Our house drainage system is a bit complicated.
There are two sewer drains that run out from two different places from the house, which then get to run into two septic tanks...thank you Cassia County. The only "fun" part? Renting the excavator.
Here you can see the smaller trenches running into where the two septic tanks would be placed.
The ground in the "pit" had to be completely level, and then the spot for the second tank had to be exactly 4.25" from the first. We were able to use a laser level to help us be that accurate. It felt a bit like being in a tomb down there as we were working!
You can see the two trenches running toward the tank area better in this photo.
It was nice to take a break and watch the tanks be delivered and carefully installed.
Each tank weighs 8000 pounds.
Carefully guiding the tank into place.
Here is the second tank, just below the first.
Once the tanks were in place, we had to dig the drainfield. This consists of 6 feet wide 5 feet deep trenches that will be filled with perforated pipe and gravel. We had to have a total drainfield of 150 feet.
We used the laser level to help us keep a consistent grade.
The drainfield will be in a big portion of our backyard. I hope it helps the lawn grow! :)
The kids have had fun playing in the trenches, and even got to use the equipment a bit. Once we complete the septic system, we'll be able to have the concrete poured, and get the remaining outside work finished up. Hooray for progress!
