"That argument [for nature-based solutions that keep stormwater in the ground] has to an extent been won."

This is according to Clare Donnelly, lead architect on the Thames Tideway project to divert sewage outflows from London's main river.

The podcast host asks her about working with others such as city planners to boost more development projects that can absorb stormwater on site rather than rely on grey infrastructure tunnelling. 

She replies with some encouraging news for those working with city staff anywhere: nature-based solutions are the future, and are happening already, in the UK.

This for the podcast The Urbanist by Monocle magazine.
