The overflow water from the liquid side of the septic. I guess black and grey water, everything from the house anyways.
The sump having water in it is something I have just noticed since installing the tile across the back of the house, I am wondering if it is to much water for the system to handle like you mentioned
So the “overflow” from the septic system is the normal Black Water. That is tied into your leach lines. The septic leach field isn’t designed to handle storm water. Leach fields are designed to handle a few hundred gallons a day. Storm Water could be that much an hour.
You will need to separate the storm water and the septic leach field. If it’s too late in the year to add a storm water leach field just use your little sump pump to pump the storm water to the low side of the property.
Storm tiles/drain tiles (another word that may be a misused word) are typically at the footing depth- irregardless of depth. If it’s a curtain drain or trench drain then those are typically 1-3’ unless an engineer has designed something to catch known subterranean water.
