Septic drain field replacement cost.
Septic tank leach field size.
The soil should.
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.
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.
A buried watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater.
The size necessary for your drain field will depend on a few factors.
1 inch in 3 minutes sandy soil.
An important soil characteristic the percolation rate measures how long it takes water to drop one inch in a saturated hole dug in soil.
An improperly designed drain field will do nothing but cause huge problems with the entire system.
1 inch in 48 minutes clay soil.
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.
When you design your drain field there are a few things to keep in mind.
A septic drain field is a vital part of any septic system.
The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal.

When you install or repair an existing septic system the absorption field size should always be one of the more important design elements.
