So I guess when you get a septic system you need a drainfield too. City girl learning all these new, fancy terms ;) Anyway - I think what your looking at is all the gravel that had to be put down to cover the pipes to and in the drainfield. The last picture is the house with all the electrical line heading into the house. That made it in Tuesday night and I guess there are outlets and all that jazz as of last night! Electrician Beau has been hard at work the last few nights...beating out the heat with the big fan he tells me.
