Early leak detection in wastewater pipelines using fibre Bragg grating sensors
We report on improvements in the design and data processing of a ruggedised, highly sensitive fibre-optic pressure sensor for use in pumped sewer mains. Leak detection and localisation tests were carried out on a plant scale test rig using mains water for a range of leak sizes. The leak-induced pressure drop resolution achieved is better than 100Pa (1mbar) which corresponds to a leak size of approximately 2mm (in a pipe of 100mm in diameter and a flow rate of 16 litres per second).
