Sewer Line Installation Cost Factors
In addition to factors like sewer line length and the type of pipe, the cost of demolition and site prep impacts the total.
Sewer Line Cost per Linear Foot
The average cost to install a sewer line ranges from $50 to $250 per linear foot. Sewer line pipes are about 5 inches in diameter and run underneath your yard from your house to the main sewer drain. See the table below for a cost breakdown based on the linear footage.
| Length (Feet) | Average Cost |
|---|---|
| 25 | $1,250–$6,250 |
| 50 | $2,500–$12,500 |
| 75 | $3,750–$18,750 |
| 100 | $5,000–$25,000 |
Materials
To install a sewer line, you’ll need to purchase the pipes that connect the main sewer drain to your home. New pipes cost around $3 to $20 per linear foot. Factor in the type of piping material, pros and cons, and cost per linear foot.
| Type of Pipe | Average Cost (Per Linear Foot) | Pros | Cons |
|---|---|---|---|
| Clay | $50–$60 | Durable, resistant to corrosion, long-lasting | Common in older homes, likely needs to be replaced, prone to cracking |
| PVC | $0.50–$5 | Most affordable, good fit in mild temperatures | Doesn’t stand up well in extreme cold |
| Cast iron | $2–$10 | Highly durable, performs well in areas with heavy surface traffic | Prone to rust and corrosion, heavy material makes labor more intensive |
| Copper | $20–$30 | High quality, long-lasting | Prone to corrosion, can freeze in cold temperatures |
| HDPE | $4–$6 | Used with trenchless methods, resistant to corrosion, tree root intrusion, and chemical damage | Flammable, higher cost for skilled labor and specialized techniques |
Demolition and Prep
Trenching: $800 per 100 linear feet
Boulder removal cost: $650–$1,200 per boulder
Tree removal cost: $200–2,000 per tree
Pavement removal cost: $8–$15 per square foot

Permits and Regulations
Installing a sewer line in Charlotte involves adding to or changing a plumbing system and requires a permit. If you’re acting as your own contractor, you may be eligible for Homeowner Internet Permitting (HIP). You can contact the Mecklenburg County Code Enforcement department to determine your permitting needs or discuss the process with your sewer service contractor.
A connection to the existing public sewer main in Charlotte can take up to eight weeks, so it’s contact your local water company, like Charlotte Water, to schedule sewer line installation and hookup as soon as possible.
Labor
Labor to install a sewer line costs between $30 and $247 per linear foot. Some sewer line installation companies charge around $70 per hour. Talk with your sewer line repair pro in Charlotte, North Carolina, to determine how labor will affect the total cost of the project.
Does Sewer Line Installation Increase Home Value?
Installing a new sewer line doesn’t increase home value on its own. Because it’s a necessity, it’s not thought of as an upgrade or desirable feature, like a bathroom remodel or new windows. However, a damaged or outdated sewer line can decrease a home’s value, as the next owner will have to take over repairs or replacement.
Maintaining your system and staying alert to signs of a sewer line clog or other issues that could spell trouble, like gurgling noises or bad smells, will allow you to conduct repairs as soon as possible and keep the sewer line in good condition. You may be eligible for the Residential Street Main Extension Program, which can help eligible homeowners with the cost of the extension.
