Examples of a leak detection system are disclosed. In one example according to aspects of the present disclosure, a leak detection system includes a housing defining an interior, the housing connected to a component of a water distribution system. The leak detection system also includes a leak detection sensor contained within the interior of the housing and configured to detect a leak within the water distribution system. Additionally, the leak detection system includes a digital signal processing circuit in communication with the leak detection sensor.

Hydrant mounting bracket

A mounting bracket for a hydrant that is fully concealed by the hydrant head. The mounting bracket is fastened to the structure and includes tabs which engage the hydrant head to tightly secure the hydrant to the structure. The hydrant head includes a structure engaging periphery such that the mounting screws are fully concealed and protected from the environment.

INTELLIGENT STANDPIPE

A standpipe (15) for drawing water from a mains water supply. The standpipe includes an inlet 9 having a first coupling (7) configured to enable the standpipe to be connected to a hydrant outlet of the mains water supply and an outlet (5) having a second coupling (23) configured to enable a water delivery hose to be connected to the standpipe. A flow meter (3) measures a volume of water flowing from the inlet to the outlet and a data logger (19) is connected to the flow meter and records the volume of water measured. A global positioning system (GPS) module determines the location of the standpipe (15) when the flow meter 3 detects the water flow and a wireless communication module transmits the recorded volume of water and corresponding GPS location to a central monitoring facility (27).
