Hydro International completes work on Al Haramain Mecca - Medina Rail project

Posted on 4th December 2014

Hydro International has provided stormwater attenuation and underground storage as part of the Al Haramain Mecca to Medina rail project.


The company has secured high-capacity flood prevention for the new stations being constructed in one of Saudi Arabia's most prestigious and far-reaching infrastructure projects.

In contracts totalling US$ 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, according to news reports on Construction Week Online.

More than 18,000 cubic meters of storage has been created in seven underground tanks with discharge to the sewer network controlled at 270l/s by a Hydro-Brake Optimum® vortex flow control. Geocellular storage blocks from Hydro International 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 minimise the storage area required on site, thus providing savings on construction costs.

Hydro's Middle East Sales Manager, Ezzat Natsheh comments: "Providing robust protection to prevent flood damage to new infrastructure is a high priority for the Saudi Government. Heavy sand and silt loadings, combined with high peak rainfall events are typical of the Saudi Arabian climate. So identifying the best technologies from around the world to address the country's needs is essential.

"Hydro International is extremely proud to be working on one of the Middle East's most prestigious infrastructure projects and we are pleased that our technologies can help efforts to improve flood prevention in Saudi Arabia and throughout the Middle East."

Construction of the 449.2 kilometer high-speed Al Haramain railway began in 2009 to link the Muslim holy cities of Medina and Mecca via King Abdullah Economic City, Rabigh, Jeddah, and King Abdulaziz International Airport.
