Replace Leach Bed: Septic System

[Paul Scott]

I have a 50 year old home with a septic just as old.
I need to replace the lateral lines and leachbead.
My questions are as follows:
How deep should I dig the trench for the lateral lines and fingers?
How much gravel should I use?
Should I use a screen around the flexible periforated pipe?
How many feet do I need with a 4 bedroom house.
I want to do this myself to save money.
Any suggestions will be greatly appreciated.
Thank you,
Paul

It would be impossible to give difinitive answers because the depth and length of the lines will vary from region to region depending upon such factors as average frost depth and type of soil conditions. Also, in some regions you must be a licensed septic system installer to perform any service on a septic tank or leach field.
