What is a septic drain field?
Also called a drain field, the main job of the drain field is to remove contaminants like harmful coliform bacteria from septic tank effluent via perforated pipes or corrugated drainage pipe called leach lines that soaks the surrounding soil. Using the soil bacteria to naturally remove nasties before they reach the water table or groundwater.
How deep does a septic leach field need to be?

How long will septic drain field last?
It's important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible. The biggest risk is exposing the concrete to acidic substances.
How far should a septic tank be from the house?
Requirements vary from one area to another, but the normal minimum distance from the house is 10 feet.

Can a septic drain field be cleaned?
It is often possible to clean and renew a clogged septic leach field instead of replacing the drain field lines. Septic field lines can fail to drain when heavy solids accumulate and block perforations in the lines. This is commonly seen in septic systems that are more than 20 years old.
How do you unclog a leach field?
If you suspect one of the leach field pipes has a clog, the easiest way to clean it is with a pressurized sewer jetter. If the clog doesn't clear with a jetter, there may be tree roots that you can cut with a mechanical auger.
Can a neighbor drain water on my property Michigan?

A high quality septic drainfield or leach bed design includes inspection ports or pipes that permit inspection of the condition of the field . Vertical pipes are placed, usually at the end of each drainfield trench or section or at critical or suspect areas near the drainfield to permit monitoring of liquid levels in the drainfield trenches.
What is a septic tank?
A septic tank is a large concrete box, which will hold thousands of gallons of liquid. In use, this tanks slowly fills, and all the materials which enter the tank are slowly “digested”. Ordinarily, a waxy layer builds up, over the surface of the material in the tank.
How often should a septic tank be pumped out?
Some people have their septic tank pumped out regularly, perhaps once every three or four or five years. This permits the leaching field to “rest” for a while, until the fluid level in the tank again reaches the overflow level, and the leaching field is again called upon to disperse the outflowing fluid.
Why is my septic tank overflowing?
The only reason a septic tank would be overflowing is the drain field is plugged, blocked, collapsed or otherwise not working properly. Older style septic tanks used a gravity feed system that moved the fluid from the tank to a distribution box which then fed to the multiple field drain lines. Some modern systems have a pump that forces these fluids out and this pump could fail. These systems don’t need the tank higher than the field and could flood. Often modern systems have multiple tanks; one that serves the same function as the old system and one that has an aerator in it to perform additi
How long can a septic system function without attention?
If the usage is low, and if the absorbency of the leaching field is high, then the septic system can function without attention for scores of years.

In the septic tank, low-density stuff (oil, floaty poops) rise and are held back by a baffle while dense things sink to the bottom and are retained by a weir.
What is the term for the area where liquids soak into the soil?
That outflowing material gets spread out through various side pipes, into a “leaching field”. The liquids soak into the leaching material, which is often a layer of sand or of crushed rock. Or it can be merely the native earth. Of course, the leaching field is some distance below the overlaying ground level, sufficient that odors do not percolate upward through the earth.

Look at the naturally sloping land and you will be able to find the leach field.
How Do Septic Tank Field Lines Work?
The septic tank drainfield works in a simple process. The pipe gets waste from the septic tank. The perforated pipe then distributes this among the aggregate. It then trickles slowly through the aggregate. Next, the soil receives this effluent. Finally, in the last process, the soil filters out all harmful bacteria which is present in the waste. It is then returned to the water table.

Knowing the location of the septic tank is necessary because you will have professionals coming for inspection and maintenance. You will not want to keep looking for the drainfield in their presence.
How does a drain field work?
A drain field is designed in a way to let the liquid from the tank get absorbed in the ground. The solids usually dissolve, and they break down. Liquids tend to flow from the tank and through pipes to the drain field. Next, they exit and move into the ground. They move through holes in pipe. However, with time, this leach field might be clogged or damaged. This can happen because of buildup of material.
Why should you be aware of the location of septic tank field lines?
