I had a visit from the septic company and the county health administrator. He approved a terralift and jetting and gave me a year to rehab the field or he will require replacement of the system. My plans show a leachfield but I actually have a trench system in place. They will install risers over the tank and dig up the distro box, which I will prob put a riser on if they won't. They will jet and apply an oxygenation solution to the trenches. They will install an effluent filter, and terralift the soil. Depending on the results i will decide if septic seep or anything else would need applied later. If this doesn't work, my entire back yard, irrigation system, and driveway are toast, and I'm close to 30k poorer. Haven't got the estimates yet for the repair treatment but I will let you know. Thanks again for your advice!
