WRT Customer Update

To our valued Customers,

Over the course of the last 7 days, we at WRT and PLI, have become aware that one of our prior owners, Jerry D’Hulster and other prior employees of PLI, have started a company called Paramount Pipe Lining Products.

Jerry left PLI a year ago and he has nothing to do with the original products from PLI that  you’ve been buying for many years. Perma-Liner has established service, product support, quality system and engineering teams that are of the highest caliber and have proven that for decades.

I want to let you know that since becoming CEO in October of 2019, we have been breathing new life and meaning into servicing you, our long-term customers. Additionally, we are investing in your future and our future with new products, new technologies and new teams of professionals to support what you do every day.

Chris Duda our VP of Sales and Marketing along with Rob Larsen, whom you’ve known for years, are two of the most customer supportive people I’ve ever had the honor of working with. We are all here for you and because of you. We will not let you down.

If there is anything you need from us don’t be shy. We’re here for the long haul and we’re here because we appreciate all that you’ve done for us, today and every day.

NASTT’S TRENCHLESS TODAY: In The Trenches By Andrew Farr

Amana Arayan


For manufacturers and technology providers in the niche trenchless industry, properly communicating the value of trenchless solutions and touting your products through targeted marketing is key – it’s also Amana Arayan’s forte.

As marketing manager at LMK Technologies (LMK). Arayan has spent the past eight years in the industry implementing marketing campaigns and developing new ways to connect product with customer for the Ottawa, Illinois-based lateral rehabilitation company. She brings a singular skillset to her position, separate from the engineering perspective of her colleagues, that has allowed LMK to grow its brand recognition in the marketplace. She’s also taken the opportunity to go beyond her job at LMK and become fully engrained in the industry through her volunteer work with organizations like NASTT and NASSCO.

“Our industry has a huge impact on the daily lives of so many people, most without realizing it,” she says. “Although this is a dynamic and competitive field, everyone is working toward the common goal of minimizing the global footprint of this industry while discovering the next big idea in innovation.”

Trenchless Team Effort Yields Success in Downtown Minneapolis

Located in the heart of Minneapolis, Minnesota, at the busy off ramp from Interstate 35 and the terminus of Highway 65, a few blocks away from US Bank Stadium and the downtown financial district, is the historic Francis Drake Hotel. Built in 1926, the Drake Hotel was initially constructed as a luxury hotel; it now serves as a temporary residence for homeless families and individuals.

Despite its age, neither the hotel nor its underground infrastructure had ever been updated. In early summer 2017, a sink hole was discovered below 5th Avenue South, caused by a failure in the hotel’s side sewer and its connection to the mainline.

This sink hole presented a major problem for the traveling public as thousands of cars rely on this corridor daily. To make matters worse, a nearby bypass tunnel, which allows traffic to avoid the downtown area, had also been partially closed for unrelated repairs and maintenance. This forced even more commuters onto 5th Avenue South, the site of the sewer failure. Moreover, the cost for a traditional open-cut rehabilitation method was estimated to be approximately $45,000 for this single repair and take several days to complete, disrupting nearby businesses. Decision-makers from the City of Minneapolis determined that an extended closure of 5th Avenue South 5th for an open-cut excavation to replace the side sewer and mainline connection would not be possible.

New ASTM Standard for Hydrophilic Gaskets Approved and Updates to ASTM F2561

Ottawa, IL — ASTM International, one of the world’s leading industrial standard-setting organizations, recently took favorable action on two standard practice proposals for the trenchless rehabilitation of the connection of a sewer lateral to a main using hydrophilic gaskets.

The first of these standards, ASTM F3240, is the standard practice for installation of seamless molded hydrophilic gaskets (SMHG) for long-term watertightness of cured in place rehabilitation of main and lateral pipelines. ASTM F3240 is the first and only ASTM standard that addresses seamless molded hydrophilic gasket sealing for all terminating ends of CIPP (mainline and lateral). This standard is guiding the industry to achieve long-term watertight rehabilitations and make cured in place pipe more comparable to new pipe more than ever before.

2018 Trenchless Technology Roundtable: The New Face of Trenchless Technology

While still considered a relative newcomer by some longtime professionals in the underground utility construction market, trenchless technology is a maturing market. In fact, the oldest first cured in place pipe project is nearing its 50th birthday, and the International Society for Trenchless Technology passed the 30-year mark in 2016.

The trenchless industry has steadily grown and has continued to drive new innovation to improve efficiency and cost-effectiveness. Yet, in order for the market to build on that growth, it is imperative to attract, engage and retain the next generation of leaders who will guide the industry for decades to come.
