Engineered Solutions for Minimal Disruption
Upgrade works for the temporary sewage bypass project
Description:
As a trusted supplier for sewage and stormwater bypass and over pumping services in the Middle East, it’s not uncommon for clients to contact WJ Saudi when regular upgrade works are required. On this occasion, the ADSSC (Abu Dhabi Sewerage Services Company) contacted us to assist with the required works for a temporary sewage bypass in the Al Samha region.
To complete these works effectively, WJ bypassed two main inflow networks to the pumping station by using a combination of high capacity diesel, and submersible pumps. The flow was controlled in the range of 500-1000m3/hr to provide a sufficient and safe solution for the client.
WJ used up to 100m (linear distance) of temporary, but robust, HDPE discharge lines to successfully divert the flow with no impact to the main network and surrounding residential areas. Using HDPE lines as opposed to layflat hoses means a reduction in friction, and therefore reduces fuel consumption meaning smaller pumps can be used.

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..
