Any time you dig up your yard there will be settling. The important part is having the soil compacted and generally the contractor will use pea stone because it drains well, makes leveling the tanks easy and offers good support. It's more about the connecting lines than the tanks.

With out a dosing tank the wastewater flows from the septic tank into the leach field by gravity. With a dosing tank the wastewater flows from the septic tank to the dosing tank by gravity but from the dosing tank into the leach field by a pump in the dosing tank that has a water level sensor. This forces the wastewater into the leach field thus forcing the entire field to be filled, thus longer leach field life. To the best of my knowledge they are mandatory in most codes? They also come with a delightful alarm that will wake the dead if the system malfunctions.

See above diagram "Clean out plug" in a residential system there will be four of them. Common to see four PVC pipes sticking up in the yards but I trim mine so I can mow over them with no hand trimming. Not good to run over them directly with the mower as they can break the leach field at the connection.

I have my own composter. The compost is great to have around and it's easy and not expensive.

Not sure what you are referring to?

Maybe but I see no reason to have a sewage connection and a well. Generally the billing is related to how much water you use as they have a meter on that system.
