North London Waste Authority (NLWA) has completed its latest construction on sewer diversion as part of delivering a -new sustainable waste hub, the North London Heat and Power Project (NLHPP).

The multi-million pound investment to upgrade the existing sewer system has ‘ensured that London residents will continue to be served by reliable sewer infrastructure for years.’

The Sewer Diversion works were completed in September which has made room for recycling facilities to be brought forward.

An upgrade to the existing sewer system has also been put in place which benefits people of Barnet, Camden, Enfield, Hackney, Haringey, Islington and Waltham Forest.

The contractor has been carrying out engineering works to divert two Thames Water sewers, the Angel and Chingford, which run beneath the future Resource Recovery Facility (RRF) and public Reuse and Recycling Centre (RRC).

Councillor Clyde Loakes, Chair of NLWA said, “I am delighted to see yet another major construction milestone reached on the NLHPP programme.

“These works represent a major step in delivering recycling facilities to help drive our household recycling rate to 50 per cent.

“It is great to see that this contract was delivered to time and budget, whilst also creating valuable employment opportunities for north London residents.’”

Jacques Deneys, Project Manager from Barhale said, “We are really proud of being part of this hugely important project for London which will set new standards for waste management and sustainability.

“Much credit must go to the team for the hard work, engineering know-how and innovation they contributed – not least in the completion of the double simultaneous pipe jack.”

The NLHPP is also delivering an Energy Recovery Facility (ERF), which will use non-recyclable waste as a valuable resource to generate 78 megawatts of electricity.

It will have the capacity to provide low carbon heating and hot water to 20,000 local homes in the Meridian Water Heat Network, with the capacity to supply up to 50,000 connections to the network across the borough and beyond.
