A question frequently asked by homeowners is, “How much does it cost to change or install a septic tank?” The answer depends on a number of factors, including the specifics of your terrain, the type of septic system chosen and the associated installation costs. In this article, we present an overview of the main factors influencing price, and some practical information to guide you through your project.
Repairing or replacing a septic tank?
Before proceeding with a complete replacement, it’s important to consider whether a repair might suffice. A defective part or a minor problem can sometimes be repaired, saving you thousands of dollars on a new installation. A professional inspection, such as the one carried out by Septic Tank SV, can determine whether a repair is possible or whether a complete replacement is necessary.
Types of septic tank: which one to choose?
When it comes to installing or replacing a septic tank, two main types of systems are available:
- Septic tank with drain field
- Sealed septic tank
Septic tank with drain field
This is the most common system. After separation of the solids in the tank, the wastewater is directed to a leaching bed where it infiltrates the soil for natural biological treatment.
Sealed septic tank
Ideal when the terrain does not permit the installation of a septic field (for example, in areas with low permeability soils). This type of hermetic tank retains wastewater, requiring frequent emptying. Septic Tank SV offers emptying services for this type of tank, even in winter.
What factors influence the cost of installation?
The total price of a septic system depends on several factors:
1. Type of land
The configuration of the site plays an important role. Here are a few factors that can influence the cost:
- Slope or inclination of the terrain.
- Soil infiltration capacity.
- Proximity to waterways, wells or your home.
Difficult terrain often requires additional work, such as drainage systems or retaining walls, which increases costs.
2. Materials used
Septic tanks are generally made of concrete or polyethylene. Here’s an overview of average prices:
- Concrete septic tank: $1,000 to $3,000 (depending on size).
- Polyethylene septic tank: $1,700 to $3,500.
- Sealed concrete pit: $1,500 to $3,000.
- Polyethylene sealed pit: $2,700 to $5,000.
3. Additional installation costs
In addition to the cost of the pit itself, you’ll need to factor in the cost of the materials required for installation (sand, crushed stone, pipes, fittings, etc.). Here are some examples of total costs, including installation:
- Sealed pit: $3,000 to $6,000.
- Septic tank with drainfield: $5,000 to $8,000.
- Systems with advanced secondary treatment: $10,000 to $45,000, depending on options chosen (UV, phosphorus removal, polishing field).
4. Workforce
The cost of labor depends on the accessibility of your site. Difficult-to-access terrain requires more time and equipment, which increases costs. It’s essential to call on a specialized company like our partner Soluo to guarantee a compliant, durable installation adapted to the particularities of your terrain.
