Our fosse septique has to be 'SPANC'd before the 18th of December. I have just found the facture given to us by the previous owner it is not up to current regulations (it has a 2000L tank and not the 3000L minimum)
My question is, how long might we be given to replace the fosse? We haven't had any problems with our water or experienced any nasty smells and It's money I would rather spend on other parts of the house at this stage...
We only use the house for about 12 weeks of the year, will this have any bearing on the matter?
