Members of SWAG, the Seething Wells Action Group have been
trying to save the filter beds on the 14-acre former industrial site.
They say they’re now worried that a wall next to the river
could have been left unsupported.
The owners of the site Cascina have said work is being done
to stop walls collapsing and flooding.
A petition to save the filter beds and turn the area into a
nature reserve has attracted thousands of signatures.
