Weholite plays crucial role for Thames Water

Posted: Tuesday 14th January 2014

Asset International Ltd. (Asset), the leading manufacturer of Weholite sustainable drainage and water management products, has been chosen to provide extensive pipe work for the new £190 million upgrade at Beckton Sewage Treatment Works in east London, to help clean up the River Thames.

Water company, Thames Water, in consultation with principal designer Hyder, along with Tamesis, a joint venture of Laing O’Rourke and Imtech, chose Weholite, to provide its signature large diameter HDPE pipes, to implement improvements to the sewage works, which currently serves 3.5 million people. The improvements will enable the site to treat 60% more sewage than it does now and allow for a 10% population increase until 2021.

The improvements to the sewage works will allow for the ability to fully treat increased flows during heavy rainfall, which are currently discharged into the River Thames, to prevent streets and homes from flooding.

The treatment works will have the capacity to cope with additional storm flows from the Lee Tunnel, a new four mile sewer which captures storm sewage that currently overflows into the River Lee when the system is overwhelmed during heavy rainfall. The additional capacity will also be of benefit to the proposed Thames Tideway Tunnel, a major new sewer that will help tackle the problem of overflows from the capital's Victorian sewers, and will protect the River Thames from increasing pollution for at least the next 100 years.

Asset supplied over 5km of Weholite HDPE pipe, in various sizes; ranging from 400mm to 3000mm in diameter. The pipes have been used throughout the extensive project for inter-process pipe work, and all of the associated chamber fabrications.

Shaun Kalies, project manager at Asset, added: “We have worked successfully with Thames Water on numerous projects over the years and to be involved in a project of this scale, along with several others, across the Thames Water sewage management system, is a huge feather on our cap.”
