How Does Trenchless Sewer Installation Work?

A trenchless sewer installation is a non invasive way to replace your old, broken or failing lateral line with a new, seamless one. The process is both cleaner and faster than the old method of digging up half of your yard to remove the old piping and put in new.

Trenchless Sewer Installation

The process is rather simple. We dig two access holes to your sewer line – one at the connection to the city drain and one where the line leaves your home. A steel cable is run through your existing line and a large bursting head is attached to one end. A polyethylene pipe is attached behind the bursting head and then they are pulled through your existing line by a hydraulic motor.

The bursting pipe breaks the existing pipe and pushes the pieces into the surrounding soil while the new pipe fills in the vacated space. Once the entire run is completed, the bursting head is removed and the two ends of the pipe are secured to the home and city sewer system. You now have a new, seamless sewer line that is more resistant to root invasion and cracking.

How Much Will It Cost?

A typical trenchless sewer installation is going to cost between $100 and $200 per foot depending on the location of your sewer line and the type of landscape or hardscape above it. This is still much cheaper than a traditional dig job.

How Long Will It Take?

The project will take a couple of hours from start to finish with the majority of the time spent digging out the exploratory dig holes to thread the steel line.

How Long Will It Last?

Your new pipe will be made from High Density Polyethylene(HDPE). This pipe is corrosion resistant and highly flexible so shifts in the subsoil won’t crack it. This is something that traditional clay, PVC and cast iron pipes lack. And, the HDPE pipe is expected to last about 200 years. Replace it once and you never have to do it again.
