Pumping tests are a vital tool in the design and implementation of robust dewatering systems. These tests also act as a key aspect of any groundwater investigation, ground source energy project or water supply well borehole construction.read more
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.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.”

WJ Groundwater are pleased to announce that one of our recent projects in Scotland has been announced as the winner of a prestigious industry prize. WJ were awarded the contract to undertake dewatering works at the site on the outskirts of Glasgow between July 2015 and July 2016, and helped to contribute to the project which was recently awarded ‘UK Project with a Geotechnical Value up to £1.0m by Ground Engineering magazine.
Spring has been another busy period for WJ Groundwater with new contract awards in every corner of the UK, with projects starting in Dover, Port Talbot, Houston in Ayrshire, the Isle of Skye and Woodsmith Mine in North Yorkshire.
WJ Groundwater are pleased to announce the successful commissioning and switch on of their latest project in Blackpool, northern England. This project follows on from other recent projects in the local area, including the Phase 1 works at Anchorsholme in 2016 and at Lennox Gate in 2017.
WJ Groundwater is pleased to announce its latest dewatering project in Blackpool – once the home of the tallest roller-coaster and one of the most recognizable buildings in the UK, the Blackpool Tower.
This project is based at Blackpool South and has been devised in order to improve the quality of the local bathing water and for flood protection. The capacity of the local sewer network is to be increased, and this includes updating one of the town’s pumping stations – Lennox Gate. and construction of a new storage tank at Fishers Field.
WJ Groundwater has been hard at work on a dewatering project for client, the McLaren Group at Bromley, Kent’s new state of the art shopping centre. Known as Bromley South Central and due for completion in late 2017, the project is being overseen and managed by Dr Mark Pickett.
