WJ Groundwater is thrilled to announce that it’s a nominated finalist at this year’s Ground Engineering Awards, The Hilton Park Lane, London on the 30th of June. We have been nominated in the Product and Equipment Innvovation category for in-tunnel drilling, dewatering, depressurisation and probing implementation on the London Crossrail project.
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.
WJ Groundwater recently attended the well supported annual NCE Tunnelling & Underground Space Awards. The event took place on the 3rd of December at the Grosvenor House Hotel, London.
WJ was nominated for an award alongside BBMV JV Crossrail C510 in the Ground Investigation and Monitoring award category for the sub-surface dewatering for a steeply inclined SCL tunnel. Unfortunately, WJ didn’t win this year but our client BBMV were worthy winners in a number of other categories.

Dr Toby Roberts, the Chairman of WJ, gave a fascinating presentation on dewatering cross passages using in-tunnel well systems. The presentation was one of the features at the 3rd Arabian Tunnelling Conference & Exhibition 2015 held in Dubai, UAE in November.
WJ Groundwater is very pleased to share the news that it won the Innovation in Drillingcategory award at the BDA (British Drilling Association) Dinner and Dance 2015 in Edinburgh. The award was for our adapted Baby Giraffa, modified to work in deep excavations and tunnels.
The adapted Baby Giraffa is a fully articulated rotary drilling rig that complements WJ’s existing fleet with its ability to drill at a full range of angles including upwards and horizontally at heights of up to 7m above tunnel ground level. This makes it ideal for probe and depressurisation drilling within tunnels, shafts and basements. As with WJ’s existing SM5 rigs, the Baby Giraffa is operated by remote control allowing it to work in confined spaces where access can be challenging. The drilling rig has already been put to good use drilling probes and wells within tunnels and cross passages on the huge Crossrail project and on WJ projects all around the world.
