Septic tank.. whats that laugh2 We upgraded our septic tank to a twin tank air injected sewage treatment system 3 years ago.. I did not complain as I do believe it was the correct thing to do.. The blurb says its outfall is drinkable, but I will miss testing on that one... xmasbigsmile. Ironically, the air injection needs a reliable electrical supply...
