Step 1: Do Your Investigation
Contact your local district office and health authority to determine whether a permit is necessary to build a septic field line. Also, determine whether the health department should inspect the drain field while it is being created or after it is completed. In most circumstances, permission will be necessary, as well as an examination.
Step 3: Assess the morphology of the soil
For areas where soil properties signal a possible contamination risk to groundwater, soil geometry analyses get suggested. In the United States, these examinations may only get carried out by people who the Board of Health has authorized.
Step 4: Discover Underground Infrastructure
Contact a utility-finding firm before digging to ensure you don’t damage any underground power wires. Rit dye or flags will get used to designate the ground over any lines. You may be accountable for the expense of restoring the lines, including materials and labor if you wouldn’t have the cables identified and cut one or all of them.
Step 5: Dig Sink Field Ditches
Every drain-field trench must be 3 to 4 feet broad and 3 to 4 feet underground at the very least. For a 1,000-gallon septic tank, there must be at least 100 feet of a downspout. This may get achieved by digging four 25-foot trenches or two 50-foot ditches.
Step 6: Fill in the gaps with gravel and punctured tubing
Place a heavy layer of pebbles throughout the full length of the hole, at least 1 foot thick. A half-foot of rocks would be preferable. Place punctured tubing on top of the stones in the hole. Attach the tube to the septic tank outlet using a clip.
Step 7: Increase the Gravel
On top of the tubing, add another half-inch of pebbles and some along the pipe’s edges. Wrap the gravel with a septic cloth to stop dirt and grime from entering the stones.
Step 8: Place the Linen
Spread your linen over the tube and gravel after they’re in place. Any form of textile that breathes may get used. Its purpose is to prevent dirt and grit from clogging the soil spillway.

The soil will filter out the harmful bacteria and reintroduce it back to the water table.
What is a perforated pipe?
Perforated pipes are pipes that have holes close to the bottom.
