A water leakage position estimation system (S) configured to estimate a water leakage position in a pipe network including a plurality of pipe routes includes a water leakage determination unit (11) estimation unit (12e) . The water leakage determination unit (11) determines whether a water leakage occurs in the pipe network based on a measured value of a vibration related to the pipe network that is acquired by a water leakage sensor (2) provided in the pipe network. The estimation unit (12e) estimates, when the water leakage determination unit (11) determines that a water leakage occurs in the pipe network, a pipe route in which the water leakage occurs from the plurality of pipe routes based on the measured value and a predicted value of the vibration for each pipe route acquirable by the water leakage sensor (2) when a water leakage occurs in each pipe route.

A method includes providing a length of pipeline that has a housing defining a central bore extending the length of the pipe and a space formed within the housing and extending the length of the pipe. At least one condition within the space is continuously monitored within the space to detect in real time if a change in the housing occurs.

A system and method of detecting a disturbance of a buried structure, for example an intrusion or a leak from a pipeline. Sensing devices at discrete locations connect with a backbone cable extending along a length of the pipeline. In the event of a leak, the signal from a sensing device is received at an output, via the backbone cable, providing notification of the leak and the location of the leak.

A device and method of pressure testing a conduit structure to determine if there is a leak in a conduit layout, which includes employing a pressure testing device having a first part having a coupling end for sealably connecting to a first conduit portion, a second part communicably connecting to the first part and having a valve connection adapted to receive one of a positive pressure source and a negative pressure source, and a pressure meter operably connected to the pressure testing device, wherein the valve is open to receive one of the positive pressure source and the negative pressure source, the pressure meter displays one of a positive pressure and a negative pressure, opening the valve to receive one of the positive pressure source and negative pressure source, and reading the pressure on the pressure meter to determine if the pressure is being maintained.
