Engineered Solutions for Minimal Disruption
WJ Groundwater have considerable experience dewatering basements in business bay, Dubai. The Skyscraper Tower is a great example of where deepwells have been successfully used to control groundwater levels on site. This has allowed the client, Al Arab Contractors and Al Attar Properties, to construct a deep basement next to open water. The site is next to the future path of the Dubai Water Canal and is in a prime real-estate location.
To maintain excavation stability the dig has been shored with a combination of diaphragm walls on two sides including along the canal edge, secant piles on one side and open cut on the remaining side with a battered slope.
To achieve the drawdown in the 25m deep basement internal deepwells fitted with high efficiency electric submersible deepwell pumps are operated from a central control cabin.
WJ were awarded the works as we confidently proved to be a cost effective solution that met the requirements of the client and main contractor for a low maintenance and reliable dewatering solution. Our considerable experience gained dewatering basements, shafts, bridges, tunnels and now the Dubai Water Canal allows us to bring confidence and low cost solutions to future projects along business bay and the Dubai Water Canal.

WJ Offer a Comprehensive Selection of Tools
Design Expertise
As co-authors of CIRIA C750 Groundwater Control: Design and Practice, we take pride in our extensive design capabilities. Our proficiency extends to 2D and 3D computer modeling, ensuring precision and effectiveness in crafting dewatering solutions tailored to your project's unique requirements.
Pumping Tests
Conducting thorough pumping tests allows us to intimately understand site conditions, providing valuable data for cost-effective installations and optimised program timelines. This not only reduces operating costs but also validates the original design, instilling extra confidence in both budgets and project timelines. Our commitment to comprehensive site understanding sets us apart in delivering efficient and reliable solutions.
Our Expert Optimisation Techniques
In the pursuit of optimal dewatering solutions, we implement a spectrum of sophisticated techniques. Empirical optimisation, grounded in extensive experience and industry-established 'rules of thumb,' enables the fine-tuning of dewatering systems. Observational optimisation relies on on-site observations, particularly monitoring drawdown versus flow, providing invaluable insights for troubleshooting when ground conditions deviate from expectations.
Analytical optimisation employs precise analytical equations to estimate essential parameters for system design. Furthermore, numerical optimisation harnesses available data to populate intricate 2D and 3D models, facilitating a comprehensive analysis through a series of refined and simplified techniques. This comprehensive and strategic approach ensures the customisation of solutions tailored to the distinct requirements of each project, reflecting our commitment to professionalism and excellence..
