When designing dewatering systems, think backwards

An often overlooked aspect in dewatering system design is the safe shutdown and sealing at the end of a project. WJ adopts a unique approach, considering the project’s end before the beginning. Ultimately, the success of a basement project hinges on its dryness, aligning with its intended use, making the thoughtful conclusion of the dewatering system a pivotal factor in our methodology.

The level of allowed dampness varies based on the designated use of a space – a pump room may tolerate some, a car park less, while residential living or a library requires absolute dryness. When planning your dewatering, shoring, and waterproofing system, prioritise the client’s desired outcome. WJ frequently collaborates with consultants, shoring, and waterproofing contractors to ensure a viable and tailored solution that aligns precisely with the client’s expectations.

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..
