How about a septic system? Synthetic fibers don't break down in a

Non-soluble material in a septic tank either floats or sinks. The tank is
designed to draw from the liquids in the center of the tank. Any fiber would get
pumped out of the tank with all the sludge during the normal cleanout every
couple of years.

Having lived and worked for several decades in an area that did not
have sewers, I can assure you that your theory is perfect...in theory.
Some people go years without having the things pumped out, and others
are on a maintenance schedule. Some households do a few washer loads a
week, others do several a day.

As in everything else construction - everything in life, really -
preventative maintenance is far cheaper and easier. Changing a lint
trap at the washer outlet takes two minutes and costs a buck. So for
half an hour's work and a twenty dollar bill you're postponing pumping.
How much does it cost in your area to pump out a tank?
