Over the winter of 2017/18, Essex & Suffolk Water, in partnership with Essex Waterways, will be replacing the sea lock gate and central timber mitre gates at Heybridge Basin in Essex. The project will involve the closing and draining of the lock in October 2017, crane lifting operations for the gates and the assembly and testing of the new gates prior to the re-opening of the lock in March 2018. There will be disruption in the area during this work period but we will endeavour to keep this to an absolute minimum.

Start Date

September, 2016

Estimated End Date

March, 2018

Update by Adrian Caswell

Hi All,

As an update to the ongoing work at Heybridge, the cofferdam installation encountered unforeseen conditions and as a result the required depth to embed sheet piles was not achieved. We are currently exploring alternative solutions to achieve a dry lock scenario as soon as possible.

We are not anticipating any delays to the project at this time .I attach an image of the cofferdam for information.

I will provide an update as soon as the solution has been agreed. Please feel free to contact myself or a member of the team for further information.


Best regards,

Adrian Caswell
Project Manager
