From the web site below The frequency of pumping depends on several factors:<p>1. capacity of the septic tank 2. volume of wastewater (related to size of household) 3. amount of solids in wastewater (e.g. garbage disposals produce more solids)<p>We went 5 years until a large piece of machinery drove over it and tilted the whole tank. We redid the drainage field when we replaced the tank. Both sludge in the tank and a clogged drain field will back the system up.
