The WEFTEC Show returns to New Orleans in 2014 (Sept. 27-Oct. 1) for its 87th annual event at the New Orleans Morial Convention Center, a five-day event that is expected to draw thousands of water quality professionals and exhibitors to the Big Easy.
For most of its history, the trenchless pipe relining and inspection market has centered on gravity sewer pipes. That seems quite natural, considering the fact that the cured-in-place pipe (CIPP) process — the forerunner of trenchless relining — was engineered specifically for gravity sewers.
Cleaning sewers with jetter trucks is a basic task of sewer maintenance departments around the world — so basic that it can be taken for granted and treated as just another chore.
Boring a small tunnel in hard rock is never an easy task, but when the rock is 28,000 psi UCS, the term “hard” doesn’t begin to cut it. That was the obstacle facing Virginia-based trenchless contractor Kruckenberg Service Co. at a set of utility bores for new sewer lines in Ashburn, Va., in late 2013.
Like many sewer districts, South Whitehall Township, in Lehigh County, Pa., is under an administrative order from the U.S. Environmental Protection Agency (U.S. EPA), along with 14 other Pennsylvania municipalities that all transfer wastewater to a common treatment plant in Allentown.
Spray-Applied Structural Lining Proves Its True Worth and Properties as Part of an Unusual Manhole Rehabilitation Demonstration
Mishawaka occupies one of the busiest intersections in “America’s Crossroads,” making it an ideal location for transporting people and goods across the nation and home to a diverse population of more than 50,000.
Sharewell HDD LLC is marking its 30th anniversary in 2014. A company born out of the Texas oilfields and at the knee of the then-fledgling horizontal directional drilling (HDD) industry, the pioneering HDD tooling and service provider has definitely earned its stripes through its years of innovation and expertise.
The unsung hero in CIPP projects is the stuff that makes it stick to the wall of the pipe — the resins.Since 1959, Interplastic Corp. has been manufacturing unsaturated polyester, vinyl ester and specialty resins, gel coats, colorants and putties under the CoREZYN, Silmar and Integrity brand names for the composites and cast polymer industries.
Driveways had been one of the more frustrating obstacles Lewis Spradlin faced during 22 years of experience installing propane services. Spradlin, co-owner of D&D Gas in Jacksonville, Fla., explained, “Sometimes I’d end up having to put a line all the way around a house because I couldn’t get under the driveway with my excavator.”
Building now to plan for the needs of its population to 2030, York County, S.C., decided to install a new, large diameter, six-mile-long water main, part of which was run under the Catawba River. After a severe drought during summer 2007, a study found that the existing infrastructure within the York County Eastern Water System was inadequate to meet peak demands and would require more reliance on water supply from another utility.
We’re a month into summer but car shows across the country have been in full swing for far longer than that (depending on where you live) and this special section of Trenchless Technology is getting in on the act.We are showcasing just a small sampling of what classic, collectible and cool cars/motorcycles that those in the trenchless industry have.
It’s summer and the temperatures are rising. Employers need to ensure that their employees are not getting beat by the heat.
More than 166 windmills, 300 megawatts, 140,000 homes and just one drill; when the numbers are all added up, they total a successful boring project and installation of Canada’s largest wind energy project to date. In summer 2013, two of North America’s largest wind energy companies — Enbridge and EDF EN Canada — came together to complete a massive alternative energy expansion in Vulcan County, Alberta.
Over years of use, sewer lines suffer damage that can include holes, cracks and erosion. To ensure the continued function and safety of aging collection systems, owners must routinely undertake extensive pipe repairs and rehabilitation. Various technologies are used for this purpose.
Charleston Water System (CWS) is no stranger to using trenchless technology to address its underground infrastructure needs. Recently, CWS employed it once again to structurally rehabilitate 15,600 lf of reinforced concrete and ductile iron sewer and more than 20 manholes.
Subsurface Utility Engineering (SUE) — the term has come a long way since first introduced in Canada back around 2002. The adoption of this practice has set a high but attainable bar for the collection and depiction of existing utilities. This was the goal — achieve a common standard that could be followed regardless of state and provincial boundaries.
The success of a recent water main replacement in Moorhead, Minn., backed by positive readings from a digital pressure and pullback monitor, helped change some minds about restrained-joint PVC pipe’s resilience in static pipe bursting applications.
Mount Pleasant Waterworks (MPW), the water and wastewater service provider Mount Pleasant, S.C., was presented with a complicated problem: underground force mains in unknown conditions.
Desert Boring Excavation LLC arrives at a hot, sunbaked jobsite. The company has been called in for a utility expansion project in Arizona. The underground construction company is dedicated to locating underground utilities and using HDD technology to improve the infrastructure of the cities and towns in Arizona.
Parents can attest to the fact that when a child hands them a problem, it’s instinctual to try and figure out a way to make things right in the world, even if it means coming out of semi-retirement to do so. Such was the case in 1984 when Tom Sutliff, a salesman for a video inspection equipment company, went to his electrical engineer father with a problem.
