Security Perimeter Fencing Systems Added To Thames Water Super Sewer Chambers
Raised chambers housing flow gauges for London’s new multi-million pound ‘super sewer’ have been secured with intruder-resistant Security Perimeter Fencing Systems .
Thames Water’s extension to the Lee Tunnel was opened earlier this year by Foreign Secretary Boris Johnson before he departed his former role as London Mayor.
The 4.3 mile-long £678 million project took four years to build and was designed to stop sewage flushing into the River Thames and River Lee.
Perimeter security expert Zaun had already secured the access points to the tunnel extension with its most intruder-resistant product, ArmaWeave, installed by Zaun subsidiary Binns Fencing.
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.
Zaun designed two bespoke ‘cages’ from ArmaWeave with special fixings and topped with 980 razor coil to protect the flow gauge chambers.
On average 39 million tonnes of untreated sewage mixed with rain water gets discharged into the River Thames from overloaded treatment works and combined sewer outfalls every year.
The biggest of these outfalls, at Abbey Mills pumping station, has been discharging 16 million tonnes of sewage per year to the River Lee.
The £678 million Lee Tunnel – the largest single project in the history of the privatised water industry in England and Wales, and the deepest ever bored under London at 75 metres deep – will capture this sewage to keep it out of the River Lee.
The Lee Tunnel connects the Abbey Mills Water Treatment Centre to Beckton Sewage Treatment Works, Europe’s largest such site, both if which are also secured by Zaun perimeter protection.
The Thames Tideway Tunnel will connect to the Lee Tunnel and will capture sewage from the remaining 34 combined sewer overflows, keeping it out of the River Thames.
Zaun raids rival for champion Bailes
The Zaun Group has secured an industry champion from a market leader to spearhead selling its integrated portfolio and turnkey solutions.
Steve Bailes has joined Zaun as integrated business development manager from a similar role for the past seven years with Gallagher Security Europe Ltd.
Prior to that Bailes was at Betafence, where he worked alongside Zaun head of sales Chris Plimley and, among other projects, originated some of the fencing that ultimately Zaun installed for the London 2012 Olympics.
Bailes represented Gallaghers at the British Security Industry Association, working on British Standards in electric fencing and other physical security systems. He also has experience in access control along with perimeter detection incorporating CCTV integration alongside high security perimeter fencing systems and standard fencing for sports and education.
He said: “The Zaun Group’s broad range of products that spans right across my working background massively appeals to me. So I’m looking forward to working together with a team of people to really grow the Zaun businesses.
“That will entail bringing the physical systems together with EyeLynx’s electronics and the contracting option of Binns Fencing to provide turnkey solutions and supply to major clients and customers through long-term relationships.“
