What is Trenchless Sewer Repair?

Posted by Olivia Singer on Jul 27, 2020 4:46:56 PM

Sewer pipes are subject to harsh pressures underground. While routine maintenance can help prolong lifespan, many pipes eventually begin to deteriorate and require more thorough rehabilitation.

Point Repair or End-to-End?

Posted by Katie Breeden on Mar 21, 2019 11:49:51 AM

Determining the right sewer rehabilitation method for a given job is not always straightforward, as identifying a solution requires evaluating a pipe’s physical environment and condition. Without properly assessing these factors, municipalities risk only partially solving a problem with point repair. Or, an equally inefficient outcome, waste resources by doing more work than necessary with end-to-end repair. While some municipalities have rehab contractors that also provide consulting services to address what type of solution is best, at the end of the day someone must make a decision on how to repair the pipes. So what should be taken into account?

Comparing Light Cure Technologies

Posted by Pipeline Renewal Technologies on Mar 15, 2019 1:37:36 PM

Not all light-cure technologies (UV and otherwise) are created equal. Illumination source, wavelength, intensity, motion, heat and other factors impact performance in a variety of ways. Here we benchmark PRT's SpeedyLight+ (small diameter) and LEDRig (large diameter) against competing light-cure technologies.

The Evolution of Cured-In-Place Pipe

Posted by Katie Breeden on Jan 2, 2019 11:42:00 AM

Originally called “insitu form,” meaning “form in place,” cured-in-place pipe (CIPP) liners were developed in 1971 by Eric Wood in London, England. Prior to that, trenchless technology methods were limited to sliplining or grouting techniques. But those methods were less feasible: grout is a short-lived solution that is expensive to apply, and sliplining also requires grouting, a measure of trenching and results in significant diameter loss. Wood recognized the opportunity to improve rehabilitation efforts with liners that were cured directly inside the pipe, which led to the invention of CIPP liners. CIPP repairs the damaged pipe with a liner that, essentially, becomes a new, jointless pipe within a pipe. Wood successfully executed the first CIPP repair by pulling a felt liner impregnated with polyester resin through the pipe and finishing it with an ambient cure.

Repairing Service Connections

Posted by Nicole Lygo on Dec 20, 2018 11:50:27 AM

Within a sewer main, service connections are one of the largest sources of infiltration. Older sewer systems in particular may experience problems, as construction requirements and methods in previous eras were less concerned with tight seals and durability. During the first half of the 20th century, hammer taps were not uncommon. A hammer tap, commonly found with vitrified clay pipes, involves using a hammer to smash a hole in the main to accommodate the lateral. Gaps may have been filled with grout, but less conscientious workers also used miscellaneous items such as flattened tin cans or scraps of metal. Modern construction methods are significantly more precise and less leak-prone, but the service connection is still particularly susceptible to groundwater infiltration and many older connections remain in use.

The Cost of Expansion

Posted by Nicole Lygo on Oct 31, 2018 6:40:52 PM

With the possibility of more federal investment in infrastructure on the horizon, many municipal contractors are looking to increase their capabilities. American wastewater systems are rapidly degrading, so rehabilitation is one of the larger areas of growth. Depending on what type of work your business already offers, some rehabilitation methods may be easier to get into than others. For spot (point) repairs, the most popular options are CIPP spot liners (generally under four feet), mechanical point repair sleeves and grout. Each method has its strengths and weaknesses as a repair solution, and each one has variable costs in terms of initial capital and maintenance cost. Getting an idea of what different methods can cost may give you a starting point for choosing the best option for your business.

Grout is Out!

Posted by Katie Breeden on Sep 26, 2018 1:03:54 PM

When choosing the proper pipeline rehabilitation technique, repair teams need an effective and lasting solution. Trenchless or no-dig technologies are preferable to high-cost, high-risk trenching alternatives whenever possible, as they save resources and cause minimal disturbance during installation. Yet while all trenchless solutions bring these benefits, some prove to be more practical than others.
