Completed the installation of the septic system. Fortunately Williamson County concluded that my soil would support a gravity fed anaerobic system (without pumps or chemicals). I’m surprised at how big the drain field needed to be. It’s actually larger than the one we had in Santa Fe, and that was for 3 bathrooms and really heavy clay soil.
Bobby Anderson was hired to install the 750 gal tank and the 75’x20′ drain field. The design was done by Jason Clark. The whole thing cost $8,600, with $600 of that going to the county for permits/inspection. Fortunately, that’s the only thing the county regulates.
