Septic Tank Cost Factors
Costs to replace a septic tank in Detroit, MI, primarily depend on tank size, which is determined by the number of rooms in a home. Tank material is another common cost factor, with concrete and plastic septic tanks being less expensive than fiberglass tanks.
Size
The septic tank size you need depends 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 $900 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.
| House Size | Tank Size (Gallons) | Average Cost |
|---|---|---|
| 1 bedroom | 500 | $500–$900 |
| 2 bedroom | 750 | $700–$1,200 |
| 3–4 bedrooms | 1,000 | $900–$1,500 |
| 5–6 bedrooms | 1,200 | $1,200–$1,600 |
| 6–7 bedrooms | 1,500 | $1,500–$2,500 |
Septic Tank Material
Septic tanks are commonly made of plastic, concrete, or fiberglass, with fiberglass often being the most expensive. Here’s how much a tank costs based on its material.
| Material | Average Cost |
|---|---|
| Plastic | $500–$2,000 |
| Concrete | $700–$2,000 |
| Fiberglass | $1,200–$2,000 |

Demolition, Prep, and Cleanup
Replacing a septic system often involves excavation and clearing trees or roots. Since excavation can be a messy work, many homeowners add sod over their yards or even regrade their yards at the end of a septic tank replacement for a finished look.
| Prep Work | Average Cost Range |
|---|---|
| Excavation | $1–$5 per square foot |
| Tree/root removal | $200–$2,000 |

How Angi Gets Its Local Cost Data
To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.
Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.

<p>Kevin did an excellent job. He was communicative, charged a fair rate, and was personable. I would hire this company again no questions asked. He even offered to show me how to purge the tank myself so I wouldn't have to hire a plumber again (if the need comes again).</p> <p>A++++++++</p>
