Webuild lands $1B contract as cities confront aging sewer systems
The Ohio River Tunnel project in Pittsburgh has been awarded to Lane Construction under a contract worth about $1 billion. The tunnel is part of a wider wastewater infrastructure program designed to reduce sewer overflows, improve water quality and address challenges linked to aging urban water networks.
Lane Construction secured a $1 billion contract for Pittsburgh's Ohio River Tunnel project, a wastewater infrastructure upgrade that reflects growing investment in aging water systems and overflow reduction measures.
Key Highlights
- Lane Construction won a contract worth approximately $1 billion.
- Ohio River Tunnel project aims to reduce sewer overflows during heavy rainfall.
- EPA estimates U.S. wastewater infrastructure needs exceed $630 billion.
- Project forms part of Pittsburgh's broader wastewater modernization program.
- Webuild reported a backlog of more than €58 billion in 2025.
Lane Construction, the U.S. Webuild (Italy)'s unit will build the main wastewater tunnel for Ohio River Tunnel, to a total amount of 1 billion USD (925 million).
The contract, awarded last week, arrives at a critical juncture when water utilities are facing increased pressure to update old water networks and to tackle the pollution problem caused by combined sewer overflows in extreme weather conditions.
A tunnel central to an extended cleansing program
The Ohio River Tunnel project is the centerpiece of a sustained regional endeavor to minimize the amount of combined sewer overflows into the local water systems whenever significant rainfall occurs.
The new tunnel would provide additional underground storage and transportation capacity, storing the overflow of wastewater before the waste is dumped into the local rivers and streams.
The award, announced last 3 rd of June, represents one of the largest water infrastructure contracts awarded in Pennsylvania to date.
Water networks need greater investment
The timing of the award of the Ohio River Tunnel project is representative of the challenge posed by urban water networks dating back decades.
According to the last Clean Watersheds Needs Survey by the U.S. Environmental Protection Agency that was published in 2023, the country requires at least $630 billion to upgrade its wastewater networks during the next two decades.
Similarly large-scale investment programs are currently running in other countries, with Australian water authorities continuing to develop their long-term infrastructure investment programs to strengthen wastewater treatment, storage and network resilience against population increases.
The Ohio River Tunnel project exemplifies how large-scale underground storage tunnels are proving an effective solution for urban areas to achieve the reduction in sewer overflows and to fulfill their environmental obligations.
Contract enhances the current backlog of infrastructure works
The Ohio River Tunnel project also helps bolster Webuild's presence in the water sector, a field which continues to attract significant public investment irrespective of the pressures exerted upon other construction market areas.
Webuild achieved revenues of 13.6 billion in 2025 (up 6% compared to the year before) with EBITDA of 1.16 billion (up 9% year on year). Its backlog stood at over 58 billion at the end of last year.
Webuild operates globally throughout North America, Europe, the Middle East and Australia via an extensive portfolio of transportation, water and civil engineering projects.
The Ohio River Tunnel project constitutes a vital element of Pittsburgh's ongoing endeavor to improve its long-term water quality.
