Dave- I made my own septic tank using an 1100 liter tinaco which I embedded in the ground. I used a panel from a 55 gallon poly-barrel as a baffle in the tank to improve separation of solids from effluent. After the outlet I put in a cleanout and manifolded that to two four inch leech lines, each 54 feet long. The leach lines are embedded in a gravel field about five feet wide and four feet thick. The top of the gravel bed is protected with engineering cloth before backfilling. I had to make the perf pipe, because it is not available locally, by drilling holes every four inches along the center line of the pipe. Perf pipes are installed with a fall of about one-eighth inch per foot. I tested the percolation with a garden hose before I backfilled and all the flow leached out in less than twenty feet of pipe. My bathroom floor is installed over the tank with an access cover, should I ever need to have the tank pumped out. And the cleanout is outside, in case I ever need to burn out the leach lines with caustic soda. Mark
