Whilst WJ are well known and respected as one of the leading dewatering contractors in the UK, we have many other services within our oeuvre. We recently demonstrated one of these whilst undertaking in-tunnel probe drilling as part of the Thames Tideway works at the Dormay Street Shaft in Wandsworth, South London.read more
On the 17th and 18th of September 2018, the British Geotechnical Association and Engineering Group of the Geological Society hosted the first major conference on Chalk in almost 30 years, right on WJ’s doorstep, at Imperial College in Central London.read more
Back in May WJ UK had the honour of being included in articles in the British National Press because of our work on the Thames Tideway project. This time we’ve gone one step better and can now claim to be ‘as featured on TV’!
Throughout July the BBC have been running a weekly 3-part documentary series entitled ‘The Five Billion Pound Super Sewer’, covering the planning and construction of the new Thames Tideway Super Sewer that is being constructed beneath Central London. WJ have been engaged to undertake pumping tests and dewatering on a number of sites across the West, Central and Eastsections of the project. Many of these sites have been featured on the documentary series, including Beckton Sewage Treatment Works, Abbey Mills and Chambers Wharf.
The third and final episode in the series included the construction of the Kirtling Street Shaft in Batterseawhich, because of our experience and expertise in dewatering on large scale infrastructure projects and in this area of London, WJhave been involved with for a number of years.
Due to the importance of dewatering at this site in order to construct the shaft and TBM portals, part of the episode was dedicated to not only dewatering, but we were honoured to have a number of our staff feature prominently in that section of the episode – A rare honour indeed!
And if you haven’t already seen the episode (or want to watch it again!), then the episode is still available to watch on the BBC iPlayer facility here.read more
WJ have been an established part of the dewatering game in the Middle East for over 15 years now since providing the dewatering for the Dubai International Airport Terminal 3development back in 2003, with offices in Dubai since 2005 and our Qatar office due to celebrate its tenth anniversary in 2019. January this year marked our expansion in to nearby Kuwait when we were appointed by the Main Contractor HDEC (Hyundai Engineering and Construction) working under the Client KIPIC (Kuwait Integrated Petroleum Industries Company) for the Al Zour Liquefied Natural Gas (LNG) Terminal Project.
The new terminal is located in the Al-Zour region of Kuwait near to the border with Saudi Arabia, approximately 90km south of the capital Kuwait City, and will include eight LNG storage tanks, each with a capacity of 225,000m3, and associated marine facilities.
Although the sandy ground conditions were prime dewatering territory, the project had the potential to be particularly challenging. Not only would WJ be working in a new country which always brings with it a steep learning curve, but the structures to be dewatered were far from insubstantial – the intake and outfall structures which our systems were going to target were approximately 500m by 200m in size, and up to 15m deep, and the works would be taking place on land reclaimed from the Arabian Gulf. Fortunately there are few things WJ love more than a challenge!
In order to complete the works in a swift and prompt fashion WJ utilised one of our trusted partners, Trevi, to work alongside our own SM14 drilling rig. In total 62 dewatering wells and 10 groundwater monitoring standpipes were installed for the intake structure, and another 21 for the outfall structure. The initial plans were to install both perimeter and internal dewatering systems to draw the groundwater level down to enable a dry excavation, however the perimeter system proved to be so successful that there was no need for the internal system to be installed.
Although the works began at the start of 2018 when the temperatures in Kuwait are relatively comfortable, as the project has progressed the day time working temperatures approached the 40⁰C’s and as the Muslim holy month of Ramadan arrived it became necessary for some of the installation works to be undertaken during the night, with only monitoring to be undertaken during daylight hours. This however had no impact upon the expert level of service WJ are known for.
Hopefully this is the start of long and successful times for WJ in Kuwait and helps to strengthen our position as one of the go-to contractors for any technically challenging dewatering project across the Middle East.read more
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.
WJ Groundwater have been celebrating once again following receipt of our ISO 9001:2015 Quality Management Systems certification, to add to our existing ISO 14001 and 18001 certificates.
The ISO 9001:2015 certification, awarded to WJ by Bureau Veritas, demonstrates the quality management systems and processes that have been put in place in our Dubai, Abu Dhabi and Qatar offices, and is a welcome reward for the hard work of all of our employees.
To celebrate this achievement, a BBQ was held in Dubai and attended by many of the WJ workforce and their families, including Managing Director Richard Fielden, who had flown over from WJ’s UK head office to join in the celebration. It was a highly enjoyable event, with music, drinks, and food, the highlight of which was definitely the Filipino-Style BBQ Chicken Abodo!
This certification keeps WJ’s Middle Eastern branches in line with the consistently high standards set by the Head Office in the UK.
