Ham Baker Design, Build and Install the World’s Largest Penstocks for Dubai’s Deep Tunnel Storm Water System

Ham Baker, recognised as the world leaders in Penstock design and build have just completed what are thought to be the biggest and highest specification Penstocks ever built anywhere in the world.

The 3 off 3000mm wide x 5000mm deep Stainless Steel Super Duplex S32750 penstocks that are capable of 63.9 on/off seat pressures are to be deployed in Dubai as part of the Deep Tunnel Storm Water project that commenced construction in 2018.

The Dubai Deep Tunnel Storm Water System is being built by the Dubai Municipality to protect homes and businesses from the impact of flooding and rising groundwater.  The project will drain 40% of the entire urban area of the city. It will serve the whole of Dubai South, which is home to Dubai’s new airport. The system has five elements, a groundwater and stormwater collection network; a 10km, 10m diameter, 45m deep tunnel; a holding pond; high efficiency pumping station; and a sea outfall.

The penstocks, installed and commissioned by the Ham Baker team will be hydraulically operated and will play an integral role in controlling the flow of water in a system that has been designed to handle up to 6.5 million m3 of rainwater, Ham Baker was commissioned with the build due to their worldwide reputation as the experts on Penstock design and build.  

The team at Ham Baker 3D modelled the penstocks using cutting edge design software and the finished penstocks were subjected to rigorous testing in a brand-new facility at the operating site in Stoke on Trent (UK) that is capable of testing Penstocks of this magnitude.

David PyeDavid Pye, Sales and Marketing Director for Ham Baker said of the build:

“ it was rewarding that Ham Baker was approached to provide these penstocks, our legacy and reputation as experts in this field is undoubted and after many months of design and build the team are on the ground in Dubai, installing and commissioning as we speak
