Septic Tank Cost Factors 

Your total cost to replace a septic tank in Columbus, OH, will depend on the tank size your home needs, which is determined by the number of bedrooms. Tank material will also factor into the cost, with variations between concrete versus plastic septic tanks, for example. Any cleanup or demo work will also add to the project cost.

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 $860 to $1,430 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.

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.

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.

Replacing your septic tank can increase home value, with most homeowners enjoying a 5% to 10% increase. Potential buyers always appreciate newer systems because it means they won't have to worry about making their own upgrades after moving in.

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.
