how do i build a residential box trough septic system?

Question

I need to know more specifics abouth the trough itself. i.e. lenght, size, depth etc

Answer 1

You trough is based on the number of bedrooms that you have in the house. You can get the sizes recommended in your location by visiting their website. try the Department of Natural Resources in your area. They are responsible for septic systems to ensure the "products" in the system don't seep into the earth. Good Luck

Answer 2

Got to the local Health Dept, they will tell you, and it some places do it yourself is no longer allowed.
