No, it is not compulsory anywhere to fit holding tanks, only restrictions on discharge in some places like Turkey which make holding tanks necessary if you want to use a toilet on board.
Here in Finland holding tanks are compulsory as we don't have the Atlantic Ocean to flush out waste out of sight – and we really do sail in world's most polluted sea area.
The discharge station network is pretty good at least in Gulf of Finland area. But fitting a holding tank to an old boat can be expensive business, just ask how I know.
