What happen in other places abroad , is it the same as here running out of ground ?
What they do in Germany is the authorities lease the plot for 20, 25 or 30 years, depending on the constitution of the ground. After this time runs out, you are given the option of extending the lease . If you decide not to, the plot is then reused, the headstone then being returned to you for whatever you want to use it for.
A bit gruesome I thought, until I had to design a water supply line next to a "live" cemetery, whereupon I had to make certain enquiries with the authorities. Usually lime is put into the grave before its filled in, hence the contents are dissolved within about 10 years and nothing is left when its reopened. Except in certain cases, where there is a lot of clay around, then the lease is simply extended, or more lime is put in at the time of burial.
The headstone can be sold or given back to the stonemason , who polishes off the script and resuses the stone, or the stone is put with other stones to one side of the cemetery.
I spoke to my mother (still in Wales) about this and she informed me that my grandmother had bought a 99 year lease for the plot when my grandfather died. So I assume the plot will be reused once it runs out, if no-one extends the lease.
By the was, did you know that the bones have to be ground after cremation so that they fit into the urn? Cremation only gets rid of the organic materials, not the calcified remains. Burning is definitely not my cup of tea.
