Septic tank pumping is an essential maintenance task to keep a wastewater system in order. But how much does it cost to pump a septic tank?

Septic tanks need to be pumped every two to three years to keep working properly. Done on time, the service costs a few hundred dollars. But left for decades, septic cleaning can turn into septic replacement and cost you $5,000 to $10,000.

Here are some important facts about septic tanks, including how they work.

Where the Waste Goes

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. Their capacity is based on the size of the home, and they are the ultimate destination for all of a house’s wastewater — from bathtubs, showers, sinks, toilets and washing machines.

Most tanks rely on gravity to work. Wastewater flows into the tank, which is buried in the ground outside the home, and water in turn is carried from the tank to a drainage field using sloped pipes.

How a Tank Works

When wastewater enters a septic tank, it naturally divides into three parts:

Solids sink to the bottom and form a sludge layer. Liquids stay in the middle and form a layer of mostly water. Oils and fat rise to the top and form a scum layer.

The liquid layer accounts for 90 percent of a tank’s capacity, meaning excess water use can affect the tank’s performance over time.

Ideally, water in a tank flows through in the course of several days while materials on the bottom are broken down by bacteria. Water is then carried through drain pipes to the drainage (or leach) field, where it is distributed into the soil. The size of the drainage field depends on the type of soil. Clay, for instance, holds a limited amount of water.

The sludge at a tank’s bottom requires periodic septic cleaning or pumping. Even the best bacteria can’t fully break down all organic material, meaning it will start to build up and take more of the tank’s space. If there’s not enough room for water, the sludge will start to back up into the leach field, a home’s pipes or may cause a tank failure.

Homeowners can clean out their septic tanks, but they will need to store the sludge for transport and safely dispose of it. Professional septic cleaners come with a tank truck that hooks up to the septic system and removes its contents, then transports it all safely off the property.

Average Septic Tank Pumping Cost

Angie’s List members who recently had septic tank cleaning performed reported paying an average of $270, with a general range of $245 to $295, not counting discounts many service providers offer to members.

Septic Tank Maintenance

There are several ways to keep cleaning costs lower and limit the chance of a broken tank:

  1. Create a diagram showing the home in relation to the tank, along with distances and depth.
  2. Knowing exactly where the tank is will let the homeowner tell the cleaner exactly where to dig and find the tank quickly in an emergency.
  3. Don’t park cars or build structures atop the tank, as this increases pressure and may cause a rupture.
  4. Don’t plant anything in the drainage field. Natural grass is the best choice.
  5. Watch what is put down the drain. Baby wipes, diapers and paper towels can clog pipes, while harsh chemicals may kill helpful sludge bacteria, resulting in a backup.

Going Pro

Call several contractors in the area for estimates, and check Angie’s List to find reputable providers. Ideally, look for a company that does tank maintenance in addition to septic pumping because they can to spot problems along with signs of wear and tear.

Read any agreement carefully. Where will they take the waste, and what will they do with it? While a low price or special deal may seem good upfront, fly-by-night companies may damage the tank when trying to drain it as quickly as possible.

To keep a septic tank in good working order, schedule cleanings every two to three years with a reputable provider.

    Thanks for telling me that a septic tank replacement can cost me from $5,000 up to $10,000. We certainly don’t have that amount and if we do, we don’t want to spend it just to replace a faulty system. It might be really better if we were to just invest in the maintenance of our septic system to avoid this costly replacement.

    I had no idea that it is important to schedule cleanings for your septic tank every two to three years with a company that you trust, so I’m glad that I found this article! My sister moved to a fixer-upper home in the country last month, and she has noticed some issues with the sinks clogging. I will let her know that it would be best to hire a professional to come to clean out the septic tank to fix the problem.

    Thank you for mentioning how knowing where your septic tank is located will allow a septic system professional to access it quickly. My wife and I are interested in having our septic system pumped before we invite our nephews to spend the summer with us, but we are not sure where the system is located since we recently bought our home. We’ll hire a professional that can help us locate and pump our system.

    Thank you so much for your advice to not park cars over the septic tank as this puts unnecessary pressure on the tank walls. About a week ago, I was talking to my sister, and she mentioned that she is thinking of building a new home outside of the city. I think the lot will require a septic tank. I will have to tell my sister about your tips and help her look for pumping, maintenance services that could help keep things running smoothly.

    It makes sense that you should avoid putting paper towels down the drain since it can clog your pipes. Recently, my son has been flushing paper towels down the toilet whenever it is his turn to clean the bathroom. It may be best to have my septic tank pumped before it begins to clog.

    Thanks for helping me understand that the tank should be scheduled for professional inspections at least every two to three years to keep it in good condition. I guess I need to call one already because we have moved into this house in April of 2016 which means that we are already three years here. We have never thought of getting it checked until now that it sometimes produces a foul odor.

    I like what you said about homeowners being able to clean out septic tanks themselves. However, contacting a reliable company is the first step towards getting a septic tank in the first place. I will be sure to contact such a company if I ever make the decision to install a septic tank system on my large property.

    My uncle recently moved to a home with a septic tank, so he’s been wondering how to care for it. It was helpful when you mentioned that a septic tank should be pumped every two to three years.

    My husband and I are looking into buying a new house and the one we would really like has a septic tank. He had heard that he could potentially save money by pumping the cesspool himself, but I am not entirely comfortable with him doing so. Your information that we will need to store the sludge and find a way to safely dispose of it makes me more inclined to hire a septic service to take care of this for us.

    I try and tell my wife that the baby wipes she flushes are bad for the system. She needs to read this article and learn. I don’t want to have to have some emergency work done to fix any issues that it could cause.

    It really helped when you said that we could find a good septic company by checking third-party websites and getting estimates. I think that is true because the testimonials of their previous customers can tell a lot. I will be following this advice because we needed our septic system checked. It has been producing foul odors around our house, and we don’t have any idea how to fix it. Thanks for the tips!
