HS2 survey may involve Aylsham Drive

Estimated Start Date


Estimated End Date


From HS2

We wrote to you in April 2021 to let you know that we would be carrying out sewer investigations near Blenheim Crescent. We need to re-visit this location to carry out additional works that will take place on 28 January 2022. The location of these works is shown on the map overleaf.

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 to carry out the investigation.

It may not be possible to carry out the investigation in the works area shown on the map because of proximity to railway lines. As an alternative, we will be able to undertake the investigation via a manhole located nearby just off Aylsham Drive via the car park (see map). https://www.hs2.org.uk/work-items/notice-of-utility-surveys-near-blenheim-crescent-3/

How the surveys might affect you

You may see people working along the railway tracks. We may need to carry out the works via the manhole in the open space next to 259-329 Aylsham Drive. If this is the case, there will be operatives carrying out the survey at this location. Your utility services will not be affected.
