Sewer Line Installation Cost Factors

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 about $3 to $20 per linear foot. The best type of sewer pipe for your project depends on your soil type. The soil in Austin ranges from expansive clay to stable deep sandy loam.
Factor in the type of piping material to gain a closer estimate as to how much you’ll pay per linear foot by referencing the following chart:

| ABS | $5–$11 | Resistant to freezing temperatures, lightweight | Sustains UV damage, can sound noisy, contains BPA |

Permits and Regulations
You’ll need a residential building sewer tap permit for a sewer line installation in Austin. The fee for the permit is $750, and a certified plumber must submit the application. You’ll also need an excavation permit, which costs $400.
Labor

Does Sewer Line Installation Increase Home Value?

A sewer line that’s in disrepair or needs to be replaced can dissuade potential homebuyers.
