I think if you pump it out on a regular basis and don't allow stuff that
doesn't break down easily to get flushed down the drain you are doing
the best you can.

I have heard of drain field failures due to soil that can no longer
absorb after 20 - 30 years of use. I've seen metal tank tops fail. I've
heard of poor quality concrete tanks failing after 20 - 30 years. Some
areas now allow "plastic" tanks.

I have neighbors that have never pumped their septic system out in 20
years.
They should have sticker shock when that puppy implodes.
