*Stretch a level line from the building at the point where the sewer will leave it to the point where the sewer will connect with the main or septic tank.
*Attach this line to a stake at both ends to hold it above ground; use a spirit level to get it horizontal.
*Lower the end of the line at the main or septic tank the necessary distance to get the proper pitch. For a horizontal run of 100 meters, lower the line 2 meters; for a run of 50 meters, lower it 1 meter; for 25 meters, lower it 0.5 meter; and so on.
*Cut a measuring stick to the length of the distance from the level line to the bottom of the drain where it leaves the building, and use this to guide the depth of the trench from the level line throughout its course.
