In general, a septic tank should be inspected every 1 to 3 years and pumped every 3 to 5 years. The frequency of pumping the septic tank depends on the tank size, number of people in the household, habits of water use as well as the amount of solids accumulated in the tank. Some alternative systems that are more complex may require more frequent inspection or pumping. If you are unsure, ask your local septic system professional. A septic tank effluent filter may also require frequent maintenance and should be included in the inspection and maintenance activities. It is important to save your system’s yearly schedule or maintenance records.
