Septic Tank Design

Aw, am I glad you're here today Guess what I discovered

I found a septic system that's being installed And you know what? They haven't covered it over with dirt yet The inspector is coming tomorrow, so it's a great opportunity for me to show you the basic components of a septic system The septic system consists of the septic tank, the distribution box, and the leach field This is the actual septic tank

It's a precast concrete structure that a crane actually lifts into position, and this particular one is probably 750 to maybe 1,000 gallon capacity And what happens – the waste water right out of the house comes directly into this tank It's got these lids that allow you to inspect the inside of the tank, and they also serve a very important purpose Every three or four years, you need to have a company come that actually puts a pipe down in here, and they pump out all of the solids that collect inside the septic tank This is the distribution box

What is does is the waste water from the septic tank comes through this pipe, goes into this little box, and it goes out to the leach field through these four different pipes This is the leach field, and it looks a little weird because of all this concrete It's not really a normal one Check out what's behind me – that roadway Well, you know what? This leach field is going to be underneath the road that leads to the house that's under construction

What happens in the leach field is that the water comes through that distribution box It goes out into those four pipes and feeds into this leach field The leach field consists of about a foot thick layer of sand, and the waste water percolates down through that sand It gets cleansed of all the bacteria and pathogens, and then it can flow back into the water table It's that simple

That's how septic systems work I'm Tim Carter for askthebuildercom If you want to discover more home improvement tips, go to askthebuildercom

I am going to give really special thanks to Rick Brue and Josh McNeil for allowing me to tape this septic system
