Ten locations across London have been singled out for cash that will be used to clean up waterways and promote wild swimming.
Sir Sadiq Khan on Wednesday announced his 10-year plan to clean up the capital’s rivers, which he said had suffered from "decades of neglect and pollution".
A total of £1.8 billion has been pledged by water companies, boroughs and charities, with City Hall adding a further £2.7 million across three years on top of the £13.6 million already promised.
The money will be used to build new parks, clean up waterways and improve wildlife habitats.
Sir Sadiq told the Standard: “We've identified 10 locations across our city where we want to see swift progress.
“Swift progress in reducing pollution, swift progress in reviving nature, but also swift progress in revitalising and restoring access for local communities to those blue and green spaces.”
The ten areas which will receive cash are:
