SEPTIC TANK AND SEWAGE TREATMENT PLANT EMPTYING
As a general rule, you should only need to empty your septic tank once every three to five years. That being said, the actual frequency will vary depending on your usage and how many people are living in your home. For larger households, your tank may need to be emptied more frequently. If you have a sewage treatment plant on your property you should ideally have it emptied once a year however this depends on how many people live at the property.
