Bridgwater Tidal Barrier Scheme

Bridgwater, Somerset, is located on the River Parrett estuary, about 17 km upstream of the Severn Estuary. Much of the town and its surroundings lie below high tide level, placing 11,300 homes (60% of the housing stock), 1,500 businesses, and key infrastructure at risk of tidal flooding.

The Bridgwater Tidal Barrier (BTB) Scheme will better protect these 11,300 homes and 1,500 businesses from tidal flooding in Bridgwater and nearby communities. It will also provide £2 billion in benefits to the local area, forecasting to deliver £7.50 of benefits for every £1 spent.

The cost of the whole scheme, including the barrier, operational site, downstream flood banks at Chilton Trinity, Pawlett and Combwich and 12 upstream sites with improved fish and eel passage, is £249 million.

The Bridgwater Tidal Barrier Scheme, is a flood protection initiative designed to reduce this risk by constructing a tidal surge barrier and associated downstream defences. With a design life of 100 years, the Scheme not only protects the community but also creates an environmental corridor featuring wetlands and heritage elements, linking both sides of the river.

Managed by the Environment Agency (EA) and Somerset Council, with support from the Somerset Rivers Authority (SRA), the Scheme forms a key part of Somerset’s 20-year Action Plan, accelerated after the devastating 2013-14 floods.
