2.Tank & Family Size
The frequency with which you need to schedule a septic tank pumping depends on the tank size, the family size, and whether you use a garbage disposal unit or not. Typically, a 1,500-gallon tank that is used by a family of four needs to be pumped after four years. However, if the family also uses a garbage disposal the amount of solids in the waste water doubles, so the tank needs to be pumped every two years. On the other hand a family of four with a smaller septic tank or a family of two with a 1,500 gallon tank will need to change the frequency of pumping. Home owners can keep a record of when they pumped the septic tanks and the amount of sludge removed to better calculate when they next need to schedule a pumping of the septic tank.
