Independent sanitation systems (FTE) and the new regulations

[Katt]

I wondered if anyone here could help out. The house we are buying has an independent sanitation system (FTE - fosse toutes eaux? and an épandage - soak away?). We have been advised that the regulations regarding independant sanitation systems has changed recently and we have to make sure our system complies.

What are the new regulations and could this be expensive if we don't comply?
