With a properly working system, and some of the above mentioned precautions system may never need pumped. Lot of people that have bought property never even know where the system is !!!!!!
The guy who installed my concrete septic tank when we rebuilt the system said the same thing. His mother has lived on a ranch and the septic system has never been pumped since it was installed in 1990. We didn't know where ours was when we bought the farm in 1999 but found it when we hit it with a plow.
