Leaking sheet piling causes another sinkhole at Donkere Spaarne: 'This is major'

A sinkhole has appeared on a walking path along the Donkere Spaarne for the third time in 18 months due to a leaking sheet pile wall. Water from the Spaarne river seeped under the pavement, eroding the sand and stones, which has prompted an investigation by the municipality.
