93% of residents agree it’s important to take action now to address the impacts of climate change 

We asked residents what they thought about the risks of flooding and droughts. There is strong support for projects that would make Southend and Thurrock more resilient to the effects of climate change.

This includes innovative new approaches like leaky dams and rainwater harvesting systems as well as traditional engineered solutions like groynes and sea walls.

Our catchment

We’re taking a catchment-based approach in this project. This means that we’re considering the entire journey of water, from when it falls out of our skies, to when it reaches the sea at our coast.

Upper catchment

We’re using innovative measures to keep water on the land longer and slow the flow down through the catchment to urban areas.

Middle catchment

We’re capturing, storing, treating and re-using rainwater to improve flood resilience and reduce demand on our mains water supply.
