The Metropolitan St Louis Sewer District (MSD) has selected a Black & Veatch-led team to manage the construction of more than $500 million in future tunnel projects. The tunnels are a significant part of the MSD’s Project Clear – a long-term, multi-billion dollar effort to address sewer overflows and basement backups throughout the St Louis area, in Missouri, US.
The Black & Veatch-led team is responsible for construction management of up to seven different tunnels across MSD’s service territory. These tunnels will range from nine feet in diameter to more than 20 feet. The longest tunnel will be nearly seven miles long. All tunnels will be approximately 150 to 250 feet below the surface. It will take approximately 15 to 20 years to complete all of the tunnels.
“Black & Veatch has a proven approach and successful track record regarding construction management of rock tunnels, particularly ones in karst formations such as the tunnels in progress for MSD,” said David Egger, Senior Vice President in Black & Veatch’s water business. “Deep tunnels provide a long-term solution for combined sewer overflows and sanitary sewer overflows in a manner that preserves community aesthetics and property values. Although each present major engineering and construction challenges, Black & Veatch has been successful at mitigating risks for our clients and keeping projects on schedule.”
