Getting your home hooked up to the City of Raleigh’s Water and Sewer System means installing a sewer line from your home to the city’s mains. Homeowners pay an average of $2,322, but the cost to install a sewer line in Raleigh can range between $1,089 and $3,762. As you plan for your sewer line installation project, you’ll need to understand the cost factors and city requirements, so you can get hooked up correctly.
Sewer Line Installation Cost Factors
Sewer line installation in Raleigh will connect your home to the city’s sanitary sewer system. The cost to do this will depend on the sewer pipe material and the amount needed to reach the main system. You’ll also have to factor in demolition and site prep costs.
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 to determine the pros and cons compared to the cost per linear foot.
| Type of Pipe Material | Average Cost (Per Linear Foot) | Pros | Cons |
|---|---|---|---|
| Clay | $50–$60 | Durable, resistant to corrosion and damage from chemicals, long-lasting | Common in older homes, likely needs to be replaced, prone to cracking and tree root intrusion |
| PVC | $0.50–$5 | Most affordable, smooth interior allows for faster flow and reduced blockages | Can collapse under heavy loads without proper installation, susceptible to damage from extreme temperatures |
| 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 and long-lasting, lightweight, fire-resistant | 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
Installing a sewer line requires a significant amount of excavation and removal of any obstructions in the area. Here are a few of the costs to consider:
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
Sewer Line Installation Pro Costs
Installing a sewer line in Raleigh requires several different permits and fees. Also add in labor costs and inspection fees to get the best idea of the total project cost.
Permits and Fees
Construction or repair work on sewer lines in the public right-of-way requires a Certificate of Eligibility and a maximum $5,000 bond. Sewer line installation will require Utility Connection, Utility Service, and Plumbing Utility permits. Fees are based on the diameter of the sewer main and cost around $70 to $225.
The City of Raleigh provides transparent permitting fees, and you can apply for these permits by filling out the Residential Permit Application.
There is also a fee of about $5,000 for 4-inch sewer installation services. The number and amount of fees will vary depending on your situation.
Labor
Sewer main installation should only be done by a qualified professional. Labor costs are well worth it to avoid a mistake during installation that could cost much more to fix. Plumbers and sewer line companies have labor rates of about $30 to $250 per linear foot. Ask your local sewer service contractor for an estimate that includes the expected labor costs.
Inspections
Raleigh requires different types of inspections depending on the project's details. For the Water and Sewer Service Connection Inspection, homeowners pay $113 per water and sewer service stub, and this fee will increase to $115 in the 2026 fiscal year.
Does Sewer Line Installation Increase Home Value?
Even though installing a sewer line from your home to the public sewer system is necessary, it’s unlikely to raise your home value. On the other hand, a damaged sewer main can have a negative impact on your home value because prospective buyers will have to factor in the costs to repair it. Keeping your sewer line in good condition with regular inspections and maintenance is the best way to avoid a lower home value as a result of a faulty sewer line.
