Public graves are used for more than one burial. They have economic and ecological benefits. The first coffin is buried at a two-metre depth, allowing space for a second coffin (of an unrelated person) to be buried after five years.

No permanent memorials are permitted. A wooden cross may be used to demarcate the first burial, but the City may remove it after five years to enable a second coffin to be buried and a new cross to be installed.
