How Often Should a Septic Tank Be Pumped?


View of a septic tank

If you're a new homeowner with a septic tank in Sudbury, you're probably wondering how long it takes to get full. You certainly don't want it overflowing into your garden or backing up into your house.


But did you know there are specific rules you need to follow regarding its discharge? Read on to find out all the variables.


Consider the Size


The first factor governing how often to pump your septic tank is the size—or volume—of the tank. This determines how much sewerage it can hold. Generally, the bigger your tank, the less often you'll need to get it pumped. But this could change depending on factors like family size and the number of inputs. (More on that soon!)


Sludge and Scum Levels


Septic tanks use a few natural processes to work correctly.


One is gravity, which separates the solids (also known as sludge) from the effluent (the watery component of sewage). As a result, the solids sink to the bottom of the tank, the effluent sits in the middle of the tank, and the grease (the scum) floats on top.


If the levels get out of balance, your system can get backed up, resulting in dangerous flooding on—or worse, in—your property.


A sewer service professional can check your tank and let you know if it's in balance or not.


How Big Are Your Home and Family?


One of the most helpful septic tank tips is knowing how the size of your tank corresponds to the size of your home and family.


For example, if you have a large family in a large home, you'll need a large tank, and you can pump that tank less often. On the other hand, if you don't have a large tank, you'll need to pump your tank frequently.


Other household activities that can influence pumping frequency include:


  • If you often flush non-septic-friendly items

  • How frequently you have guests staying over

  • Whether you operate a business from your home

  • Whether there's any machinery connected to your septic system

  • How frequently you run the washing machine
