Saudi Arabia rail stations receive advanced stormwater solutions for flood prevention
Hydro International has provided stormwater attenuation and underground storage as part of the Al Haramain Mecca-to-Medina rail project in Saudi Arabia, securing high-capacity flood prevention for the new stations in one of the country's most prominent infrastructure projects.
Dec. 3, 2014 -- Hydro International, a supplier of water, wastewater and stormwater treatment and control technologies, has provided stormwater attenuation and underground storage as part of the Al Haramain Mecca-to-Medina rail project in Saudi Arabia, securing high-capacity flood prevention for the new stations being constructed in one of the country's most prominent infrastructure projects.
In contracts totaling $5 million to date, Hydro has provided geocellular stormwater storage along with Hydro-Brake Optimum® flow controls for underground stormwater storage tanks for the Jeddah and King Abdullah Economic City Stations. The solution is a major success for Hydro following the signing of an official agency agreement with Jeddah-based Centex Arabia, part of the Alkhorayef Group of Companies.
More than 18,000 m3 of storage has been created in seven underground tanks with discharge to the sewer network controlled at 270 l/s by a Hydro-Brake Optimum vortex flow control. Geocellular storage blocks from Hydro provided the best solution available to cope with peak storm flows and high sediment content in stormwater runoff.

The Hydro storage block offered significant advantages over other underground storage options considered for the project because of its perforated distribution pipes. The technology is designed to prevent sediments suspended in the stormwater from entering the storage tank and instead wash them through the pipe network. This means the storage tank is effectively self-cleansing and requires minimal maintenance.
Due to the unique sizing capabilities of Hydro-Brake Optimum, engineers were also able to minimize the storage area required on site, thus providing savings on construction costs. Construction of the 449.2-km high-speed Al Haramain railway began in 2009 to link the cities of Medina and Mecca via King Abdullah Economic City, Rabigh, Jeddah, and King Abdulaziz International Airport.
