Super sewer security

The official opening of London’s new multi-million pound ‘super sewer’ has triggered the installation of high security perimeter protection for its main access points. The points are being secured by perimeter security expert Zaun, with its most intruderresistant product, ArmaWeave, with double leaf gates.

It is being installed by Zaun subsidiary Binns Fencing, who is working with main contractor MVB, a joint venture comprising Morgan Sindall, VINCI Construction Grands Projets and Bachy Soletanche.

ArmaWeave’s unique properties add substantial resistance to cutting attacks with hand, powered and non-contact tools. The tight mesh pattern provides no climbing aids, again limiting the potential for intrusion.

Former Mayor of London Boris Johnson opened Thames Water’s extension to the Lee Tunnel by flushing a toilet in an underground ceremony, declaring the £678 million project ‘an amazing achievement for British engineering’.

The 4.3 mile-long Lee Tunnel extension took four years to build and is designed to stop sewage flushing into the River Thames and River Lee. It will be followed by the construction of an even larger sewer, the Thames Tideway Tunnel, later this year.
