On 18 June 2021 , we will be carrying out utility investigations along Herlwyn Avenue. We will undertake surveys of the manholes in the area, 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.Your utility services will not be affected. <a href="https://www.hs2.org.uk/work-items/notice-of-utility-surveys-on-herlwyn-avenue/">For further information please see our works notification.</a> If you have a question about HS2 or our works, please contact our HS2 Helpdesk team on <a href="tel:08081434434">08081 434 434</a> or email <a href="mailto:hs2enquiries@hs2.org.uk">hs2enquiries@hs2.org.uk</a> .
