Generally speaking, for a 1500 gallon septic tank with a properly working leach field, it is recommended to have the system pumped out every 3 to 5 years. This can vary depending on factors such as:

  • The size of your household
  • Do you use a garbage disposal?
  • Does your laundry water go through your system?
  • Is there adequate bacteria in your system to aid in the digestion of organic solids?
  • Do you want your system to last and work effectively as long as possible?
