I think a lot of that has to do with the size of the system. My house is 2800 sq ft and it is just the wife and I. We also don't have to worry about the ground freezing. In the 10 years we have owned it, we have yet to need a pump out. My understanding, which may be wrong, is the bacteria breaks down the solids, and the liquids go out to the leech fields where they disappear. If 20 people lived here, it would need pumping. Am I understanding it correctly?
Here in Massachusetts we have two compartment 1500 gallon tank. The first compartment is where everything breaks down to a liquid and transfers to the second compartment. Whatever doesn't break down is sludge in the first compartment and a sediment in the second compartment. Overtime that sludge builds up, and if it builds to much it'll end up in the field and usually if it makes it to the field, it fails. It's probably not an instant failure but a slow death to the field... That's my take on it, we only install them, not maintain them.
