* Most aerobic systems have trash tanks smaller than 500 gallons
NOTE: More frequent pumping is needed if you use a garbage disposal or thick multi-ply toilet papers.
Septic tanks don't fail immediately if they are not pumped. They will, however, continue to fill with solids and may back up sewage in the house, or accelerate failure of your components downstream.
It is much cheaper to maintain your system than repair (or replace) it.
-- To replace just the septic field could cost thousands of dollars or more.
-- To replace your septic system often costs tens of thousands of dollars.
