Around here we have septic systems and then septic systems. You will find this in most of rural America. Many homes had a leach pipe run out back and after about 20 years they would plug and they would ditch a new one a few feet over and start new. Cost about 500 bucks. Now they have rules and perk testing and regulations and a mound system costs about 10 grand. People just cant afford it a lot of the time and we have this one guy doing the midnight special they call it. He is in and out in the middle of the night and takes about 3 hours max. Everyone looks the other way and to be honest they seem to work just fine. I doubt you could get away with that on the left coast. my point is be ready for a different culture.
