Concrete is a common septic tank material in Minneapolis because of its durability, but installing it is challenging.
In Minnesota, about a third of residents have a septic system to dispose of household waste and water. The cost to install a septic system in Minneapolis averages $6,614 and ranges from $5,575 to $8,000. A sewer pro can give you an estimate based on the tank material and size, as well as the cost of site prep, labor, and permits.
Septic System Installation Cost Factors
Installing a septic system in Minneapolis requires choosing the right tank size for your home and the best material. The cost will depend on these factors, as well as the type of system and the amount of site preparation you need.
Tank Size
The septic tank size you need will depend on the number of bedrooms your home has. For a three- or four-bedroom home, you’d need a 1,000-gallon septic tank, which costs $1,250 to $1,500 for the tank alone.
Larger houses have more sinks, toilets, bathtubs, and other wastewater sources that flow into the septic tank. As tank size increases, so do costs.
| Household Size (Bedrooms) | Tank Capacity (Gallons) | Average Cost |
|---|---|---|
| 1 | 500 | $500–$900 |
| 2 | 750 | $900–$1,200 |
| 3–4 | 1,000 | $1,250–$1,500 |
| 5–7 | 1,500 | $1,500–$3,200 |
| 8–9 | 2,000 | $2,300–$3,450 |
Materials
Septic tanks are commonly made of plastic, concrete, or fiberglass, with fiberglass being the most expensive. Concrete is a popular septic tank material in Minneapolis thanks to its strength and durability. Here’s how much a tank costs based on each material.
| Piping Material | Average Cost | Pros | Cons |
|---|---|---|---|
| Plastic | $1,100–$3,200 | Lightweight, easy to install, less expensive than fiberglass | Less durable, more prone to cracking under the pressure of soil |
| Concrete | $1,800–$2,400 | Highly durable, most common type | Prone to cracking, labor will significantly increase the cost |
| Fiberglass | $3,200–$4,10 | Nonporous to protect against algae growth, lightweight, easy to install | Can crack during installation, more expensive |
Type of Septic System
Each type of septic system comes with its own set of pros and cons. While anaerobic systems are relatively low-maintenance, they aren’t great for small properties. Similarly, anaerobic systems can do well in small spaces but require extra work.
| Anaerobic | Aerobic |
|---|---|
| Anaerobic bacteria break down waste | Aerobic bacteria break down waste |
| More affordable | More expensive |
| Uses fewer chemicals | More efficient |
| Needs a larger leach field | Good for smaller properties |
Anaerobic: Anaerobic systems are more common and cost $3,000–$8,000. They’re less costly than aerobic systems and don’t need extra power or chemicals, but they’re less efficient and require a larger leach field. A pipe runs from the house to the septic tank, where another pipe runs into the leach field. Anaerobic bacteria break down solid waste before the system distributes the wastewater into the soil.
Aerobic: Aerobic septic systems utilize oxygen pumped into the tank to activate bacteria that feed on the solid waste. They’re more expensive at $10,000–$20,000 but are more efficient and work well on smaller properties. They require additional power to run, so hook yours up to a power generator in case of a power outage. Otherwise, these systems can plug into your property’s main power source.
Site Prep
Site prep in Minneapolis includes conducting a land survey and a percolation test to identify your property lines and the soil condition, and installing a leach field to transport the wastewater to the soil.
Land Survey: You’ll need to get a land survey before installing a septic system to ensure your plans fall within property lines. Expect to spend $330–$900 to hire a licensed land surveyor.
Percolation Test: Before the installation, you need a local perc test pro to perform a percolation test. The test measures water drainage in the soil, soil type, and the height of each sediment layer on your property to determine the best type of septic system for you. The cost to test your soil is $700–$2,000.
Leach Field Installation: Septic tank systems consist of a septic tank and a trench referred to as a leach field or drain field. This section of the system transports the wastewater back to the soil. Drain field installation costs $5,000–$12,000.
Septic System Installation Pro Costs
A septic system pro in Minneapolis, Minnesota, can recommend tank size and materials and help you obtain the proper permits before starting the installation.
Labor
The State of Minnesota requires that on-site septic professionals be licensed by the Minnesota Pollution Control Agency (MPCA), so it’s important to verify your septic system professional’s licensing. The excavation and labor for installing a new septic system can cost between $2,000 and $4,000.
Permits
Permits and inspections to ensure that your septic system is designed and installed properly will cost between $500 and $1,000. Your septic tank installer can help you navigate the Minneapolis permitting process so you meet all necessary requirements.
Does a Septic System Increase Home Value?
Because homes with a septic tank can rarely be connected to a public sewer system, having a septic system doesn't necessarily impact a home’s value in Minneapolis. Instead, buyers are more likely to expect this feature.
However, if the septic system is poorly maintained, it can decrease the home’s value because prospective buyers will have to invest in the cost of septic tank repairs and getting it pumped. Otherwise, they’ll have to make sure that the seller takes care of it before finalizing the sale. A well-maintained system, on the other hand, can ease a buyer's mind.

I used Ken’s years for the 2021 season. On one of their visits their crew damaged an electrical junction on the rear of the house that’s low to the ground. They also destroyed the cap for the heating oil fuel tank on the side of the yard. When I initially reached out to the business they...

After being told it would be challenging to drain our old steel expansion tank, and that we should purchase a new boiler for other reasons, we got a few bids for a new boiler. Greg came and thought there was no reason to replace our boiler, as long as we drained the expansion tank and placed...

This spring, we noticed that the amount of hot water we had at any given time was shrinking. We tried to drain it to see if that would help--it didn't. We weren't under the gun to replace the water heater (it was still working, we just had very short showers!) so we had a little time to...

Like many snowblower owners, I don't think much about my blower until I need it. When I went to get it in late December during a big storm, it wouldn't start. I wasn't entirely surprised, as I had never taken the unit in for any service. (The blower is about six years old.) Jeff came the...
