The tool used to remove the hubcap on the Quick-Change Hubs has been updated from the small ring to a more substantial handheld tool.

Seattle-based Trenchless Pipe Repairs (TPR) is a residential, commercial and small mainline rehabilitation contractor. TPR was founded 2011 by Nick Patrick, whose previous sewer rehab experience includes serving as CIPP Manager for Applied Professional Services, President at Insta-Pipe Inc. and CIPP Trainer for Northwest Trenchless Services. The company has carved a niche in the Pacific Northwest performing residential and commercial lateral rehabilitation, as well as sectional relining, lateral connection relining and pipe inspection for municipalities. Where new companies find it difficult to get a foothold in this industry—TPR thrives. The success TPR has experienced in the Pacific Northwest can be attributed to its comprehensive approach to rehabilitation.

When evaluating a sewer inspection crawler for purchase, don’t get distracted by bells and whistles—pay attention to design attributes that keep cost-of-ownership low. These attributes are evident in the core design of the crawler:

In 2016 Envirosight, will expand its offering of Preferred Build-out (PBOs)— vehicles designed for the efficient, productive deployment of sewer inspection equipment. The expanded offering includes the addition of a Ford Transit chassis option with a gas generator. Feature enhancements include expanding the capacity of wash-down tanks from 10 gallons to 18 gallons in most packages; installation of all generators with a dedicated battery (which improves access); a full cork board wall above the operator’s desk; and custom shelving with tool holders above the equipment bay workbench.

Recently, a city fire truck got stuck in a sinkhole in Lancaster City, PA. The sinkhole was caused by an abandoned sewer lateral that was not sealed off from the sewer main. The sinkhole caused a wide swath of soil about 3 feet deep to disappear under the street. Fire crews reported that damages could have been an upwards of $800,000 if the fire truck had toppled over.

Maximizing your sewer inspection crawler’s travel distance often comes down to one thing— proper wheel selection. With the appropriate wheels, crawler operators can ensure maximum ground clearance and sidewall contact, plus limit camera vibration and enhance tread grip.

The ROVVER X Laser Profiler gives inspection crews the ability to analyze the ovality, alignment, diameter and capacity of a pipe using projected laser light. The profiler projects a ring of light on the pipe wall, and then software extracts the profile from the camera video and trends it over the length of the pipe to build a geometric profile. The captured profile data is readily analyzed to verify proper pipe installation, plan relining projects, determine remaining pipe life, monitor erosion/corrosion, quantify defects and analyze partial collapses.

Sewer Technologies Inc. bought their ROVVER X system a little over a year ago and recently emailed to say how satisfied they are with it. They deal with some very harsh conditions and buying a CCTV inspection system that could perform under those conditions was a priority.
