Preparing for the stem wall - step one: 6" chase under the wall for the 4" blackwater sewer line running from the house to the septic.
We decided go ahead and run the sewer line while we had it dug up. So we connected to the stub out from our septic tank and ran it under the stem wall through a 6" chase.
Notice the laser level used to measure the slope on the pipe. This is to be sure we maintain the required 1/8" per foot slope on the pipe. If the pipe slopes much more than 1/8" per foot, we will be too high to hook up with the clean out / rv hookup we ran under the back tire wall.
A clean out is required each time you have more than 45 degree bend. We had to make a 90 degree bend so we used two 45 degree turns and put a clean out in.
Chase is in place over the pipe where it will pass under the tire wall.
Ditch is filled and tamped. Dirt was layered in 4-6" layers and tamped until the pipe was covered and the ditch was level with the ground around it.
Good job on the pictures. The local health department made me expand my leach field to handle 750 gallons of wastewater a day - even though my well can only produce 350. When I asked why... They said for the "future". I said under my breath - If a hydrological event increases my well production that much - the last thing you will care about is my leach field. You low-landers will be more worried about building an ark.
