Amber Infrastructure related entities, Allianz and Dalmore take further stake in Thames Tideway Tunnel

June 06, 2022

London - Paul Hastings LLP, a leading global law firm, advised specialist infrastructure fund manager Amber Infrastructure and its related entities International Public Partnerships Limited (INPP) and Swiss Life Asset Managers, alongside co-shareholders Allianz Capital Partners and infrastructure fund manager Dalmore Capital Limited, on the purchase of a 10.66% shareholding in the Thames Tideway Tunnel from DIF Capital Partners.

The Thames Tideway Tunnel is a unique UK infrastructure project and is the largest single asset in the UK water sector. The 25km long tunnel is being constructed to help prevent the release of 37 million cubic metres of untreated sewage that is currently discharged into the River Thames in a typical year. The ‘super sewer’ will significantly increase the capacity of London’s sewer network and help to transform the River Thames into a healthier and cleaner river.

The Paul Hastings team was led by Energy and Infrastructure M&A partner Steven Bryan, Energy & Infrastructure Finance partner Derwin Jenkinson and associates Tamsin Doran and Tara Gazzard in London, alongside Financial Regulatory partner Arun Srivastava and associate Nina Moffatt in London, and Merger Control partner Pierre Kirch and associate Juliette Hua in Paris.
