Prices for septic systems seem to be all over the place. When I first joined TBN, there were conversations about septic systems, I might have started one myself, and the TBNers from Texas were saying that aerobic systems were about $5K. Back then, in my area, a LPP system were going for $15K and aerobic was around $30K! :shocked::shocked::shocked: I could see no justification for those prices other than that was what the market was bearing. :confused3: At the time, I could install my own system and at those prices I would have. The system had to be designed by an engineer so all I had to do was follow the design. Not that hard and for the quoted prices I figured I could fail multiple inspections before passing and still save a bunch of money.
I have heard the prices have come down a bit but $11K for a normal sized system would be very cheap here.
Good Luck,
Dan
