Bridgwater Tidal Barrier design review cuts costs and boosts efficiency
Updated plans will streamline construction while keeping flood protection levels high
Plans for the Bridgwater Tidal Barrier have been updated following a design efficiency review by the Environment Agency, aiming to reduce costs and simplify construction without compromising flood protection for 12,800 homes and businesses.
Changes to the barrier’s superstructure include reducing the towers’ height by 10 metres to 15 metres, simplifying their design, and relocating drive equipment to the base of the towers, where it will be easier to maintain.
The use of lighter walkways instead of an overbridge will also reduce long-term operating costs.
Ross Barton, project director for the Bridgwater Tidal Barrier scheme, said: “The review outcomes have strengthened the delivery of the scheme.
"It confirms we can deliver the same high level of flood protection in a more efficient and affordable way, while keeping construction moving and creating a lasting benefit for local communities.”
Somerset Council leader Bill Revans added: “The Bridgwater Tidal Barrier Scheme is vital to the future of our communities and local economy.
"We welcome this responsible approach, which maintains flood protection while ensuring the scheme remains affordable and on track.”
Recent progress and funding
Significant progress has already been made, with work on the barrier substructure and downstream defences underway.
Construction began in early 2023, and ongoing work will span over the next 5-6 years, including landscaping.
The barrier aims to protect against a 1 in 200-year flood—meaning a flood event with a 0.5% probability each year—until at least 2125 for Bridgwater and 2055 for nearby areas such as Combwich.
The project has secured £249 million in funding, including approval of its business case since September 2024. Efforts to optimise every pound spent are underway, with the final cost expected to be announced following additional government reporting later this year.
Community sessions to explain designs
Two public drop-in sessions will take place in January to discuss the project’s updated designs. Attendees will be able to see the progress to date and ask questions about how changes impact the scheme.
Session details:
- Wednesday 21 January 2026, 5pm to 8pm at Chilton Trinity Village Hall, Chilton Trinity, Bridgwater, TA6 4PL
