3839 Fossa biologica

Does anyone have any idea of how often a fossa biologica should be cleaned? There are two of us living here full-time, and before us, the owner only used the house sporadically. He never cleaned it, and it was installed around 20 years ago.

Incidentally, any generalisations about how to maintain / use / keep it working well would be very much appreciated.

Many thanks for this! My head is spinning from reading it all. At least I know now that a fossa biologica is a septic tank.

We share a fosse with our neighbours - the general rule for us is that if there is a smell of raw sewage in the street drains [where our fosse overflow goes to [this drain then flows into a nearby stream], then the fosse has stopped 'digesting' and needs pumping out [The local farmer does this and then spray it all over the field his cows graze in - his home produced cheese seems fine]

You can 'assist' the digestion process in a few simple ways to extend the time between cleanings -
1. don't use bleach or biological washing powders,
2. add a 'fosse booster' to encourage digestion [WC Net is the one we use - they also do bathroom cleaners suitable for use with fosses]

If you do this, they can go for years without pumping out
