Yes, however if you're digging down to the lids you may as well have
it pumped anyway. How frequently it needs to be pumped is highly
variable based on what you let go into the system (kitchen disposer,
"flushables", etc.). A properly sized system that is only fed
digestible waste and sufficient water may never need to be pumped.

excellent advice

True.

But in the real world a certain amount of "indigestable solids" end up in
the system. For example, if your washing machine connects to your regular
septic system. the in-organic "dirt" on your clothing will end up on the
bottom of your tank. Maybe in a perfect world that would not go into your
septic system but ...

Pumping cost, typicaly, are less than $300. Compare that to your typical
city water bills (which are mostly for sewage treatment).

That's why most folks living on the "edge" of town only get connected to the
city system when they are forced to.
