Sewer Line Installation Cost


How Much Does Sewer Line Installation Cost?

The main sewer line is what will take all wastewater from your home to the municipal sewer system or septic system. This is an essential component of the plumbing system in any home or building. However, just like anything else, sewer lines don’t last forever which means, at some point or another, you may need to hire a professional service for a new sewer line installation, or to connect a new home to the municipal sewer line.

There are a number of factors that will determine the cost of installing this sewer line, with the characteristics of your property having a big impact.

Replacement vs New Line Installation

The installation of a new sewer line during a construction project is usually uncomplicated. This is because the groundwork is already in place and accessing the system is obstruction free. Replacing a faulty or damaged sewer line can be quite complex since excavation will typically be required.

Having to remove the existing pipes can increase the manpower and time required for the project. Replacement services are typically higher on average. However, related repairs and the clean-up work necessary can increase the overall cost to install a sewer line even more.

It's absolutely crucial to use a professional for your sewer line installation if your city isn't doing it. A licensed professional can help walk you through the process and explain all the costs involved before any work is done. Be sure to compare at least 3 quotes before you go ahead and have any work done.

How Much Does It Cost To Install a Sewer Line?

It is important to note that the cost to install a sewer line will vary from home to home.

A new installation can cost, on average, around $2,000 to $2,700. However, the amount of earthwork that is involved and other preparation will affect the overall expenses.

On a national average, the cost of sewer line installation is around $3,000, with the high range being upwards of $7,000. When it comes to installation, the cost can also be affected by whether or not there is a septic tank present, or if your line will be connected to the main sewer line or not.

Sewer Line Installation Cost Breakdown

The 2 main cost considerations to be aware of when looking into sewer line installation are the fees charged by a sewer agency or municipality, and the second is the actual cost of hiring a plumber to install a sewer pipe from your home to the city's main sewer line.

New Sewer Line Connection

Sewer line connection fees vary according to the region you live in and should cost anywhere between $500 and $7,000. However, if a new sewer line has to be installed from scratch, it can, in some cases, cost $15,000+.  It would be wise to get in touch with local professionals to get a clearer idea of what you should be paying.Homeowners wanting to connect their sewer line to a municipal sewer main line will usually be charged a percentage of the overall sewer line installation cost.

Cost Examples

The city of Portland, Oregon, charges roughly $5,000 per pipeline branch on top of a $4,500 sewer system development fee. In Florida, sewer line connection fees are based on your property size.

Consider the average costs for property sizes for Florida in the following table:

Property Size Average Cost
Up to 3000 sq ft $1,600
3001 - 5000 sq ft $2,100
Over 5000 sq ft $3,400

Sewer Pipe Installation Fees

Installing a new sewer lateral on your property can cost $1,000 - $40,000 or more depending on the following factors.

  • distance from the main sewer line
  • terrain
  • access to the property
  • local rates
  • building and plumbing code requirements

In Oregon, the estimated cost to add a sewer lateral is $1,500 - $2,500, while in California a predictable cost is typically $4,000 - $6,000.

Sewer Line Length

The total distance between the main sewer line and building is also an important factor to consider when having the line installed. This is because the material and time requirements of the job will go up as the job increases in size. The process of fitting and then laying a line is usually based on length:

  • Less than 100 ft will usually cost approximately $1,463
  • 100 ft - 200 ft around $2,519
  • 200 ft - 300 ft approximately $3,802
  • 300 ft or more can be upwards of $5,532

While the distance between the building and sewer is a good indication of the requirements of the job, earthwork, that is necessary to create a pitch for draining or repairs to the current lines can cause the cost to go up. Excavation costs could be anywhere between $500 - $20,000 depending on location, terrain, and time needed. On average, $40 - $150 an hour.

Installing a new sewer line requires a lot of time and effort, and should only be completed by a professional. By hiring a pro you wont have to worry about damages to your home, or the reliability of the new sewer line installation. A good installer will take care of the old pipes and rubbel removal as well as handle any permits necessary in your state.
