How Much Does It Cost to Pump a Septic Tank in Chicago? [2026 Data]

The cost of living in Chicago, Illinois, is slightly higher than the national average, which can affect the cost of services like septic tank pumping. You can expect to pay between $249 and $504 for septic tank pumping in Chicago, or $347 on average. The cost to pump a septic tank in Chicago mainly depends on the size of your tank, though pumping frequency, the time of year, and additional services also affect the total cost.

Septic Tank Pumping Cost Factors 

The most important cost factors of septic tank pumping in Chicago, Illinois, include tank size, waste level buildup, seasonality, and tank access.

Size

Pumping a 600-gallon septic tank—like a small septic tank for one toilet—may cost as little as $250, while pumping a 2,000-gallon septic tank may cost $1,250 or more. The most common septic tank sizes, however, are the more moderately sized ones, averaging between 1,000 and 1,500 gallons.

Here’s a breakdown of septic tank pumping costs by size:

Usage

Tanks with high usage will require more frequent pumping. For example, if you frequently use large amounts of water, put food down the garbage disposal, or host parties with lots of guests, you’ll need to pump your septic tank more often. On the other hand, larger septic tanks take longer to fill and therefore require less frequent pumping.

Pumping Frequency 

The cost of septic tank pumping can rise sharply when property owners fail to have their tanks pumped every three to five years. 

Regardless of the type of septic system you have, not pumping it on schedule will cause solids to accumulate until a tank's holding capacity is depleted, resulting in a clog. On average, septic tank repairs cost $1,800, but they can range from $600 to $3,000, depending on the severity of the issue.

Tanks should be pumped more frequently in larger households. Pumping should also be more frequent if your home has a garbage disposal, you entertain frequently, or you often dump harsh cleaning solutions down your drains.

Here’s how often you should pump your septic tank based on its size and how big your house is:

Seasonality 

During certain times of year, especially in areas with harsh winters, demand for septic tank services fluctuates, leading to varying prices.

We don’t recommend booking a septic tank pumping in the winter months if your area gets heavy snow and ice. Frozen ground and slippery conditions make it more difficult for pros to access your tank, increasing labor and equipment costs.

Spring is the most popular time for homeowners to get their septic systems pumped and checked. The increased demand can cause prices to spike. If your tank isn’t too full, consider booking in the summer or early fall, when demand is lower. 

Access to Tank

If your septic tank is located in a hard-to-reach area, such as under a deck or on uneven terrain, it can make the job more challenging and expensive. Similarly, tanks that are buried deeper underground require more effort to uncover and pump, so it’s a good idea to budget for a higher pumping fee.

Septic Tank Ongoing Costs

Septic tank pumping is just one of the costs associated with properly maintaining a home’s septic system. Here are some additional services and ongoing expenses that are often associated with septic tanks:

Sewer Line Inspection

While the average price for a sewer line inspection is $400, homeowners can expect to pay anywhere from $350 to $550. Using a camera to inspect a sewer line, a plumber will look for issues that could lead to costly repairs down the road. Some of the red flags a sewer line inspection can uncover include line breakage, embedded objects, tree roots, and rocks.

Clog Removal

The average cost of septic tank repairs is $1,800. Clog removal is the most common septic tank repair because it's easy for objects to find their way down a drain. The most common method for resolving a septic tank clog is to use an auger to reach the clog.

Homeowners may not realize there's a clog until they notice telltale signs, such as slow-draining sinks, standing water near the tank, foul odors, gurgling sounds in the plumbing system, or water and sewage bubbling from toilets, drains, and sinks.

Maintenance 

While septic tank pumping is needed every three to five years, annual tank inspections and maintenance can help detect issues before they worsen. The maintenance technician can also let you know when it's time to pump. Septic tank maintenance costs range from $200 to $700. 

Field Aeration

Aeration is the process of upgrading a septic system without actually doing a major update. This process costs between $1,000 and $2,000 and revives sluggish septic systems without replacing the full leach field. It turns your system from an oxygen-free anaerobic system to an oxygen-rich aerobic environment.

Yard Cleanup

Yard cleaning is necessary if sewage from a septic system spills into the grass. While some people prefer to handle the mess by using bleach and water to disinfect the area, others hire professional yard cleaners to restore the area's hygiene and get rid of the septic smell outside. Lime is also frequently used to quickly break down sewage. Outdoor sewage cleanup costs an average of $7 to $15 per square foot. 

Septic Tank Cleaning

While the average cost to clean a septic tank is $400, cleaning costs for large tanks can run closer to $700.

Septic System Pro Costs

You’ll need to keep a few other potential costs in mind before hiring septic professionals in Chicago, IL. These may include fees for pumping in urban areas, severe grease clogs, and other septic maintenance services.

Location

Having a septic tank pumped in urban or suburban areas can cost $200 to $300 more if there are any issues accessing the tank with the pump truck. 

Fat, Oil, and Grease

High levels of grease and oil clog the septic system, making removal more time-consuming and difficult for your septic company. Pumping a tank in this condition often comes with extra charges—up to $500 in severe cases.

Extra Services

One of the most important parts of septic tank maintenance is keeping up with ongoing repairs and tune-ups. If you need extra services such as filter cleaning, effluent filter replacement, or baffle repairs, these will add between $200 and $800 to your total costs. 

Additional Pros to Consider Hiring

Landscapers can restore the area around your septic tank for $300 to $1,000 in Chicago, depending on the size of the area. Plumbers, on the other hand, help you deal with drain clogs, septic backups, and other wastewater issues. In Chicago, plumbers charge $45 to $200 per hour.

Does Septic Tank Pumping Increase Home Value?

Septic tank pumping doesn’t provide a specific return on investment (ROI). However, any would-be homebuyer would expect the septic system on your property to be in good working order, ensuring safety throughout the septic tank’s lifespan. To help ensure a quick, easy sale down the road, make sure to keep up with regular septic pumping and maintenance.
