A new sewer line has to be right the first time. It has to slope continuously toward the main, reach a connection point that may be a long way off, and get there without wrecking a driveway, a mature tree, or a foundation. That makes installation a planning problem before it is a digging problem. At US Trenchless, we install new sewer lines where none exists or where an existing path can’t be reused, and we use trenchless methods wherever the ground and the route allow. To talk through a new line for your property, call 877-916-7473 or request service online.

When You Need a New Sewer Line Installed

  • A new home, building, or addition that has to be connected to the sewer main
  • A property with no usable line, or one that was never connected properly
  • A line that has to be rerouted around a structure, a tree, or a changed property layout
  • A commercial site that needs a new connection or a different path to the main

If you already have a sewer line that is failing, you are likely looking at sewer line replacement or sewer repairs instead. A sewer line inspection tells you which one fits.

Trenchless Sewer Line Installation With Horizontal Directional Drilling

For new lines, we use horizontal directional drilling. A drilling machine bores a path underground, a drill head is guided along the planned route, and the pipe is pulled through behind it. The route is surveyed and measured before drilling, so the pipe ends up where it was planned, at the grade it needs.

The advantage is on the surface. Driveways, walkways, landscaping, and root zones stay in place, with only entry and exit pits dug. Some routes are not suitable for drilling, and those may still need an open trench. We’ll tell you which applies after we look at the site.

What Goes Into Planning a New Sewer Line

  1. Site review. We look at where the line has to start, where it has to connect, and what is in between.
  2. Route and grade. A sewer line works by gravity, so the route has to hold a continuous downward slope to the connection point.
  3. Utility marking. Underground utilities along the path are located and marked before any digging starts.
  4. Permits and inspections. New sewer connections generally need approval from the local sewer agency, and the agency may inspect the work. Requirements vary by agency.

Why Choose US Trenchless for Sewer Line Installation

We hold a California General Engineering (“A”) license, #971065, the license class that covers underground work like sewer and pipeline installation. Every installation starts with a site review and a planned route, so you know where the line will run and how it connects before the first hole is dug.

Sewer Line Installation FAQs: Permits, Routing, and Site Conditions

Does a new sewer line installation need a permit?

Generally, yes. New sewer connections are usually regulated by the local sewer agency or the city or county building department, and the work may need to be inspected. Requirements differ by agency, so confirm yours before work starts. We can walk you through what applies to your property.

What is the difference between sewer line installation and replacement?

Installation puts in a line that doesn’t exist yet, or on a new route. Replacement swaps out an existing line that has failed. The two are different jobs with different planning, which is why we handle them on separate pages.

Can a new sewer line be installed under a driveway, patio, or tree?

Often, yes, because directional drilling goes under surface features instead of through them. Whether it works on your site depends on the soil, the depth, and what else is underground, which we check before quoting.

What if the sewer main sits higher than my house?

A gravity line needs to slope down to the connection, so a main that is higher than the house may need a different solution. We’ll assess the elevations at the site visit and tell you what the property needs before you commit.
