WJ Groundwater’s Toby Roberts was one of three speakers at a well-attended Groundwater Control In Urban Areas conference organised jointly by the Geological Society Engineering Group and British Geotechnical Association. The event was a part of the celebration of a Year of Water and was focused on dewatering. Toby was one of the experts invited to speak about the groundwater control in cities and its challenges – including increasingly restricted locations and potential impacts arising from the interaction of dewatering and urban environments. The three speakers explored the subject using examples of recent dewatering projects in the London Basin.

Toby gave a presentation concerning dewatering and depressurisation strategies used to target the Lambeth Group Channel Sands for the tunnel works in London.
