F’ing Septic Tanks

Had that problem with my Dad's septic system a few years back, come to find out when the cement truck came and poured his new front porch, it collapsed the lateral lines. He had new lateral lines installed and it fixed the problem. I also saw a friend's system once ruined were cigarette butts had been flushed down the toilet, was told they wont break down and stopped up the holes in the lateral lines. There are alot of pond systems up here were I live due to the poor perk of the ground, folks put cattails and lillies in them as a landscape, but I don't like the idea, I also know a few folk's that have 2 tanks, problem here is slate rock instead of clay though.
