Septic tank leach field size.
There are many factors involved in sizing an absorption field including setbacks to wells and property lines soil and other geological conditions as well as overall site suitability and accessibility.
Septic drain or leach field replacement will cost between 3 500 to 11 000 with most homeowners paying a total of 7 000 on average.
An important soil characteristic the percolation rate measures how long it takes water to drop one inch in a saturated hole dug in soil.

Design guide for septic drainfields.
A buried watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater.
A septic drain field is a vital part of any septic system.
If it takes less than 5 minutes for the water to drop 1 inch in a saturated hole the effluent will move too rapidly to be treated properly such as in sandy.
The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal.
Heavy solids settle to the bottom of the tank while greases and lighter solids float to the top.
An improperly designed drain field will do nothing but cause huge problems with the entire system.
When you design your drain field there are a few things to keep in mind.
Step 1 determine the size.
When you install or repair an existing septic system the absorption field size should always be one of the more important design elements.
