Anglian Water is returning to a popular Ely green space to investigate why a newly laid path is sinking into the ground.
A letter dated April 5 has been posted to local residents, informing them that Anglian Water plans to test the area for about three days next week to establish the cause of the slump.
Parts of the path have buckled while others have developed cracks. The worst areas have now been sealed off as a safety precaution.
Anglian Water said: “We completed the construction of a new sewer last year within the open park between Downham Road and West Fen Road. We now need to return to the area to carry out some important investigation work to find out why the path has sunk.”
The park, used by dog walkers, families, cyclists and pedestrians, adjoins Downham Road, Columbine Road, Teasel Drive, Mallow Close and West Fen Road.
It was closed for much of last summer so that sewers could be put in for the new Ely Leisure Village.
After most of the initial work was completed, a new path was laid out across parts of the park – but some of it has now severely subsided, posing a risk to passers-by.
While Anglian Water carries out its tests, its engineers will be working in closed off sections of the verge but the park will remain open at all times.
Once the test results are in, the water company plans to return to the area to complete “the final reinstatement of the footpath”.
