World Heritage Wheelie Bins

Called in at Saltaire this afternoon to pick up more stock of my Greetings Cards - and to have a chat with the lovely AiredaleKnitter and the rest of the Dandy Art House team.
Saltaire is a designated UNESCO World Heritage site along with such places as Machu Picchu, The Taj Mahal and Bern in Switzerland.  I wonder if they have wheelie bins in the streets?
