When it comes to underground utility work, the race to create new and more efficient pipe replacement methods has created some uncertainty and confusion about the technology available in the industry.
Despite its growing adoption, many contractors, municipalities and utilities still misunderstand the full capabilities and benefits of trenchless pipe pulling. The reality is that trenchless technology offers faster, safer and more cost-effective solutions compared to traditional open trenching. One of the most advanced innovations that will benefit from additional clarity is the Kobus Pipe Puller (KPP400). It is a groundbreaking tool, unlike any other option in trenchless technology.
What is Trenchless Pipe Pulling?
Trenchless pipe pulling is a method of replacing underground pipes without the need for extensive excavation. Unlike traditional open trenching, which involves digging up large sections of land to access pipes, trenchless methods require only minimal ground excavation. This approach reduces disruption, project length and overall costs.
The Kobus Pipe Puller is a standout technology in this space. Utilizing an innovative hydraulic winch system and a specially designed pulling cable, the KPP400 completely removes old pipes while simultaneously laying new ones in a seamless operation. This cutting-edge approach solves many of the long-standing challenges in underground pipe replacement. Of course, many organizations leading pipe replacement projects don’t yet realize the equipment’s capabilities. Unfortunately, these misconceptions about the technology cost crews time, money and safety.
Myth #1: Specialized Equipment Means Expensive Projects
One common misconception is that using advanced equipment like the KPP400 must come with a higher price tag. However, the opposite is true. Trenchless pipe pulling with the Kobus system eliminates the need for extensive excavation, reducing labor and reinstatement costs which can run as high as $300 per linear foot.
Only two small access points are required, drastically lowering the cost of site restoration. Operation of the KPP400 is done from a compact excavator, requiring a smaller crew and less expensive equipment than traditional methods. The efficiency of the pipe-pulling process—removing and replacing up to 80’ of pipe in a single pull—shortens project timelines, reducing labor hours and allowing contractors to complete more jobs in less time.
While utilizing the Kobus Pipe Puller does require an additional up-front cost, that investment is quickly recouped through less labor, minimal reinstatement costs, a reduced need for expensive equipment and more efficiency. Since its launch, the KPP400 has repeatedly demonstrated that it can complete projects in high-traffic urban areas in half the time of traditional methods.
Myth #2: Traditional Methods Are Safer and More Accurate
Traditional open trenching methods may be considered safer alternatives, particularly when working near other utilities. Exposing the pipes before replacing them may offer additional visibility, but excavation remains inherently risky.
Trenchless pipe pulling with the KPP400 provides a safer and more precise solution. Using a hydraulic winch and a steel pulling cable to extract old pipes through a small pit protects against accidental utility strikes because the new pipe follows the exact bore path of the old pipe. Workers have peace of mind that the work won’t bring them into contact with active utility lines. The smaller and more contained work area also minimizes worker exposure to potentially hazardous conditions, such as deep trenches and unstable soil.
Myth #3: Pipe Pulling is Too Limited by Pipe Material and Size
Another point of confusion is that trenchless technology is too limited in its applications. However, the Kobus Pipe Puller provides operators with significant versatility in the types of pipes it can remove and the replacement materials.
The KPP400 is engineered to remove and replace lead, steel, copper, or plastic pipes ranging from ½” to 1″ inner diameter. The replacement pipes it will simultaneously tow into place can be either copper or polyethylene, with an inner diameter of up to 1.5″. In addition, the uniquely designed male and female spool halves, featuring a precision-engineered helix thread, enable an effortless separation to quickly remove the old coiled pipe after extraction.
It’s also a fact that the technology is equally well-suited for projects targeting water or gas service lines. Its ability to remove pipes of different sizes and materials while upgrading them with today’s preferred options makes the KPP400 ideal for most projects, whether it’s replacing small residential service lines or addressing more extensive municipal needs.
Myth #4: Open Trenching is More Environmentally Friendly
It’s not uncommon for open trenching to be seen as the preferred option for those with environmental concerns. Unlike some types of trenchless technologies, like pipe bursting, which leaves the remains of decommissioned pipes underground, open trenching gives contractors access to remove the old pipes.
However, pipe pulling accomplishes removal without sacrificing the ground above. With only small access points required, the surrounding environment—whether it’s grassy lawns or active streets—remains intact. The KPP400 also relies on less powerful equipment than heavy-duty excavation machinery, resulting in lower fuel consumption and emissions.
Myth #5: Trenchless Pipe Pulling Remains an Unproven Technology
Lastly, some will assume that trenchless pipe pulling is a relatively new and unproven method. This is far from accurate. KOBUS’s roots in the United Kingdom have allowed it to perfect the technology in a region with centuries-old infrastructure and some of the world’s most challenging environments. The KPP400’s proven track record has been refined by decades of innovation and tested by practical application in complex pipe networks across Europe.
Now headquartered in Houston, Texas, KOBUS has been successfully operating globally for several years and has been vetted by some of North America’s largest municipalities, gas utilities and contractors. With thousands of successful replacements across multiple states, its high-quality components ensure durability and make it virtually maintenance-free.
