Roxtec seals chosen for £220m water treatment project WITH PIC

Posted: Monday 21st April 2014

Cable seal manufacturer Roxtec has won a major contract to supply a 220m water treatment upgrade project in London.

The Bury-based company is supplying multi-cable transit seals to Thames Water for its Crossness Sewage Treatment Works which is the second largest in Europe.

The major project will enable the site east of the capital, which is situated on a nature reserve, to treat 44 per cent more sewage than its current capacity.

Roxtec UK managing director Graham O'Hare said the company's seals are being used throughout the site to help protect one of Greater London's last remaining grazing marsh lands.

"Our seals can withstand extremely high water pressure to prevent water ingress which is vital in a project of this nature," Mr O'Hare said.

"They are being used to seal power and control cables in the water works, a thermal hydrolysis plant and a wind turbine. The gas tight seals are also helping to protect local wildlife by preventing sewage from entering the River Thames while guarding against fumes."

Mr O'Hare said Roxtec's seals have been chosen because of the company's proven track record on utilities projects. They have supplied many electrical substations and onshore windfarms worldwide. The round seals are easy to install and Thames Water can use the cable seals in upgrade projects.

"The IP67 rated, multi-hazard seal simultaneously guards against water, gas and fire and are designed to be durable and last a long time," Mr O'Hare added.

"It will also aid Thames Water in protecting its assets against other hazards such as vermin. We are pleased to be chosen to supply such a vital project for the long-term benefit of both the environment and residents in the South East."
