Tank is a filter. It keeps solids out of the field. Problems mean it is too late. Pumping out a tank is near zero money. Digging up, removing, and then installing a new field can be as much as a years income.

You don't see problems until long after a field must be replaced. Cheaper is to pump out the tank.
