Sewer Line Installation Cost Breakdown
Several key factors influence the cost of installing a sewer line, including materials, labor, trenching, permits, and local regulations.
Sewer Line Cost per Linear Foot
On average, installing a sewer line costs between $65 and $325 per linear foot. These pipes, typically around 5 inches in diameter, run from your house to the main sewer drain beneath your yard.
Materials
To install a sewer line, you’ll need to purchase the necessary pipes to connect your home to the main sewer drain. The cost of new pipes ranges from about $3.90 to $26 per linear foot, depending on the type of material used. Here’s a breakdown of average costs per linear foot for different piping materials:
Piping Material Type | Average Cost per Linear Foot |
Cast-iron | $2.60–$13 |
Copper | $26–$39 |
PEX | $2.60–$6.50 |
PVC | $0.65–$6.50 |
Cast-Iron Piping
Cast-iron pipes cost between $2.60 and $13 per linear foot on average. Older homes often have cast-iron pipes, but this material is becoming outdated due to its susceptibility to corrosion. Newer materials like PVC and PEX are now more commonly used in modern homes.
Copper Piping
Copper piping costs between $26 and $39 per linear foot on average. Despite being the most expensive option, copper is a long-standing choice for home plumbing due to its durability and reliability.

Polyethylene (PEX) Piping
Installing PEX piping costs between $2.60 and $6.50 per linear foot. PEX offers an affordable alternative to copper and provides better resistance to heat and cold compared to PVC, making it a versatile choice.
PVC Piping
PVC piping, the most budget-friendly option, costs between $0.65 and $6.50 per linear foot. PVC is both durable and economical, making it a popular choice for sewer hookups.
Labor
Hiring a licensed plumber to install the sewer line is essential. Labor costs for sewer line installation range from $39 to $321 per linear foot. Although it might be tempting to cut costs by DIY-ing, professional installation ensures the job is done safely and correctly.
Trenching
Trenching costs around $1,040 per 100 linear feet, depending on the length and depth required. This price typically doesn’t include removing landscaping or hardscaping before digging, so it’s wise to get a detailed quote beforehand. You might save on landscaping repairs if trenchless sewer repair is an option.
Backflow Preventer
To prevent backflow into your basement, you might need an overhead sewer, costing between $10,400 and $13,000 on average. These pipes run above ground to ensure waste doesn’t flow in the wrong direction.
Sewer Cleanout
A sewer cleanout costs between $650 and $2,600. These access points allow for clearing clogs or inspecting lines with a camera. A two-way sewer cleanout, which can cost up to $4,550, requires more work and potentially major excavation.
Permits and Regulations
Connecting to the city sewer line requires permits, costing between $520 and $2,080, with an average cost of around $1,300. Prices vary based on local regulations, and permits must typically be obtained before starting the project. If your plumber can’t handle the permits for you, make sure to get them in advance.
Housing Type and Sewer Line Installation Costs
The type of housing you live in can significantly affect the cost of installing a sewer line. Here’s a breakdown of how costs might be covered based on your housing type:
- Single-family Home: You are responsible for the entire cost of the sewer line installation.
- Twin Home: Both homeowners need to negotiate and decide who will cover the installation costs.
- Duplex: The property owner is responsible for covering the costs.
- Townhome or Condo: Your Homeowners Association (HOA) might cover the expenses, but this could lead to an increase in your HOA fees.
Additional Costs to Consider
When budgeting for sewer line installation, be aware of potential additional costs that could affect the total expense. Here are some common obstacles and their associated costs:
