Yeah, I didn’t think about this before but I guess you need to be careful if you have water from a bore hole. I didn’t realise that safe distance was only 30m! But I’m also under the impression that septic systems are quite carefully designed, not just a big hole soaking blackwater into the ground.
Everyone I know on septic systems gets their water from rainwater (something we get a lot of here) so contamination isn’t a problem.
A proper septic system is carefully engineered but they can still be quite low tech. Many houses still just have gravel trenches and pits.
My own home doesn’t have any pumps, it just pushes water out as water comes in. My tiny strip of land has deep trenches and the right native soil (deep sand).
More modern systems just need some pressurized lines and only three feet of the right sand to achieve proper treatment of effluents.
