That does not appear to be the case. A friend of mine spent a considerable amount of money a few years ago to build a wastewater treatment system on his property. Then the gmina told him that, under new legislation, he would still have to connect his property to the common sewage system. This is something that he and many of his neighbours were reluctant to do, because it brings new monthly service charges. He tried to argue his case and managed to stall for several months, but eventually he was forced to do so lest he be fined.

I have heard villagers in Spain and Italy complaining about the same thing, so I assumed there was a new loi communitaire.
