Flood Protection Services

At Radian, we specialize in flood modeling and simulation, as well as designing effective alternatives for flood hazard protection. Our team employs advanced methodologies to assess flood risks and develop tailored solutions that safeguard communities and infrastructure.

Tunneling Method Overview

The tunneling method is recognized as a safe and efficient approach for implementing large-diameter and deep pipelines that are challenging to construct using traditional methods. This technique is particularly beneficial for projects related to stormwater drainage and flood hazard mitigation, as it allows for the installation of pipelines at significant depths while minimizing road disruptions. It is also utilized for sections of flood control lines that intersect major roads, ensuring that essential transportation routes remain operational during construction.

Stormwater Drainage via Horizontal Directional Drilling - Costing Over SAR 550 Million

This ambitious project aims to channel stormwater from Naka Lakes to the Wadi in Buraydah. It effectively manages runoff from the Eastern Bridge using a 2500 mm diameter pipeline along King Abdullah Road, directing excess water to the Wadi. The system serves a significant portion of the eastern area of the city, including neighborhoods such as Ar Rabi, Ar Rubwah, An-Nur, and An Nuqaa, which host critical facilities, including the King Fahd Specialist Hospital.

The flows are pumped through two stations with a combined capacity of up to 9,100 l/s into three lakes: Al Mushtal, An Nuqaa, and Workers Housing Lake. These lakes boast a total storage capacity of 1,372,800 m², allowing them to initially store rainfall during storms to absorb peak flows. The water is then discharged through 3500 mm diameter horizontal directional drilling lines, which run at depths ranging from approximately 13.0 to 60.0 m, covering a total length of about 9.85 km to the discharge point at Wadi Ar Rama.

Additionally, water is pumped from the pipeline to the Wadi through a pumping station with a capacity of 27,180 l/s. The project also includes connecting rainwater networks from neighborhoods along the route—such as Al Waseeta, Al Rafiah, Ad Dahi, and Al Bassateen—to the Eastern Inner Ring Road, enhancing the overall efficiency of the stormwater management system.
