Sludge Mains

Scope of Works

Replacement of the existing 230m twin Sludge Main running along wall and steelwork gantry over the road.

  • Installation of new sludge pipe, jointing, welding 460m of 315 SDR17 pipework

  • Installation of 8 No Steel Bellows Expansion joints

  • Installation of 230m of Armco barriers

  • Drain down existing pipes, remove sludge, and dispose of pipes offsite for recycling

  • Installation of 5mm Aluminium pipe cladding

Challenges

One of the biggest challenges to overcome for GEL on the project was the design, pipe expansion ‘behaviour’ and installation of a new ‘sludge main’ whilst one line of existing sludge main remained ‘online’. This was completed without delay to the project and without any downtime to the Sewage Treatment Works, which happened to be the biggest n Europe.

Our Responsibility

Working closely with The Client, GEL proposed changes to the existing sludge main to enhance quality and sustainability. The new sludge main was constructed using pipe made from recycled plastic with old pipework sent for recycling; the solution was, therefore, environmentally friendly as well as cost effective and sustainable.
