News on HS2 in Hillingdon

From 6 to 9 April 2021 , we will be carrying out sewer system investigations along the rail tracks south of Blenheim Crescent. This will help to inform our design decisions in the area.

We will investigate the condition of the sewer system using a CCTV camera mounted on a small robot. Should we find a blockage, we may need to flush the drainage system using a high-pressure water jet in order to carry out the investigation.

To ensure the safety of operatives and rail users, these works will take place at night during a rail possession.

Your utility services will not be affected.

For further information please see our works notification.
