the remote server for each pump control system is determined based at least in part on the historical data. 15. The system of claim 11, wherein the remote server receives at least a first measured fluid level from a first pump control system, and the remote server affects the operation of a second pump control system by determining the changed fluid threshold sent to second pump control system based at least in part on the first measured fluid level. 16. A pressure sewer installation, comprising: a pump control system comprising: a controller arranged to control supply of power to a pump of the pressure sewer installation, wherein the controller is arranged to receive an output signal from a sensor in a pressure sewer tank of the pressure sewer installation, the output signal being indicative of a measured fluid level in the pressure sewer tank, and wherein the controller is not configured to determine a fluid level threshold;a memory accessible to the controller and arranged to store operation information pertaining to operation of the pressure sewer installation; anda wireless transceiver in communication with the controller to allow the controller to communicate with a remote server over a communications network;wherein the controller is configured to be controllable remotely by commands received from the remote server and wherein the controller is responsive to a command received from the remote server to replace the fluid level threshold stored in the memory with a changed fluid level, the fluid level threshold determined by the remote server and not pre-determined at the pump of the pressure sewer installation, wherein the command comprises the changed fluid level threshold; andwherein the pressure sewer installation further comprises the pump, the sensor and the pressure sewer tank. 17.
