Homeowners looking to save some money on costly home repairs might need to pay extra attention to their septic tank systems.
Case in point: you will spend about $469 on septic tank pumping costs. Meanwhile, if you leave it overlooked, a total septic system replacement can cost you a whopping $5,750 to $11,500. That's thousands in potential savings we're talking about. Residential septic tanks need to be regularly inspected and pumped to avoid malfunctions.
The United States Environmental Protection Agency (EPA) strongly recommends septic tank inspection once every two to three years, with mechanical pumping every three to five years to empty the tank. However, systems that have heavy use can benefit from annual pumping.
What is Septic Tank Pumping?
Simply put, septic pumping removes all the sludge in the bottom of a tank. It is ideally done before the excessive sludge build-up already blocks the outlet pipe– where the liquid typically passes through into the drain field. If your septic system sees heavy usage, a septic service professional will advise you to pump your tanks when the floating scum layer (between the sludge and water) is anywhere near six inches from the outlet pipe.
At this point, you might be wondering, "how much does it cost to pump a septic tank?" or "how much does septic tank pumping cost?" Fortunately, you won't have to break the bank over septic tank pump-out costs compared to repairs.

Factors Affecting Septic Tank Pumping Cost
Several factors increase the cost of having a septic tank pumped– two of them being the size and usage. Small tanks and tanks that are used frequently will need regular pumping. Let's discuss the other influential factors below so you can prepare your budget accordingly.
Simply put, the size of your septic tank will determine the total cost of cleaning or pumping. On average, septic tank pump-out costs approximately $0.35 per gallon, with standard tanks ranging between 600 and 2,000 gallons in size. A 600-gallon septic tank will cost you $210 on average, while a 2,000 gallon-sized septic tank will run for $700 or more.
Accordingly, larger septic tanks can go for a while between cleanings, while smaller ones will need to be pumped more often to ensure optimal performance. Here's a quick overview of septic tank pumping prices based on their size:
Septic Tank Size (Gallons)
600 - 750 Gallons
$210 - $345

1,250 - 1,500 Gallons
$316 - $575
1,750 - 2,000+ Gallons

Another factor that may influence the price of septic tank pumping is the location of your property. Depending on where you live, you can ask around for three to five quotes from septic tank companies to know the average service rate in your location.

If your septic tank system sees heavy usage, it only means you will need to pump it more frequently. It’s that simple.
In particular, if you regularly use a lot of water daily, shove excess food down the garbage disposal, and invite a bunch of guests over for events– these are some signs you need to pump your tank often.
We already discussed how more usage equates to a higher pumping frequency on your end. Now, the difference between spending $469 every two years from three to five years. It all boils down to how you manage your septic tank and leach field.
Fortunately, there are things you can follow to decrease your septic tank pumping frequency:
Emptying a Tank
Septic tank pumping doesn’t typically require you to do a complete drain out. You will only need to remove most of the sludge, which costs around $316 to $667 on average.
Unless you are moving, removing, or replacing your septic system, you do not need to drain the tank completely.
Septic Tank Cleaning
After the tank pumping process, it's always a good idea to give your septic tank a thorough cleaning. It will cost you somewhere between $115 and $920. If you're dealing with large commercial systems, expect to shell out some more on cleaning expenses.
Some homeowners tend to mix up septic tank pumping with cleaning. Let's shed light on the matter; pumping gets rid of the effluent. Meanwhile, cleaning removes any debris from the filters, pipes, and pumps.
