Environment Agency strengthens Romsey flood alleviation scheme with new defences

The Environment Agency has completed two significant improvements to the Romsey flood alleviation scheme, reducing flood risk and disruption for local communities.

Romsey flood alleviation scheme Stockbridge Road raised

The Agency has raised the height of Stockbridge Road near Timsbury and added a permanent, demountable defence where weed cuttings are caught.

Working in partnership with Hampshire County Council, the Environment Agency raised the surface of Stockbridge Road near Timsbury by around 40 centimetres late last year.

This creates a passive barrier that requires minimal operation to deploy. The raised surface prevents floodwater from overtopping the road, containing it within the floodplain without the need for temporary barriers or road closures.

The improvement has already proved effective. During last winter’s high-water levels, the road would previously have been at risk of overtopping, but no closure was needed. The £300,000 joint investment provides a cost-effective and resilient long-term solution for this location.

Better flood defence for compound which captures weed cuttings

The Environment Agency has also overhauled flood management at the nearby river weed recovery compound, which is used to capture weed cuttings during summer months.

Previously, a gap between the floodwall and flood embankment had to be left open for machinery access, with a temporary barrier installed during flood events. This was time-consuming, required multiple teams, and needed regular monitoring. It could also be less effective due to uneven ground.

That arrangement has now been replaced with a permanent demountable defence: a 25-metre concrete base with demountable uprights and channels, allowing purpose-made aluminium stop logs to be fitted quickly with fewer staff. This provides greater reliability and resilience at the site.

Artur Podsiadly, Environment Agency project manager, said:

Both of these projects will make the scheme more resilient to future flood events.

Because the measures are passive or quicker to deploy, we can use our resources more efficiently when water levels rise.
