Over time leach fields can build up sludge or tree roots can grow into them to form clogs which causes your septic tank to back up or leak into your yard.
A septic tank needs to be adequately sized so that the retention time the length of time that wastewater effluent remains in the tank before flowing to the drain field is sufficient enough to allow heavier solid particulates to settle to the bottom as sludge and lighter solids such as fats and oils to float up to the top of the tank.
If more than 100 feet is required then a distribution box with multiple lines will be.
