How Often Should You Have Your Septic System Pumped Out?

Your septic system treats wastewater by temporarily holding it in tank where heavy solids and scum are allowed to separate from the water over time. During this process, the partially-treated wastewater flows from the septic tank to a distribution box, where it is routed to a network of drain field trenches for secondary treatment in a Soil Absorption System (SAS). This two-stage system gradually removes toxins from the wastewater so that it can be safely returned to the ground.

Meanwhile, the remaining scum and solid waste products settle at the bottom of the septic storage tank where they are decomposed by naturally-occurring bacteria. Over a period of weeks and months, these solids form a layer of accumulated sludge in the septic tank. Sooner or later, this sludge must be pumped out of the tank to prevent groundwater contamination and plumbing backups.

But how often does your septic tank need to be pumped?

As a general rule of thumb, you should have your tank pumped out at least once every three years. If you have a garbage disposal in your kitchen, however, you should have your tank pumped out every year instead. You don’t want to wait to have your tank pumped until it’s filled to capacity. When it comes to septic maintenance, it’s always best to err on the side of caution.

If you suspect your septic tank might need to be pumped out soon, you should be sure to make an appointment before the winter arrives. Once the ground freezes and snow begins to fall, it becomes much more difficult to treat septic issues. The last thing you want is to wind up with a septic system backup in the middle of January.
