What is a trenchless sewer line?

Answer: Pipe that isn't put in ground

Answer: Relining of pipe

Answer: A trenchless sewer line, also known as trenchless technology or no-dig technology, is a method of installing, repairing, or replacing underground pipes without the need for extensive excavation. Traditional sewer line replacement methods involve digging large trenches to access and replace the damaged or deteriorating pipes. However, trenchless sewer technology revolutionizes this process by offering more efficient, cost-effective, and less disruptive alternatives. The primary advantage of trenchless sewer technology is evident in its name – it eliminates the need for extensive excavation. Instead of digging trenches along the entire length of the sewer line, specialized equipment is used to access the pipes through small entry and exit points. This significantly reduces the disruption to the surrounding environment, whether it be a residential neighborhood, commercial area, or public space. There are several trenchless methods employed for sewer line installation, repair, or replacement, each catering to specific needs and conditions. One common trenchless technique is pipe lining, also known as cured-in-place pipe (CIPP). In this method, a flexible resin-saturated lining is inserted into the existing damaged pipe. The lining is then inflated and cured in place, creating a new, durable inner pipe. This technique is particularly effective for repairing pipes with cracks, leaks, or minor structural issues. Another trenchless method is pipe bursting. In this process, a bursting head is pulled through the existing pipe, breaking it apart as it moves forward. Simultaneously, a new pipe is pulled into place, filling the void created by the bursting head. This method is often used for replacing old or damaged pipes with a new, high-density polyethylene (HDPE) pipe. One of the most innovative trenchless technologies is microtunneling. This method utilizes a remotely controlled, guided boring machine to excavate a tunnel for the new pipe installation. Microtunneling is

Answer: A trenchless sewer line is installed by excavating the 2 connection points of the line and pushing a rod from one hole to the other and then by pulling back a soft plastic pipe back. This works for a new installation but requires very specific equipment and highly trained crew in order to get the slope correct. A replacement line is installed my threading a rod or cable through the existing line and again pulling back a new line. This also requires very specific equipment and knowledge. The price on trenchless installation is typically higher than excavation due to the very expensive equipment needed.

Answer: HDPE pipe bursting or CIPP pipe lining

Answer: There's 2 forms of trenchless, there is trenchless "pipe bursting" usually done within the property which requires 2 holes, one hole for the pipe entry point and the other got the hydraulic ram that pull new pipe through. Then there's trenchless liner, this method is more ideal when roots or broken section are located in the street (public right of way). This method only requires one hole as apposed to the other option.

Answer: Bibe burst slip liner.eliminates excavating the whole line.

Answer: Similar to a bore, does not require backfilling
