Drain Field Installation

The field should be at least 10 feet away from your edible garden and any water such as a lake river or well.

Drain field installation.

The drain or leach field is the section of the septic system that transports the waste water back to the soil. Where the tube passes by the downspout from the gutter we installed a y fitting and drained the roof water from the gutter system directly into the main drainage line. This can be accomplished by making four trenches 25 feet long or two trenches 50 feet long. Screw a drain cover over the end of the tubing as it approaches daylight to keep critters out.

There should be at least 100 feet of drain field for a 1 000 gallon septic tank. To prevent erosion make a rock bed around the end of the tube. Drain field replacement can cost anywhere from 2 000 to 10 000. Each drain field trench should be at least 3 to 4 feet wide and 3 to 4 feet deep.

Step 1 choose your site. This is required to hold the pipe steady. The perforated pipe in a gravity drain field has no slope end to end and has capped ends. See your local health requirements for the size of embedment needed and the size of gravel.

While all septic tank drain fields require regular inspection you can save a lot of money by digging one yourself.
