This is the latest we have from the council:
I know you will be concerned about the on-going works but I regret to inform you that following additional survey works, we have reluctantly accepted that further works are needed to repair yet another section of the collapsed sewer. Consequently, excavation work near the junction with Cottingham Road is underway, with the third set of repairs to the sewer completed. The latest ‘collapse’ was not seen on previous CCTV surveys as there was a blockage in the sewer preventing the remote camera getting that far.
This latest work will take around four weeks to complete, with current traffic management measures staying in place. We have said that this work will break the Christmas moratorium of works that we try to abide by but the seriousness of the collapse has led Thames Water to conclude that the work needs to completed now, asap. It is worth remembering that it was the collapse and discovery of the void that started this whole incident.
The council, and local councillors, have seen a photo which clearly shows the brick work loose, with the darkness being a void behind the bricks. We do not have permission to publish this photo but it does illustrate the problem. The council adds:
Also, as possibly a pre-warning, the Thames Water contractor is concerned about the complete lining of the sewer as the mortar/cement is loose elsewhere – there is a possibility that further works will be necessary at some stage in 2014 and this potentially would be from the first excavation point north to the Croydon Road junction and South to Kenilworth Road. If this is formally raised by Thames Water, we will come back to you but it is worth being aware of this.
Clearly this news will be very difficult for businesses and ultimately, this will be a Thames Water issue to resolve but in the circumsatnces, we have to accept the Thames Water advice of the seriousness of the problem.
If we receive progress update reports, we will continue to let you know.
