Head to https://www.betterhelp.com/atticus to get 10% off your first month with our sponsor, BetterHelp. Therapy can be a meaningful space to reflect, grow, and create positive change in your life.
This week, we tried to dig the sewer trench from our house to the septic tank โ and quickly found out that our rocky mountain lot was not going to make it easy.
While the drywall crew was inside hanging sheets and turning the interior into actual rooms, we were outside trying to get the utilities sorted before the next big step on the build. We had to clear the future porch slab area, add drainage for one of the lowest spots around the house, connect the water line, and run the sewer line across the yard.
The sewer trench ended up being the main challenge. We hit hard rock, ran into the wrong fittings, had to sleeve part of the pipe for vehicle traffic, and spent a lot of time checking and re-checking the fall so the line would drain properly.
By the end of the week, the house had drywall, water, and sewer โ which felt like a pretty solid bit of progress.
Huge thanks to the crew who helped make this happen โ links to everyone involved below.
