Septic install

CenterLine construction is building our septic system.

They started by knocking down trees. Stumps make a rough fence along the road. Tops make a brush pile. Trunks will become lumber. I need to hire someone with a mill - there's a lot of lumber there!

Then they had the septic designer come out and look at the site. They talked about some technical details that were largely over my head, and then some tweaks to the layout of the drain field, which was not over my head. We rotated it about 80 degrees to follow the existing contours better.

On day 3 they started digging and filling the trenches.


There are 6 trenches, spaced 6' on center, each 50' long. Trenches are excavated to 4', then backfilled with sand (ASTM 33, if you must know). Here you can see Jeff working the sand:
