My grandmothers house has been in the family for 3 generations, is in a rural area, has never has less than 3 people living in it at any time, and has never had to be pumped. Ditto for the septic at my mother's in Indiana, going on 25 years there now. I HAVE seen tanks that did need to be pumped, but again, that was because of foreign matter introduced that killed the bacteria, or tree root systems clogging the feed lines to the drain field. Sometimes tanks WILL need to be pumped, but in my experience, it is because of misuse or overuse/undersizing.
I'm not going to be dragged into a debate looking for online info to back me up. If you want to believe everything you read on the internet, be my guest, but I've found that usable, real-world knowledge is not always based somewhere in cyberspace in the form of 1's and 0's.
The people who've been around long enough to know the real answer to your question are generally not the people who give a damn about the internet anyways.
In short, I've answered your query to the best of my knowledge, and in good faith. Sorry if that's not good enough.
Just FYI, if you're going to send PM's to bait someone, don't be so childish as to not receive them in return. Have a nice day.
