Septic Leach Line.
Leach line material consists of plastic shells with a pipe going along the top of the form that allows leachate to drip into the trench.
The first operation is to cut open a trench using a back hoe to a depth of 6 ft -7 ft or until a sand layer is reached.
Install the leach line in the bottom of the trench.
Add section together until the full length of leach line is connected.
After installing each section, back fill with sand. The pipe at the end is connected to the pipe from the leach tank.
Fill in the trench and connect the leach supply line.
Fill the land level to 6-10 inches above grade to prevent flood irrigation from entering soil above leach line.
