Does my system need to be pumped out?

Like an ordinary septic tank, sludge must be removed from your system periodically (such as once every two - four years).  Your service provider should provide guidance for you on this and if necessary will help to arrange for a septic tank pumping company to provide this service.  Pump-out frequency depends on waste stream strength and use; please consult with your service provider to help determine the frequency that is best for you.  Also, please note:  use of a garbage disposal may increase pump-out frequency.
