It will cost about 30 per linear foot to dig up the old leach field and 9 to 12 per linear foot to lay the new filtration materials or leach field.
Septic tank leach field size.
When you install or repair an existing septic system the absorption field size should always be one of the more important design elements.
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.

Design guide for septic drainfields.
A drain field will flood.
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.
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 improperly designed drain field will do nothing but cause huge problems with the entire system.
Heavy solids settle to the bottom of the tank while greases and lighter solids float to the top.
When you design your drain field there are a few things to keep in mind.
The size necessary for your drain field will depend on a few factors.
A septic tank needs to be adequately sized so that the retention time the length of time that wastewater effluent remains in the tank before flowing to the drain field is sufficient enough to allow heavier solid particulates to settle to the bottom as sludge and lighter solids such as fats and oils to float up to the top of the tank.
Step 1 determine the size.
An important soil characteristic the percolation rate measures how long it takes water to drop one inch in a saturated hole dug in soil.

The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal.
