North London Waste Authority tenders £5.7m sewer diversion construction work contract

The North London Waste Authority has gone out to tender with a contract for the design, supply, construction and commissioning of sewer diversion work for the North London Heat and Power Project (NLHPP) worth an estimated £5.7million.

The Authority is seeking a contractor to carry out the works on the existing Angel and Chingford sewers.

The sewer diversion works are part of the North London Heat and Power Project (NLHPP) for the development of a new energy recovery facility and associated works at the Edmonton EcoPark.

A new Resource Recovery Facility (RRF) will be constructed over the existing Angel and Chingford sewers and their confluence manhole. Following Thames Water requirements on the accessibility and endurance of their asset, the prior diversion of approximately 165 m of the Angel sewer and 115 m of the Chingford sewer including the construction of new manhole access points is required to maintain access and allow the RRF to be constructed over the Thames Water asset.

The sewer diversion works are on the critical path for the NLHPP. The sewer diversion works include:

  • tunnelling works for the installation of a 1 200 mm diameter sewer along a stretch of approximately 115 m diverting the Chingford sewer,
  • installation of a 1 200 mm diameter sewer along a stretch of approximately 165 m diverting the Angel sewer;
  • installation of reception shafts at the 2 sewers of approximately 9,0 m deep
  • connection of the new sewers to the existing sewers.

Deadline for receipt of tenders or requests to participate is 7th March 2019 – click here to access the tender documentation.
