This fall, we have big construction project at our home. We need to replace our 36 years old septic system. It lasted about 2 weeks and the kids enjoyed watching the big machines working. It was amazing that a 2-person crew could dig up so much soil and level the ground in a short time. One surprise we found out was that the original septic system had no sand or minimal gravels for drainage. The contractor said he had never seen anything like this before. He couldn't understand how the system would work for 36 years. Well, we don't have a single sewage backup for 6 years and I do thank God for keeping the system working.

Now we are waiting for the building permit for our addition. My hope is that the new space would give us some extra room for homeschooling and home business. And Kay can have her cold cellar to store the grains. We pray that God would give us some decent weather before Christmas to allow the foundation to be laid properly.

This is the new septic tank.  It has 2 covers for access with filters that I need to clean once a year.
Since the elevation of our front lawn does not meet requirement, we also need a pump chamber with a submersible pump installed. Any grey water from the septic tank would flow into this chamber and pump out to the tile bed.
As you can see, we have to dig down to almost 5 feet and bring in clean sand.  What a big project!
