Young children were spotted playing and laughing in the bubbly scene with footprints scattered around the fountain.
People on social media have raised concerns about the expected cost in cleaning up the foam – and its impact on unsuspecting birds who might drink from the fountain.
Simon Fisher, town clerk for Devizes, explained a lot of work would go into rectifiying the situation.
The fountain has been drained
He told the Gazette: "We've drained the fountain and we'll have two guys go back tomorrow to have a look and see about refilling it.
"It takes a long time to drain it out completely and make sure it's properly clean."
