Set along Jeddah’s prestigious Corniche, Trump Tower Jeddah is an iconic 47-storey luxury tower designed to redefine high-end urban living on the Red Sea. Developed by Dar Global Holding, this landmark project required innovative engineering and geotechnical strategies — particularly in managing groundwater in a coastal environment with a high-water table.
With the groundwater table encountered just 4.25 metres below ground level, and the site composed of silty sands and coral-rich layers, the project faced significant excavation challenges. Proximity to the Red Sea further complicated hydrogeological behaviour.
Reliable groundwater control was critical to enable safe and timely excavation for substructure and foundation works.
WJ Saudi was appointed by Edrafor Al Arabiya to deliver a full dewatering solution, from site investigation to system design, installation, and operation. With a strong track record in groundwater management across Saudi Arabia, WJ Saudi mobilized in July 2025 to begin project implementation.
Before finalizing the dewatering system design, WJ Saudi conducted a comprehensive pumping test on site. This test was crucial to:
The results from the pumping test directly informed the engineering design, ensuring a fit-for-purpose dewatering system tailored to the site’s unique coastal conditions.
WJ Saudi deployed a hybrid dewatering solution combining deep well dewatering, surface trenching, and recharge management, optimized based on the pumping test data.
A comprehensive surface trench system was installed to manage shallow groundwater and surface infiltration:
This trenching network acted as an additional safeguard during heavy rains or unexpected seepage.
The system operated as a closed-loop, minimizing environmental discharge and supporting aquifer stability:
Building adjacent to the Red Sea introduced unique constraints:
WJ Saudi’s integrated approach, grounded in data from the pumping test, enabled the team to deliver a system that was technically resilient, environmentally sound, and operationally efficient.
The Trump Tower Jeddah project highlights WJ Saudi’s capabilities in data-driven dewatering system design. By conducting a pre-design pumping test, and implementing a combined deep well and trench network, WJ Saudi delivered a robust groundwater management solution tailored to one of Jeddah’s most complex sites.
Whether for high-rise construction, infrastructure, or coastal development, WJ Saudi remains the trusted name in deep well dewatering and groundwater control in Saudi Arabia.
