Trace the plumbing drain lines to the septic tank which is usually installed 10 to 20 feet from the home s exterior.
In a conventional gravity system the pipe from the house to the septic tank and the outlet pipe from the tank to the distribution box or leach field should both slope downward with a minimum slope of 1 4 inch per foot.
Maximum length of any leach line is 100 feet.
A buried watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater.
If more than 100 feet is required then a distribution box with multiple lines will be needed.

A septic tank needs to be adequately sized so that the retention time the length of time that wastewater effluent remains in the tank before flowing to the drain field is sufficient enough to allow heavier solid particulates to settle to the bottom as sludge and lighter solids such as fats and oils to float up to the top of the tank.
Check the natural slope of the land to locate the leach field.
