The French A1 2009 rules insist that a sewage treatment plant is tested at 200% of its design load criteria, with a maximum of 3 failures.
The ordinary EN 12566-3 test only tested at 150% of the design load criteria, which France decreed was not enough.
France also insists that all plants are tested for use as weekend homes - the plants have no load for 5 days and full load for 2 days - for several weeks during the test period.
Most of the UK plants sold as "OK for France" because they have the ordinary EN 12566-3 2005 Certificate, actually aren't OK at all.
The BIOROCK has passed this very stringent French A1 2009 test and is now fully compliant with French regulations.
The BIOROCK agreement number is 2010 - 026

You will see that the Biorock is approved and has the Agrement Number 2010-026
Will post if it doesn't work!
I was told that if it isn't on the 'approved' list, you can't put it in.
