Drain field replacement can cost anywhere from 2 000 to 10 000. While all septic tank drain fields require regular inspection you can save a lot of money by digging one yourself. The first sign of a problem with drain field is often a swampy area in the yard or an odor of sewage on the property. There should be at least 100 feet of drain field for a 1 000 gallon septic tank.

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. Step 1 choose your site. You will want to choose a site that is away from the house but close to the tank. See your local health requirements for the size of embedment needed and the size of gravel.

To prevent erosion make a rock bed around the end of the tube. Place in most jurisdictions inch and a half washed drain rock from a nearby gravel pit around the pipe. This can be accomplished by making four trenches 25 feet long or two trenches 50 feet long. Each drain field trench should be at least 3 to 4 feet wide and 3 to 4 feet deep.

The drain or leach field is the section of the septic system that transports the waste water back to the soil.
