River Thames Scheme

How the Environment Agency and Surrey County Council plan to reduce flood risk in Surrey and South West London.



The River Thames between Egham and Teddington is on the largest area of undefended, developed floodplain in England.

In the past, the area has suffered serious floods. With climate change, the risk of flooding is only going to grow.

We need a long term, sustainable plan to deal with this risk.

That plan is the River Thames Scheme.
