A septic tank works by having the sewer come from your house into your septic tank, which separates the solids from the liquids. Your septic tank will allow the fluid to pass into drainage fields through a perforated pipe, where it will be absorbed into the earth. Experts recommend that the average septic tank requires a space about 10 ft x 10 ft to install. The drain field where the wastewater will flow into should be about 30 ft by 50 ft, or even larger, with a secondary area the same size available in case the first drain field fails. It is recommended that have at least 4 ft of good soil from the surface to the water table, and at least 2 ft of separation from the bottom of the trench holding the septic tank to the water table. |
