My Aquifer > Septic System Basics > Where should you put your septic system?
Septic tanks usually have to be at least 5 feet from the building and 5 to 10 feet from the property line.
They usually need to be at least 50 feet from wells, lakes, rivers, streams, springs or reservoirs.
Some areas call for a 10 foot clearance from large trees.
TAKE A LOOK at a tile bed location diagram.
ALSO LOOK AT a well/septic planning diagram.
