Start & Completion
Due to start in January 2026
The Eau Brink Tidal Outfall plays a vital role in managing water levels and reducing flood risk within the surrounding low-lying fenland. This wider area is highly influenced by tidal conditions and relies on well-maintained infrastructure to protect communities, farmland and sensitive environmental habitats.
This project forms part of ongoing investment in resilient flood and water management assets across the catchment. It has been made possible through funding from Defra’s IDB Storm Recovery & Asset Improvement Fund.
Overview
In early 2026, works will be carried out to upgrade the tidal outfall structure at Eau Brink. The existing tidal sluice doors have reached the end of their serviceable life and will be replaced to ensure the continued reliable operation of the outfall.
The structure currently includes a water retention penstock. However, this does not provide effective protection to the upstream fen should the tidal (pointing) doors fail or become blocked by debris, which could allow tidal water to enter the catchment. To address this risk and improve overall resilience, the penstock will be replaced with a full-height structure capable of retaining the tide if required.
The scheme has been designed by Stantec UK Ltd, with construction works delivered by Martin Childs Limited. The WMA Project Delivery team will oversee the works, ensuring the scheme is delivered efficiently and cost-effectively.
Benefits
Once complete, the upgraded tidal outfall will provide improved flood protection for the upstream fen and surrounding area, reducing the risk of tidal flooding during extreme conditions.
The project will enhance the long-term resilience and reliability of the water management infrastructure, supporting local communities, agriculture and the wider environment. By strengthening the outfall’s ability to manage tidal influence, the scheme will also contribute to more sustainable water level management and help protect valuable habitats within the catchment.
