How utility conduits will be connected to the house in the future.
Please see the DJI_0005_Utility_Routes image This shows the aerial view of the entire property. The current house, and the garage under construction. The RED arrow starts at the suggested beginning burial point for the 200 amp electrical WIRE which will be connected to only 100amps at this time. The BLUE arrow shows where the other utilities (Sewer, natural gas, water, low voltage conduit) will connect to the house. Both arrow terminate in front of the garage foundation and will run through conduits into the future mechanical room.

Electrical service to garage
I have spoke to several electricians and they all scoffed at the idea of me upgrading my home service from 200 amp to 400 amp and running a 200 amp line directly to the garage. My thought was then each building would get 200 amp service. They stated convincingly that 100amp was plenty for the garage. And after hearing them explain I had to agree.
However! I did convince them that it was a good idea to run a 200 amp WIRE instead of a 100 amp wire from the house to the garage just in case I wanted to upgrade to 200 amp in the future. They also agreed it would be wise considering this future option to put a 200 amp breaker panel in the garage despite the 200 amp buried cable only being connected to 100 amps at the house.
The power comes into the house via a underground wire and up to a consumers power meter on the exterior of the house on the south west corner of the house. It then goes into the basement and terminates in a 200 amp breaker panel in one the west corner of the south wall.
Therefore all contractors felt that they would need to dig a separate trench for the power line as all the other utility lines
You can see this fact in the image provided that clearly shows the RED arrow path for the electric service which is separate from the BLUE arrow path for the other utilities.
Sewer/Natural Gas/Water/Low voltage
See @“content/50-Build/Utilities & Conduits.md” document.
Sewer will be 3” pipe buried at the appropriate depth and angled towards the house where it will connect to the main sewer stack.
Natural gas will use a flexible PE Polyethylene Pipe from the house to the garage. I think bigger is better so at least a 1” pipe.
Water will be direct burial ASTM F2023 standard PEX to the house. the house has a 3/4” pipe from the city, so max would be 3/4” to the garage.
Low Voltage. This one is up for debate. I would like to install some sort of 2” pvc conduit from the house to the garage with pull cable(s) so I can future-proof any additional lines that I would like to run from one building to the other. Assuming they are low voltage like network, fiber, phone, coax, etc…
