The water that runs off our traffic-filled roads ends up in our rivers, but we know little about it, it's hardly monitored and improving the quality of that runoff is a huge task.

Join us for this special episode of Planet Possible in collaboration with Watershed Investigations as we dig into the realities of highway runoff . . We’re joined from the front line by Jo Bradley from Stormwater Shepherds as she carries out water quality testing and hear from both National Highways, who own the strategic road network and the Environment Agency, the environmental regulator in England.  

We explore how we manage these flows and what the future looks like - and of course we’ll offer our guests the Planet Possible magic wand too.

Post-interview clarification on behalf of National Highways:

”National Highways developed its water runoff risk assessment tool in partnership with the Environment Agency, and it was agreed it was fit for purpose. Similarly, on the M6 J21A-26, seven Vortex Separation Chambers have been installed as part of upgrade work to keep pollutants in check. Along with drainage, these devices use hydrodynamic separation to capture and retain insoluble particles such as silt, hydrocarbons and debris from the surface water systems.”
