Hanchurch Reservoir, UK
The Hanchurch Service Reservoir stores food-grade water for human consumption and is made of precast concrete walls. It therefore has many wall joints that present a bacteriological risk in the long term, especially because the backfill is placed on the outer walls of the reservoir.
Details of the Fibre Optic Monitoring System
The leakage detection is based on two methods: the Gradient Method and the Heat-Pulse-Method.
