28 Sep G4S wins £50 million contract to provide security for London’s “Super-Sewer”

G4S has won a seven-year contract valued at £50 million to provide security at 21 key sites where the Thames Tideway Tunnel is being constructed.

The proposed 25 kilometre tunnel is London’s biggest investment in sewerage in over 150 years, and will prevent roughly 20 million tonnes of untreated sewage from being discharged into the River Thames each year.

When construction is at its peak, G4S expects to have up to 330 employees working to protect the £4.2 billion construction. In mid-August, Accenture was also brought on board – the company’s cloud-based ERP software is being used to support financial planning and procurement throughout the lifetime of the project.
