Trenchless Sewer Repair in Denver: What Is It?

The traditional method of repairing sewers typically involves a lot of digging and collateral damage. The repair person has to dig out a hole in the property owner’s yard that is the entire length of the pipe, usually with heavy-duty equipment like an excavator. If the pipe’s located directly underneath pavement or utility lines, those structures will need to be worked around or be repaired as well.

Trenchless sewer repair solves piping issues with far less mess and disruption. It works internally by pulling the new piping through the old line rather than having repair people work on an exposed pipe. The result is a practically new sewer line pipe, obtained with very little intrusion, much smaller machinery, and little to no damage to landscaping.

Sewer Lines Only specializes in trenchless sewer line repair in Denver. Our staff uses the most current techniques to fix sewer line problems in an effective and cost-efficient manner.

Trenchless Sewer Line Repair in Denver: How Does It Work?

The first step in trenchless sewer repair is digging two pits: one for entry and one for an exit. These pits are the hubs through which all the repairs take place—and the only holes that are ever made in the process. They only need to be wide enough to accommodate the new pipe that’s going through them.

The process of replacing the sewer line in trenchless repair is called pipe bursting:

The new sewer pipe is fitted with a bursting head at the front so the pipe can bore its way through the old pipe.

The replacement pipe is inserted into the entry pipe and is gradually pulled through the underground pipe using a hydraulic power generator.

As the new pipe travels along the sewer line, it fractures and breaks the old pipe into fragments so it can fit—that’s why the process is called “pipe bursting.”

Depending on the length and depth of the pipe and the extent of the repairs, trenchless sewer line repair can take varying amounts of time. However, most of the time the repair is completed within 1-day.

Trenchless Sewer Line Replacement in Denver: Advantages over Traditional Repair

  • It’s less invasive. The trenchless method involves digging only two pits to pull the pipe through. Traditional sewer repair often involves excavating the entire length of the old pipe, and many times involves digging or damaging landscaping, driveways, or other fixtures unconnected to the sewer.
  • It causes little, if any, disruption to utilities. Since trenchless sewer repair is a quick process, the disruption to the homeowner’s utilities is minimal. Water service in the property home may need to be temporarily suspended, but not for long.
  • It’s environmentally friendlier. The trenchless method keeps the old, now burst pipe within the ground, which creates less waste above the surface. Not having to dig a trench also means not having to discard old dirt fill or expose underground toxins. The trenchless process doesn’t use any potentially harmful chemicals.
  • It takes less time. Trenchless sewer repair can be fully completed within one to two days. By contrast, a traditional repair can take anywhere from one to three days—and that depends on the size, age, and condition of the pipe, the scope of the damage, and whether additional repairs to other structures are needed. For big problems or pipes, traditional repair time can take even longer.
  • It’s more cost-efficient. In the traditional method, there may be additional landscaping repairs such as grass, concrete patios, asphalt or sidewalks to repair.

With all in its favor, trenchless sewer line replacement in Denver is a solid option for property owners seeking a simpler solution to sewer issues.

Trenchless Sewer Replacement in Denver: Is It Right for My Home?

Signs that you need sewer repair can be obvious or hidden. Some of the issues and symptoms that trenchless sewer repair in Denver covers include:

  • Pipe blockage or sewer backup
  • Cracks and breaks, whether the pipe is made from clay, lead, cast iron or plastic
  • Corrosion and other rust-related damage
  • Weather damage, such as expansion or cracks from freezing or thawing
  • Misaligned or warped pipes
  • Damage caused by deep tree roots

Certain circumstances make more ideal cases for trenchless sewer repair. It’s especially good for sewer pipes that are under significant landscaping.

There are a few situations when trenchless pipe repair may be difficult or impractical. Pipe bursting can be hard to accomplish in sewage systems with a lot of bends or turns in the pipes. If the existing pipe has collapsed or degraded to an irreparable state, trenchless pipe repair probably cannot help. Lastly, if a pipe has a belly or a low spot it is not advisable to perform a trenchless repair because the new line will mimic the existing pipe. In Denver, trenchless repairs need to be approved by the City of Denver and a hold harmless document needs to be signed by the homeowner.

Trenchless Sewer Line Replacement in Denver: Costs Compared to Traditional Repair

Trenchless pipe repair can save money because there is less time spent excavating and there’s no damage to outlying structures like landscaping, sidewalks, utility structures, or the street.

In traditional sewer repair, if excavators have to expose pipe that lies beneath any of those surfaces, the property owner will usually have to pay the costs for their repair and restoration.

Pipes that have been installed using trenchless replacement are durable. High-density polyethylene (HPDE) is known for its extended durability.
