Event type:
Evening meeting
Organised by:

The Geological Society, Burlington House
Event status:

Underground infrastructure developments in urban areas often require control of groundwater in increasingly restricted locations resulting in innovative solutions. The three speakers explore this theme using recent dewatering projects in the London Basin.

Martin Preene begins by summarising the issues involved and the potential impacts arising from the interaction of dewatering and urban environments.

Toby Roberts will focus on dewatering and depressurisation strategies used to target the Lambeth Group channel sands for tunnel works in London.

Emilio Linde-Arias describes a recent project from the east end of London. In order to construct two shafts, one permanent and one temporary, dewatering of the Lambeth Group and the Deep Aquifer was required both from the surface and from within the shafts.


Tea & coffee from 5.30pm

Meeting starts from 6.00pm
