    • WJ designed and installed an effective solution to control the groundwater for our basement excavation and deep core areas. Their work was carried out efficiently, safely and to programme

      Stuart Jackson Project Manager – RHSC, Brookfield Multiplex, Edinburgh
    • Great, friendly service. Very helpful and easy to work with.

      Guy Bainbridge Quantity Surveyor – Mickleton, M Lambe Construction
    • We engaged WJ Groundwater to drill the new ground source energy well at UCL as they had successfully installed an abstraction well at the same site in 2014. This section of the work required careful planning to align with the main site activities. The WJ team carried out the works on programme and worked well with the main contractor to ensure that this logistically challenging project was delivered successfully.

      Iain Howley Director – University College London, Ground Source Consult Ltd
    • WJ’s installation team was excellent. The dewatering and groundwater recharge system worked as per WJ model & design. The works, including the Groundwater Treatment Plant setup and demobilisation, were carried out according to the programme. We received very good technical support with prompt production of monitoring data & reports.  Of special note was WJ‘s expertise in contractor assistance to mitigate risks for our forward planning.

      UK Project Update – Anchorsholme Outfall Cofferdam

      WJ are once again showing our technical prowess with another challenging project in Anchorsholme; dewatering a cofferdam in the Irish Sea!

      WJ have been working in and around Blackpool for several years now, having completed the Anchorsholme Park Storage Phase 1 and Phase 2 works for Ward and Burke and the Lennox Gate project for Ward and Burke and JN Bentley, both during 2016 and 2017.

      Our latest project, working with the CH2M HILLVolkerStevin joint venture, C2V+, was to aid the construction of a new 6m by 20m cofferdam in the Irish Sea, directly off the coast from the Anchorsholme Park Storage site. The particularly challenging aspect of this project was the offshore location of the cofferdam, fortunately WJ have undertaken several similar projects to this in recent years in Ipswich and Dover.

      The dewatering system comprised eight 9.5m deep deepwells installed around the internal perimeter of the cofferdam, installed using a rotary drilling rig, in to interbedded sand and clay deposits during February 2018.

      The first technical challenge on this project was the installation of the wells themselves. It was only possible to install during the two 6-hr low tide windows each day, as during high tides the cofferdam would be flooded. During each of these windows it was necessary to pump out the cofferdam, crane the drilling rig in to position, drill, seal off the works so they wouldn’t flood when the tide came back in, and remove the rig from the cofferdam. Fortunately due to the meticulous planning of the works by the WJ Project Engineer, Michael Cummiskey, the wells were all successfully installed during the planned installation period.

      The second technical challenge was also a result of the offshore location. As the cofferdam would be flooded during high tides it was necessary for the WJ control cabin and generators to be located onshore on an existing revetment, above the maximum tide level, with cables running between the cofferdam and the cabins along the beach and existing sea defences.

      Despite the best efforts of the Irish Sea the target drawdown was successfully achieved and the pumping is due to continue until the end of April.

      WJ Engineer’s Sporting Success!

      This week WJ are proudly celebrating the success of one of our colleagues away from the field of groundwater management!

      Chris Robson, one of our monitoring engineers based in our UK office, has a long history in football having had a successful playing career before gaining his UEFA B coaching license. Chris is now manager of Totternhoe F.C, who play in the Spartan South Midlands League Division Two and has enjoyed great success since taking over as manager of the club, culminating in their latest triumph, a 2-0 win over Cranfield United in the Bedfordshire FA Senior Trophy!

      The match was held at Bedford Town’s 3,000 seater Eyrie Stadium, and was a closely contested affair with Jack Lauder scoring to give Totternhoe the lead in the 24th minute. Joe Smith scored a second for Totternhoe to give them a 2-0 lead going in to half-time. The second half was just as tight, with Totternhoe managing to see out the game despite a big final push from Cranfield in the last ten minutes.

      Chris told the local Luton News:

      ‘I am over the moon for everyone involved at the club, the committee, the players, the staff, and the number of supporters who travelled to cheer us on. To deliver a trophy for them means the world to me.’

      Totternhoe currently lie fourth in the league, 12 points behind the leaders Park View, but have several games in hand due to the successful cup run, and could still challenge for the title. Everyone at WJ wish Chris and Totternhoe the best of luck for the rest of the season and hope they can add another trophy to their proud 112 year history!

      You can read more about the game on the Luton Today website.

      WJ Invest in new Large Capacity Pumps

      WJ Groundwater have a long and enviable reputation as technical leaders in the dewatering industry, renowned for being able to provide a professional and practical solution to groundwater problems. In order to reinforce this position, and to enhance our reputation as the ‘go to’ company for overpumping, WJ have invested in some new larger capacity pumps to add to our already extensive fleet.

      The new pumps were purchased to aid with another high-profile sewage overpumping project at the Dubai Mall, the largest shopping mall in the world with over 1200 stores! The pumping setup included a mixture of WJ’s fuel efficient 16”, 12” and 6” diesel surface pumps, chosen to cope with both the project requirements and to minimise overall project costs to the client, HLG.

      As is often the case in this industry, the biggest challenge WJ faced during the project was logistical. The site was located with an elevated bridge section on one side, and a live road on the other, with the requirement for several hundred metres of the overpumping system, including a 400mm diameter pipe, to be buried through a live construction site. With WJ’s characteristic careful planning, we were able to liaise with local authorities for road closures and the installation works proved to be a great success!

      The system continues to perform extremely well even with the significant changes in flow between peak and low flow times of the day.

      Dubai General Manager Oliver Vincent noted that the success of this project was a perfect example of why WJ have grown so quickly in this newly developing market:

       “It was clear to us that the market wanted a reliable overpumping contractor that not only rented pumps, but also gave a complete service from design, to installation, to operation and maintenance. Yes, we do offer a rental only service, but often we find that clients don’t want to worry about sewage overflowing at night, so they would much rather give the complete package to WJ and rest easy. As we already had the design expertise, plus the backbone of supervisors, engineers and mechanics required to service the system, it was a natural progression for us. As you can imagine, it is very exciting for us as we get to work with some amazing pieces of equipment, with some very high flows and on some fantastic projects.” 

       

      Call WJ Groundwater today to find out how they can help you with your sewage and water control project. WJ are happy to provide advice at early design and prices at tendering stages.
