Located below the hustle and bustle of the streets of Bristol this detention tank was built in the late 80’s/early 90’s to cope with any sudden surge in the City’s sewerage system. This underground cathedral is the equivalent to 4 full size football pitches. For most of the time it merely contains a trickle of water but is always ready to fill up at a moments notice. Part of a comprehensive set of drainage and sewage works carried out around the same time it plays an important part in keeping Bristol from flooding – the last serious level of flooding came in the 1960’s and spurred on these projects to ensure the same events don’t happen again.
