Mancunian Way sinkhole - United Utilities completes £6m sewer repair

United Utilities has now completed a £6 million tunnelling project to lay a new sewer since August when a huge sinkhole appeared after heavy rain, causing major damage to a key sewer.

UU Manc Way shaft March16The water company is currently carrying out further replacement highway drainage work and resurfacing on behalf of Manchester City Council to the Mancunian Way which will fully re-open on Wednesday 15 June.

The scale of the work, which makes this the biggest emergency sewer repair United Utilities has ever undertaken, has included:

  • 10,400 tonnes of sandstone has been excavated
  • The equivalent of 3,992 Olympic-sized swimming pools of sewage have been pumped past the roadworks
  • 400 metres of temporary pipework has been laid
  • 3 of the largest mobile pumps in the UK have been used – each one foot in diameter and capable of shifting 500 litres of wastewater a second, 24 hours a day

Councillor Kate Chappell, Executive Member for Environment for Manchester City Council, said:

“It's great news that we have got a date for the reopening. We'd like to thank the public for bearing with us during this challenging work.”

“As the damage affected a major sewer there was no alternative but for United Utilities to carry out this complex large-scale repair deep underground otherwise large parts of East Manchester would have been left without a functioning sewage system.”

"It's great news that United Utilities have carried out this difficult repair without disruption to water and sewage network and we appreciate all their hard work.”
