Installed the septic today with the help of another neighbor. He does tractor work so while he dug the hole, I ran the pipe. It was a long 7 hours but it was worth it doing it myself with a great neighbor/ friend. I ordered a big tank with infiltrators. Total cost to install the septic was $1445.46. Not bad. If I paid someone to do it, it would have cost me $3600 and the tank would not have been as nice.
